Beauty in Every Season: A Year-End Review of our Parks and Natural Areas

Oakland Township Stewardship Manager Ben VanderWeide and I both got inspired by the idea of a year-end reflection on some of  the remarkable sights in our parks and natural areas over the last year. Nature excels in surprising and delighting any curious observer with its ability to come back from adversity, in some cases to even thrive in difficult circumstances. That ability to keep on growing and creating in the face of any obstacle can be a great inspiration in challenging times.

So as the snow falls, please sit back in a comfortable chair with a warm drink and savor  some highlights from the four seasons of 2017 here in Oakland Township.

Winter 2017: Serenity Rises as the Snow Falls

The Tree Line Between Two Prairies, Charles Ilsley Park

Sometimes we just need a little less hubbub after the holidays and the parks provide a  peaceful escape. In general, the only sounds are the wind in bare branches, the occasional calls of the year ’round birds and the tapping  of energetic woodpeckers foraging in the tree bark. And other times,  when we feel  a bit house-bound and crave crisp air on red cheeks,  a winter walk provides little discoveries unavailable in other seasons. During one deep freeze last winter, the weekly birding group stepped out on the ice at Cranberry Lake to inspect a beaver lodge. And a few weeks later,  I plopped down in the snow for a closer look at 3-D ice dendrites standing upright on a frozen puddle! Folks enjoyed the fine skating rink at Marsh View Park, but some who fancied wild surroundings skated on Twin Lake. On sunny winter days, shadows are always sharp and any spot of color, like the brilliant red of a male cardinal,  catches my  eye in winter’s clear, white light. Hiking in winter can be wonderful; just be sure you’re bundled up for it! (Click on pause button for longer captions.)

Spring 2017: Buds, First Blooms, Migrators Flying in by Night and the Ebullient Symphony of Courting Birds and Frogs

Golden Alexanders carpet the woods near the Wet Prairie along the Paint Creek Trail

Ah, mud-luscious spring! The tiny Chorus and Wood Frogs thawed out after their winter freeze and sang lustily from vernal ponds. In early spring, the birders spotted a crayfish at Bear Creek who’d climbed out of her chimney with eggs under her tail and was lumbering toward the pond. Some spring avian migrators quickly passed through, and we bird watchers were lucky to spot a few special visitors. An unusual American Pipit appeared before my camera lens one afternoon at Gallagher Creek Park on its way to its breeding grounds in the far north. While others, like the Tree Swallow or the Eastern Meadowlark, settled in for the summer to raise their young. After last year’s controlled burn, native Lupines appeared along the Paint Creek Trail. And in May, Ben spotted a rare sight, a frilly spread of rare Bogbean flowers in a kettle wetland at Bald Mountain State Recreation Area off Kern Road. Snow melt and bright green buds always offer an irresistible invitation to come out and join the bustle and music of spring!

Summer 2017: Butterflies Galore as Restored Prairies Began to Bloom

East Prairie Ilsley 2017 (1)

Summer! The very word conjures up a coloring box assortment of butterflies hovering over prairie wildflowers. Birds constructed their nests and later wore themselves out feeding noisy, demanding fledglings. We birders particularly enjoyed close looks at a male Rose-breasted Grosbeak sharing egg-warming duties near a Bear Creek path. The birders laughed in surprise watching  a passive/aggressive pair of Canada Geese successfully discourage the presence of a Green Heron by simply swimming uncomfortably close to it.  A family ambled along a path at Draper Twin Lake Park, headed for a morning fishing expedition.  The birding group, binoculars in hand,  spotted an Indigo Bunting while walking the new paths through the prairies at Charles Ilsley Park, increasingly spangled with colorful native wildflowers as restoration proceeds. A Great Horned Owl stared at the delighted birding group through a scrim of leaves near Bear Creek marsh.  Every path in the township hummed with life during the summer months. But that’s what we all expect of summer, right?

Autumn 2017:  Birds Departed South, and Fall Wildflowers Bloomed

Autumn color at Cranberry Lake Park

Tundra Swans flew in formation overhead,  as migrators of all kinds, like the Hermit Thrush, rode the north wind down to southern climes. But as they departed, nature offered a consolation.  Many native wildflowers bloomed in the cool weather as they faithfully do each year. Asters formed carpets of color everywhere, from meadow to marsh! At the Wet Prairie on the Paint Creek Trail,  tiny Ladies Tresses orchids, Grass of Parnassus with its delicately striped petals, and vivid purple Fringed Gentian intrigued me again by emerging in the chill of early autumn. Native bumblebees pushed their way into Bottle Gentian flowers at Gallagher Creek Park and the Wet Prairie. Butterflies still sipped nectar from late fall blooms. The birders identified ducks of all kinds assembled in rafts on Cranberry Lake. Rattling cries alerted me to the presence of  Belted Kingfishers who scouted for prey at  both Bear Creek’s pond and Cranberry Lake. Ben dipped his net into a marsh at Charles Ilsley Park to show us tadpoles that overwinter on the muddy surface beneath the water. So much life as the year 2017 began to ebb!

Parks Full of Life All Year ‘Round. Aren’t We Lucky?

As a direct result of the foresight of township residents who have supported the Parks Commission and land preservation, native plants, wildlife, birds, and a beautifully diverse combination of habitats are being restored and preserved in Oakland Township. I want to share my appreciation for that foresight and for the hard work and knowledge of Ben VanderWeide (my kind and able supervisor and editor), other parks volunteers, my fellow birders and park staff.  And at the end of the year, I thank all of you who read, comment on and/or follow Natural Areas Notebook. It’s wonderful to be learning more all the time about the natural world – and then to have this opportunity to share what I’m learning with all of you. On to 2018!

Lost Lake Nature Park: Fishers of all Kinds, a Tree’s Generous Afterlife and a Lively Meadow

Fragrant Water Lilies (Nymphaea odorata) in Lost Lake

Lost Lake Nature Park, a small 58 acre park probably best known for its sledding hills, hums with life in every season. Right now, fishers of all sorts – birds, animals and humans – are testing their skills against the fish in its 8-acre kettle lake. In the meadow that slopes upward along the sledding hill, dragonflies bask on dried flower heads in early fall sun while a crane fly dances over the soil, laying her eggs among tall native grasses and bright wildflowers. And deep in the woods that cover the slopes, an old tree stump sustains a vivid collection of life. On every short trip this month, Lost Lake sent me home with a little something special.

Around the Lake: Fishers, Flowers and Frogs

On each of my visits, Green Herons (Butorides virescens) foraged and flew at Lost Lake. On my first visit, a young Green Heron stood at the corner of the dock, surveying the eastern pond in the late afternoon sun. The telltale field marks are the streaked side of its head and breast, its greenish yellow legs and its smaller size. Two adult Green Herons flew overhead, giving their distinctive alarm flight call (at this Cornell link under “advertising call”) and later I saw them more  closely in a wetland down the road. The adults are a bit more glamorous than their young, I’d say.

A mature Green Heron flew to a marsh nearby

On my second visit, the herons were only visible through binoculars on the far side of the lake. But the third time, I was rewarded. A very young green heron, about half the size of an adult, landed in the pond, flew to a mud flat fairly near the dock and began to fish. I watched this skillful youngster successfully snag a meal twice, and then watched as it struggled to swallow its trophies, as you’ll see in the slideshow below. (Use pause button to read longer captions.)

On my last visit, a small green heron again appeared, perhaps the same one, this time flying above the head of a fishing  Great Egret (Ardea alba).

The egret was also a successful fisher, though swallowing took no apparent effort for this elegant bird with a long graceful neck. (Click to enlarge; hover cursor for captions.)

As I was leaving the deck one afternoon, I saw movement out of the corner of my eye. As I turned, an American Mink (Neovison vison) paused at the end of the dock before slipping away into the tall grass. I’d never been that close to a mink before. Quite exciting! Mink always live near water and do lots of fishing, eating crayfish, frogs, and fish as well as rodents and occasionally birds or their eggs. A mink coat, with its dark sheen of guard hairs, looks best on this little creature, I think. Since the mink moved too quickly for a photo, I’ve borrowed one from a gifted and generous photographer at iNaturalist who uses the name DigiBirdTrek.

On two afternoons over Labor Day weekend, human fishers showed up at Lost Lake as well – a threesome one day and a young couple another.  Not sure if they were as successful as the green heron!

Human fishers enjoy Lost Lake as well.

With all those fishers, it’s not surprising that this tiny green frog squeaked and leapt into the pond as I walked off the dock one afternoon. It may have been a young Bull Frog (Lithobates catesbeianus), since it has a fold around the tympanum rather than a ridge running back from the eye, which would indicate a Green Frog (Lithobates clamitans). Small bullfrogs are also more prone to squeaking when alarmed; I’ve never heard a squeak from a small green frog.  I’m open to correction, though, since we can see so little of this small frog.

Admittedly, the pond is not at its best right now in terms of flowers. Many of the water lilies closest to the shore have withered into a brown mass and the brown leaves of some Pickerel Weed (Pontederia cordata) stalks protrude from the water near the shore. But in the distance, the water lilies float on a bed of green (see above) and in some places, the lovely lavender plumes of the pickerel weed still stand tall with their huge, graceful leaves. Along the shore, the sunny ball-shaped heads of Sneezeweed (Helenium autumnale) nod in the breeze near the delicate purple chevrons of Great Blue Lobelia (Lobelia siphilitica).

Down the road, at the same wetland where I saw the mature Green Heron, an elusive family of Wood Ducks (Aix sponsa) caught my eye. On each trip, I’d notice a threesome of young ducks being shepherded by the male parent.  This dad wanted nothing to do with me and quickly herded his family around a bend, or behind greenery at the edge of the water. But one day I was able to catch two fairly good shots of dad and his three offspring.

Into the Woods: A Blackened Stump with Vivid Life and Some Clever Seeds

The path into the woods at Lost Lake in dappled afternoon light

The path into the woods starts at the end of the driveway that runs in front of the caretaker’s home, and you’re welcome to use it.  It’s a short, uphill path that is quite steep at the end and then runs quickly downward as you descend the sledding hill. The forest floor is deep green and beautifully dappled by sunlight.

On the dry, wooded hillsides,  some native grasses and wildflowers are beginning to create and disperse seed. The long graceful pods of Sicklepod (Boechera canadensis), a native member of the mustard family, crack open when dry, releasing a long line of seeds to the wind. Jumpseed (Persicaria virginiana), another native, is appropriately named; according to the Minnesota wildflower site, its seed “jumps off the stem at the slightest touch,” sometimes as much as 10-13 feet. Cluster-leaved Tick-trefoil (Hylodesmum glutinosum) makes cool fruits called loments that have little pods with one seed each that travel by sticking to anything that comes close. And an old fave, Bottlebrush Grass (Elymus hystrix), sends its seeds flying on arrow-shaped “awns” that can actually stick upright in the earth when they land. Plant evolution has produced some very creative ways to spread seed!

At the bottom of the hill, in the deeper shade of a wetland, I discovered an old black stump that hosted a variety of brightly colored life. According to Peter Wohlleben, author of The Hidden Life of Trees, the insect and fungal life of felled stumps and logs help the forest by breaking down the nutrients held in the trees’ wood for hundreds of years. The process of decomposition can take as long as the life of the tree – in the case of oaks, up to 300 years! And eventually those released nutrients feed the tree’s offspring and other trees and plants. Well, this old tree stump, a White Pine (Pinus strobus), was busy doing just that. Its surface presented all kinds of colorful life that was busy working to break down its nutrients or using it for shelter.

A tree stump hosting lots of life in the forest at Lost Lake – harvestmen, ants, moss and mushrooms.

What originally caught my eye was a group of tiny, deep orange/red mushrooms.  I couldn’t determine the species of these mushrooms, though they could be an early stage of the Jack-o’Lantern mushrooms (Omphalotus olearius) featured recently at Bear Creek. A few minutes later a second spot of red caught my eye. A group of Harvesters (order Opiliones, suborder Eupnoi), which are arachnids, but not spiders, scrambled around the inside of the stump. The one below came festooned with tiny bright red mites! And then I spotted a ruby red ant, whose species I was unable to discern.  And a lovely patch of green and orange moss with its sporophytes tipped with the capsules that contain its spores graced the flat top surface like a miniature forest. Quite a colorful bunch of creatures, bryophytes (mosses), and fungi working and living on this old stump!

Down the Hill to the Meadow – Basking Dragonflies, A Dancing Crane Fly, Wildflowers and Native Grasses

A soft lavender bank of Bee Balm (Monard didyma) still blooming near the caretakers’ lawn before you enter the woods

Wildflowers are still blooming in glorious color on the steep sledding hill, the small meadow below it and a short distance from the pond. A few Yellow Coneflowers (Ratibida pinnata) hang on nearby, their drooping petals still golden in early autumn light, along with some Smooth Asters with their dark red or yellow centers (Symphyotrichum laeve). Showy Goldenrod (Solidago speciosa) and Grass-leaved Goldenrod (Euthamia graminifolia), both late summer/autumn wildflowers, are being visited by native bumblebees. Pale/Thin-leaved Sunflowers (Helianthus strumosus), that love the forest edge,  shine bright under the trees as you approach the wood. An Evening Primrose (Oenothera biennis), with its four-parted stigma forming the characteristic x-shape, stands alone at the edge of the parking lot. Near the entrance to the woods, the slender pods of Poke Milkweed (Asclepias exaltata), a milkweed of shady savannas, will eventually dry and break open to release their seeds to the wind. Among the flowers, native grasses sway, like Big Bluestem (Andropogon gerardii) which is now flowering and Indian Grass (Sorghastrum nutans) which has started to form its seeds.

This slideshow requires JavaScript.

Among these grasses, a group of Autumn Dragonflies (Sympetrum vicinum) rested on dried flower heads, needing a bit more sun on cool days. This species has a little cloud of yellow near the base of the hindwing. They hatch out in August and September, providing more late summer color. Mature males are the easiest to spot with their red abdomen. Juvenile males (in closeup below) have a yellow thorax and a yellowish brown abdomen, according to Wikipedia. And the females (second and fourth from the left  in the photo at the far right below) have a brown thorax and a brownish/red abdomen. I find it hard to distinguish between females and juvenile males in Autumn dragonflies,  so feel free to correct me!

One of the oddest sights at Lost Lake occurred on my last visit. I saw something with very long legs dancing vertically, up and down, above small holes in the earth between the grass stems. Eventually, after developing and cropping a lot of photos and doing online research, it became clear that I’d been seeing a Tiger Crane Fly (Tipula dorsalis) laying her eggs in the soil. Taking photos of a crane fly rapidly jumping up and down is a bit challenging, but if you look closely, I hope you can see her curving, vertical body as she pokes the needle-sharp ovipositor at the end of her abdomen into the soil. Her narrow wings and very long legs were splayed in every direction as she danced from one hole to another, laying potentially hundreds of eggs. Click this link  from bugguide.net for a much better photo than mine!

A Tiger Crane fly holds herself vertically as she jumps into and out of a hole in the earth, laying her eggs.

By the way, crane flies are gangly, harmless creatures who can’t bite or sting humans or animals as the unrelated mosquitoes do. Crane flies live only 10-15 days and drink nectar, if they eat all (some don’t!). The only damage they do is in their larval form, when the caterpillars, called “leatherjackets,” do eat some turf grasses and agricultural plants.

The Persistence of Life

Despite the ravages of early September – hurricanes one after another, wildfires, earthquakes – here in the protected natural areas of Oakland Township, life persists. The young green heron successfully fishes its food from among the water lilies. In forest shade, the flowers and grasses produce seed, relying on another spring to foster the next generation. A crane fly dances above the earth, seeing to it that their offspring still float over the grass stalks when summer comes again. And what about us?  Well, of course, we’re members too in that community of life on earth. I like the thought that as you and I foster and nourish that community, we’re doing our part to see that life persists on this little blue planet.

THIS WEEK AT BEAR CREEK: Fall Beauty, Creepy Crawlies and Other Oddities

Bear Creek is busy with autumn. Butterflies sip nectar from late season wildflowers. Bees store up pollen to feed the colony during the winter. Grasses, vines and other plants produce seed heads or berries for next year’s crop, providing food for bird and beast alike. Migrating birds stop by on their way south, eating and resting. Summer’s avian visitors, having raised young here, prepare for departure. Some insects hatch, munch on plants, breed and in turn, become a meal for others. And in moist areas, some life forms emerge that range from just weird-looking to gloriously creepy!

 

Autumn Prep:  Late Season Foraging, Molting and Migrating

One sunny afternoon, a band of Clouded Sulphur butterflies (Colias  philodice) fed and fluttered among the pale lavender blossoms of native Smooth Swamp Asters (Symphyotrichum firmum) just off the Eastern Path. What a sight to watch this small male, its golden wings with bold black edges quivering, as it approached for a sip.

Clouded Sulphurs produce many broods a year and perhaps this couple will produce a chrysalis that will overwinter and open in the spring. I’d love to see one then, since the chrysalis reportedly turns yellow with a pink “zipper” right before the butterfly emerges! The male is the one with black wing bands.

These male (left) and female(right) Clouded Sulphurs may still create a chrysalis from which a caterpillar will hatch in the spring.

Nearby, a small Common Buckeye butterfly (Junonia coenia) was sampling the aster’s nectar as well. Native autumn wildflowers provide such a feast before frost descends!

Monarch Butterflies (Danaus plexippus) are sadly scarce this year after we saw so many at Bear Creek last year.  According to the Michigan State Extension website, a severe March snowstorm in their wintering grounds in Mexico killed 50-70% of the Monarchs before they could migrate! But the birding group was lucky enough to spot a female in the western Old Field, feeding on a native New England Aster (Symphyotrichum novae-angliae).

monarch-on-new-england-aster-1
Despite a rough year for Monarchs, we managed to see one at Bear Creek.

Red-legged Grasshoppers are bouncing out of the grass like popcorn along the paths of Bear Creek. They are in the process of molting five times into bigger and bigger instars.  This one, retreating under a leaf,  isn’t quite adult yet.

red-legged-grasshopper-under-leaf-bc-1
This young Red-legged Grasshopper probably has at least one molt (of five) left before being an adult.

At the Center Pond one morning, a Great Egret (Ardea alba) went fishing before migrating to Florida and the Caribbean. Hikers at Bear Creek report seeing a lot of them in the park in the last few weeks, which is great to hear!  (Click on photos to enlarge; hover cursor for captions.)

Under a bench on the viewing platform, two male Mallards (Anas platyrhynchos ) were developing their mating colors again. They’d spent the last 6 weeks or so in their “eclipse plumage,” when they take on the brown-toned female coloring. As they preened last week, however, an iridescent band of green was developing above their greenish yellow bills. (The females’ bills are orange and black.) I wondered if their flight feathers were most affected by the molt that day, since they didn’t take to the water when I sat down on a bench.

Several days later, I saw a bit of drama featuring these males. One of them had  finished molting into his full mating colors. He “got the girl” and the other didn’t. The mallard couple did a lot of synchronous head bobbing on the deck and then swam off together. The other male was left on the sidelines, I’m afraid. But he may find a mate once his molt is complete. Feathers evidently tell female Mallards something important about choosing a healthy male.

An Eastern Kingbird (Tyrannus tyrannus) periodically sallied forth to capture insects from high above the meadow east of the pond. Here’s a photo from last year so you can see it a bit closer. This solitary bird will spend the winter in a flock, eating fruits along the Amazon River in South America. Sounds like a long trip but a pleasant escape, eh?

A twitching of leaves in the low bushes below revealed the constant tail-wagging of a small brown bird. A migrating Palm Warbler (Setophaga palmarum) moved among the branches with a telltale patch of yellow under its tail and a dark eyeline. It probably spent the summer raising young in Canada’s far north and is on its way to Florida or the Caribbean. In spring, a male’s courting colors are a bright yellow breast and throat and  a chestnut cap.

A migrating Palm Warbler with a yellow patch under its tail will be much more colorful when it passes through in the spring.

What appeared to be a juvenile House Wren chipped and scolded from a nearby shrub as I passed. It looks like a young one, doesn’t it? It’ll be traveling to Florida and the West Indies once it leaves Bear Creek, riding on a North wind toward southern warmth.

wren-juvenile-bc-1
A juvenile House Wren will ride the north wind toward Florida and the West Indies in the next few weeks.

This week the birding group saw several migrators, but I didn’t get great shots. So here are three of last year’s photos of the birds we saw through binoculars this week. You might trying bringing your binoculars when you hike here and take a close look at any small, brownish birds in the bushes. We typically don’t get to see these warblers or kinglets except when they stop in our parks on their  journey north or south. They spend the summer raising young farther north.

At the edge of a wetland, a Spreadwing damselfly with huge blue eyes, which may be  a Spotted Spreadwing (Lestes congener), hung onto a twig. Spreadwings always perch with their wings half open and have pincers at the end of their abdomen – but their individual species names are hard to nail down. So don’t quote me on the name of this blue-eyed, bug-eyed character!

Seeds and Berries Mean Spring Prep, too

Plants pollinated in the summer are beginning to produce the seeds and berries that will guarantee their return next year. At the edge of the woods, False Solomon Seal (Maianthemum canadense)  berries are ripening from mottled pink to red.  Aren’t they pretty?

False Solomon Seal Berries BC
The berries of False Solomon Seal are ripening at the edge of the woods.

An aggressive native vine, Virginia Creeper (Parthenocissus quinquefolia), has thrived this summer and seems to be climbing in dense mats over trees and shrubs all over Bear Creek.  It produces berry-like “drupes” (a fruit with a pit that contains the seed/s)  on bright red stems that eventually turn brown. Many migrating and year-round birds feed on these berries, along with the occasional skunk or red fox.

virginia-creeper-2
Virginia Creeper provides lots of fruit from migrating birds and some animals, too.

Wildflowers are setting seed for next spring and the birds take advantage of that as well.  Here are a few native flowers and their beginnings of seed formation.

And Now for Creepy Crawlies and Other Oddities

Ben’s new Stewardship tech, Heather Herndon, spotted a spectacular creepy creature on a rotting log. It appears to be a Leopard Slug (Limax maximus), a non-native who cleans up dead plants and consumes fungi, some agricultural plants and even smaller slugs! What an odd creature it is!  According to Wikipedia, it is hermaphroditic, which means it carries both eggs and sperm. It does mate, however, exchanging sperm with another slug through a reproductive pore near its right tentacle. How strange is that? Slugs, like snails, are gastropods, but unlike snails, they can’t withdraw into shells. What’s odd, though, is that this slug actually has an internal shell behind its head that seems to be an evolutionary left-over, since it has no apparent purpose. So creepily cool, this one!

On our Wednesday bird walk, we spotted this wonderful web of an Orb Weaver spider.  It was a big web and placed unusually high off the ground. Looks like the spider, who may be that tiny dot at the center,  caught something near the edge of the web.

Cathy Rooney, one of the Park Protector nominees, put up on Facebook a wonderful video she found.  It shows an Orb Weaver working meticulously to create a web just like this one. I found this version at YouTube so it should be accessible to any reader. Great find, Cathy!

Out in the Old Fields, the Common Milkweed (Asclepias syriaca) pods are preparing to break open and release their seeds. But this year, the Large Milkweed Bugs (Oncopeltus fasciatus) hatched in great numbers and are attacking more milkweed pods than usual. These insects inject saliva into the seed with their snout-like rostrum. The saliva dissolves the seed so the insect can vacuum it back up! Milkweeds are toxic and these insects are too once they feed. Their bright red color is believed to ward off predators by advertising that. In these two photos, early “instars” (developmental stages between molts) are on the left, and on the right are later and larger instars and one adult beetle. Thanks to the weather and this spring’s prescribed burn, the Milkweed is plentiful this year too,  so we can hope that bugs won’t wipe out next year’s  crop.

Fungi appeared here and there in Bear Creek after the heavy rainfall. Ben identified this white branching mushroom on a fallen log. It seems to be from genus Clavulina, most likely White Coral Mushroom, Clavulina cristata. Doesn’t it look like a tiny white forest? It’s believed to be mychorrizal, meaning it emerges from fungi underground that surround a tree’s roots and assist the tree in absorbing water and nutrients while the tree feeds the fungi. A beneficial symbiosis.

white-coral-mushroom-clavulina-cristatabc-2
White Coral Mushrooms appeared on a fallen log after the recent downpours.

Like last year, huge fungi formed on the dead tree across from the Playground Pond.  They are clearly some kind of polypore, or shelf mushroom, but I’ve been unable to nail that down. Anyone have a guess? They were so big this year that one of them collected water in which insects swam! On my last visit, though, only one was still on the tree. Either the downpours knocked them off or perhaps children did, like I saw two little boys try to do last year.

Giant fungi formed again this year on a tree across from the playground pond.

A little girl was delighted by finding a common Shaggy Mane Mushroom (Coprinus comatus) in the green grass of the playground field.  It is beautifully ruffled, isn’t it?

It took a while to identify this mushroom, but I’m pretty sure it’s called an Elm Oyster Mushroom (Hypsizygus ulmarius) because they look like this and grow out of Box Elders (Acer negundo) at this time of year, like this one on the Western Slope did.

Autumn’s Bittersweetness

I know some people experience autumn as a somewhat melancholy season – flowers missing petals, tree shedding leaves, birds departing. The park quiets down as birdsong diminishes and the cricket song replaces frog song. Others find the riotous color of fall leaves and the crisp air exciting and invigorating and they love the fall. It can strike me either way, depending on the day.

For those who feel a bit sad at summer’s end, maybe it helps to remember that autumn is just the beginning of a long rest before spring. Trees take a breather from photosynthesis and live down in their roots for several months. Seeds are finding their way to the ground where they’ll reside until sunlight summons their hidden life back to the surface. Some birds, like some humans, depart for the south. But others, like the first little Dark-eyed Junco (Junco hyemalis) we saw this week, are winging their way from the north to spend the winter here where our winter weather suits them just fine.

Junco closeup on ground
Ben spotted our first Dark-eyed Junco of the year while with the birding group at Bear Creek.

If we’re curious and  take the time to look, every season here offers beautiful – and sometimes oddly fascinating – discoveries.  And that cheers me even on the grayest of autumn days.

OUT AND ABOUT IN OAKLAND: LOST LAKE – Big Birds, Big Hill, Big Diversity of Life

Cam walking into BC
Blog and photos by Cam Mannino

Until recently, I’d visited Lost Lake Nature Park (on Predmore west of Cranberry Lake Park) only in the winter and marveled at its amazing sledding hill. I’d spent a delightful snowy afternoon taking action shots of kids and adults as they whizzed by on their sleds during Winter Carnival. Fun place! I’d visited once in spring with  the birders and seen a cloud of Yellow Warblers whisking through the trees at the top of the hill.

But it occurred to me that I didn’t know what this 58 acre park had to offer in the summer. So for the last couple of weeks, I’ve spent quiet hours watching water birds as I explored around the 8 acre “kettle lake.” I hiked up through the woods after a rain and was astonished by colorful mushrooms of all shapes emerging at every turn in the path. I ambled down the sled hill in the sunshine among native wildflowers and swooping dragonflies. Let me show you a sampling of what I found.

Lost Lake Itself and Its Wetlands

lost-lake-w-deck
Lost Lake is a “kettle lake” left by a retreating glacier.

As the audio sign near the lake explains, about 10,000 years ago, an “isolated block of glacial ice melted and filled a depression, or ‘kettle,’ in which it sat.” Kettle lakes are “natural wells, refreshed by groundwater springs.” Wetlands encircle the lake. Right now, the cat-tails and reeds near the water are fringed with early fall wildflowers. A sapphire blue one , with a name that sounds like an exclamation – Great Blue Lobelia (Lobelia siphilitica) creates a striking contrast against the yellow Canada Goldenrod (Solidago canadensis) and Riddell’s Goldenrod (Solidago riddellii).

great-blue-lobelia-ll
Great Blue Lobelia is plentiful on  the southern edge of Lost Lake.

The cheerful blooms of Nodding Bur-Marigold/Nodding Beggar-Tick (Bidens cernua) edge the shore near the floating dock. It’s a native annual that spreads through re-seeding in the fall.

nodding-bur-marigold-ll
Nodding Bur-Marigold, also called Nodding Beggar-tick, is a native annual.

In the water nearby, graceful spikes of lavender rise above the water. These lovely native plants have the unlovely name of Pickerelweed (Pontederia cordata), clearly named by a fisherman who appreciated his catch more than the flowers nearby! Found in “high quality wetlands,” according to the Illinois Wildflowers site, it produces large fruits occasionally eaten by ducks.

This graceful. aquatic native, has the unlovely name, Pickerelweed!

Lavender and yellow seem to autumn’s chosen colors when it comes to wildflowers. The Yellow Coneflowers (Ratibida pinnata) of summer that edge the parking lot are waning and the Smooth Asters (Symphyotrichum laeve) are beginning to emerge among them.

Large portions of the pond are dotted with native Fragrant Waterlilies (Nymphaea odorata). I couldn’t catch their sweet scent, but lots of little creatures – beetles, small bees, flies –  evidently can. These elegant blooms produce abundant pollen. Turtles, beavers, muskrats and the occasional deer wade in to feed on the huge, round leaves.

water-lily-closeup-ll
Fragrant Waterlilies produce abundant pollen for insects and their leaves provide foods for muskrats, turtles and beavers.

According to the Illinois Wildflowers website, Waterlily blooms last 3 or 4 days, but once the petals wither, a fruit develops whose stalk bends downward so it can mature underwater. When the seeds are ripe, they are released and float to the surface where they’re carried by water and wind until they sink to the bottom for germination. I saw new blossoms on every trip because of buds like these (love the  neatly-folded, small green bud below the big yellow one!).

water-lily-buds-ll

[Edit:  I forgot to include a small Green Frog (Rana clamitans[) that I caught peeking from between the lily pads.  Like the juvenile birds who seem to grow into their beaks, I wonder if little frogs like this one need to grow into their enormous eyes! Lovely how the sunset that evening colored its small world.]

green-frog-among-lilypads-ll
A small Green Frog came out from between the lily pads as the setting sun turned the water golden.

Under the water, I saw small fish of various sizes schooling. The audio sign indicates that several different species live in the lake, including bullhead, blue-gills, perch, bass and northern pike. What I saw, I think,  were Minnows (family Cyprinidae).

minnows-lost-lake
Evidently perch, bass, blue-gills and others live in Lost Lake but I  saw only Minnows.

Twice as I approached the lake, I was greeted by the site of large water birds. One morning two Great Egrets (Ardea alba) stood at the eastern edge of the lake.

egret-adult-and-juvenile-ll
What appears to be an adult egret with a juvenile at the eastern edge of Lost Lake.

I thought perhaps the larger was an adult and the much smaller was a juvenile. The larger one preened and both foraged for frogs and small invertebrates in the mud at the edge of the pond. After 20 minutes, the large one took off flying and the small one followed. They simply circled for a few minutes and then landed to eat again. I wondered if the older was helping the younger strengthen its flight muscles for migration. Just a guess, though.

egrets-taking-off-ll
The egrets took off and circled for a few minutes before settling to eat again.

While watching the egrets, a large flock of Canada Geese flew overhead, calling to each other. The egrets looked up and watched, just like I did. (Hover cursor for captions; click on photo to enlarge.)

On my second visit to Lost Lake,  a pair of Sandhill Cranes (Antigone canadensis) waded and foraged in exactly the same area that the Great Egrets had used on my previous visit. Sandhills are grey birds, sometimes with what Cornell Lab calls a “rusty wash.” I’ve read, too, that they use mud to preen which often makes them appear brown. Seeing them dancing gracefully up in the air and floating down when mating in the spring is a sight to behold.

sand-hill-cranes-ll
On the following visit, a pair of Sandhill Cranes foraged in the same area as the egrets.

The Woods: An Oak-Pine Barren

Near the pond, a wide variety of trees tower overhead – Cottonwoods (Populus deltoides), Paper Birch (Betula papyrifera), White Oak (Quercus alba) which is already producing bright green acorns and a variety of pines, including huge White Pines (Pinus strobus). The dry, sandy acidic soil here support an Oak-Pine Barren, a special plant community where the most common trees are widely spaced pines and oaks. To mimic the frequent fires that maintained the open tree canopy, the Natural Areas Stewardship crew burns the woodlands at this park every few years with careful use of prescribed fire.

The path to the woods goes west from the lake, beyond the vehicle barrier signs in front of the Nature Center. Along the way, a native perennial, Bee Balm/Wild Bergamot (Monarda fistulosa) fills a sunny spot along a fence line.

bee-balm-ll

On a moist morning after a downpour, I followed the short path that winds up through the woods toward the top of the sledding hill.

forest-lost-lake
The path that starts west of the lake leads through the woods to the top of the sledding hill.

The warmth and moisture had caused the appearance of an astonishing variety of mushrooms, which are the “fruiting bodies” of the fungi living under the soil. Mushrooms produce the fungi’s spores above the soil surface so that they can be scattered for reproduction. In that way, they are like the blooms of flowers carrying the seeds for next year’s crop. But what a diversity of shapes and colors on one morning alone! Below is a gallery of mushrooms, some beautiful, some homely, but all ready to disperse spores on the same damp morning.

Click on the photos to enlarge but I’m afraid I can only tentatively identify a couple of toxic ones. The tall, thin white one with a cap appears to be an early stage of  the dramatically named Destroying Angel (Amanita virosa) mushroom. It belongs to the toxic genus Amanita, which probably also includes the  red or red-and-white mushrooms pictured hereAnd the green mushrooms on tree bark are probably a shelf fungus called Turkey Tail (Trametes versicolor).

Along with oaks and pines, the woods has many Sassafras trees (Sassafras albidum) with their distinctive 3-pronged leaves that smell like root beer when plucked. Sassafras evidently thrives in the sandy soil which underlies a Oak-Pine Barren like this. Here are the huge leaves of a tiny sapling trying to make the most of the forest light.

sassafras-tree-tiny-sapling-ll

Nearby by, a black lump of mud seemed to jump in deep shade. Looking closer, I spotted a  very small Eastern American Toad nicely camouflaged against the forest floor. See if you can spot it; it took me a minute when focusing my camera!

Here it is up close.

Here’s the little creature up close.

Near the top of the sledding hill, at the edge of the forest, native Bottlebrush Grass makes an appearance. The unusual shape of its “awns” (bristle-like appendages) seems to mimic the pine needles nearby and its pale stalk lights up in the smallest amount of sunlight.

Back Down the Big Hill: Sunshine and Prairie Plants

Emerging from the forest shade and descending into the bright sunlight at the bottom of the hill, you’re suddenly surrounded by dry prairie plants of all kinds. Right now,  plumes of Showy Goldenrod (Solidago speciosa) glow in the fall sunshine and native Bumblebees (genus Bombus) hover among the blossoms, making the most of late-season nectar.

showy-goldenrod-ll

All kinds of native grasses thrive from the top of the hill to the bottom – Big Bluestem (Andropogon gerardii), Little Bluestem (Schizachyrium scoparium) and Indian Grass (Sorghastrum nutans).

Ruby Meadowhawk dragonfly (Sympetrum rubicundulum) kept me company as I descended the hill, even quietly posing for a closeup on a beautiful stalk of Big Bluestem.

ruby-meadowhawk-closeup-ll

What I think was a Violet Dancer damselfly (Argia fumipennis) hovered along the path as well. Damselflies seem to love places where a forest meets an open meadow.

bluet-damselfly-ll
What I think is a Violet Dancer damselfly on a dry grass stalk on the sledding hill at Lost Lake

Stopping back at the lake at the end of one walk, some frantic activity at the edge of the water caught my eye. Amazingly, four pairs of Ruby Meadowhawks were mating simultaneously! Linked together, each of the four pairs rose and fell, quickly dipping into the water and then zooming upward again. Here’s the best blurry photo I could get of the 4 pairs enacting their dragonfly drama.

ruby-meadowhawks-4-mating-ll
Four Ruby Meadowhawk pairs beginning the mating ritual at the same time.

A male begins the mating ritual by grasping onto the female right behind the head with pincers at the end of his abdomen. Then the two bend toward each other so that the female can extract sperm from the male’s abdomen, forming the mating wheel that I posted at Gallagher Creek a few weeks ago. I did get one closeup of one pair showing the male grasping his mate. Quite a sight, eh? Not much romance among dragonflies, it seems – but then they are called “dragon” flies…

In a large White Oak near the pond, the impressive paper nest of Common Aerial Yellow Jackets (Dolichovespula arenaria) hung among the leaves. This Yellow Jacket species is distinct from the ground-nesting Yellow Jackets of the species Vespula with which I’m more familiar. Bald-faced hornets (Dolichovespula maculatamake these gorgeous exposed nests too. But if you look closely, you’ll see that the inhabitants of this one, flying in and out, definitely have the yellow and black pattern of the Yellow Jacket. Isn’t it amazing how these insects chew wood pulp and shape it into these graceful spheres, filled with perfect hexagons and sturdy enough to survive all kinds of summer weather?

Four Seasons of Varied Recreation

I’ve featured here the natural richness of Lost Lake Nature Park.  But beyond wonderful winter sledding (there’s a warming house too!),  other recreational opportunities are also available. Kayaks for exploring the lake more closely can be rented from the Parks Department by registering at least one week in advance. Check info at this link. Whether you rent or bring your own kayak, there’s an easy-to-use launching platform on the floating dock that also makes kayaking easily accessible by people with disabilities.

deck-ll
Kayak launching is easy from the floating dock.

Consider bringing a lunch to eat at the picnic tables in the shade near the water.  Or fish in the sunshine from the floating dock (with a current license, of course).

picnic-area-lost-lake

The house you see from the parking lot is the home of the caretakers’ family and is a private residence.  But on the lower level is the Nature Center which houses a project workroom and  a display of taxidermy which allows children to see a coyote, skunk, owl, fox, heron and others up close.  (Photo,  copyrighted by CMNTv,  is a screen shot from a YouTube video.)

screen-shot-2016-09-14-at-3-48-50-pmThe Nature Center is not open on a daily basis,  though plans are afoot to expand its use with open houses and children’s day-camping.  The PRC contracts with Dinosaur Hill to host field trips for Rochester school children each year.  This year,  area kindergarteners will be invited.

nature-center-ll

Lost Lake has lots to offer in any season.  The PRC holds a variety of events here, including this fall,  Yoga by the Lake, a Marsh Bird workshop, a Pumpkin Bowling Event and more. See the details in the Fall 2016 newsletter at this link.  I hope to explore the edges of the lake and its wetlands in a kayak before winter comes. Maybe you’d enjoy a picnic after fishing, watching water birds or simply gazing into the golden heart of a waterlily. The short, steep trail through the forest to the top of the sledding hill and down will get your heart pumping in shady woodland landscape. Look for the hole of a local Pileated Woodpecker (Dryocopus pileatus) near the top of the hill. Or come sledding on a snowy Friday night under the lights or on a winter weekend afternoon with the kids. It’s your park so I hope you take time to enjoy it!

THIS WEEK AT BEAR CREEK: Birdsong, Blossoms, Babies-Spring!

Spring Beauties
Tiny spring beauties find any sunny spot in the dappled light of the woods to show their delicate faces.

Sunlight is dappling the Oak-Hickory forest at Bear Creek. Tiny Spring Beauties (Claytonia virginica) shine pink and white wherever thin spring sun touches the forest floor. Migrating birds, here for a brief stop before moving north, hop from limb to limb in the treetops, searching for a meal. Some of our summer visitors are exploring for nests around the forest’s vernal pools while others are settling in around the ponds and among the twigs and vines in sunny areas.

A few butterflies and moths flutter through open fields, keeping us company as we walk. Springs bubble up out of the ground and a stream flows through the woods toward the marsh. The haze of green moves up from the shrubs into the trees. In the woods, in marshes and wetlands, in sunny meadows – at last, it’s really spring!

Spring in the Woods

During the night, migrating birds are riding the south wind, finding their way back to Bear Creek.  A busy group of Yellow-rumped Warblers  (Setophaga coronata) chatted and fluttered in the greening forest. They’re on their way north to court and breed among the conifers farther up in Michigan. Some go as far as Hudson Bay or eastern Alaska. Here they’re stocking up on protein for the flight, finding little insects on the branches. Later, in the trees near the Snell marsh, I got a shot of one showing his eponymous “yellow rump” patch. (Click on photos to enlarge; hover your cursor for captions.)

Farther into the woods, near one of the vernal pools we monitored a few weeks ago, two Wood Ducks had arrived from the south and were checking out possible nest holes 25-30 feet up in a snag (standing dead tree.) They prefer the larger holes left by fallen branches. Wood ducks have strong claws on their feet to grasp branches and bark. Later, their 3 day old ducklings  will jump down from those heights into the leaves below unharmed to join their mother foraging in a nearby pond as  seen in this 1.5 minute Youtube video from a BBC documentary.

Down in the vernal pool, beneath the Wood Ducks, stood a graceful, small tree covered in white blossoms, a Juneberry or Serviceberry (Amelanchier sp.).  This native tree produces small fruits that are much beloved by birds and other wildlife.

Plentiful spring rain topped up the vernal pool and a few Wood Frogs (Lithobates sylvaticus) began to sing again.  Mostly, though,  they seem to have found their mates and deposited their eggs on vegetation under the water.

Likewise, the salamanders have finished producing those huge bundles  of eggs that were in the last Bear Creek blog. These nocturnal creatures are now back under logs nearby, waiting to come out and feed at night. Here’s what I think is a small Spotted Salamander (Ambystoma maculatum) that we found under wood in a moist area near a vernal pond.

3 bloodroot
Bloodroot blooms for only 2 or 3 days in early spring and all over Bear Creek’s wood this year.

Under the budding branches of taller trees, all kinds of native plants are finding their way into the pale sunlight. The sunny faces of  Bloodroot (Sanguinaria canadensis) shown in the last Bear Creek blog (left) have finished blooming. But all over the woods you can see their cloak-like leaves which unfold after the flowers drop their petals. In the center, stands the Bloodroot’s “fruit” which now contains its fertilized seeds.

Seed pod of Bloodroot
The fruit capsule of a Bloodroot after the petals have fallen from the flower.

As the tree canopy fills high above, the Bloodroot’s stalk will continue to grow until it forms a little umbrella over the fruit. Eventually the seed capsule will swell and burst, dispersing tiny brown seeds for next year’s crop to be carried underground by ants who relish the elaiosome, a parcel rich in oils and proteins, attached to the seed.  This was a great year for Bloodroot. Successive prescribed burns may have really benefited this little woodland flower.

May Apples (Podophyllum peltatum) are living up to their names. Their umbrella-like leaves shelter a round green bud that resembles a tiny apple. It will bloom into a creamy white flower in a few weeks, still hidden beneath the leaves.

The bud of a May Apple does look like a tiny apple hiding beneath the umbrella like leaves.

An inconspicuous little plant called Pennsylvania Sedge (Carex pensylvanica) is just completing its bloom all over the forest. It appears to be little clumps of grass, but this time of year, this sedge blooms with a little yellow flower. The papyrus that ancient Egyptians used was made from a member of the sedge family.

Pennsylvania sedge Carex pensylvanica
Pennsylvania Sedge looks like clumps of grass in the forest, but is not a grass. It blooms yellow this time of year.

In moist places in the woods, an old friend appeared this week. Jack-in-the Pulpits (Arisaema triphyllum) produce bright red cones of berry-like fruit in the late summer and fall.

Jack in the Pulpit
A small Jack-in-the-pulpit appeared in the woods near Bear Creek marsh.

At the edge of the wood, where it meets the field or the marsh, one of my favorite summer visitors has arrived. The Rose-breasted Grosbeak (Pheucticus ludovicianus), with the striking rosy red patch on his white chest and black and white patterned back, sings at the forest edge near the marsh and the pond. This one hid in a bush when he saw my camera – but kept singing!

And what a song! Here’s a recording in Bear Creek by my friend, Antonio Xeira from the Xeno-cantu website . (Be sure to turn up your volume.)

Here’s bit clearer photo from our home feeder.

Each red patch on the chest of a male Rose-breasted Grosbeak is different so it’s easy to tell one from another.

Some flowers seem to be happiest at the forest edge, too.  Like the shy Common Blue Violet (Viola sororia). Such a pretty little face.

Common violet
Common Blue Violet often appears where the trail meets the edge of tall grass or the woods.

Approaching the pond as you come out of the eastern woods, you begin to see and hear a small stream flowing toward the marsh.  It’s most apparent under the boardwalk at the eastern edge of the Center Pond.

Stream from C Pond to marsh BC
A stream fed by the spring in the Center Pond runs east toward the marsh.

That little stream joins with ground water rising to the surface in the marsh and eventually flows under Gunn Road at the northeast corner of the marsh – becoming the park’s namesake, Bear Creek! I love the sound of running water after a frozen winter!

Spring in the Marshes, Ponds and Vernal Pools

There are babies down near the water. Four young Canada Goose goslings (Branta canadensis) paddled and bobbed between their parents as they surveyed Bear Creek Marsh.

And three small Painted Turtles (Chrysemys picta)crowded together on the tip of a log after rain made the water rise in the Center Pond. Space in the sunshine was at a premium!

These young Painted Turtles found only a tip of a log to bask on after heavy rains.

High above the marsh near Snell Road, the air was full of newly hatched midges and Barn Swallows (Hirundo rustica) swooped back and forth with their mouths wide open gathering them in. Their ruddy breasts caught the evening light at dusk one night and shone like copper. They were much too fast and high for a good shot.  So here’s a link to see one at the Audubon website.

Approaching the Center Pond at a distance one early evening, I saw a Great Egret drifting down to the water. I hurried along with my camera, but a very nice couple, walking and talking, scared him up just as I put the camera to my eye!  Drat. So here’s one of my favorite egret photos from another year. I’m glad to  know they’re still at Bear Creek since I missed them last year.

Spring in the Meadows

While near the Center Pond, keep an eye out for another summer visitor, the Eastern Kingbird (Tyrannus tyrannus), a feisty bird who harasses much larger birds that enter its territory – even hawks and herons!  According to the Cornell lab, “They have been known to knock unsuspecting Blue Jays out of trees.” The Kingbird’s dark head, upright posture and the white tips on its tail make it quickly recognizable. This flycatcher spends the winter eating fruit in South American forests.

The very territorial Eastern Kingbird defends his ground in fields near the Center Pond.

Out in the eastern meadow one morning, a Tree Swallow (Tachycineta bicolor) sang its wonderful liquid song next to the nesting box at the top of the hill. I didn’t see a mate, so he may have been trying to attract one to that suitable home. This photo was taken an hour later as another one swooped for midges above the Playground Pond. I love the distinctive liquid gurgle of their calls.

In the meadow that morning, a Song Sparrow  (Melospiza melodia) had found a small tree near the Tree Swallow. He stood at the very top, threw back his small head, and sang!

The Chipping Sparrow is small and a very snappy dresser.

Some describe its chipping song as sounding like a sewing machine.  Below is another recording at Xeno-cantu by my friend, Antonio Xeira.

Tiny early spring butterflies and moths spin and float along the trails, as caterpillars trundle slowly in the grass below. Here again is the caterpillar of the Virginia Ctenucha Moth but this time I saw it upside down so that its red feet and white tufts were more apparent than its dark upper side with its two faint yellow stripes seen in an earlier blog.

You may remember the Spring Azure butterfly with its gray underside from last week’s post about Draper Twin Lake Park.  Amazingly, at Bear Creek this week, one settled for a quick moment and I got to see the lovely lavender blue of the upper surface of its wings, which I normally see only as a spinning blur when its flying.

The blue wings of a Spring Azure are normally seen only in flight. When their wings close, they are gray with faint blue stripes.

On the trail last week, my husband spotted this tiny moth with about a one inch wingspread. At first I thought it was some sort of fancy fly, but after some research, we learned it was a Grapevine Epimenis Moth (Psychomorpha epimenis). This tiny moth’s caterpillar, as its name applies, uses various grapevines as a host plant.  According to Wikipedia, “The larva [caterpillar] makes a leaf shelter in new foliage by taking the leaf edges, pulling them upward and then tying them together with silk.”

The tiny Grapevine Epimenis Moth breeds once a year and its caterpillars use grape vines as a host plant.

During the recent prescribed burn at Bear Creek, Ben discovered a small spring bubbling out of the earth in the eastern meadow. There’s something magical about water flowing up out of the earth, only to sink and disappear again.

The native plants transplanted to Bear Creek last year from a generous donor are beginning to bloom near the pavilion. The golden Wood Poppy (Stylophorum diphyllum) shone like a little sun of its own in late afternoon light. And another lovely native, new to me, is the wildflower on the right with the unfortunate name of Bellwort (Uvularia grandiflora).  The leaves seem to droop like the lovely flower, though Ben tells me, once blooming is over, they expand, fill out and look lovely for the rest of the summer!

 

Final Note:  Closed Trail

Some of you may have noticed that the trail that wound around the wetland below the south hill is closed.  Five years ago when a management plan was created for Bear Creek, Plantwise, who studied the park and wrote the plan, recommended reducing trail density in the park so that the wildlife would have larger portions of undisturbed habitat.  Also, being near the marsh, the newly closed trail is often soggy with standing water, which which means wet feet for hikers, deep ruts made by bikers and headaches for mowing crews. It also means that when those activities take place on the trail, there’s erosion and the possibility of increased sedimentation in the marsh. As Ben said, “Moving the trail away from the wetland may allow the woodcock and some other birds to breed successfully near that little wetland, instead of using it as a temporary stopover on the way to better habitat.”

So if you start down the south hill below the benches, just take a left into what I’ve always called “the tunnel of trees” and you’ll come out on the south side of the meadow that’s east of the Center Pond.  From there, you can skirt the wetland from the other side and still see the birds at the edge of the marsh and listen to their songs from a nice dry trail. Dry feet and more birds.  Sounds like a workable solution.

Spring All Over Bear Creek

So no matter where you go now in Bear Creek, spring asserts itself. If you settle on a quiet bench by the water, climb a rolling woodland trail or stroll through a sunlit meadow, spring will be singing, flying, fluttering and swimming by and around you. Relish it while it lasts!
