Cranberry Lake Park: Have Hope! Sure but Subtle Signs of Spring!

The solstice has passed; the days and nights get equal time. But when I’m shivering, my fingers and ears go numb in a stiff  wind, I struggle to hold on to the idea that we’re heading into spring. Until, that is, I head into the parks.

Blog by Cam Mannino

In mid-March,  water birds began splashing down in Cranberry Lake, finding any narrow stretch of open water within the ice sheet. They floated and fed – until one glorious morning, the whole lake turned liquid and bright blue! Migrating flocks honked, chattered and wheeled overhead. Some stopped to rest and feed before heading further north; others explored nesting sites. Our year ’round residents tuned up their spring songs. Territories must be established! Potential mates must be impressed! Best of all, the tiny frogs thawed after their frozen winter state – and now they are  singing! Can genuine spring, with its fulsome birdsong and burgeoning buds be far behind? I think not!

Water Birds Arrive Early, Despite the Ice – and the Muskrats Emerge, too!

It always impresses me that some of the first migrators to arrive in early spring are the water birds! They float, seemingly content, in the icy cracks that form as the sun begins to work on the frozen lake surface. Their cold water strategies involve body fat, oiled feathers, down insulation, and a circulation system which allows cool blood coming up from their feet to pass close to  warm blood traveling down, warming it as it returns to the heart. Below a group of Common Mergansers – black-headed males and brown-headed females –  glided along a thin channel of water on the far side of Cranberry Lake’s iced-over surface.

Common Mergansers – black-headed males, brown-headed females – find a small slit of open water at Cranberry Lake early in March.

Off in the distance, the Wednesday birders spotted the hunched silhouette of a Muskrat (Ondatra zibethicus) perched on the edge of the ice as a goose floated nearby. It slipped in and out of the water, hungry no doubt for food but also for a meager scrap of sunlight after living under the ice all winter!

Two sunny but cold days later, the ice had disappeared and the lake was bright blue and busy with migrating ducks and geese. Two Bufflehead (Bucephala albeola) and a group of Ring-necked Ducks (Aythya collaris)black-and-white males and brown females –   dove and surfaced as they foraged near a Canada Goose (Branta canadensis).

A group of Ring-necked Ducks and two Bufflehead dove and rose next to a Canada Goose as they rested and foraged in the lake.

I got a bit closer to a Bufflehead by checking from the opposite side of the lake. This lone male rocked along on the surface, bobbing under to feed every few minutes. Cornell Lab of Ornithology says Bufflehead accomplish this dive  by compressing their feathers to drive out the air and then pitching forward. A few seconds later, they pop to the surface like a cork and float on.

The Bufflehead dives underwater by pitching forward with its feathers compressed to squeeze out the air, making it less buoyant and able to submerge.

And that same cold morning, what I think was a large muskrat came steaming across the pond toward the eastern side. At the time, I thought this bustling swimmer was a Beaver (Castor canadensis), since there is a large beaver lodge on the western side of the lake. But I’m just not sure of that, so I’m sticking with it being a large muskrat. In the water, its tail looked wide enough to be a beaver, but as it approached the shore, it just didn’t seem to be big enough to be a beaver, unless it was a yearling. And beavers tend to swim with only their heads out of the water. In any case, nice to see this furry fellow plying the pond in the sunshine. What do you think? Big muskrat or young beaver?

The width of this swimmer’s tail made me think this was a beaver, but I think now it was a large muskrat.
From this nearing shore photo, it appears I’ve seen a large muskrat, rather than a small beaver.

Hearing the ancient bugle of the Sandhill Crane (Antigone canadensis), I quickly looked up to see two in the distance, flying into the far end of the lake.  Aren’t we lucky that they breed in our wetlands?

 Spring Songs Signal the Beginning of the Mating Season

As I approached the park one icy afternoon, bright spring music reached my ear – Western Chorus Frogs. These tiny frogs (Pseudacris triseriata – about 1.5 inches long!) are daytime relatives of the nocturnal Spring Peepers (Pseudacris crucifer). They spent the winter frozen solid, no heartbeat, no brain activity, but protected by an anti-freeze of sorts that keeps their tissues from breaking down. Pretty amazing! They thaw out and start singing as the days lengthen. The first afternoon I scanned a wetland trying to see these tiny creatures that seemed to be singing right at my feet, but I could not spot one! So on a second try a few days later, I found a log to sit on near the wetland in the trees just east of the parking lot. After about 20 minutes with my binoculars, I finally spotted two (of the hundreds that were probably there!), the sacks beneath their chins bulging, as they tried to impress a female with their piercing calls. Have a look and a listen!

Two tiny Chorus Frogs with bulging necks sing to attract a mate in the shallow water of a wetland.

A male Northern Cardinal (Cardinalis cardinalis) sang from the tree tops in the eastern meadow, turning every few minutes to send his territory call in a new direction. He’s a bit faint on the recording below, so you might need to turn your volume up! I got a bit closer to another male in a bush near the parking lot later on. He was doing “call and response” with another cardinal hidden in the trees nearby.

And of course, the American Robins (Turdus migratorius) that went south to Ohio and Kentucky returned as well, joining the hardy ones that spent the winter here.

One of many Robins that have returned from Ohio and Kentucky to breed here in the summer.

His spring call is also a bit soft.  And he makes a longish pause before his second “tit whoo” call.

Woodpeckers, of course, use drumming to establish territories, rather than singing.  Both male and female Downy Woodpeckers (Picoides pubescens) attract mates and protect territories with drumming. You can hear their typical drum roll in this Cornell Lab recording which was put to use by the little female Downy below.

I get a huge kick out of hearing flocks of American Goldfinches (Spinus tristis) chirp in the shrubs and small trees. To my ear, they are the only bird that actually says “tweet, tweet, tweet!”  Have a listen at this link and see if you agree! The males are currently molting into their bright yellow summer outfits.

Groups of American Goldfinches are singing their “tweet, tweet” calls in Cranberry Lake Park right now.

On a bird walk one Wednesday, we heard the far distant, insistent drumming of a Pileated Woodpecker (Dryocopus pileatus). Mark, one of the great spotters in the bird group, finally located it with binoculars on a very distant tree, and suddenly its mate (we assumed) dove across the trail far ahead of us before slipping up and away between the trees. No chance for a photo.  But here’s an incredible closeup by talented photographer Monica Krancevic at iNaturalist.org.

The First Blooms and Some Sturdy Ferns Wait Patiently

The lovely red blossoms of the Silver Maple (Acer saccharinum) brighten gray days in early spring. They emerge on bare branches before the leaves and are pollinated by the wind before butterflies or other insects emerge and start to pollinate. Those big clusters of scarlet florets are a great food source for hungry squirrels in the spring, when food is scarce, since nuts and seeds are either already eaten or beginning to crack open and sprout.  Last week, I found these male (staminate) clusters fallen from the treetops onto the exposed roots of a large silver maple. I love how the red at the edge of the root echoes the red of the flowers.

The scarlet blossoms of a silver maple are echoed in the root of the tree itself.

Take a closer look at this cluster of florets, some still closed, others waving stamens that have already shed their pollen to wind.  Once pollinated, the female florets will produce winged fruits, called samaras.

A closeup of a cluster of male florets, some closed, some with their stamens already emptied of pollen.

Nearby on the trail to the lake, some sturdy ferns survived the winter with fertile fronds intact.  The brown beads below are the sporangia on the fertile fronds of the Sensitive Fern (Onoclea sensibilis) that carry the spores for this year’s crop of new plants. On the right, are the vegetative fronds that provide sugars through photosynthesis in the summer months.

And the feathery ones below left are the fertile fronds of Ostrich Fern (Matteuccia struthiopteris) whose spores will be released and carried by the wind in the spring. Their vegetative fronds on the right stood tall and bright green, taking advantage of the moist soil and spotty sunshine in the forest.

Spring Just Peeks Out…Here and There

A pair of Canada Geese rest in the quiet refuge of a shaded wetland

Behind a scrim of small trees on the way to the lake, I spotted these two Canada Geese floating serenely in a secluded wetland, away from the noisy flocks gathering on the lake. They reminded me that, at this time of year, spring has to be sought out. It appears and disappears. One day the lake is iced over, a few days later it’s rippling and blue and then the snow falls again. On some days, spring isn’t easily seen – just a few red blossom clusters floating in a vernal pool  or scattered on the lifeless grass. Sometimes spring can only be heard and not seen. Frogs as tiny as your thumb sing unseen one day and the next, perch on a bit of floating grass, their throats bulging with amorous sound. Flocks twitter or honk high in a cold blue sky or male birds rehearse the first tentative versions of their mating songs. Woodpeckers tap out a seductive rhythm on the bark of trees.

The Eastern Meadow at Cranberry Lake doesn’t look very spring-like yet – but the clues are there.

Early spring isn’t flamboyant and colorful, like it will be in a few weeks. It’s hesitant, waiting to be found and enjoyed if we can only slow down enough. If we watch, we’ll see it peeking through the alternating rain or snowfall, cracking and opening in thawing ponds or hear it whistling, chirping, trilling from inside the brush or high in the treetops. So I hope you have time to delight in these  subtle hints of early spring as they unfold. It won’t be long now…

Out and About In Oakland: Stony Creek Ravine – A Park Less Traveled

The diversity of Oakland Township’s parks and natural areas is a source of repeated surprise and delight  for me.

In the last few, very hot weeks, my husband Reg and I have explored the cool, shady trail that threads its way through Stony Creek Ravine Nature Park, a hidden gem that is still under development by the Parks and Recreation Commission. Be prepared to feel you are up north or even out west as you wind your way along a high ridge overlooking the creek.

The 0.4 mile hike isn’t long but it is dramatic. You begin in a tunnel formed by tall shrubs.  Here Reg stops to listen to birdsong as we enter the park.

Birdsong can be heard  all around you when you enter Stony Creek Ravine Nature Park.

Gray Catbirds meow from the thickets, Black-capped Chickadees scold on nearby branches – and birdsong flows down from the treetops, trilled by cardinals and other songsters that I don’t yet recognize by ear.

Chickadee
Black-Capped Chickadees (Poecile atricapillus) search the trees for the insects and spiders that make up most of their diet at this time of year.

Occasionally the trail opens to reveal grassy areas filled with wildflowers.  Ben and his summer technicians have worked hard to restore some of the open areas that once existed here.

Native plants like Bee Balm (Monarda fistulosa) again find a home here as restoration continues in the park.

Mushrooms grow on the moist, steep sides of the ravine. This one appears to be a mushroom from the genus Amanita, mushrooms toxic to humans. Squirrels, though,  eat them with no ill effect.I think a nip’s been taken out of this one, actually.

AManita muscara mushroom SCR
Toxic Amanita mushrooms are perfectly edible for squirrels.

Of course, all the flowers attract the bees and butterflies who share your walk. For a few minutes, a Bumblebee (genus Bombus) seemed to be enjoying riding down thin stalks of Narrow-Leaved Plantain (Plantago lanceolata) in the middle of the trail. This small bee seemed to be working awfully hard for the limited nectar or pollen on these plants. Maybe it was just a youngster having a good time or practicing its technique?

The bumblebee repeatedly rode the stalks to the ground, busily trying to gather nectar and seemingly enjoying the ride.

Where there’s water, of course, there are damselflies. Ebony Jewelwings (Calopteryx maculata) balance on the leaves at Stony Creek Ravine and can be seen in groups down near the water.

The trail winds gently on into the cool shade of an oak forest.

Along the trail, you’ll see the remains of a farmer’s old stone wall, evidence that this land was once more open and sunny than it is today.

The land begins to fall away on either side of the path, plunging dramatically down to Stony Creek as it winds its way through the narrow ravine below. What a view! And the grade is much steeper than a photo can even make it look!

Stoney Creek Ravine
Stony Creek winds its way through the ravine from which the park got its name.

It’s important to stay on the trail here since the stream bed is a conservation area and downhill sliding and slipping causes erosion and damage.  Here are some of our native plants that find a home at the bottom of the ravine, right near the water. (Hover cursor for captions; click on photo to enlarge).

White-Tailed Deer (Odocoileus virginianus) are prevalent in this park. The Parks and Recreation Commission allows controlled hunts in this park every Tuesday and Wednesday from October 1 to January 1, with a PRC-issued special license, to provide opportunity for hunters and to manage the high density of deer in the park. Since the park is closed on those days for 3 months, come visit this slice of dramatic beauty on different days or during the other 9 months of the year .

Deer at SCR second time
Deer hunting is allowed, with a PRC license, Tuesdays and Wednesdays from Oct.1 to Jan.1. No hiking then!

Currently the park’s trailhead is at the end of Knob Creek Drive which is off E. Gunn Road. Right now there is only room for one car to park off-road at the entrance. The PRC applied for a grant to help purchase an adjacent 209 acres to expand this park – an area full of  wildflowers and the wetlands that birds and amphibians love, plus space for plenty of parking off Snell Road.  Fingers crossed that we receive that grant!

The trail takes you to a great vantage point and then ends within the park’s forest of sturdy oaks and their saplings.  When you turn to walk back, you’ll be surprised, I think, by how much you notice that escaped your attention on the way in.  I always am.

Oak Forest at SCR
Large Red and White Oaks stand among smaller trees along the top of the ridge at the end of the trail.

We all probably have our favorite natural areas in Oakland Township.  Mine’s always been Bear Creek Nature Park and yours may be the Paint Creek Trail or Cranberry Lake Park. But it’s exciting to explore the paths “less traveled by” with fresh eyes. Beauty takes so many forms in the natural world and I love being introduced to landscapes nearby that I’ve never seen before. Give it a try. You never know. As poet Robert Frost suggested, taking one of these paths “less traveled by” may make “all the difference.”

OUT AND ABOUT IN OAKLAND: Cranberry Lake Park – Birdsong, Flower-Studded Old Fields and Fancy Bugs

Ox-eye Daisies CL

Strolling through the old farm fields of Cranberry Lake Park in summer is an auditory feast. The  canopied paths and wide open fields as well as the shady, moist wetlands celebrate summer with a full-throated chorus of birdsong – the quick sweet notes of the Yellow Warbler, the high-pitched trill of the American Redstart, the melodious song of the elusive Warbling Vireo. Ben’s birding group reports more than 50 different bird species on one spring visit, more than in any other park in the township. So you’d expect this week’s blog to be filled with bird photos, right?  Uh, not quite.

Version 2
Blog post and Photos by Cam Mannino

Oh, I do have bird photos to share but some will come from other times and places in the township because birding in Cranberry Lake right now is more by ear than by sight. Birds dive into tangled brush or tall grass or disappear among the whispering leaves overhead to make nests, feed young, intent at the moment on propagating their species. So they’re not all inclined to pose for photos.  Luckily, dragonflies, butterflies, grasshoppers – all sorts of insects –  do. And of course summer flowers are very obliging when a breeze pauses for a moment. So let’s set off together with eyes and ears alert to see what this historic farm has to offer.

Axford-Coffin House CL Western facade
The Axford-Coffin House, at one time a working farm and a country retreat, is now surrounded by a 213 acre park.

The lovely Cranberry Lake Farm Historic District on West Predmore Road is a township treasure and listed in the National Register of Historic Places. If you haven’t explored its beautiful grounds, I recommend you begin by taking a visual tour and learning about its history at this link. We, however, are off to explore the southern part of the 213 acre park that once was a working farm.

Out in the Sunny Old Fields

Old Fields Birdsong!

As we head off along the path from the parking lot that’s west of the historic home, we’re surrounded by knee-deep grasses and wildflowers. Tiny Yellow Warblers (Setophaga petechia) are whisking in and out of the large bushes or small trees nearby, still singing their quick “I’m a little sweet” songs as in Antonio Xeira’s recording here. This male with his rust-streaked breast actually paused long enough for a photo!

And another male Yellow Warbler nearby was busying bringing home lunch for his mate or maybe some nestlings in a distant bush.

On three different visits in the last 10 days or so, I heard or saw a male American Redstart singing in the same tree at a fork in the trail. I’m thinking he and his mate must have a nest nearby. For some reason, I’d never seen this bird before and he’s a beauty.  There’s a good closeup of him here at the Cornell Ornithology Lab. His song is thin, high and ends abruptly.  Cornell Lab says its sometimes described as sneeze-like!  Page down at this Cornell link to hear his song.

American Redstart
A male American Redstart sang in the same tree on three separate visits. Wish I could spot its nest!

In the same tree one morning, I saw a Tufted Titmouse (Baeolophus bicolor) swinging at the tip of a branch as it tried to harvest something from among the leaves. At this time of year, omnivore birds like the Titmouse are probably looking for protein for their mate or young, so perhaps he’d found a caterpillar?

As I crossed the southern old field,  going north, two Common Yellowthroats (Geothlypis trichas) announced their territories, calling back and forth across this grassy meadow.

Yellowthroats have the distinction of being one of the first New World birds catalogued in 1766 by Carl Linnaeus, the famous biologist who created the Latin classification system for all life forms. My photo of the Yellowthroat is below but for a clearer photo of this masked bandit, look here on Cornell Lab’s website.

The black-masked Common Yellowthroat is tough to see but easy to identify from its “Witchedy, witchedy” song.

I rarely see Yellowthroats up close but you can hear their “Witchedy, witchedy” songs all over Cranberry Lake Park. Turn your volume up and you’ll hear the singing competition of two males going back and forth twice on my 25 second recording.

Out in the Old Fields:  Wildflowers,  Competing for Space

The old farm fields at Cranberry Lake exemplify the changes that happen over time when forage crops thrive in abandoned farm fields which are also surrounded by neighboring gardens filled with cultivated flowers.

Native plants are certainly here – native Canada Goldenrod will burnish the fields in the fall and other pre-development plants hold their own at Cranberry Lake, too. Here’s a gallery of a few of them. (Click to enlarge; hover cursor for captions)

The rosy stems of native Dogbane or Indian-Hemp (Apocynum cannabinum) will soon be topped with clusters of white flowers. This plant is toxic if eaten but I doubt you or your dog will be tempted.

Dogbane or Indian Hemp
Dogbane, whose stems will get rosier as it matures, is a lovely native plant that is toxic if ingested.

The meadows are full of non-native plants that, over the years,  have found their way into Michigan’s former farm fields. Many of them are good neighbors, existing side-by-side with native plants without crowding out the original inhabitants. I particularly like Orange Hawkweed (Hieracium aurantiacum), also called Devil’s Paintbrush (not to be confused with Indian Paintbrush). It can be problematic but isn’t at this point in Oakland Township parks. The Wildflowers of Michigan Field Guide explains that  the name came from a mistaken belief that hawks ate it to improve their eyesight!

Orange Hawkweed or Devil's Paintbrush
Orange Hawkweed or Devil’s Paintbrush – often confused with Indian Paintbrush.

Other non-natives pop up here and there in the old fields at Cranberry Lake.  Goat’s Beard blossoms open in the early morning and close about noon. And when its blooming season is over,  it makes a huge seed head, like a giant, beige dandelion, which it is doing right now. By the way, the insect on the blossom at left is a Hover Fly (family Syrphidae) which mimics bees or wasps for protection but has no stinger.

Other non-native plants that usually appear singly are White Campion (Silene latifolia) and Rough-Fruited Cinquefoil (Potentilla recta) which is easily confused with some of our native varieties (thanks to Ben for the ID help!).

Of course, invasive non-native plants have also moved into Cranberry Lake. Here’s a native House Wren (Troglodytes aedon), singing from within one of the worst  invasives, the Autumn Olive (Elaeagnus umbellata), a shrub which is native to Asia. These large bushes fix nitrogen in the soil, creating soil conditions unsuitable for native plants. Its berries are spread by birds and animals. It leafs out early and keeps its leaves late into the fall, shading out other plants. In short, it’s one problem shrub! But the Wren is a welcome summer resident  and his beautiful, burbling courting song  (recorded by Antonio Xeira) is much beloved even if it does emanate from an invasive bush.

Singing House Wren

Another serious  invasive shrub grows abundantly in Cranberry Lake, the Multiflora Rose (Rosa multiflora). This admittedly lovely plant loses its appeal when its strong thorns catch your skin, and this gangly shrub happens to be crowding out native plants all over Michigan. That hurts both our plant and wildlife communities by making native species less plentiful and less healthy because they are less diverse. Multiflora Rose was brought to the US from Japan by horticulturists after WWII as a fencing plant and spread quickly from gardens into natural or disturbed areas.  Like the Autumn Olive, it unfortunately can grow in sun or shade and has the same means of competing for space – lots of berries spread by wildlife and leaves early spring to late fall that shade out other plants.

Hairy Vetch (Vicia villosa)  is beautiful, like many invasives, but has a tendency  to spread. It was brought here as forage for animals. It isn’t as invasive as its relative Crown Vetch (Securigera varia), which forms dense colonies that exclude other plant species, but it does form smaller colonies and can be seen along the paths at various places in the park. Here a native Bumblebee (g. Bombus) probes the tube-like flowers with its long tongue.

And nearby, a Seven-Spotted Lady Bug (Coccinella septempunctata), a species introduced repeatedly from Europe to rid crops of aphids, looked for a meal on a fellow European, the Hairy Vetch again!  At least it wasn’t the Harlequin Ladybug/Asian Lady Beetle (Harmonia axyridis) that infested homes a few years ago. Unfortunately, our native ladybugs, the Nine-Spotted Ladybug, (Coccinella novemnotata) are now rare and scientists are not sure why that happened.

Out in the Old Fields: Fancy Bugs!

The sun-drenched Old Fields at Cranberry Lake seem to attract unusually interesting insects, including – wait for it – flies! Yes, I’m aware that flies aren’t as immediately appealing as butterflies or as impressive as dragonflies,  but some really are pretty cool.  Here’s a photo of a Soldier Fly (Odontomyia cincta) exploring the Dogbane. Can you see the black chevrons on his green back and his red head?  Pretty fancy, eh?

Or how about these mating Golden-backed Snipe Flies (Chrysopilus thoracicus)? The male is the smaller one with the much bigger eyes (“The better to find you with, my dear!”).

Of course, butterflies float above these fields as well. This weekend we saw our first Viceroy (Limenitis archippus) of the year. This one had a slightly injured forewing on one side, but was still happily fluttering about the field exploring flowers. Viceroys are often smaller than Monarch Butterflies and have a telltale bar on their hindwing that the Monarch doesn’t have.

What appeared to be a female Black Swallowtail (Papilio polyzenes asterius) hustled from blossom to blossom in the distance last Sunday, never alighting. So here’s an earlier photo from Bear Creek. I could, however, have seen the black form of the female Eastern Tiger Swallowtail which is very similar. 

A female Black Swallowtail fluttered above the old fields at Cranberry this weekend. Or it may have been the black form of a yellow Tiger Swallowtail, too.

And of course we saw the common but lovely Pearl Crescent (Phyciodes tharos), Cabbage (Pieris rapae)and Little Wood Satyr (Megisto cymela) butterflies as well.

One afternoon I saw a quick, snapping, short flight of what looked like a big moth with yellow-ish wings.  It turned out, after I saw it land, that it was a Carolina Locust in flight.  The “Bug Lady” at the University of Wisconsin-Milwaukee website says that “In The Handy Bug Answer Book, Dr. Gilbert Waldbauer refers to these unexpected wing patterns as ‘flash colors’ which, sometimes in concert with flight noises, attract/distract a predator. When the grasshopper lands and tucks in its flying wings, the pursuing predator suddenly can’t find anything that matches its search image.” That was certainly the case for me. It took me a minute to believe that this brown creature at my feet was the one I’d seen flying. Here’s a link where you can scroll down to a photo of one in flight.

Aaah, Out of the Sunlight: The Lake, Wetlands and Shade

Walking on shady paths and passing by wetlands, I naturally come across plants, insects, birds and other creatures that prefer that environment to sunny, open fields. Two Cedar Waxwings landed up in a leafy treetop on Sunday afternoon. My photo that day just doesn’t do justice to this lovely bird, so here’s a photo from another summer. The field marks of this elegant bird are its crest, its black mask, the yellow tip to its tail and a red dot on each wing that looks like red sealing-wax.   And their color does look like cedar, doesn’t it?

The field marks for a Cedar Waxwing are red wax-like dots on each wing, the black mask, the yellow tip of the tail and a soft crest.

Down near Cranberry Lake, three of the Wednesday birders recognized the melodious tune of the Warbling Vireo, here recorded by birder Antonio Xeira. What a lovely song flowing down from the treetops where it stays out of sight,  seeking out caterpillars. I love the contrast in these two song descriptions found at the Cornell Lab website. “The early twentieth century ornithologist William Dawson described the song this way: ‘Fresh as apples and as sweet as apple blossoms comes that dear, homely song from the willows.'” The highly variable song usually ends on a high note, leading the birder Pete Dunne to describe it as sounding “like a happy drunk making a conversational point at a party.” Here’s the closeup photo at Cornell Lab.

An incredible songster, the Gray Catbird (Dumetella carolinensis) makes a pastiche of other birds’ songs and strings them together. Walking past dense, low foliage, you can often heard him singing his avian version of “sampling,” as in this 45 second recording Antonio made on the Paint Creek Trail.

Creatures that Favor Moisture and Shade

Frogs generally love moist surroundings. In summer, though, the beautiful Northern Leopard Frog (Lithobates pipiens) often moves into grassy areas for its meals. One paused at the edge of the trail at Cranberry Lake Park, an emerald green frog with golden eyes and the spots that give it its name. Northern Leopard Frogs have very large mouths and though they usually eat worms, flies and crickets, they have also been known to swallow birds and garter snakes, according to Wikipedia!

Not hard to imagine how the Northern Leopard Frog got its name!

One warm afternoon, I came upon a Painted Turtle trundling along the path toward Cranberry Lake.

I thought at first it was a male, because it had extra long nails which males use to stroke their mates. But I’m not sure, since it may have been a female coming back to the lake from laying eggs in sandy soil out in the fields. A few days later, my husband and I spotted a hole in the meadow edge where it appeared a raccoon might have dug up a batch of  turtle eggs to feed its young!

 Berries in the Shade

Cranberry Lake is of course important because it has a cranberry bog. At the moment, it’s not visible, but the Parks and Recreation Commission’s Master Plan includes construction of an observation deck at the lake in the next couple of years.

But other berries are forming along the shady path toward the pond.  The native Bristly Blackberry bushes are blooming under the trees.  In fact, their flowers are beginning to fade in the heat and the fruits, the blackberries, are forming.

And very near the lake, Ben pointed out Highbush Blueberries (Vaccinium corymbosum) forming in the shade. This is the plant that Native Americans enjoyed and that was domesticated in 1907 to create the blueberries we all enjoy in July.  I’m glad I got a photo, because when I went back a second time, some bird or mammal had already munched some of them.  They don’t wait until their ripe the way we do!  Drat…

Along the Hickory Lane on the west side of the park, I saw fruits forming on False Solomon’s Seal, a native plant that spreads by rhizomes (underground stems) under the trees.

Insects that Have It “Made in the Shade”

Dragonflies patrol along the shady paths as well as the open meadows.  I saw one last week that I hadn’t seen for a long time, a female Eastern Pondhawk (Erythemis simplicicollis). She’s emerald green all over with brown/black chevrons on her tail. According to the “Bug Lady” at the University of Wisconsin Milwaukee,  the male gradually changes from green to blue, starting at the tip of its tail and moving up as it matures! These dragonflies stick close to animals, like us, because we stir up a cloud of biting insects they love to eat. Thanks, Pondhawks! Enjoy an all-you-can-eat feast!

Another dragonfly who seems to frequent moist areas almost exclusively is the Dot-tailed Whiteface (Leucorrhinia intacta). The male looks like he’s wearing a Mickey Mouse mask with his white face and eyes. What I think was his mate landed nearby. I couldn’t see her white face but all of her tail and wing markings and her location near the male would seem to indicate she’s the female.

Damselflies also patrol the paths as you near Cranberry Lake itself. Emerald green seems to be a popular color for creatures who want to disappear from predators in the shade. Here’s one called, appropriately enough, the Emerald Spreadwing Damselfly (Lestes sponsa).  

Below the huge Shagbark Hickories (Carya ovata) on the lane at the western edge of the park, a Virginian Ctenucha Moth (Ctenucha virginica) sailed past and settled on a leaf. I was quite excited to see this moth (which caused a slight blur in the photo), since Ben had helped me identify its spiky caterpillar earlier in the spring. It’s quite common and likes goldenrod nectar. This one might have hatched a bit early in  the heat, since the goldenrods won’t bloom for another month. This elegantly shaped moth with an orange head flashes its metallic blue body when it flies.

A Park for All Seasons

Improvements continue  at Cranberry Lake Park.  The northern most part of the central trail that connects with trails in Addison Oaks county park is being renovated this year (and possibly next) to make it less damp so that hikers, bikers and horseback riders will have an easier time accessing the park. That northern section is full of wetlands, those precious resources that clean our groundwater, store flood waters, feed our wildlife and give shelter to exhausted migrating birds – but they make for wet trails in the spring.

But most of the park is open for your enjoyment year ’round  with migrating warblers in the spring, breeding birds in the summer (and summer concerts on the farmhouse porch), a bright orange glow in late summer and fall as Canada Goldenrod bloom and Monarch butterflies fill the fields traveling south. In winter, its gently rolling meadows might be a place to try out your cross-country skis. And then there’s all that history near the Flumerfelt Barn and historic home. So branch out. Try a new park this summer and see what you and your children can find  to love at Cranberry Lake Park.
