Cranberry Lake Park: Golden Meadows Host Migrators…and Last Minute Mating!

The golden Eastern Meadow at Cranberry Lake Park in early September

Goldenrod! A variety of different Goldenrods gild Cranberry Lake Park in early autumn. Their bounty of nectar and pollen and the insects they attract make Cranberry Lake an ideal stopover for migrating birds and butterflies as they prepare for their long journeys. So cheer for Goldenrods as they feed wildlife, but don’t blame them for your fall allergies – blame ragweed!

Year ’round birds and summer residents have almost finished molting and are also stocking up energy for winter or the migration. And a surprising number of insects are also preparing by busily mating one last time, leaving behind eggs or chrysalises that can bring forth young next spring and summer. Lots going on within this carpet of gold!

Migrating Birds –  Some Stayed All Summer; Some Just Stop Briefly for Rest & Refueling

Now’s the time to train your binoculars on any shaking leaf you see. It might be a fall migrator! Colorful, tiny warblers and vireos that are just passing through on their way south are well worth a pause to look into the shrubbery, as you’ll see below! But don’t forget to wish “bon voyage” to the migrators who arrived last spring and sojourned with us all summer. Many are finishing up their molts and readying for long journeys to the southern US or even Central and South America. We saw all of the birds shown below on the bird walk last week at Cranberry Lake Park.

Migrators from Farther North:  Just Passing Through

The trees are aquiver with fall migrators, travelers that bred up north and only briefly stop to rest and refuel around our woods and meadows. The most colorful ones that we often hear but can’t see are warblers and vireos. These little birds travel on the night wind because it’s safer. Hawks, eagles, and other birds that might see these small birds as food migrate during the day so that they can ride the thermals!

My camera and I are not quite quick enough to catch a lot of these tiny, fast-moving birds. So to share them with you, I’m relying on photos of other photographers with the skills, equipment and sometimes sheer luck to capture these little beauties!

The Blue-winged Warbler (Vermivora cyanoptera) breeds at Cranberry Lake Park, but the birds we’ve seen in the last week were probably moving through from further north. This fine bird shows off its black eyeline and blue wings with white wingbars in a gorgeous photo taken by gifted local photographer Joan Bonin:

Nashville Warbler (Leiothlypis ruficapilla) was also too quick for me.  But here’s one I did manage to catch as it passed through in the autumn of 2016 on its way to Central America.

Summer Visitors: The Migrators that Come Here to Raise Their Young

Some avian migrators see our parks as a great place to raise their young, so they come in the spring and stay for the summer. Having finished breeding and molting, they are now preparing to leave for points south. The male Common Yellowthroat’s  (Geothlypis trichas) “Witchedy – witchedy” song accompanied me often during the summer months as he and his mate raised their young. But you may here his “chuck” call as he hops among the branches stocking up on insect protein before leaving for Florida.

The Common Yellowthroat stops singing its “witchedy-witchedy” song in the fall and prepares to migrate.

Both the male Common Yellowthroat and his mate did a complete molt in July or August and now have fresh feathers for the trip. She’s bit more secretive than the male as she feeds on beetles, ants, bees (!), dragonflies and  grasshoppers within the golden fields. Usually she’ll leave a week or two later than the male.

The female Common Yellowthroat will be around a bit longer than her mate.

Last spring the Wednesday morning birders heard a Black-throated Green Warbler (Setophaga virens) singing its mating song along the Hickory Lane at Cranberry Lake. And this week, the birders spotted one flitting high in the trees. Perhaps it nested here to raise its young, or it could be just passing through our parks in spring and fall. Here’s  a photo I took of a male during the spring migration this year.

The Black-throated Green Warbler may have nested here this summer or he may be just passing through both in the spring and fall.

High in a snag, a Cedar Waxwing (Bombycilla cedrorum) paused briefly to survey the golden eastern meadow one afternoon. Many waxwings go into lower Canada to breed, but I’ve seen successful nests in our parks, too, so this one may have been a summer resident. Some will move south for the winter, but many waxwings will stick around during the cold months.

his Cedar Waxwing may have spent the summer with us or could be migrating south from Canada.

House Wrens (Troglodytes aedon) become quite secretive after breeding. But this one popped out of the greenery for a minute. It appears to have completed the late summer molt and is prepared to start south between now and mid-October.

The House Wren has raised its young here, molted and will be leaving shortly for Florida and other southern states.

A curious juvenile Field Sparrow (Spizella pusilla) peeked at me from dense shrubbery along the trail, too.  The migration of Field Sparrows is not always predictable. Some migrate, some don’t, and some migrate one year but not the next, according to the Stokes’ Guide to Bird Behavior (Vol.2). If this one does migrate, it may join a large flock with Chipping Sparrows as well as other Field Sparrows.

If this Field Sparrow chooses to migrate this year, it will probably join a larger flock. Or it may just stay put!

On one of my Cranberry walks, I spotted some Wood Ducks  (Aix sponsa) far across a well-hidden wetland. They were males who’d chosen this secluded spot to begin their molt out of the summer “eclipse plumage” into their fancy choosing-a-mate plumage. This one looked a bit rough at the moment, but well on his way to his courting colors. As I explained in last week’s molting blog, males molt earlier in the summer to camouflage themselves as females and then molt again in the fall, a time when they compete for a mate to breed with in the spring.

A male Wood Duck almost finished with the molt from his “eclipse plumage” to his courting feathers.

I often hear, but rarely see,  the vireos at Cranberry Lake. But I did get to see a Warbling Vireo (Vireo gilvus) in the spring. A rare treat, since it loves to sing high in the treetops! Its plumage is modest but its song is impressive!  The birders saw one lingering in our park for a while before departing for points south.

Warbling Vireos are often heard high in the trees, but not as commonly seen.

Occasionally I get a quick look at a Red-eyed Vireo (Vireo olivaceus). But Bob Bonin, Joan’s husband and another gifted photographer, got a much better photo than I have so far! This week it too was hanging out with other migrators.

Butterfly Migrators

Birds, of course, are not the only creatures migrating through our parks this autumn. Monarch Butterflies (Danaus plexippus) fluttered everywhere at Cranberry Lake Park in the last few weeks.  This “super-generation” of  fragile creatures – the ones that will fly 3,000 miles to Mexico – were swooping and diving over the meadows at Cranberry Lake, feeding on the acres of Goldenrod. So glad that we provide these master migrators with such a feast!

The tattered Giant Swallowtail (Papilio cresphontes) below looks lightly worn.  Let’s hope that attests to its having mated here this summer after its migration to Cranberry Lake.  These huge butterflies seem to be expanding their range north. Possibly due to climate change, Michigan now often has frost-free Septembers. So if mating was successful, the caterpillars of this very large butterfly may survive inside their chrysalises and hatch in our parks next spring.

This Giant Swallowtail looks a bit tattered at the end of a summer at Cranberry Lake Park. Due to mating? Maybe.

Last Chance for Progeny!  Insects Still Mating in the Meadows

Among the Goldenrod, insects seek out mates in a last ditch effort to leave offspring for next summer. A pair of Goldenrod Soldier Beetles (Chauliognathus pennsylvanicus) rendezvoused on a Bull Thistle  (Cirsium vulgare) – a potentially risky place to mate since a bird might think they make a tasty contrast against the blossom!

Goldenrod Soldier beetles mating on a Bull Thistle

A pair of tiny Pearl Crescent butterflies (Phyciodes tharos) also decided that a warm September afternoon provided the ideal time for mating.

A pair of Pearl Crescent butterflies mating in eastern meadow at Cranberry Lake Park.

And two Ladybugs chased around a Goldenrod stem, one frenetically holding on to the other. I couldn’t really determine whether they were mating or fighting! Clearly, one was more interested in escape and one was in hot pursuit. They were moving too fast for a great shot or a definite identification. My guess is that they were the invasive Asian Ladybugs (Harmonia axyridis). Unfortunately they are more common these days than our native Nine-spotted Ladybug (Coccinella novemnotata) and come in highly variable colors and patterns.

Two ladybugs chased each other around a Goldenrod stem – mating or aggression?

This tiny Red-legged Grasshopper (Melanoplus femurrubrum) had probably spent the night near the stalk of the Common Milkweed (Asclepias syriaca), wisely hidden from predators among its withering leaves. It will molt multiple times before mating and leaving eggs in the soil to emerge next summer.

A Red-legged grasshopper nymph probably spent the night within this Common Milkweed plant.

The edge of a meadow, near a wetland, might be an ideal spot for a female Great Blue Skimmmer dragonfly (Libellula vibrans). She could be spreading her wings in hope of attracting a mate. If successful, the aquatic plants nearby could host her fertilized eggs. Or while waiting for a likely male, she might just have a great perch for hunting unsuspecting prey!

A female Great Blue Skimmer sunned herself on a cool morning, possibly trying to attract a mate – or just hunting for the next unwary insect!

Spider Art On a Misty Morning

Early fall mornings are an excellent time to appreciate the art of the spiders. Warm days followed by cool nights leave heavy dew on spider webs, and when the sun makes them visible, they are dazzling. How about this lovely creation of an Orb Weaver spider (family Araneidae) drooping with the weight of the dew but subtly reflecting the colors of the sun’s spectrum!

The sun reflecting on the dew in an Orb Weaver’s web.

Another intriguing web, though not as beautiful, is cleverly constructed.  The Funnel Web Spider (Circuria species) lays a sticky sheet of web across the grass, which would be difficult to see were it not for the dew. At the edge of the web, it weaves a tunnel where it lies in wait for unsuspecting prey.  Above the sheet, it weaves an irregular network of silk designed to knock flying insects into its sticky net below. You can see the funnel at the back of this web below.

The Funnel Web Spider’s trap for flying insects with a nifty funnel in which the spider can wait for its prey unseen.

Frogs Underfoot!

As I skirted the edge of wetlands one Sunday, it seemed that a frog sprang out of the grass at every step! Most of them were Northern Leopard Frogs (Rana pipiens), their emerald green backs covered with circular black dots outlined in pale gold. Their dark eyes encircled with gold add to their glamour. Pinkish dorsolateral ridges are another distinguishing field mark. They shine like cloisonné in the deep grass!

Leopard frogs big and small sprung out of the grass near wetlands.

Until last week, I’d never noticed Pickerel Frogs (Rana palustris) at Cranberry Lake. These smaller frogs have somewhat rectangular spots that line up along the frogs’ back in neat rows. They are smaller than Leopard frogs. They tend to be brown (though they are sometimes green too), so I’m fairly sure this is Pickerel frog below.

Pickerel Frogs have more rectangular spots in rows down their backs, rather than the more random round spots of Leopard Frogs. So I think this is Pickerel frog, but I’m not positive!

And Finally, the Native Plants that Make It All Possible!

The plants, though not as often noticed by hikers, provide sustenance for all these creatures as the base of the food web. Butterflies sip their nectar. Bees and wasps feed pollen to their young. Other insects munch on leaves or make winter homes in the stalks. Birds, reptiles, amphibians, and mammals eat all parts of plants, or the insects that live on them. So here’s a gallery of  just a few of the plants that, along with the plentiful goldenrods, have bloomed in sun and shade to sustain the beauty and life of Cranberry Lake Park in late summer.

Autumn Mornings:  Not To Be Missed!

Mist rising in a meadow beyond the trees.

On our September bird walk at Cranberry Lake Park, we arrived on a cool fall morning. The previous day had been unseasonably warm, but a north wind sailed in overnight. The cool air had created heavy dew, leaving silver droplets that set the spider webs shining. The morning sun on the moist leaves created the fine mist you see above, rising  from a meadow beyond the Hickory Lane. What a sight! – the makings of future clouds floating like silver smoke above the wildflowers. A wave of migratory warblers and other small birds had arrived on that night wind. The birders watched, binoculars up, as these travelers hopped busily in the branches, feeding on the plenty of insects attracted by fields full of blooming fall wildflowers. And all of this beauty is gratuitous – unearned, just gifted to us if we just put on our shoes and head out the door! Consider escaping from the busy-ness of life for just an hour this week. Let these beautiful fall days lure you to the parks and savor the gifts that nature so generously offers to all of us.

OUT AND ABOUT IN OAKLAND: Shifting Toward Winter at Cranberry Lake Park

What a difference a month makes!  I began a series of visits to Cranberry Lake Park on September 24 and ended on October 25.  I wanted to watch the park change as fall moved toward winter. It’s as if the color slowly leaves the flowers and grasses in the earth, flows up into the trees and then disappears into the black and white of winter. So this time I’m sharing a transition –  who and what is coming and going at this changeable time of year.

Late September:  Flowers Change to Fruit and Seeds

Mackerel sky CL
The meadow at Cranberry Lake in late September

In late September, the meadow was  still green, but splashed with the gold of Showy Goldenrod (Solidago speciosa). A sweeping curve of this beautiful native plant swept around the large thicket of shrubs in the center of the meadow. It was easy to imagine the path of last summer’s winds as it carried the seeds that created this graceful shape.

Showy Goldenrod 2 CL
Perhaps last summer’s winds carried the seeds that created this curving swath of Showy Goldenrod in the meadow.

And a few other flowers hung on in September.  Individual stems of Evening Primrose (Oenothera biennis) glowed gold among the greenery and a few hardy, flat-topped Yarrow stalks (Achillea millefolium) thrust their way above the browning Canada Goldenrod. Late-blooming Sweet Everlasting (Pseudognaphalium obtusifolium) – which some call Cudweed! – appeared as well, its tightly furled white buds just beginning to open in the cool autumn air. (Click on photos to enlarge; hover cursor for captions.)

Wild Grapes, also known as River Bank Grapes (Vitis riparia), hung in clusters on almost bare branches offering a  treat for migrating and resident birds – and a few of us humans as well! A few weeks later they had either fallen to the ground or been eaten right off the vine.

In September, the Staghorn Sumac (Rhus typhina) leaves changed from green to scarlet and the upright plumes of deep red fruits began to form.  One morning, a flock of Black-Capped Chickadees bounced among the branches, foraging either for fruits or the occasional bug. Perhaps they were the ones who stripped the fruit from some of the plumes. Sumac fruits are eaten by many game and songbirds, though normally they’re not a first choice this time of year.

Over the next few weeks, the Goldenrods began to brown and go to seed. Showy Goldenrod seems to start seeding from the top down, week by week. And eventually that golden curve of Showy Goldenrod had turned a seed-rich, but not very attractive, brown.

The golden swath of Showy Goldenrod turns to a brown, seed rich patch.

And despite not being a first choice fruit, the Staghorn Sumac’s seeds had either been eaten on the plant or fallen on the ground to be found by ground feeders.

Staghorn Sumac no seeds
Staghorn Sumacs’ plumes of seed disappeared in mid-October, either eaten by birds or dropped to the ground.

Talk about cool seeds! Looks at these elaborate seed pods of Dogbane/Indian Hemp (Apocynum cannabinum)! Dogbane is related to milkweeds, and like milkweeds the seeds with tufts of hair help the plant float on the breeze to new places. On the left is this red-stemmed, white-blossomed plant in June and on the center and right, the unbelievably long, angular seed pods this week.

Of course,  some seeds are actually a HUGE problem. In autumn, the invasive, tree-killing vine, Oriental/Asian Bittersweet (Celastrus orbiculatus), produces its seductively beautiful yellow and red fruits. This vine encircles the trunks of trees while climbing for the sun. In doing so, it can choke the life out of a tree. If it gets to the top, it can kill the tree by shading it out and/or by making it top heavy and more likely to fall in storms. Unfortunately, hungry birds eat the berries and spread Bittersweet readily through their droppings. PLEASE DON’T PICK THIS VINE OR MAKE WREATHS FROM IT , ETC. Contact the Parks Department if you want some strategies for getting rid of this beautiful “bad guy”!

By late October, the meadow at Cranberry Creek had turned November brown as plants continued to produce seeds.

The meadow at Cranberry Lake had turned an autumnal brown by the end of October.

I did, though, find a few shy Smooth Asters (Symphyotrichum laeve) tucked beneath overhanging foliage, braving the cold with the last of its lavender blossoms.

During  October: A Feast for Migrating Birds!

It’s hard for us to watch the palette of spring and summer fade – but birds? They love it! Warblers and other small visitors who spent their summer raising young in the cool northern reaches of Canada sailed into the park and found a feast! As did our year ’round resident birds.

One of my favorite partakers of fruits and seeds is the tiny Ruby-crowned Kinglet (Regulus calendula) who’s found its way here from around Hudson Bay in Canada – or even farther north. I seem to always miss seeing the ruby crown which the male shows when he’s excited. I guess the birds I’m seeing are either females or males that are just too calm!

Ruby-crowned Kinglet
Ruby-Crowned Kinglets arrived in October to feed and rest on their way south from northern Canada.

One afternoon at Cranberry Lake, the park was filled with White-throated Sparrows (Zonotrichia albicollis). They whisked in and out of shrubs while dashing down into the grass in search of seeds. This one paused just long enough for me to see its yellow lores, the spots at the corner of its eyes. It may have arrived from the UP or the tip of the mitten on its way to points south – not quite as arduous a trip as some migrators have.

White-throated Sparrow 3 CL
White-throated Sparrows have a shorter migration from northern Michigan to just southern Ohio.

This “first winter” White-crowned Sparrow (Zonotrichia leucophrys) was probably born this summer. It will take on adult coloring when it molts next spring into its bright black and white crown that now is brown and gray. This one was feeding avidly on goldenrod seed during its journey from northern Canada to somewhere south of Michigan.

One morning, far up the path in the shadow of trees, a small Hermit Thrush (Catharus guttatus) landed quickly, picked up a bug or fallen fruit from the grass, and took off.  No photo. But here’s one from a previous year with its chocolate brown back and breast smudges. Too bad the Hermit Thrush doesn’t court its mate here, because its song has 3 different phrases with a pause between each. You can hear two versions of it here.

The Hermit Thrush, with its chocolate brown back and smudges on its breast, picked up a few bugs or some  fruit on its way south.

Our birding group saw other migratory birds enjoying the rest and sustenance provided by Cranberry Lake Park, but through our binoculars. They were too far away or too restless for me to capture them with the camera. The little Nashville Warbler (Oreothlypis ruficapilla) is making its way from Canada’s far north  to Mexico or Central America. The Palm Warbler (Setophaga palmarum) stopped by on its journey from Canada to Florida or the Caribbean. And the Yellow-rumped Warbler (Setophaga coronata) has a comparatively short migration from northern Michigan or Canada to just south of Michigan. So as in all of our parks, Cranberry Lake offers much needed R&R for these small seasonal visitors.

During the bird walk, a Sharp-shinned Hawk (Accipiter striatus) swooped into the Hickory Lane on the west side of the park, perhaps chasing a songbird. It flew straight in front of us and quickly disappeared – we think without snagging the bird. Pretty exciting! Sharp-shinned Hawks are smaller and seen less often than the similar Cooper’s Hawk. They usually appear only during migration, so it’s probably headed south by now.  Here’s a link to a photo at Cornell Lab.

A summer resident, the Eastern Towhee (Pipilo erythrophthalmus) called “chewink!” from the edge of the woods one birdwalk morning. When Ben imitated his call,  the male Towhee darted into a nearby bush, intending, I assume,  to check out the competition. Here’s a photo of one from last spring.  (Let’s just say my photo luck was not with me on that bird walk!)

Towhee Draper Pond2
An Eastern Towhee chipped from the forest edge at the end of the bird walk.

So though we miss the flowers, they have done their work. They attracted the right pollinators which helped create the very seeds that feed tired and hungry migrating birds – as well as having provided bees with the makings for the honey that will feed them through the winter, too. As a compensation, color comes to us once more as the trees begin to turn.

Late October:  Winter Resident from the Far North Arrives – and Color Fills the Trees

Just this week, an American Tree Sparrow (Spizelloides arborea) may have flown into Cranberry Lake Park  from the edge of the Arctic tundra! This sparrow, with a spot in the middle of its gray chest and a two-tone bill, loves cold weather. During the summer, Tree Sparrows make elegant nests of ptarmigan feathers right on the ground in the Arctic in order to raise their young. Evidently for a Tree Sparrow, spending the winter in  Michigan  is like going to Florida! Below is the first one I’ve seen this year.

A flock of Eastern Bluebirds (Sialia sialis) did a lot to brighten up the browning of the meadow last week. Most Bluebirds migrate south, but a few actually stay with us all winter, either in family groups or small flocks, as long as there are seeds and berries available. I couldn’t resist taking more than one photo. Their splashes of azure in the field were really cheering on a gray fall day.

Color, of course, is the glory of a Michigan autumn. On September 24, the Hickory Lane still looked green and lush. By October 11, the colors had changed to gold and orange.   And on October 24,  a single glowing Shagbark Hickory (Carya ovata) at the south end of the lane was still shining in the sunlight after most of the other hickory trees began to turn brown.

The maple family contributes lavishly to the beauty of autumn.  On the path to the lake,  a striking leaf from a Red Maple (Acer rubrum) featured some colorful geometry. And nearby, the deeply lobed greenish-white underside of a pale yellow leaf from a Silver Maple (Acer saccharinum) created some contrast. At the lake’s edge, oak and maple leaves formed a scarf of fall color floating on the surface. 

The lake again was filled with migrating ducks and water birds – all much too far out for any kind of shot. Female Wood Ducks (Aix sponsa), Mallards (Anas platyrhynchos) and Mute Swans (Cygnus olor) were among the throng. Here are photos of those birds from  locations where I can get closer to them!

But there were also  Pied-Billed Grebes (Podilymbus podiceps),  and American Black Ducks (Anas rubripes)on Cranberry Lake.  Please click on these red Cornell Lab links if you’d like to see them up close. Let’s hope a viewing deck gets built on Cranberry Lake in the next few years so all of us can get a closer look in person at the water birds that flock to the lake in spring and fall to socialize and feed.

A Different Kind of Transition in the North of the Park

The greatly improved path entering the woods off of 32 Mile Road.

Finally, a wonderful transition is being finished on the trail at the north end of the park. The Parks and Recreation maintenance staff has spent long hours this summer improving the trail from 32 Mile Road into the park.  Instead of an oft-flooded, muddy track, they have laid down a solid surface with periodic drainage pipes running beneath it to keep the new trail from flooding.  You certainly can feel the difference underfoot!  And I imagine equestrians, as well as hikers, will appreciate the improvement. Thanks to Maintenance Foreman Doug Caruso and Maintenance Technician Jeff Johnson for a hard job that, when completed,  should be a great improvement for the park!

Autumn:  Harvest Time for All of Us!

chickadee-eating-seed
Black-capped Chickadee breaking open a seed.

So, just as we humans harvest crops before the snow falls, birds and animals harvest the wild “crops” of the fields – seeds and fruits. Some of them, like Black-Capped Chickadees (Poecile atricapillus), both eat and store them, tucking the seeds into bark where they will find them when snow blankets the meadow. Others, like the Palm Warbler, use them to fuel their flight to warmer climes. Winter residents, like the Tree Sparrow,  will probe the brown goldenrod  for seeds all winter – as well as flocking at your feeder. So when the color drains away, when the leaves are wet and brown underfoot, it may be a comfort to think of the bounty that surrounds us in those dry, drab plants. The brown and gray seeds nourish all kinds of creatures, and guarantee next summer’s bounty of plants. Those dry leaves underfoot dropped when they completed their work of sending sugars to the trees’ roots, ready to fuel next year’s growth. Seeds and falling leaves really are another reason to be thankful as November arrives. Maybe nature deserves a rest after a job well done!

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

Ox-eye Daisies CL
Big, sunny patches of Ox-eye Daisies stare up from the Old Fields of Cranberry Lake Park

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

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.

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

Birds, Amphibians and Reptiles in the Leafy 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.

Painted Turtle male? CL
A Painted Turtle heading back to Cranberry Lake, perhaps after laying eggs in the sandy field?

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!

Eastern Pondhawk3 CL
A female Eastern Pondhawk dragonfly is emerald green, unlike the male who changes from green to blue as it matures.

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.

THIS WEEK AT BEAR CREEK: Story-telling Wildflowers, Solo Fledglings and the Usual Odds ‘n’ Ends

First week of July, the launch point for what I think of as High Summer.

Blog post and photos  by Cam Mannino
Blog post and photos

Though it’s gray and rainy as I write (again!), I’m still anticipating the dry heat of the heart of the season when the Old Fields of Bear Creek are sprinkled with color,  grasses and tall flowers bend and sway in the wind, big nectar-sipping butterflies balance on blossoms and swallows swoop and dive overhead.  Hope springs eternal that we will see more days like the 4th of July weekend, eh?

History as Told by Wildflowers

Botanists use the term “Old Fields” for the largely treeless expanses of Bear Creek when you enter from Snell Road and west of the playground pond.  I love the term because it implies a history and for me, the wildflowers express that history in different ways. Compared to native grasslands, savannas, or prairie, Old Fields typically have an abundance of non-native, often agricultural, plants and a few scattered native plants that recolonized after farming or grazing stopped.

It only makes sense to begin with Michigan’s Native Americans.  Meet Indian Hemp (Apocynum cannabinum).  During its growing season, all parts of this plant are toxic so you and that dog on your leash should leave it alone (in case either of you were tempted to eat it!) What’s historically interesting is that native people figured out that in the fall, when the toxins drained down into the roots, this plant could be harvested usefully. According to Wikipedia, Indian Hemp was  “used as a source of fiber by Native Americans to make hunting nets, fishing lines, clothing, and twine.”   Hemp is still used in similar products today.  I love its dark red stems and tiny white flowers. You’ll find it along the north side of the path that curves down around the vernal pond below the high seating area on the south side of the Park.

indian hemp 1
Native Indian Hemp had many uses for the Indians who harvested it in the fall when the toxins in the plant had drained down into its roots.

When settlers arrived in Michigan, the dry, sunny, sandy soil of these areas of Bear Creek were prairie – tall grasses, a few native trees and native flowering plants.  Those settlers probably saw our native Black-eyed Susan  (Rudbeckia hirta) when they arrived.  And they are still here,  currently growing in profusion up near the benches on the hill at the south end of the park.

Edit:  Ben tells me that many plants in the Aster family (Asteraceae), to which Black-eyed Susans belong, have two different sets of flowers – the big petals are actually individual ray flowers with reproductive parts at the base, and the black center is made of individual disc flowers (the outer ring of disc flowers are flowering in this picture).  Click here for a basic explanation, or here for a more technical explanation. So every apparent “petal,” small and large,  is actually a separate flower, producing its own seed!  Quite an amazing amount of seed production in what looks like one big flower!

black eyed susan
The bright eyes of the native Black-eyed Susan would have been here to greet early settlers.

Another beloved native, Butterfly Milkweed (Asclepias tuberosa) could have greeted those settlers, just as today its hot pink buds burst into orange blossoms in the native bed and here and there in the field west of the Center Pond.  True to its name, last Sunday it hosted a Meadow Fritillary (Boloria bellona).

According to Wikipedia, after the Civil War,  a U.S. farmer and agriculturalist, Timothy Hanson,  is said to have introduced a European grass as a source of  hay and cattle fodder. Today it’s still here and plentiful and is probably named in Mr. Hanson’s honor; it’s called Timothy (Phleum pratense). It’s a beautiful grass but as a European import, it’s less useful to our native wildlife.  Here it is  in flowering mode with showy red anthers (pollen making organs) at Bear Creek at the top of the hill near the seating area again. Like all grasses, Timothy is wind-pollinated and throws copious amounts of pollen to the wind, hoping that a few pollen grains will land on receptive stigmas of another Timothy plant (stigmas are part of the “female” reproductive structures in plants). Since grasses and other wind-pollinated plants don’t need to advertise to pollinators like insects, birds, or bats, their flowers are not very showy, and sometimes plain hard to see!

After two hot days over the weekend, it had finished flowering for the season, a blessing for folks with spring allergies!

Timothy after seeding
Timothy grass finished flowering by this Monday after a warm weekend.

Timothy and other non-native grasses took the place of tall prairie grasses like Big Blue Stem which is slowly returning to Bear Creek after prescribed burns.  Many of our ground-nesting birds like Pheasants, Meadowlarks and Northern Bobwhites prefer these tall native grasses and losing them, as you’ll hear from me often, reduces the biodiversity we were blessed with here. This fall photo at Seven Ponds Nature Center will give you a feel for the height of this tall native prairie grass that  once flourished in Bear Creek and now is making a comeback .

Big blue stem

Farmers were still farming here in the 1940’s, of course,  and like the settlers, they needed pasture, hay and silage for their animals.  These days Butterfly Milkweed has to contend with the Birdsfoot Trefoil (Lotus corniculatus),a plant from Eurasia and Northern Africa,  which farmers probably seeded while creating pasture for sheep and cattle.  It’s a lovely plant up close, though this particular specimen could be a cultivar (a garden version) that snuck in among the others which aren’t quite as regular and glamorous.

But look what happened this year to Butterfly Milkweed in the meadow west of the Center Pond.  You can barely see the orange of the Butterfly Milkweed among the yellow of Birdsfoot Trefoil!

Next week, along with this week’s discoveries, I hope to explore the historical “roots” (as it were) of other native and non-native species in the shady areas of Bear Creek.  I never knew how much history was blooming right under  my nose!

Fledglings and Old Friends

If you walk along the lane of Walnuts (Julgans nigra) at the center of Bear Creek early in the morning or late afternoon, you’re likely to see some very small, a bit rough-around-the-edges fledglings off on their first solo explorations, no adult nearby.  These young birds are notoriously hard to identify because their plumage is often quite different from their parent.  For example, I’m 99% sure this is a baby Bluebird (Sialia sialis) we saw on Sunday, because of its white eye ring, brown speckled breast, and most importantly, the blue feathers in its wing and tail – and also because it’s smaller, curious and has a not-quite-finished look.

But I could be wrong – so feel free to correct me!

Here’s another fledgling high in a walnut tree.  Warblers are particularly hard to identify as fledglings,  but I’m going with a fledgling Yellow Warbler (Setophaga petechia).

fledgling yellow warbler?

Remember the adult version from an early spring post?

One of our faithful birds, here summer and winter, was also hopping around the walnut trunks searching for bugs or places to store big, fat seeds.  Here’s the agile White-Breasted Nuthatch (Sitta carolinensis) in an unusually upright position:

More often, you’ll see a Nuthatch foraging upside down like this:

And a summer visitor was farther out in the small trees just east of the Walnut lane, the russet and black Orchard Oriole (Icterus spurius) with his beautiful yellow-olive mate (not pictured).

The male Orchard Oriole flitted through the small trees with his mate (not pictured) who is yellow and olive green.

Another faithful resident, the American Robin (Turdus migratorius) is beginning a second brood for the year so look for a female, like this one in a red oak this week,  sitting in her nest with just her head and tail showing.

Those Odds ‘n’ Ends

In the north marsh, Reg spotted what looked like an upside-down Snapping Turtle  ((Chelydra serpentina), its light lower shell (plastron) exposed and its legs flopping in the air.  It was very far away and we puzzled over the sight through binoculars, until suddenly the turtle righted itself and we saw two turtles turn and swim away from each other!  Apparently we saw mating Snappers which breed between April and November.  Since the distant white blob didn’t make much of a photo, here’s a reminder of the beak-nosed appearance of this prehistoric reptile.

snapper head on_2
We saw two of these amazing Snappers mating in the marsh about a week ago.

I must admit that the Center Pond is at its most homely right now.  I hope you saw the White Water Crowfoot (Ranunculus aquatilis), an aquatic buttercup, in bloom earlier, because now it’s left mats of brown strings across the surface.  But despite that, we laughed at seeing 14 young Green Frogs (Lithobates clamitans), sitting at attention on that brown surface all over the pond, each in their own separate little territory, probably enjoying the sunlight.  The bright yellow belly and the tympanum (a frog’s eardrum) on the cheek  that’s bigger than the eye tells you this is a young male on a log near the deck.

I marvel at the semi-precious stone appearance of the Amber Snail (genus Succineida) who lives in moist areas – like this one, found on a dewy leaf near the playground pond.

The appropriately-named Amber Snail loves moisture!

Coming Attractions:

July is the month for a beloved non-native wildflower, Queen Anne’s Lace (Daucus carota) and the first blooms and buds are beginning to show among all that tall grass.  I’m glad this is one of the non-native plants that can co-exist with our native ones!

History under our feet, fledglings surveying the park from high in the walnut trees, and all the other pleasures of summer in Bear Creek await you – on the next sunny, breezy summer day that we all hope is just over the horizon!
