Welcome to a new occasional series here at Natural Areas Notebook.
Having spent a year writing “This Week at Bear Creek,” (which continues, but perhaps with a little longer pause between blogs), we decided it would be fun to periodically have a look at other parks in Oakland Township. So this week, please join me as I explore Draper Twin Lake Park.
Getting Acquainted with Draper
Draper Park shares some similarities with Bear Creek – marsh land, birds, wildlife, old fields and trails. But it offers very different opportunities for exploration as well. To me, the park seems to have three distinct parts, each with a different character. The central section is one giant marsh, full of cattails, sedges, muskrat lodges and birds. It stretches from Draper Twin Lake to Inwood Road (where it can be viewed from your car) and beyond.
The east and west sections, which cannot be connected by a trail, have attractions like hiking trails lined with summer flowers leading to a fishing platform on a lake much larger than Bear Creek’s Center Pond, trails around a “floating mat” marsh, a newly planted prairie and as you’ll see, a lively mix of wildlife and plant life. As of April 2016, nearly 80 bird species have been observed at Draper Twin Lake Park.
Here’s a map to get oriented. The green outline is the whole park. You can see the western trail running down to Twin Lake on the left. The purple section at the center is the long marsh and McClure Drain (a marshy creek) running south from the lake. And the trail in the eastern section runs all the way from Inwood Road to Parks Road, and a loop encircles a smaller and quite unusual marsh, passes the newly planted prairie (in light green) and continues through old fields at the eastern edge of the park.
The Western Section: A Winding Trail to the Lake
Look for this sign where Hadden and Inwood meet and you’re at the parking lot on the western end of Draper Twin Lake Park. Until last week, a large Black Walnut (Juglans nigra) stood there, but when a giant limb had to be removed, it was discovered that the whole tree was too fragile to remain. Luckily, I got there there after the limb was removed and before the cutting of the tree and got to see something quite fascinating!
Once the limb had come off the tree, it exposed the winter nest of a Red Squirrel (Tamiasciurus hudsonicus) deep down in the trunk. It was like looking through a window into the hidden world of this chattery, hyper little squirrel! The nest was clearly visible inside, full of pine cones and nut shells. Its winter nut cache was spread out at the bottom of the trunk. Red Squirrels don’t bury nuts like other squirrels but make piles on the surface near their nests. Have a look by clicking on these photos to enlarge them. (Hover with your cursor for captions.)
I’m sorry the tree is gone, but an arborist consulted by the PRC said the tree was too fragile for a parking lot. But at least we got to peak into the life of one squirrel before its nest disappeared! The squirrel, by the way, appears to be exploring another tree nearby.
Along the trail to the lake in late summer, we’ll see some lovely native wildflowers, like Obedient Plant (Physostegia virginiana) and Tall Bellflower (Campanula americana) I saw there last August.
For now, early spring butterflies danced around my feet one morning as I walked. The smallest were a pair of Spring Azures (Celastrina ladon) twirling in a mating dance above the path. Their tiny wings created lavender-blue blurs as they spun around each other. But when they landed for a few seconds, they folded their wings and almost disappeared, matching the beautifully patterned gray undersides of their wings to the nearest twig or leaf for protection. If you click on the leaf photo, just between the wings you can see their lovely blue upper surface. Faint blue stripes on the lower surface of the wings appear in the photo on the twig.
An old friend, a Cabbage Butterfly (Pieris rapae), fluttered along the path as well. This one’s a female since she has two spots on her forewings instead of one, as the male does.
A wee Ruby-crowned Kinglet (Regulus calendula) hopped excitedly in the tree limbs on another morning with the birders. Though I caught a glimpse of his ruby crown through the binoculars, I never caught him showing it off for the camera! You can see what he looks like flashing his ruby crown, though, by clicking on this Audubon link.
Late last week, a male Eastern Towhee (Pipilo erythrophthalmus) on the lake trail was doing a simple “chewink” call (second entry under “calls” at the link) rather than singing like the one I’ll show you below in the eastern part of the park. These birds are particularly susceptible to the predation of cowbirds who lay eggs in their nests. Unlike many birds, they don’t seem to recognize cowbirds eggs or remove them. Cowbirds evolved to follow buffalo herds out west and so had to make use of other birds’ nests in order to move on. But as farming replaced forests in the eastern US, they moved here. According to the Cornell Lab, “In some areas cowbirds lay eggs in more than half of all towhee nests. ”
As I approached the lake, I heard the unmistakable call of a pair of Sandhill Cranes (Grus canadensis). They were blocked from full view through the treetops so here’s a photo from an earlier year in Bear Creek.
Sandhill Cranes mate for life and stay together year ’round. According to Cornell Lab, their young can leave the nest only 8 hours after they are born and are capable of swimming. Ben tells me they nested last year in the marsh on the eastern side of Draper, but I haven’t seen them there yet this year.
While birding on Wednesday, Ben’s group introduced me to a Cooper Hawk’s nest they’d seen the previous month. There appeared to be tail feathers sticking out of the nest.
A few moments later, we were lucky enough to see the hawk itself on a branch near the nest, just carefully keeping an eye on things.
One of the special recreational features of Draper Lake is the fishing dock at the end of the trail. Fishermen tell me they catch Bluegills (Lepomis macrochirus), Crappie (genus Pomoxis), Largemouth Bass (Micropterus salmoides) and Northern Pike (Esox lucius). I just sit on the benches provided and watch for water birds.
On one of my solo trips to Draper, I saw a Great Blue Heron (Ardea herodias) standing among cattails at the far end of the pond, but my camera couldn’t quite reach it. Finally, it took off and I got a slightly blurred photo of its huge, blue wings.
Both Barn Swallows and Tree Swallows swooped and darted on the opposite side of the pond – visible through binoculars but not a camera. I could see two big Canada Geese near their nest – one either moving eggs or feeding young, and the other standing guard.
On Wednesday, one of the birders and I watched Blue Jays (Cyanocitta cristata)apparently courting up in the trees along the trail. What was probably two males bobbed up and down on their thin legs for a female on a nearby branch. According to the Stokes Guide to Bird Behavior (Vol.2), this bobbing “is often done in courtship flocks by more than one bird at a time.” I wonder which male’s bobbing she found most impressive?
Now let’s head off to the eastern part of Draper Twin Lake Park. The western and eastern sections aren’t connected by a trail because of the huge marsh in between. So walk or drive just a short way down the road and you’ll see a small utility building to your left. You can park there.
The Eastern Section: A Special Marsh, a Rolling Prairie and a Circular Path through the Old Fields
The eastern section of Draper Lake is still a “work in progress” and for me, that’s part of what makes it interesting. The trails are still being opened up and the prairie is planted on the northern side. This part of the park offers a peaceful place to hike and would be a beautiful, easy place to cross country ski in the winter.
I usually head off to the west (left of the utility building) on the path pictured above which was recently widened to eliminate woody invasive shrubs like Autumn Olive (Elaeagnus umbellata). At this time of year, it looks a bit rough since the stumps are still visible and brush is ragged from the cutting machine. Ben plans to seed it with Little Blue Stem (Schizachrium scoparium), a native grass, and treat whatever stumps try to re-sprout. The curving sweep of this wider trail get us closer to the marsh – in fact particularly close to last year’s nesting site for Sandhill Cranes. On my first spring visit, a beautiful Great Egret (Ardea alba) rose from the marsh. I didn’t move fast enough for a great photo but here’s one during the summer at Bear Creek Marsh to give you a feel for what I saw.
The open water areas around the edges of the marsh are now filling with various water lilies, sprouting from rhizomes deep in the muck after a long winter. The center area of the marsh has a very special floating sedge mat. The sedge mat is best viewed from the edge of the marsh since walking on it is very precarious and would damage the sensitive plants.
Frogs leapt in as I approached the marsh on my first visit and huge round tadpoles wriggled just under the surface. But they eluded my camera. I did see a blur of blue diving into the water way over on the far side of the marsh and heard the rattling call of the Belted Kingfisher. Glad I had an extra photo of one from Bear Creek!
On my second trip, I came upon a young Snapping Turtle (Chelydra serpentina) who seemed to be making its way over a log. Perhaps it was a female preparing to lay eggs, or maybe it had left the large central marsh for the relative seclusion of this smaller marsh to the east.
This week, Ben saw a Blanding’s Turtle (Emys blandingii) at Draper Lake as well. Last year my husband and I stopped along the paved part of Buell on the way home from Draper to take a photo of this one. We helped it off the road by grabbing its shell at the back and moving it in the direction it was going, as we’ve been taught. Blanding’s Turtles are listed as threatened in Michigan so we want to save as many as we can! Note the yellow chin and neck which is characteristic of these turtles.
Ben and the birders spotted the flight of a Green Heron (Butorides virescens) at this marsh on Wednesday. These short, stocky birds sometimes lure their prey with little sticks or insects and then “zap!” – they catch them with their spear-like bills. Here’s one hunting from a log at Bear Creek.
If you continue on the circular trail in this eastern section, you come to a beautiful sight – the rolling contours of what is about to become a native prairie. Stewardship Manager Ben VanderWeide has been working for two years to turn what used to be an overgrown farm field into the prairie grass and wildflowers that are native to our area. Last fall it was planted with native seed purchased with a grant from the US Fish and Wildlife Service. Maintenance mowing keeps the annual weeds under control for the first two years, so it will take about 3 or 4 summers before it looks like a full-3blown prairie. These sunny native plants like to sink their roots deep before they flower. I can’t wait to see what comes up this spring, though.
At the western edge of the prairie, eagle-eyed Ben spotted a migrating Palm Warbler (Setophaga palmarum) twitching its tail feathers in distant brush on the west side of the prairie. Warblers are small and elusive so we birders were happy to know one was passing through on its way to its breeding grounds in Canada.
As you complete the circle, you find yourself in an old field overlooking the eastern edge of the marsh. The center of the marsh, Ben tells me, is a “floating mat” which, according to an article from Loyola University “consists of tightly entangled plants and their roots, mixed with peat.” Apparently, it may look like any other marsh, but water is floating beneath it though plants and even bushes may be growing on top.
Right now, several Eastern Towhees (Pipilo erythrophthalmus) have begun their burbling song in the trees above the marsh. This one was throwing his head back in full courtship mode! I haven’t spotted any females yet, but I’ll keep looking, since this guy clearly expects one!
Here’s his version of the famous Towhee “Drink Your Te-e-e-e-ea” song. This recording was made by my new birding friend, Antonio Xeira.
Eastern Bluebirds perched and sang (Sialia sialis) high in the trees, too high for a great shot. So here’s a closeup of a male with either nesting material or breakfast in his beak from another spring.
And everywhere at Draper, you now hear the melody of the Song Sparrow (Melospiza melodia). Here’s one in a small tree at Draper this week and another recording of a Song Sparrow that my friend, Antonio Xeira, made with a good directional microphone.
A mighty White Pine ((Pinus strobus) stands sentinel toward the end of this circular trail around the marsh. Draper Twin Lake Park has lots of these native trees; their soft needles make a soft, hushing sound in a breeze.
I look forward to knowing Draper Twin Lake Park better. I’ll keep visiting with Ben’s birding walks, and on my own, watching for spring and summer wildflowers, looking for fish below the dock, water birds in the lake and of course, enjoying the slow coming of that beautiful rolling prairie. Maybe I’ll meet you there some sunny morning, perhaps fishing for bluegills, or strolling the paths, or maybe even on skis some snowy winter day! They’re our parks, after all, so come and explore!
