Bear Creek Nature Park: Nervous Fledglings Venture Forth and Missing Native Wildflowers Reappear!

/ Cam Mannino / 1 Comment

Monarch heaven! Common Milkweed flourishes in the eastern meadow at Bear Creek Nature Park, providing lots of leaves on which Monarch caterpillars can thrive.

Summer is finally taking hold. Many of the flowers, butterflies and other insects are late this year, but they’re slowly appearing. Warm days allowed fledglings to emerge from their nests and use their tiny wings to pursue their parents into the fields and marshes, begging to be fed. Many of the young birds look a bit shaky out on their own. Parent birds whisk back and forth, beaks lined with seed or bearing a drooping caterpillar.   Wildflowers, long buried under invasive shrubs that were removed last fall, are emerging from the seed bank in all their glory. A time of renewal for sure!

So join me on a virtual circuit of Bear Creek Nature Park – from the meadows, to the pond, through the woods to the marsh and back to monitor the bird boxes.  I’m happy to have you along!

Fledglings Venture Forth into Sunny Meadows

As I began my walk, rambling along the path through the eastern meadow,  I was suddenly aware of  lots of movement and noisy chattering in the bushes and small trees. Little fledglings were perching there, occasionally fluttering and calling, reminding their busy parents to bring them a meal. A little Red-winged Blackbird (Agelaius phoeniceus) struggled up onto a branch near an adult who took off immediately to look for food, leaving the youngster looking just a bit insecure!

A fledgling Red-winged Blackbird seems not quite ready to be alone in the world!

Another youngster perched on a branch seemed on high alert as  it looked out on the meadow.  The striped feathers and the fact that adult Song Sparrows (Melospiza melodia) were nearby makes me think that it’s their fledgling.

A young Song Sparrow looks anxiously off into the distance, waiting to be fed.

On a birding walk a week earlier, Dr. Ben VanderWeide, our township Stewardship Manager, heard the high, wheezy call of the small Blue-Gray Gnatcatcher (Polioptila caerulea). Looking up we spotted a tiny nest near the top of a walnut tree. Two adult gnatcatchers were industriously taking turns bringing food to their young. The left photo shows what we could see of the nest and the parent bird from below, though the group did catch a glimpse at one point of a fluttering wing as a nestling leaned out to get the goodies. I’ve included an earlier photo of an adult  Gnatcatcher as it forages. (Click to enlarge; hover cursor for captions.)

Dragonflies and Damselflies Hover and Dart in the Meadows

Dragonflies maneuver across the meadows, moving up, down and forward, in their search for unwary insects or possible mates. The broken wood of the mowed invasive shrubs makes a handy resting place for them.  A juvenile male Common Whitetail dragonfly (Libellula lydia) rested quite near a more adult one, perhaps learning the ropes? The white patches at the bottom of the hind wings are field marks for the juvenile. When mature, the whole abdomen is covered in  a dusty white, referred to as “prunescence.”

An adult male Common Whitetail uses his white tail to establish his territory.

The male Eastern Pondhawk dragonfly (Erythemis simplicicollis) also found the woody shards a great place to lie in wait. Though the female is bright green all over, the male’s colors transition from a green face, to a blue-green thorax and a slaty blue abdomen. Quite a handsome fellow!

The Eastern Pondhawk male has a green face and blue-green thorax with a lovely blue abdomen.

Lots of orange dragonflies cling to stalks in the meadow grass. They belong to the genus Sumpetrum, but knowledgeable folk in the Facebook group “Odonata of the Eastern United States” inform me that you can only determine the species of orange dragonflies if you have one in hand with a magnifying glass! And of course, I’m never in a summer meadow, it seems, without seeing the striking Widow Skimmer (Libellula luctuosa).

Damselflies seem more likely to prefer shady areas. But I do occasionally see them in tall meadow grass. Here’s a male Emerald Spreadwing Damselfly (Lestes dryas) I saw when wading through deep grass one warm afternoon. Like dragonflies, they consume a lot of mosquitoes, which pleases me and you too, I bet.

The Seed Bank Awakens as Restoration Begins

Perhaps the biggest thrill for me in the meadows this week, though, was the reappearance of long lost wildflowers. Evidently, beneath those invasive shrubs in the meadows near the pond, seeds and small plants of native wildflowers had been waiting for maybe decades while the fields were covered either with grazing fodder for cattle or abandoned to non-native plants. Now the sun and rain have reached the earth over them again and they are making a comeback!

Out in the meadow west of the pond,  large patches of Butterfly Milkweed (Asclepias tuberosa) have emerged  where previously we only saw a single plant here or there.  And as you’ll see further down in the blog, the Monarch butterflies are already finding them.

Butterfly Milkweed spreads its brilliant orange in two big patches west of the Center Pond.

A spectacular wildflower blooming this year is one neither Ben nor I have ever seen before in Bear Creek Nature Park – the Michigan Lily (Lilium michiganense) – not to be confused with the non-native tiger lilies or the much less glamorous Orange Daylily (Hemerocallis fulva) which originated in Asia. I’d only seen this striking native with its  cup of curved petals, arching stem and showy stigma near the Wet Prairie on the Paint Creek Trail. But this beauty at Bear Creek waited patiently. Once warmth and moisture reached it, up it came just west of the Center Pond.  Michigan lilies can be tempting to hummingbirds and many butterflies. I saw one other bud, so I’m hoping for more!

The dramatic Michigan Lily reappeared in Bear Creek once invasive shrubs were removed.

Tall Meadow Rue (Thalictrum dasycarpum) and Fringed Loosestrife (Lysimachia ciliata)  have staged a comeback, too. A Jack-in-the-Pulpit (Arisaema triphyllum) at the edge of the path had produced its bright green berries on a wide spadix. The berries will turn a brilliant red in the fall.  Who knows what else will emerge over the summer and fall?

Butterflies Arrive – but Not Enough for Me, Yet!

As the mid-summer wildflowers finally begin to bloom, the butterflies are begging to appear.  Sun-loving Butterfly Milkweed hosted a Monarch butterfly (Danaus plexippus) last week. Since this is a female Monarch, we can hope that it will lays its eggs either on the leaves of this milkweed or on one of the many Common Milkweeds in the eastern meadow.

With its long proboscis stuck in a blossom, it appears that this Monarch found the nectar to be just what it needed after its journey to Michigan,

A Silver-spotted Skipper (Epargyreus clarus) took a while to show me the bright white spot on the lower (ventral) side of its hind wing. It looks quite different when the “silver spot” is out of sight!

A very tired, worn, Black Swallowtail sat quietly on the path one afternoon. According to Wikipedia, Black Swallowtails are generally longer-lived than other butterflies, unless subjected to bad weather or deprived of food. We’ve had pretty wild weather and the flowers are behind schedule, so perhaps that took its toll on this unfortunate female.

This Black Swallowtail with worn wings and a ragged swallowtail may have been ready to succumb from bad weather and an insufficient supply of nectar.

The Little Wood Satyr (Papilio polyxenes), though, seemed be just fine as it danced along in its bouncing flight from shade into the sun and back again.

Little Wood Satyrs venture into grassy areas that are near the shade of trees.

On to the Pond and Its Frog Song

White Water Crowfoot , an early summer native, is winding down at the Center Pond as the weather warms.

A few blossoms of White Water Crowfoot (Ranunculus longirostris) still peek from the background of abundant Duckweed (Lemna minor) at the Center Pond. The Northern Green Frogs (Rana clamitans) sprawl comfortably among it, floating at the surface and croaking in their banjo voices to attract mates. Since males have a tympanum (circular hearing device near the eye) bigger than their eyes and a yellow throat, this one staring at me intently was definitely a male.

Frog “talk” this July:

I smiled at this small Midland Painted Turtle (Chrysemys picta marginata) who seemed to be listening to the frogs right along with me. But more likely, it was just basking in the warm sunlight after a cold spring, and trying to ignore the frog voices. It’s decorated nicely with bits of  Duckweed.

Into the Woods

The woods just west of Bear Creek Marsh, now more open since cleared of invasive shrubs

The woods on the east side of the park let in so much more light now that the invasive shrubs have been removed! I keep hoping I’ll see more woodland wildflowers because of it. But deer are plentiful at Bear Creek so that’s a slim hope; they love to eat native plants and young saplings. But a couple of woodland flowers escaped their notice, probably because both of them are a bit fuzzy, which puts deer off:  Enchanter’s Nightshade (Circaea canadensis) and Panicled Tick Trefoil (Desmodium paniculatum). Both thrive in the dappled sunlight of the woods so perhaps I will see them spread as sunlight reaches more of the forest floor.

Panicled Tick Trefoil has tiny hairs on the stem
In the fall, Enchanter’s Nightshade will make prickly seed pods that can be carried by passing humans or animals.

Unfortunately for humans, native Poison Ivy (Toxicodendron radicans) is more abundant in the woods and everywhere else this year. But if you stay on the paths, you’ll be just fine. Look for a three leaved plant on which the center leaf has two “thumbs” but the right and left leaves have only one “thumb” – or look for a vine with that leaf arrangement and reddish “feet” clinging to the bark. Poison ivy isn’t poisonous for animals, though. It produces green berries that turn white in the fall just at the time when other berries are disappearing. So migrating birds gobble them up, enjoying a boost of energy and protein before heading south. Northern Flickers, Bobwhite Quail, Eastern Phoebes, Cedar Waxwings, Woodpeckers, Tufted Titmice, and American Robins all readily eat Poison Ivy berries. Raccoons and deer can eat the whole plant –  and they’re welcome to them, as far as I’m concerned.

Poison Ivy berries feed migrating birds in the fall and the whole plant is browsed by deer and eaten by raccoons!

I followed the song of an Eastern Towhee (Pipilo erythrophthalmus) high in the treetops as I entered the woods. I paused, listened, moved a little – no luck at seeing him in the high treetops. After about 10 minutes of following him from one tree to the next, I gave up and moved on. Luckily, the following week ,the birding group spotted one in the open at Cranberry Lake Park, so at least I can show you a somewhat fuzzy photo of  “the one who got away.”

An Eastern Towhee singing his “Drink your Teeeeeea” song at Cranberry Lake Park after one eluded me at Bear Creek

A Northern Cardinal (Cardinalis cardinalis) sang one of its summer songs repeatedly, but it was also hidden in the leafy branches. It’s a classic, summer moment when this  unmistakable, ebullient call reverberates from the treetops!

Damselflies love the “spotlight effect” they get from the filtered light in the forest.  I came upon a female Ebony Jewelwing (Calopteryx maculata) who seemed to be trying to seduce an oddly unmotivated male.  Each posed on a sunlight leaf, but she would periodically fly briefly onto his leaf,  making him jump off for a few moments.  Perhaps she hoped to be pursued, but it was not happening while I was there. I’m afraid I caught her at an indiscreet moment when she paused to poop a few moments later….

A woodland moth slept soundly on a leaf at the edge of the woods one afternoon.  The caterpillar of the  White Slant-line Moth (Tetracis cachexiata) feeds on all kinds of native trees, so it’s a common moth in woods and forests all over Canada and the US. I love the simple design of its bright white wings and subtle yellow stripe.

The White Slant-line Moth’s caterpillar can feed on lots of North American trees so it’s a common sight in forests.

As I walked off the path in the woods to follow the Towhee, clouds of what I think were Hangingflies (genus Bittacidae) rose from the greenery under my feet. These harmless creatures are a relative of the also harmless Scorpion Fly (family Panorpidae) I saw last year at Bear Creek, named for the upward curve of the male’s abdomen.  Both belong to the order Mecoptera. But the delicate legs of Hangingflies cannot support their body weight! So instead they hang by their front legs beneath leaves and capture aphids, moths and other passing insects with their long back legs! Nature always finds a solution. I felt lucky to find one suspended in a spot of sunlight beneath a grass stem.

A Hangingfly can’t stand on its legs. It hunts by hanging from its front legs and catching other insects with the back ones.

Bear Creek Marsh – Wet, Green and Full of Life

A view of Marsh at Bear Creek looking incredibly lush in mid-summer.

The native Buttonbush (Cephalanthus occidentalis) has round, green buds just waiting to burst into balls of white blossoms in the summer heat. It lines one half of the southern platform overlooking the Bear Creek Marsh.

Buttonbush is about to bloom around the southern platform at Bear Creek Marsh.

Here’s what each of those buds will look like shortly!

Buttonbush Blossom in bloom!

At the northern platform, my husband spotted an adult Green Heron (Butorides virescens) standing among the cat-tails and rushes across from the deck.  It probably had been probing the mud for food.  According to the Cornell Ornithology Lab, it has a wide ranging diet – from frogs to fish, snails, insects –  even rodents! This one took off and landed high in a tree overlooking the marsh.  I just learned from Cornell that Green Herons actually nest in a large fork in a shrub or tree with overhanging limbs to hide the nest from predators like snakes, crows or grackles. I’d love to see the nest or young of this handsome bird!

As usual in the summer, we looked for slow-moving mounds of mud or moss in the water, a sure sign of  Common Snapping Turtles (Chelydra serpentina).  We eventually saw four, a large one and 3 smaller ones.  It helped when the big one raised its head on that long neck.   The snappers weren’t much interested in each other at the moment and spent a lot of time munching on fresh underwater plants.

A Snapping Turtle cruising along in the marsh.

Of course, Red-winged Blackbirds dotted the marsh as well, clinging onto cat-tail stems and trilling.  On my first visit, a female scolded me continually while I sat on the bench.  Eventually, I realized that her nest was nearby when a male appeared with a worm or caterpillar in his beak.  He quickly dropped into the grasses near the water to feed his young.

A week later, I saw a Red-winged fledgling watching a male pick apart a cat-tail for seeds.  The little one tried to do the same but with little success since its cat-tail head had already been mostly eaten. Later the small bird landed on a cat-tail in the distance where the male obligingly stuffed some seeds into its beak, thank goodness!

A fledgling Red-winged Blackbird tries to pick apart a cat-tail like the adults do – but not as successfully.

Down below the platform, the American Bur-reed was in all stages of blooming – from buds to blossoms to fruits.  Marsh plants clean our waterways by storing nitrogen and phosphorus that would otherwise starve the water of oxygen.  And Bur-reed is one of the most effective marsh plants, storing four times more than some other aquatic plants.  Plants like Bur-reed are one of the reasons conservationists value wetlands so highly!

American Bur-reed cleans our waterways by storing the nitrogen and phosphorus in run-off.

As I headed back to the parking lot, I walked back along the boardwalk by the playground pond and noticed a sleepy, nocturnal Gray Tree Frog ( Hyla versicolor) resting peacefully on a lower railing.

Stewardship Fosters Nature Here – and Far Beyond the Township

Thanks for taking a virtual hike through Bear Creek with me.  I find it heartening that the stewardship crew and Dr. Ben are restoring habitat and fostering the wildlife in this park with all of its natural variety.  The invasive shrubs are removed and the seed bank brings back native flowers.  The native flowers bloom and butterflies and other insects thrive by feeding at them.  The nestlings are fed with the insects’ caterpillars and venture out of their nests and nest boxes to soar over the meadows. In the fall, some of them will travel great distances, bringing their beauty and their role in maintaining healthy habitats to places as far away as South America.

The humble bur-reed is allowed to flourish in the marsh. Because it cleans the water as it stores nutrients in its stems and leaves, Bear Creek’s water is healthier as it flows  out of the marsh, eventually reaching Paint Creek.  And the fish and other aquatic creatures and plants there benefit from cleaner water – and on it flows into the intricate, inter-locking systems of the natural world.

Stewardship is a lot of hard work but the reward is that it makes a difference not just in our township, but far beyond.  Wherever the creek’s water flows, wherever native seeds are carried by creatures, wind or water, wherever migrating birds and butterflies travel, a little bit of our township’s stewardship work has played its part in preserving our natural heritage.

Gallagher Creek Park: A Time of Transitions Created by Caring Humans and by Nature Itself

/ Cam Mannino / Leave a comment

Little, busy Gallagher Creek Park has gone through some big changes in the last few years.  The Oakland Township Parks and Recreation Commission made a commitment to provide this densely populated area of the township with a playground for children. And they made it happen very quickly!  Meanwhile,  Dr. Ben VanderWeide, the township Stewardship Manager, set in motion a plan to eliminate large stands of non-native shrubs and begin restoring the fields that surround the new playground.  This spring, he and his crew spent long hours creating and planting an extensive set of native gardens.

So I’ve enjoyed several happy outings at this little green park from late April to late June, observing both the exciting changes initiated by human effort and nature’s annual, sometimes less noticed,  transition from spring to summer. Glad you’re here to share both of them with me.

 

 

The People Factor:  From an Old Farm Field to a Playground Surrounded by Beauty

In the spring of 2015, the restoration of native habitat at Gallagher Creek began with a prescribed burn handled by contractors and supervised by Dr. Ben. Having done a plant survey, he had found many native plants struggling to grow amongst invasives. So in 2015, before the Parks Commission began to consider playground plans, Ben set about removing large stands of aggressive shrubs from the eastern sections of  Gallagher Creek. In the early winter of 2016, he was able to begin planting native seed, using budgeted Land Preservation millage funds and a prairie restoration grant from the US Fish and Wildlife Service – Partners for Fish and Wildlife program. (Click on photos to enlarge; hover cursor for captions.)

From 2016 to 2019, the Parks and Recreation Commissioners and Director Mindy Milos-Dale set about making the playground area a priority project. A professional architect from Professional Engineering Associates (PEA) worked with the Parks Commission and staff to develop a design for the playground, picnic pavilion, and paths that would harmonize with the natural environment. The Township Board’s Safety Paths and Trails Committee worked with dedication to complete the northern paved trail along Silverbell Road that leads into the park and LJ Construction did an excellent job of putting it all together. Now it’s  easier and safer for families to reach Gallagher Creek Park from surrounding neighborhoods. And the stewardship crew, volunteers of all ages, and Dr. Ben set out to surround the playground with an educational garden that can familiarize both children and their parents with lovely plants that are native to our area.

All of the work came to fruition this May when the park was dedicated and the gardens completed.

Nature Begins its Transition at Gallagher Creek

The paths that lead out of the native gardens create a transition from the playground to the natural areas that surround the slides and swings. Right now, the only trail beyond the playground leads to a platform near the creek, but more are planned. So knees cocked high, I waded through the carpet of tall grass and flowers, exploring, watching a wet, cold, spring make the transformation into early summer.

A Cold, Wet Spring at Gallagher Creek: Wildflowers Emerge, the Birds are Fewer than Previous Years, and Insects Not Yet Active

Gallagher Creek ran over its banks after the heavy rains in May

May was wet! Gallagher Creek, normally shallow and wandering slowly through tall grass, flooded over into pools beneath the sheltering willows. Instead of whispering, it burbled along it path toward Paint Creek. The cool temperatures and moisture were perfect for some plants.

The most spectacular spring wildflower was the Yellow Lady Slipper (Cypripedium parviflorum) tucked in near the old stump left of the platform at the creek.  The long purple ribbons on these yellow dancing shoes suit this wildflower’s name just perfectly!

Mayapples (Podophyllum peltatum) erupted from the soil in time to live up to their name, too. They formed a circular carpet out in the eastern field, where Ben had cleared a dense stand of shrubs in a previous year. Mayapples are more commonly seen in wooded areas but this colony of them seems quite happy to be surrounded by tall grass.

Their modest little flowers, which emerge from little “green apple” buds, droop shyly beneath the leaves.

The Mayapple’s flower is hidden beneath its umbrella-like leaves.

Wild Strawberry flowers (Fragaria virginiana) lay hidden in the grass all over the park. Their berries will provide a tasty  treat for all kinds of animals who always get to these berries before I do!

Wild Strawberry flowers are almost constantly underfoot in the natural areas of Gallagher Creek Park in May.

Where Gallagher Creek had flooded , it had left standing water far out in the eastern field. And some little rivulets flow the other way, toward the creek from the marsh near Silverbell Road. So I was glad I had waterproof hiking shoes. All along the creek in May,  golden splashes of Swamp Buttercup (Ranunculus hispidus) shone like little suns from the wet grass. I’ve never seen as many here as I’ve seen this year.

Swamp Buttercup created golden swathes among the wet grass near Gallagher Creek.

When Ben cleared the shrubs, he saved a lovely Nannyberry bush (Viburnum lentago) that can now stand out in the landscape. According to the website Illinoiswildflowers.info, this graceful native shrub or small tree later produces juicy, sweet, purplish fruits that many birds love, including Ruffed Grouse, Northern Bobwhite, Ring-necked Pheasant, Northern Flicker, Gray Catbird, American Robin, Hermit Thrush, Eastern Bluebird, Cedar Waxwing, Rose-breasted Grosbeak, and Purple Finch. It’s also a popular nesting shrub for birds. Sounds like a good one for my yard!

Native Nannyberry produces lovely panicles of creamy flowers and then purplish fruits that the birds love. It’s a nesting shrub for many birds as well.

Oak trees are “monoecious,” meaning they have both male and female flowers on the same tree. The male flowers look like little bright green balls on the long, elegant catkins and the female flowers, which become the acorns, are inconspicuous little blossoms on the same branch. The female flowers are pollinated by the wind, which means a lot of us around here are sneezing in May! And once the male flowers open and shed their pollen, they fall to the ground. Here are the male flowers on an oak at Gallagher Creek Park (maybe black oak, Quercus velutina).

The male flowers on the oak catkins have opened and are releasing their pollen to the wind in hopes that the pollen will find a female flower.

Just a couple of birds kept me company at Gallagher Creek Park in late April and May.  I mentioned in the blog earlier this month that a birder friend sent me a photo of a  Killdeer (Charadrius vociferus) standing over her eggs in the shallow nest she’d scraped in the bare earth. The eggs, however, disappeared without my birder friend or me ever spotting the fledglings. Killdeer nests are awfully vulnerable to snakes, raccoons, coyotes and of course, careless humans! But I’ve learned that the adults can lead newborns to safer territory with water and food on the day they hatch from their eggs. They’re born ready to go. So maybe there are fledglings somewhere on the property being cared for by the male while the female starts a new nest. I hope so.

Last year, the air over the park was filled with swooping and diving Tree Swallows (Tachycineta bicolor). This year, I’ve only seen one or two. It may be that the busy playground has encouraged them to settle elsewhere. Here’s a photo of one high in a tree at Gallagher Creek Park about two years ago, and one on the wing, scooping insects out of the air in the wetland area on the far side of the creek as I’ve seen them doing this year.

 

As Summer Tentatively Arrived More Birds and Lots of Crazy Insects!

Getting to Know a Killdeer, plus Other Avian Visitors

In June, I thought perhaps I was repeatedly seeing  the Killdeer that my birding friend had introduced me to in late April. By June 1, the adult Killdeer had abandoned its first nest and seemed to be striking up a friendship with a local American Robin (Turdus migratorius). The killdeer appears to be the female, since the only other adult killdeer around is usually flying in circles making its piercing territorial call which is the male’s way of protecting his mate’s territory.  (No wonder the second part of the Killdeer’s scientific name is “vociferous”!)  The Robin may have been a female as well, since its head is not as dark as most males. On that June 1 afternoon, these two birds of different species hung out together  in a native bed near the pavilion that hadn’t yet been planted. It was surprising to me that the two of them seemed so relaxed in each other’s presence – especially since killdeer are usually quite excitable. I liked to imagine that perhaps the smaller bird found the Robin’s stolid presence reassuring – or maybe that they were silently commiserating over the difficulties of nesting and raising young!

A week later on June 8, the Killdeer was bobbing along among the newly planted garden where it had visited with the Robin, calling now and then.

The Killdeer explored the plants in the native garden where it had kept company with the Robin a week earlier.

Six days later on June 14, Ben texted that he’d just seen another killdeer nest with four eggs in it. When I went on my own, I couldn’t find it; their nests are notorious for being well camouflaged!  A day later, sharp-eyed Ben texted again to say he’d seen a hatchling coming out one of the eggs! And he sent me this wonderful photo!  Be sure to notice the long beak on this youngster.

My husband and I hurried to the park. At first we only saw the female doing a distraction maneuver near the nest location that Ben had described. She huddled down in the grass and stretched her wings up vertically, spread her tail and fluttered, trying to draw our attention. Killdeer females do this when possible predators approach their young. They want predators to think they are starting a new nest. “Don’t look there! Look over here!”

A female killdeer from behind pretending that she is creating a new nest to distract me from her fledgling young.

This time we saw the baby bird, probably just half an hour out of its egg. We wanted to keep our distance to avoid any further distress for either the fledgling or its mother so no photo. But while we watched, this tiny bird struggled to its feet for a few seconds, then flopped on the ground and fluttered forward a little on its tiny wings. By a few repetitions of this arduous process, it got away from the exposed nest, the eggs and the hot sun and hid under some grass. What a little survivor! We walked away.

That evening, I learned the following  from A Guide to Bird Behavior, Vol. II by Donald W. and Lillian Q. Stokes: “Once the chicks have hatched, the parents lead them gradually to areas with abundant food and some cover…On the first day, the chicks may move up to 120 feet from the nests…Brooding [covering the bird with adult’s body] by one or both parents occurs frequently during the first few days and, of course, during the nights.”  I felt reassured, though I’ve not seen the fledgling since it hatched. Here’s a little Killdeer in a photo taken by iNaturalist.org photographer, Steven Mlodinow. Definitely “aaawww” worthy, I’d say.  Hope someday I get to see one on its feet like this!

The Robin, by the way, may have been staring toward the pavilion because she was contemplating a nest there. Ben reported two adult Robins calmly ignoring humans below as they zipped back and forth bringing food to their young in the rafters of the pavilion. When I visited on June 14, I saw two Robin hatchlings who still needed to grow into their beaks a bit before leaving the nest.  Unlike hatchling Killdeers who leave the nest within minutes,  the Robin nestlings can spend almost two weeks in their nest.

On each visit over the six weeks, I kept hearing the “witchedy, witchedy” calls of the tiny, masked Common Yellowthroat (Geothlypis trichas). Each time, though, the calls seemed to be coming from the wetland on the far side of the creek. But last week, on June 19, I finally spotted one high atop a snag near the marsh along Silverbell Road.

A Common Yellowthroat perched on the top of a tall stump near the marsh.

On that last visit, I also heard a Song Sparrow (Melospiza melodia) trilling its melody and finally spotted it high on a bare limb.  It looked as though it were studying the marsh for insects before singing another “verse.”

A few minutes later, I looked up from a flower to see a Great Egret (Ardea alba) soaring away from the creek and across the marsh. It was gone before I could raise the camera to my eye. So here’s a flying Egret photo taken at Bear Creek marsh a few years ago with a possible mate in the distance.  I hope the flying egret nests near Gallagher Creek this year.

Gallagher Creek’s Wild and Weird June Insects

The natural areas at Gallagher Creek Park bloomed with a few more wildflowers in June. And that prompted visits by a variety of insects. Some I wrote about last week when I reported on native pollinators – bumblebees, sweat bees, leafcutter bees and hoverflies. This week get ready for some hair-raising stories! These insects are colorful and fascinating but come with some pretty fierce behavior!

Thanks to very kind assistance from Dr. Gary Parsons, an entomologist from Michigan State University, I now know that an insect I saw last week is a female Feather-legged Fly, specifically Trichopoda pennipes. These insects mimic wasps.  With their feathery jodpurs, they  sip on nectar, spreading some pollen as they buzz from flower to flower. Their genus also has the unpleasant distinction of laying its eggs in or on other insects. Once they hatch they eat the host! Yuck. According to Dr. Parsons, though, they may play a role in controlling an invasive stink bug because of their parasitic habits. Great looking little critter with a grim reproductive strategy, eh?  (Note the two tiny Hoverflies (genus Syrphidae) mating on these Yarrow blossoms in the background.)

A feather-legged fly which mimics a wasp, pollinates as it sips nectar from flower to flower.

Speaking of Yarrow (Achillea millefolium), the fields at Gallagher are filled with this well-known native plant – and insects are making the most of them! Below, a potential victim of the Feather-legged Fly has come up with a snazzy defense. An insect group called Froghoppers (superfamily Cercopoidea) has a nymph stage that we commonly call Spittlebugs. To protect itself from predators, the nymph pierces the plant stem, feeds on its sap (doing no serious harm) and then excretes a bitter-tasting foam around itself. That keeps the nymph moist, insulates it from cold, and hides it from view  so it can safely metamorphose within its bubbles. This spittlebug seems to have found an exceptionally safe spot beneath an umbrella of Yarrow buds.

The foam of a Spittlebug or Froghopper nymph protects it from view of predators.

Yarrow also hosted a very impressive arachnid.  The long legs stretching down this stalk belong to a Daddylonglegs, also known as a Harvestman (order Opiliones).  Unlike other arachnids, their body segments (cephalothorax and abdomen) are fused together and they have two tiny eyes on top of their heads instead of up to eight for spiders. Quite a specimen, isn’t it?

A lovely plant with the oddly descriptive name of Hairy Beard-tongue (Penstemon hirsutus) played host to an Eastern Carpenter Bee (Xylocopa virginica ) this week. Unlike the Bumblebee which it resembles, it doesn’t have a long tongue to reach into these delicate lavender tubes for nectar. Sometimes the Carpenter Bee has to slit the petals open to reach the pollen in narrow blossoms. I wonder if that’s why this bee solved the problem by choosing  the smaller, shallower flowers?

An Eastern Pondhawk dragonfly (Erythemis simplicollis) rested among the greenery in the eastern meadow. According to the “Bug Lady” at the University of Wisconsin Milwaukee Field Station, the white tip of her abdomen means she’s a female and they can lay up to 900 eggs per day!  Most of the eggs and larvae, of course, will get eaten by fish and frogs.  Dragonflies are flying predators. By snagging other insects from the air, they keep the habitat in balance. And they are such flying aces!

We need a relief from cool but strange insects, right?  So let’s end with a second, closer look at Gallagher’s butterflies, some of which were featured in a slideshow last week.  Here’s another look at the gorgeous Red-spotted Purple buttefly (Limenitis arthemis astyanax), this time with the upper (dorsal) view and the equally dramatic lower (ventral) view.

And here’s the tiny Pearl Crescent, this time with its fuzzy face peering over the edge of a leaf as it flitted about the eastern meadow. The matching orange tips on its striped antennae are nice touches,  aren’t they?

The Silver-spotted Skipper (Epargyreus clarus) is named after the silver patch on the underside of its wings. Its caterpillars protect themselves from predators by creating a leaf shelter by cutting a flap off the edge of a leaf, folding it over and than fastening it shut with silk!

Gallagher Creek Park’s Colorful Future

Non-native Ox-eye Daisies always burst forth in June as they have at Gallagher Creek Park.

Gallagher Creek Park already greets the eye with brightly colored playground equipment and the bright little faces of the children who come each day to enjoy  it. And out in the meadow, both native and non-native wildflowers add their beauty to a park visit.

Imagine the color and variety that will greet us when the native gardens come to full bloom in two or three years! Those sturdy native prairie plants in the playground gardens will eventually survive bright sunlight and droughts without much watering because they take the time to grow long roots before fully blooming. Here’s a slideshow of some of those plants as they’ll look when full grown.   Maybe they’ll set us dreaming about our own gardens!
