Back to Bear Creek: Surprise! Unusual Sightings of Birds, Bugs and More

Blog Post & Photos by Cam Mannino

The last two weeks at Bear Creek gifted me with some exciting moments – seeing previously unseen birds, witnessing unusual nesting behavior, watching a turtle struggling to bury her eggs and being surprised by a little butterfly I hadn’t seen for years. So though the blog just visited Bear Creek two weeks ago, I wanted to share the bounty I’m enjoying before the season changes much.

Unusual Birds and the Usual Ones Doing Interesting Things!

As many of you know, I’ve been walking in Bear Creek for 25 years and I’ve watched for owls all that time. They spend their days sleeping right next to tree trunks on high limbs, and despite craning my neck for years, I’d never spotted one. But on the first June bird walk, a fellow birder, Bob Bonin,  spotted one high up in a tree near Bear Creek Marsh. Huge, silhouetted against the morning sky, this Great Horned Owl (Bubo virginianus) wasn’t easy to see, much less photograph. But luckily, I got a few shots before he gave the group an annoyed look, lifted his huge body with his massive wings and flew away. Such a thrill! (Click on arrows for slideshow; use pause button for a closer look.)

A bit earlier that morning, we saw an unusual bird at the other end of the size spectrum. A male Ruby-throated Hummingbird (Archilochus colubris) perched high on a snag behind the Center Pond and turned his iridescent green back to the morning sun. We saw a quick orange flash at his throat but I missed it. The Stokes Guide to Bird Behavior (Vol. I) indicates that males’ throats look brown or black if the light doesn’t hit their necks just right. When I returned on a late afternoon, there he was on the same snag – but this time the afternoon sun caught the edge of his throat which shone gold rather than ruby red. He’s not the most glamorous hummer, but I’m glad I got to see a bit of his gleam.

This male hummingbird’s bright throat only shone for a second in the morning sun, so I settled for the light in his eye and his iridescent green back.
The same male hummer’s throat shone gold in the late afternoon sun.

Near the Center Pond, the birders also discovered the nest of a Rose-breasted Grosbeak (Pheucticus ludovicianus) – with the male sitting calmly, tending the eggs or nestlings. Occasionally, he even sang his lovely tune as he waited patiently. I’d read in the Stokes Guides that male Grosbeaks sometime take on this responsibility, but I’d never seen it. On three separate visits, the male was the only one on this nest – though the female may have relieved him at other times. So, Happy Father’s Day to this dedicated Grosbeak dad!

In a willow to the right of the deck in the Center Pond is a beautiful nest.  It’s cleverly attached between two vertical branches about 20 feet up, ingeniously woven and quite large – maybe 9 inches long. During my first 3 visits, only the female’s black tail cocked behind her was visible from the observation deck. Finally one afternoon, I waded into the grass at the pond’s edge and  caught sight of her hindquarters as she fed her young. And then, I saw a fledgling’s head just above the edge of the nest. Ah, this nest was constructed by a female Red-winged Blackbird (Agelaius phoeniceus) – a somewhat eccentric one since Red-wings normally build close to the water and weave their nests among cat-tails or reeds. She’s quite an architect! The location of this elaborate nest makes it nearly invisible and unreachable by predators. Clever mama Red-wing!

Two nests appeared high in a tree on the Walnut Lane. The barely visible, masked eye of the female Cedar Waxwing (Bombycilla cedrorum) peeked through the leaves that camouflaged the first nest spotted by the birders. Since she sat there quietly every time I visited, I’ve included a photo of a Waxwing from a previous year so you’ll  remember how elegant this conscientious mother bird truly is!

Only the masked eye of the female Cedar Waxwing shows above the edge of her cleverly hidden nest along the Walnut Lane.

Across the Walnut Lane, the birders also discovered the nest of a female Eastern Kingbird (Tyrannus tyrannus) who spent several days building her gauzy, somewhat more loosely constructed nest. She proudly stood above it a few days later as it neared completion. The female Kingbird constructs the nest and keeps the male off it until the eggs hatch. Then both parents feed the nestlings. But even during the egg phase, the male stays on a branch nearby to defend the territory for his mate and young.

Another good provider, a tiny male Yellow Warbler (Setophaga petechia) brought a bright green caterpillar to feed his nestlings or mate. In between feeding trips, he’d let loose with his proud song, “Sweet, sweet, I’m a little sweet.” Impressive dad who can bring home the bugs, singing all the while! Bet the female warbler was as impressed as I was.

An Orchard Oriole male (Icterus spurius) serenaded us from a small tree in the middle of a meadow. His long, melodious song sounded much like the third song recorded at this link.  A few Orchard Orioles seem to come to Bear Creek each year – but they migrate south by mid-July. So keep an eye out and an ear cocked soon in the meadows to the east of the Walnut Lane!

An invisible bird, high up in the tree tops, repeated its melodious warble continuously one warm morning. I’ve never seen a Warbling Vireo (Vireo gilvus); they rarely come down from the heights. But fortunately, a great photographer from the iNaturalist website, Steven Mlodinow, has seen one and generously allows others to borrow his photo. Listen for this warbler’s rich melody all summer long, but don’t be surprised if you never spot this elusive summer resident.

Little Surprises Near the Wetlands

At the northeast corner of the Center Pond, a young Painted Turtle (Chrysemys picta) hurried to cover her eggs one hot afternoon. She’s found a likely spot where Ben had cleared away invasive shrubs a couple of years ago. As you’ll see in the video below, she work really hard with her back legs to get the dirt to move. She’d no doubt have preferred sandier soil! But she was determined to see the job done!

I’ve seen Northern Leopard Frogs (Lithobates pipiens) periodically at Cranberry Lake but never one at Bear Creek. But hearing their snoring call near a wetland, I waded into tall grass and found this one, hiding among the greenery. Glad to know this beautiful frog is at Bear Creek, too.

Ben noticed an  Eastern American Toad (Anaxyrus americanus) toad on the path one afternoon when we went to look at nests.  Normally, I only see brown toads, but Wikipedia informs me that “The color and pattern is somewhat variable, especially for the females. Skin color can change depending on habitat colors, humidity, stress, and temperature…Some toads of this subspecies have a more pervasive red and deep brown color, many with red warts on their bodies.”  So this little toad is probably female and the red description  fits  her pretty well.  I wonder if the unusually hot temperatures had an effect on her appearance?  Hard to tell.

Amazing Insects: A Butterfly I’ve Missed for Years, Favorite Dragonflies and the Skills of Tiny Pollinators

Next year, I’ll be looking for the boldly patterned Baltimore Checkerspot butterflies (Euphydryas phaeton) on June 11 or 12. I’ve only seen them on those two dates, 6 years apart! This year, four of them fluttered at a spot in the trail where water runs under the path – a place I’ve often seen other small butterflies feeding on minerals left by the water. Later in the summer, watch for the communal caterpillar webs of these small butterflies (about 2.5 inches) on the host wildflower Turtlehead (Chelone glabra) where these butterflies lay their eggs during the summer and where the caterpillars first feed.

Interestingly, in the fall, Baltimore Checkerspot caterpillars wrap themselves in leaf litter, overwinter and finish developing in the spring. This seems to be a big year for them – so keep an eye out if you see a small, dark butterfly at your feet.

The Baltimore Checkerspot overwinters as a caterpillar.

Different species of dragonflies seem to appear each week to dance among the budding wildflowers and over the pond. The dramatic, yet quite common Twelve-spotted Skimmer (Libellula pulchella) did indeed skim over the tops of grasses in the Eastern Meadow this week. Dragonflies often land, fly, and then come back to the same dry stalk – so if you miss one in your binoculars the first time, wait a moment and you’ll probably see it in the same place again!

A bright green Eastern Pondhawk (Erythemis simplicicollis) dragonfly clung to a grass stem on the western slope. If it’s a male, it will gradually turn blue over the summer. If a female, it will remain green. Probably this one is newly emerged since it’s hunting in a meadow. When it’s ready to mate, it will rendezvous with others  at the Center Pond.

This Eastern Pondhawk is still in the meadow but will go to the pond when it’s time to mate.

A small Dot-tailed Whiteface (Leucorrhinia intacta) dragonfly posed for a face-on selfie at the Playground Pond before continuing its quest to consume as many mosquitoes, flies and other small insects as possible before the day is out. Love its cartoon-like face and the one yellow dot on its tail that give it its name.

Easy to see why this is called a Dot-tailed Whiteface dragonfly, eh?

 

 

 

 

 

 

 

 

 

 

Pollinators are busy all over the park, feeding and carrying the pollen that will bring us next year’s blooms. This may look like a European Honey Bee (Apis mellifera) but Honey Bees are fuzzy all over and this one just isn’t. So it’s more likely to be a Dronefly (Eristalis tenax), a type of Hoverfly (family Syrphidae), which uses its pattern, slight fuzziness and loud hum to mimic male Honey Bees as a way of protecting against predators. Droneflies cannot sting, but a passing dragonfly probably doesn’t take a chance!

This dronefly (a kind of hoverfly) mimicks a bee’s appearance and hum for protection.

I noticed what looked at first like a tiny wasp on this umbel of a native Nannyberry bush (Viburnum lentago) near the Center Pond. But after a bit of research in Pollinators of Native Plants by Heather Holm, I’m going to guess it’s a female Leaf-cutter Bee (family Megachilidae). It has a wasp-y pattern and shape and it’s collecting pollen on its abdomen and on the top of its back leg (look at those jodhpurs!). Leaf-cutters cut small, neat circles out of leaves, hence the name. They then roll up a single fertilized egg and a chunk of pollen in each circle, forming a solitary, cigar-shaped nest which is placed in a hole in the soil, wood or other structures. Such an unusual nest!

Bring a Friend – or Friends! – to Visit Your Favorite Park

Oakland Township Natural Areas manager Ben VanderWeide leads a group of birders at Cranberry Lake Park

I’ve always loved walking alone in the township parks. I can listen to birdsong, stop to look at something tiny like the Little Wood Satyr butterfly below, or enjoy the fresh scents of wood, greenery, the earth after a rain in silence. Solitary walks are contemplative.

But this particular blog testifies to the special pleasures of hiking with interested friends and family. First of all, they just bring more eyes! I’m always seeing things with the birders or with my husband, that I’d never have noticed with just my two eyes (in this case, the owl, the hummer, the oriole, the male grosbeak in his nest and more). But also their curiosity piques mine. They bring specialized interests and knowledge. They often patiently help me find the bird hiding in a leafy tree (“The center trunk at about 2 o’clock…). It’s a different kind of delight to walk with nature-noticing friends. So if all of this nature stuff intrigues you, take some nature-lovers with you on your next walk. Or consider joining our friendly birding group on Wednesday mornings year ’round. We’d love to have you join us! (The schedule is under “Events” at the top of the home page.)

Bear Creek Nature Park: Little Spring Dramas Everywhere You Look

Native choke berry shrubs (Prunus virginiana) burst with blooms to attract  pollinators before the trees leaf out.
Blog and photos by Cam Mannino

Late April and early May are full of dramas. Birds hassle each other over territories. Some turn their brightest feathers into the sunlight or sing elaborately constructed songs  to impress the ladies. Snapping turtles roil the waters of the marsh as they twist and turn with their partners, butting heads and biting as they perform their mating dance. Late spring wildflowers and smaller trees hurry to show their best blooms to attract pollinators before bigger trees cloak them in shade. It’s a bustling, slightly crazy season – and isn’t it great?

 

Migrating Summer Birds Busy Courting, Hassling and Scouting for Nests

Down at the Center Pond one cool spring morning, the birding group watched a Green Heron (Butorides virescens) warming itself on a log at one end of the pond.  Its neck wasn’t stretched over the water, so it wasn’t seriously fishing; it just sat there peaceably. Gradually,  a pair of passive-aggressive Canada Geese (Branta canadensis) noticed its presence and decided, evidently, that they wanted the pond to themselves. They cruised slowly up to the heron until one of them was nearly beak to beak with it. The heron just sat. They joined forces and approached together. The heron just sat. Finally, one goose climbed onto the heron’s log, while the other positioned itself directly in front of the hapless heron. It sat for another minute and then finally acquiesced, fluttering off to the muddy shore nearby. Conflict successfully avoided, it probably found plenty of snails, insects and amphibians to eat while waiting for the geese to depart.

Sometimes the ongoing drama is a little less obvious.  Rose-breasted Grosbeaks (Pheucticus ludovicianus) are plentiful in Bear Creek this year. One morning a male turned his bright pink breast patch to the sun and trilled his elaborate spring song repeatedly for his more modestly dressed mate. (If you hear a fancy version of the robin’s song, there’s likely to be a male grosbeak nearby.)

A female Rose-breasted Grosbeak listens to the male’s operatic song.

But nearby, there’s a careful observer. The female Brown-headed Cowbird (Molothrus ater) is high in a tree listening, too.

A female Cowbird high in a tree watching to see if a likely bird builds a nest in which she can lay her eggs. The Grosbeak’s perhaps?

She’s watching for a likely nest in which to lay her eggs. Maybe she’s hoping  the grosbeaks will be the ones to nurture and raise her young. Fortunately, the grosbeaks aren’t great prospects. They’re big enough to push the eggs out of the nest – if they notice them. Some birds do and some don’t. The drama hasn’t reached Act II.

In the small meadow west of the pond, a male Gray Catbird (Dumetella carolinensis) spent the morning stringing together short phrases – whistles, tweets, trills and  imitations of birds, frogs, even occasionally machinery!  His complicated song can go on for minutes without repetition! This male combined song with ruffling his feathers and chasing after the female who was playing hard-to-get. She’d stop to listen, fly off and then dart toward him. He’d pursue her, fluff his feathers again and sing something new. And on they went at the forest edge and among the meadow’s small trees and shrubs.

The male catbird taking a quick pause before ruffling his feathers and breaking into elaborate song.

Some migrators arrive in busy flocks, just stopping over for a short while to refuel before flying north. This week, a flock of 6 or 7 White-Crowned Sparrows (Zonotrichia leucophrys) rode in on a south wind during the night and spent the morning gobbling whatever they could find at the edge of the trails. Such a handsome little sparrow with its striped crown!

A small flock of White-Crowned Sparrows stopped to forage at Bear Creek on their way to cooler nesting grounds farther north.

Some birds fly in for just a short time to breed and then return to southern climes. This Orchard Oriole (Icterus spurius), the smallest of the orioles, flitted quickly among the branches, nibbling on sweet leaf buds for a little quick energy. Even if he finds his yellow-green mate and nests, he’ll likely be gone by mid-July – back to his favorite haunts in Central America.

The smaller, russet-colored Orchard Oriole may nest here, but will leave by mid-July for Central America where he spends the rest of the year.

High overhead, a pair of Sandhill Cranes croaked their wild cry, sounding and looking like two prehistoric pterodactyls with their giant wings. (Click on photos to enlarge; hover cursor for captions.)

The warblers, the tiniest of migrants, have begun to arrive.  A week ago a fellow birder helped me spot two species – the Yellow-rumped Warbler (Setophaga coronata) and the Yellow Warbler (Setophaga petechia) – and, we think, a Ruby-crowned Kinglet (Regulus calendula.) I didn’t manage to take any decent photos since some ate high in the tree tops and others hopped madly from limb to limb nibbling on leaf buds. So here are three photos from last year just to jog your memory.

In the western meadow, an Eastern Kingbird (Tyrannus tyrannus) paused on a stalk. Kingbirds have a crown of red, orange or yellow feathers under that black cap, but they only show when they’re attacking a predator. I’ve never seen them. According to Cornell lab, this solitary, feisty bird changes his lifestyle in the winter, traveling in flocks all along the Amazon and eating fruit instead of Michigan insects. A favorite photo below from a few years ago shows his crown just slightly raised and his red gaping mouth.  Maybe he’s feeling just a wee bit aggressive?

The Eastern Kingbird has colored feathers under that black cap that show when he’s aggressive toward a predator.

Drama in the Wetlands as Well

Over in the marsh, a very small Snapping Turtle (Chelydra serpentina) and a MUCH larger one roiled the water at the far end of the marsh. The difference in their neck lengths will help you determine their relative size in the photos.

I assume the smaller one was the male as he attempted to mount the back of the female’s huge shell at one point.   Snappers generally do a lot of face biting when they mate, sometimes injuring each other. The photo below may look like a kiss but it’s more likely that the small turtle on the left is approaching to bite some indeterminable body part of the larger on the right. It didn’t look as though things worked out too well for either of them. After some rolling and tumbling in the marsh, the smaller swam off and the larger floated calmly in the distance.

What looks like a turtle kiss may actually be a bite that the smaller turtle (left) is giving the larger as part of the attempted mating process.

Blue-spotted Salamanders ((Ambystoma laterale) reproduce in a less excited manner. According to the Michigan Department of Natural Resources, salamanders emerge from their burrows on the night of the first snow-melting rain (now that would be dramatic to witness!) and go to the nearest vernal pool After a little nudging and hugging, the male deposits a sperm-topped cone of jelly on the ground in front of the female. She takes it in to fertilize her eggs, which are laid in the water in the next day or so. By mid-summer, the hatched tadpole-like larvae develop lungs instead of gills and absorb their tail fins, taking adult form.  Red-backed Salamanders (Plethodon cinereus) lay their eggs in burrows and their young hatch as miniature adults. Here are some salamander eggs and a salamander larvae/tadpole that the monitoring team found in a pool last year, plus three different species of juvenile salamanders under some wood in the park two weeks or so ago.

In the Woods, Not Much Drama, but Burgeoning Life

Again this year, a raccoon is inhabiting the giant hole in the Oak-Hickory forest. Other years this has meant a passel of playful kits by the end of May. I saw nothing until I stepped into the crunchy leaves at the trail’s edge and this curious face popped up at the edge of hole.

A raccoon has found the hole that is often used by females to bear and raise their young. We’ll know by the end of May.

The Red Admiral Butterfly (Vanessa atalanta), a migrating insect who probably overwintered in southern Texas, arrived at the wood’s edge a couple of weeks ago. According to Wikipedia, Red Admirals usually have two broods here between May and October.

The Red Admiral overwinters in Texas but comes here to have 2 broods between May and October.

Under the growing canopy of bright new leaves, a carpet of Wild Geranium (Geranium maculatum) is blooming. In the blossom below, a tiny bee from the Halictadae family has curled up to feed on flower nectar. These tiny bees are commonly known as “sweat bees” because they like to lick salt from us humans (luckily, their sting is very minor). This bee’s bright metallic green may mean it’s an Augochlora Sweat Bee (Augochlora pura), solitary bees who don’t live socially in hives. If you know your Michigan bees, please feel free to correct me.

 The Little Dramas Keep Life Coming

Delicate early spring blossoms of the native Serviceberry (Amelanchier interior) near the eastern end of the Center Pond

The dramas of spring creatures mean life continues. The best singer, the most beautiful feathers, the best provider of a good territory get chosen and a new generation begins. Fortunately, the temporary territorial disputes of birds don’t usually result in death or destruction. One bird moves on to new territory and in many cases, joins his former competitor in a fall flock which ends up feeding calmly together on winter feeding grounds. Nature knows that both low level conflict and general cooperation keep life going, even improving, generation by generation.  Maybe we humans should take a lesson from them?

This Week at Bear Creek: Wildflowers Galore, a Damsel in No Distress, New Birds and Very Small Frogs

This week the native wildflowers are glorious!  You can start admiring them right in the parking lot!  Since Ben and his crew burned the center circle of the driveway, native wildflowers are sprouting there like crazy! And the native beds on either side of the shed are full of blooms.

I’ve enjoyed learning the common names of wildflowers in the last few years.  Knowing names starts a relationship with a plant in the same way that knowing a person’s name makes them more than a casual acquaintance.

This striking,  deep violet-blue native plant with long graceful leaves has an unfortunate name,  Spiderwort (Tradescantia ohiensis).   (People who came up with common names seemingly had no poetry in their souls and  must have thought it cured spider bites).  Look at this beauty up close!

Spiderwort, a native wildflower,  looks wonderfully exotic but has a pedestrian name which may refer to an earlier belief that it was a cure for spider bite.

There’s also this golden flower that I’d never seen in the circle until this year after the burn.  I love the buttery yellow glow and scalloped petals of Sand Coreopsis (Coreopsis lanceolata) and so does what looks like a hover fly  whose abdomen is smeared yellow with its pollen.

coreopsis w hover fly2
I believe that’s a hover fly with his abdomen and legs smeared yellow with pollen on this native Sand Coreopsis right in the center of the driveway at Bear Creek.

In the park and in the circle is a happy yellow flower called Golden Alexanders (Zizia aurea). It does well after a burn because our part of Michigan used to be prairie. Prairie and other grasslands across North America have burned regularly for thousands of years. Fires were either intentionally set by Native Americans or lit naturally by lightning.  This native plant is adapted to fire and loves sandy soil and sun.

 And look at the burgeoning overflow of beautiful Canada Anemone (Anemone canadensis) in the native flowerbed north of the shed!  Native plants can take a few years to really get going but once they do it is worth the effort. And clearly this was the year for these beauties.  Talk about ground cover!

While you’re admiring them, enjoy the many Hebard’s Green-legged Grasshopper nymphs (Melanoplus eurycercus) springing from leaf to leaf among the Anemone.  By August, they’ll have molted into much bigger grasshoppers.

Ben’s reported seeing some great birds in Bear Creek, some I have yet to see.  Cornell Ornithology Lab’s allaboutbirds.org wonderfully describes the beautiful deep blue Indigo Bunting (Passerina cyanea) as being “like a scrap of sky with wings. ”  This amazing small bird migrates at night, navigating by a single star.  The young learn their cheerful song from nearby males in their “song neighborhood” and these local songs can last for 20 years passed on by successive generations. They are tricky to photograph (as you’ll see below!) as they sing high in the treetops near woods in shrubby areas – like the northern end of the steep sloping path on the Southwest side of the park or in the center of the big loop at the northern part of the park.

Ben saw the smaller, darker Orchard Oriole (Icterus spurius) in Bear Creek.  I have a photo of the female at Bear Creek a couple of years ago but the only decent photo of the male I have was taken at our oriole feeder.  They’re here only a short time, arriving late and leaving early, sometimes as early as mid-July, for their winter home in Central America. So look for them soon before they are gone!

The male orchard oriole is smaller and more russet than the Baltimore Oriole which is more orange.
female orchard oriole
The female Orchard Oriole, like the female Baltimore Oriole,  is yellow rather than orange like its mate.

Ben also saw a bird at Bear Creek last week that I’ve never seen there – but I did hear one today at Marsh View Park.  The iris in the eye of the Red-Eyed Vireo (Vireo olivaceus) turns red when it matures so don’t be surprised when you click the link below and see a gray and white bird!  The amazing feature of these Vireos is that the male whistles his brief song incessantly from morning ’til night, sometimes repeating a song over 20,000 times in a day! Once you recognize it , you’ll know you’ve heard it in the woods for years.  So click here and then go down the page on the left to the “typical song.”

Those Green Frog tadpoles I mentioned last week are now very young frogs!  Look for them roiling the water in the pond near the playground.  They are still very small, their legs are not fully developed and some of them, as you’ll see in the photo below, still have stubs of tadpole tails that they haven’t yet absorbed into their bodies.  Like other creatures born in huge numbers, frogs serve as fast food for a lot of other species. Without lots of little frogs for nutrition, the predators that depend on them for food will be hungry. That’s one reason the declining numbers of amphibians is a concern in native habitats.

These young frogs are not fully developed yet and in fact the bottom one is still absorbing his tadpole tail into his body.

Watch for the Snapping Turtle too.  At the playground pond last Sunday, we spotted him  as a large oval patch of Duckweed moving steadily just under the surface of the water.  I imagine that he was using some young frogs as a quick snack.  Here’s a photo of one last year basking after a trip through the duckweed.

A sleepy little Gray Tree Frog  (Hyla versicolor), strictly nocturnal,  snoozed Sunday on one of the platform supports. Once grown it will generally stay high in the trees except when it comes down to breed. I imagine that’s why its skin looks so much like tree bark – good camouflage!

And what about those damsels in no distress?  Well I was referring, of course, to damselflies, those slim, elegant cousins of the dragonflies in the order Odonata.  Sunday this one flashed like neon blue morse code as it rested with its wings folded near the playground pond.  I’m guessing that it’s a Marsh Bluet ((Enallagma ebrium)) but again, don’t quote me.  Bluets are a big group of dragonflies and they all have only minor differences.

This damselfly, perhaps a Marsh Bluet, shines neon blue in the sunlight.

One of the dragonflies at the playground pond is almost comic in appearance!  I swear it has a kind of Mickey Mouse face!  Its precise but unimaginative name is the Dot-tailed Whiteface (Leucorrhinia intacta)and you can’t miss them! They’ll even accompany you down the boardwalk.

QUICK REVIEW:  New sightings of  species mentioned in earlier “This Weeks”

Evidently, the Green Heron is still fishing down at the Center Pond.  If you admire patience, speed and accuracy, this bird has it all.

Wow!  Have a look at one of the branches hanging low over the pond by the playground.  I hobbled over there with my walker last week and we spotted  the long narrow tube of an Baltimore Oriole nest among the branches.  Watch quietly and you’ll see the orange tail feathers of the female oriole as she goes head down into that tube to feed her nestlings.  She and the more colorful male foray out repeatedly gathering food, too and it’s such a close viewing spot, easily accessible for children.  Here’s a quick reminder of the nest shape, though the one at the playground pond is more hidden in the leaves.  (When I replace the camera I dunked in the marsh, I’ll try for a photo of the current one.)

A nest much like this one but hidden in leaves hanging over the playground pond contains Baltimore Oriole nestlings – with their mama head down feeding them.

And last week I featured the male Common Whitetail Dragonfly (Plathemis lydia).  Here’s a female Whitetail  who has settled on the rocks at the east end of the driveway circle.  She’s been there twice in the last week.  She lacks his bluish-white tail but has a lovely pattern down the edge of her rich brown abdomen.

Bee balm/Wild Bergamot (Monarda fistulosa) will be blooming shortly in the native bed south of the shed, the circle in the driveway and out behind the center pond.  Only the leaves are out now but when they bloom, their lavender flowers will look a little like a frizzy hair dayBelieved to have medicinal properties (hence the name), native bee balm is indeed a balm to bees and butterflies who feed on it.

Native Bee Balm/Wild Bergamot is a good source of food for bees and butterflies.

The leaves of our native Common Milkweed (Asclepias syriaca) (which unfortunately is not as common as it needs to be) are sprouting everywhere in the park, including the driveway circle.    Before long, the leaves sprouting now will create fun landscapes like this:

Milkweed leaves are sprouting around the park so their pompom-like flower balls should be showing in a few weeks.

One reason the number of Monarch Butterflies (Danaus plexippus) is dangerously low is that we don’t have enough Common Milkweed in many places.  Unfortunately, some nurseries are selling a non-native variety which can’t act as a host plant for the Monarch’s caterpillars.  And as meadows become lawns, more of our native Milkweed disappears.  We’ll explore a bit more about milkweed later in the season.

Summer is blooming: Birds feed their young, wildflowers unfold, dragonflies and damselflies dart above the ponds.  I hope you’ll find time this week to explore and relax in Bear Creek Nature Park.
