The forecast predicted the snowfall to begin at 9, when the hike starts. It wasn’t yet snowing when I arrived a few minutes before. The sky, though overcast, brightened the brown forest floor. The past few chilly days and freezing nights finally forced many of the oaks and maples to lose their lingering leaves.

The birds – usual winter flock species – scurried about the canopy for last-minute food before the snow and called in constant communication: titmice, chickadees, white-breasted nuthatches, white-throated sparrows, juncos, a red-bellied woodpecker, a hairy woodpecker, a lone American crow. I thought I saw and heard a kinglet, but the chickadee’s incredibly quick movement tricked me. But as luck had it, the moment I got my binoculars on the chickadee, I spotted a nearby Brown Creeper gradually climbing the trunk. I’d actually heard the creeper’s tinny, high-pitched call.

The time read five past nine. Mike was unusually late. No one else showed. Was the hike was somehow canceled without my knowing? …Or was today even Second Saturday? I took the creeper as a sign of good birding to come. I went ahead.

Halfway to the kiosk intersection, I heard a loud rapping from somewhere within the locust grove. Time to play Find that woodpecker! I expected to spend quite a bit of time hunting for the noise-maker. Not for long this occasion… A Pileated Woodpecker took off and flew towards the parking lot. It maniacally called the entire way, prompting the jays to shout in slight hysterics.

I stood at the intersection to listen for other birds. I heard voices. A look through my bins down the trail revealed they belonged to Mike and another person. When they caught up, Mike explained he was late because he had to deal with work issues. Karen, both a birder and a hiker, would be the only other joining us for the hike. She hikes around Brinton Brook once a week, though she wished she could make it to the Second Saturday hikes more often.

Beyond conversation, I only heard a few white-throats at the meadow. I encountered more – plus a song sparrow – foraging in the cattails at the western end of the pond. When I reached well away from the cattails, the white-throats migrated to the shrubs at the edge of the path, leaving the song sparrow to its own. Juncos twittered in the canopy.

A thin layer of ice coated this end of the pond. Mike thought we wouldn’t see ducks. But when we reached sight of the other end, quite a few waterfowl were foraging: Four Green-winged Teal (all males, with lovely auburn and green faces), eight Mallards, and a dozen Canada Geese. Though they segregated themselves in groups of their own species, they all kept close to one another. The ducks moved to the back the closer we approached. The geese didn’t mind us that much, of course.

Meanwhile, nearly a dozen goldfinches fed on the black birch seeds above our heads. A couple whitehatches “yanked” incessantly. A Carolina wren trilled. As I watched the ducks, a kinglet bounced from one reed bunch to another over the pond, barely giving me time to notice that it was Gold-crowned.

Snow began to fall when we ventured out to the power-lines, starting off as flurries then quickly becoming heavier. One could hear the flake bunches practically hitting the ground and the vegetation. The power-line wires usually buzz, but today they sizzled. Snowfall filled in bird silence. I heard only sparse calls from a few birds: a second flicker, a second song sparrow, and a some more white-throats.

Now that snow was falling quite a bit in the woods, the birds in the sanctuary also quieted down. So much so that I heard maybe a couple titmice and white-throats at most until we reached the parking lot again. We even took the longer route again, hiking the new white trail the golf course owners created. We enjoyed walking through the first-of-season snow. Karen took the opportunity to finish talking about her Purple Martin housing problem. She’d just put up the housing – a gift from a friend – this past breeding system. But an adamant flock of House Sparrows kept trying to nest in the gourds, even after she repeatedly climbed to throw away the nesting material (the gourds are fifteen feet above the ground). Eventually, the “little fucks” took revenge by chewing on her fencing and garden plants. She was thinking of donating the martin housing to Croton Point and purchasing a house sparrow trap.

Mike said to watch out for the juncos when we reached the stream near trail’s end. Alas, there were none.

We came back to the same birds I observed before the actual hike. As Mike and Karen talked, I thought I heard a Gold-crowned Kinglet. I kept my ears open for the high-pitched see-see-see call. Instead, I heard a Yellow-bellied Sapsucker’s mewing. It mewed for a good minute. I thought I saw one right after the Pileated sighting. I’d taken note of the facial markings, but the locust branches obscured the sapsucker so much I eventually lost sight of it. I was glad to hear it mew at the end of the hike.

All in all, I observed 22 species. A decent number for this time of year at Brinton Brook with a few good winter birds. Always nice to have a brown creeper – my favorite bird! You can view the eBird list here.

Sadly, this month’s hike is my last Second Saturday. I will be moving away after the New Year, before January’s hike. These three-and-a-half years were filled with fun and educational experiences. Thank you for everything, Mike!

I’m thinking of re-locating my own Second Saturdays to Sapsucker Woods.

Brinton Brook Hike, Report 11-2017

I took the day off from work to attend the Second Saturday hike! It almost felt strange to be a part of a group going around Brinton Brook, and I certainly missed it. This month’s group consisted of no strangers: hiker leader Mike, regular/caretaker Rudy, Saw Mill River Audubon President Val Lyle and her partner Alan, and Mike and Yuan who are regulars of SMRA’s Monday morning walks. Once again, our hike was dominantly a birding hike.

The temperature late this week took a dive to below freezing, in the mid-20s. With a little wind, we had a nicely brisk hike. Most trees – sugar maple, red maple, tulip, sycamore, sassafras, etc – lost their leaves, which covered the trails in several layers. Only White Oak and American Beech still kept their leaves.

We didn’t encounter much bird activity until the black locust grove at the kiosk. I heard a few House Finches. Some of got on a Red-bellied Woodpecker and one Hairy Woodpecker, though I’m sure I heard at least three Hairies in the vicinity.

The meadow was quiet. Rudy pointed out a tree in which he saw a lot of birds flying around in (possibly eating caterpillars that had just hatched) back during July’s hike. In the middle of his story, we suddenly heard something took off from behind us. All of us turned around in time for us to see a medium-sized bird rushing away to the trees, wings whistling loudly.

American Woodcock! we exclaimed simultaneously. We had a good laugh after being startled. None of us noticed it was only a few feet away from us.

“We almost stepped on it,” said Val. She and I were surprised to see one so late in the year.

“That means the meadow is doing really well,” Mike remarked. SMRA maintains the meadow habitat by mowing it once a year and ensuring a healthy biodiversity through growing native plants, such as goldenrod and butterfly weed.

Much later, when I submitted my list to eBird, I saw that this woodcock is the first sighted at Brinton Brook ever.

We took a brief rest at the western end of the pond, where the donated bench is located. When I was here last month, the pond was mostly wetland. A lot of rain had fallen over the past couple weeks, and the pond was a pond once again. A late Eastern Phoebe flycatched in the trees in front of us. At the other end, we saw a small flock of Mallards. I noticed that two of the ducks looked peculiarly small.

We walked the trail quietly. The ducks moved a bit to distance themselves from us. At a clearer spot with better lighting, we began to make out that this duck flock was more diverse that we first realized. First, we noticed that there was one American Black Duck. Second, I confirmed my guess that the very small ducks were Green-winged teal, last sighted this April during the Second Saturday Hike, overall the third time sighted in the sanctuary.

Third, to my great surprise, I then noticed one duck a little larger than the mallards that had a certain brown head with a certain white face stripe and white neck: Northern Pintail. This male didn’t have the eponymous long tail – it was quite short. That tripped me up. But I would know the head pattern any day. Once again, I observed first bird for Brinton Brook! I couldn’t contain my excitement at the idea of seeing a pintail here. These are rare in Westchester to begin with.

When we arrived at the blue trail’s beginning, Rudy said that he had been hearing a Barred Owl somewhere around the Pond Loop. I asked Val to play some playback on her phone. Everyone started hiking up the blue while Val and I lingered. A few “who cook’s for you” rang through the mostly silent air. After half a minute, I said forget it. Shortly after, all of us heard a Carolina Wren trill closer to Mt. Airy Road, presumably provoked by the owl playback. Carolina Wrens trill out of aggressiveness over territory or warning other birds about predators (avian or feline).

The power lines were mostly quiet as well. In the beginning, I heard a call somewhere from within a the vegetation. I pished. A few American Tree Sparrows and a Field Sparrow popped up. I didn’t see them side by side, so nearly confused the Field for a Tree. Val handily compared the two species with the Sibley’s on her phone. Tree sparrows have a rusty eyeline and bicolored bill, whereas field sparrows lack an eyeline and have a bright pinkish bill. I was apparently incorrect to use the double white wingbars as helpful point of reference.

As we were looking at the sparrows, a mockingbird flew by and second mockingbird called for a few seconds. Farther up the powerlines trail, we heard a bunch a chip calls from the other side of the field: White-throated Sparrows.

We continued on the new white trail that borders the sanctuary property. Truly, it belongs to the neighboring golf course. But since it’s a route that goes to the Croton Arboretum, hikers are allowed to use this trail. The owners of the golf course bought the parcel of land at the north-eastern edge of Brinton Brook last year to build a driving range. SMRA once had the opportunity to purchase it a couple decades ago, but we couldn’t afford it. The construction finished recently. You can see a massive grass hill-wall just beyond the trees. Very fortunately, the owners and SMRA are cooperating to replenish the border with native trees and plants.

Back to the birds. We returned to having a quiet hike, save for a small flock of Dark-eyed Juncos, a couple chickadees, a White-breasted Nuthatch, and a few singing white-throats.

Reliably, activity picked up near trail’s end. Larger flocks of juncos and white-throats foraged in the brambly ravine. Our third carolina wren for the hike sang. We counted a fourth hairy woodpecker for the hike. High in the trees foraged a mixed flock: chickadees, a couple Ruby-crowned Kinglets, and a Golden-crowned Kinglet. Two Tufted Titmice fought for a little in the trees on the other side of the trail.

When I got back in the car, the temperature read 35°.

All in all, we observed 26 species. The American Woodcock and Northern Pintail were exciting birds additions to Brinton Brook’s life list. You can view the eBird list here.

Brinton Brook Hike, Report 10-2017

Last Tuesday, I felt like I was baking in the 80° temperature as I hawkwatched on Hook Mountain. This morning, I woke up to see frost on my car, and that the temperature read 37°. I had to wear a parka, gloves, and a hat (yours truly gets cold – as well as warm – easily).

As I got ready in the parking lot, besides the usual common birds, I heard White-throated Sparrows singing and calling around me. These weren’t my First-of-Season (FOS), as I heard a white-throat singing briefly near my bedroom window a few days ago.

When I reached the kiosk intersection, more white-throats were calling. Two Pileated Woodpeckers moved around a tree trunk behind the kiosk. They flew away as I walked closer. I then began observing more than the dozen white-throats: I was blasted with a migration movement. Sunlight poured through the wood, warming the locust grove. I started with 8 species at the parking lot. Including the Pileateds I added 13 on the Old Farm Road trail alone. I witnessed quite a group – an explosion of activity and chatters and calls and whisper songs. Several zippy Ruby-crowned Kinglets. One slightly less zippy Golden-crowned Kinglet  (FOS). Two Blue-headed Vireos. Two Yellow-rumped Warblers. A lone Eastern Phoebe. And a few common birds tacked along (perhaps also migrating, perhaps resident birds that stick with the migrants to find more food): chickadees, titmice, cardinals, downies, a towhee, a white-breasted nuthatch, a robin, and a song sparrow. They flitted all over, from branch to branch, tree to tree, fly-catching, fighting one another. They covered all levels of the canopy, from the shrubs to the near tops of the trees. I had to re-learn how to bring my binoculars up to particular spots because I didn’t have many chances to go birding these past couple weeks. I lost the birds a few times but shortly got the hang of it. I also kept telling myself to stick with just one bird for a little, then move on to another. The hyperactive kinglets, vireos and yellow-rumps made this difficult. Tallying to my best ability also proved difficult. I felt like a beginner again.

More than a half an hour later, the movement seemed to have passed on. I doublebacked to the yellow trail, so I would head towards the pond.

When it comes to birding in the spring and fall, one has to be mindful to distinguish if one is following the same migration pack or encountering additional numbers of the same species observed before. Today tried this ability of mine as well. Just passed the meadow, I observed both species of kinglets and blue-headed vireos again. I took a few minutes to especially watch the vireos; they were much closer, and I always delight in them since they are my favorite vireo species. (I then took another moment to consider what I meant when I wrote down “wb sp” in my notebook earlier. I completely blanked that it meant “warbler species,” which I used as a stand-in before I figured I was looking at Yellow-rumped Warblers. I was prepared for “confusing fall warblers,” but sometimes I simply need to spell out words even when I’m trying to save time writing while out in the field.)

I noticed it got quiet again. I found zero wader-birds or waterfowl at the pond, the water level of which was rather low, but not low enough for the land to become a wetland.

While walking along the pond, I came across ruby-crowned kinglets, blue-headed vireos, and yellow-rumps foraging right above my head. I decided against increasing the numbers – I must have been following the flock. However, I was certain that I did see four yellow-rumps at once. They were drinking at the edge of the pond. A few kinglets joined them, and a vireo was bathing.

I debated completing the full pond loop this time. I ended up turning left on the blue trail as usual. The moment the power lines came into view, I saw a Red-tailed Hawk stoop across the field. Instead of venturing out to the power lines, I continued on the blue, not having done so in countless months. I wondered about other pockets of this morning’s migration movement. For the first time ever, against a backdrop of radio silence, I could hear and recognize the golden-crowned kinglet’s tinny and quiet tsee tsee tsee call – two of them. As they continued calling regularly, I happened to catch sight of a camouflaged blurb rustling among the leaf litter: a Hermit Thrush. (Second FOS) I couldn’t recall the last time I saw one at Brinton. I find these secretive, shy thrushes thrushes hard to come by so I watched it until trees hid it from my view. Not farther down the trail, I heard soft drumming to my left. I expected a Hairy or a red-bellied woodpecker, but it was another winter resident, my third FOS for the morning: an immature male Yellow-bellied Sapsucker, whose yellow and black back looked rather blurred, though his crown and throat were bright red.

Not long after, I reached the yellow trail (the blue all the way loops to another point along the yellow). A Red-shouldered Hawk called somewhere from the northwest. Unsurprisingly, I think, I may have stumbled upon the same migration group of kinglets, vireos, and yellow-rumps from before. Indeed, I was now south of the pond, they may have traveled this bit of distance from when I last saw them about fifteen minutes before (the amount of time I spent on the blue trail). I tried to get on every bird to make sure the numbers checked out, and they were similar. My ticks remained unchanged.

A little further down the trail, when the kinglets and vireo were barely out of ear shot, I began to hear a Winter Wren whisper song, a remnant of the spring song, partial in phrase, very faint in volume. So faint that the wren sounded like it was twenty or thirty feet away. In fact, I didn’t recognize that the song to belong to the winter wren initially. This wren’s musical, non-stop trill-filled song sounds so rich and usually lasts up to six seconds – a mouthful of a song for such a tiny bird. This whisper song lasted only a couple seconds, the trills sounded squished. When I started walking again, I flushed the wren from a large log that rested next to the path. I reflexively brought my hand over my chest. I didn’t move, nor wanted to. To my relief, the wren popped back up. This one was a little less secretive compared to past winter wrens I have observed. Smaller than a House Wren, the Winter Wren’s plumage is brown like a House’s, though several shades darker overall. Its tail is shorter and stubbier, sticking straight up like bangs wet with gel. The wren hopped along the log, occasionally singing its whisper song while delicately pecking for insects. Very slowly, trying not to disturb it again, I grasped at my binoculars and brought them up. I did scare it again and it dropped down. It appeared shortly after, hopping onto another log to forage on. Its beak moved so slightly while it sang, barely opening to let sound out.

The wren dropped down again. Delighted with a fourth FOS, I decided to move on. The second I started walking, I saw the wren fly farther away from the path. I heard its whisper song another couple times before I was finally out of earshot.

Towards the trail’s end, I encountered a few kinglets and a phoebe. I counted the kinglets but kept my phoebe at 1, in case the same phoebe I saw towards the beginning decided to hook up with other birds.

Back at the parking, to my surprise, but I suppose you don’t have to guess: more kinglets and another vireo! This time, I did add numbers to my tally. I wound up with more than a dozen ruby-crowned kinglets and three vireos altogether. A conservative estimate. Even if I did see more than two migrating groups of kinglets and vireos, I’d rather I keep my numbers low so as not to arouse suspicion from eBird.

Speaking of eBird, you can view my list here. A wonderful, fall migration-filled morning!

You may noticed that I didn’t observe any Dark-eyed Juncos. Definitely next month!

Brinton Brook Hike, Report 9-2017

Because I’m continuing my State Parks job through the fall, I had to also skip this month’s Second Saturday, which coincided with the Ramble. So I went to Brinton Brook today since last Monday I went for my spontaneous hawkwatch.

Like the previous two years, this September feels frustratingly sauna-like, as if summer is sinking its fingers into the ground before finally relinquishing its transformation into autumn. This morning, though, was overcast and relatively cool (high 60s) yet somewhat humid.

My hike was oddly quiet in regards to both sight and sound. I observed 18 species – a winter number. A warbler fallout occurred in Westchester and Rockland early last week. No warbler fallouts today. Nope, not for me. Again. Brinton did not witness fall migration altogether today.

The Blue Jays, back from summer vacation, had started to make a lot of noise again. I heard them in small groups throughout the hike, at the parking lot, the pond, the power lines field, and trail’s end. They jayed, bugled, and sounded all sorts of other nameless quirky sounds. All in all, I estimated, a dozen and a half. But where the jays didn’t call, the insects and tree frogs trilled.

As I made my way to the kiosk intersection, I saw ahead of me chipmunks fighting. A male Northern Flicker foraged in the path. A cardinal – later ID’d as female – was chasing another bird, which I presumed to be another cardinal. I crept towards the flicker, which bounced in and out of sight, so as not disturb it. About ten feet away, I put my bins on the bird. Strangely, its silhouette looked un-flicker like. My heart nearly stopped when I saw it was a Brown Thrasher. It quickly dived into the shrubs and hid. I had not seen one since July 2016, the latest eBird record at Brinton.

I pished at the kiosk. A small bird skulked around but did not reveal itself. Behind me, I flushed out the female cardinal and the thrasher.

Pond activity mostly included jays and Downy and Red-bellied Woodpeckers. I also heard a Hairy Woodpecker’s pique! call. I kept my eye out for herons and immediately noticed on the far side a Great Blue, whose blue-gray torso blob stuck out against the swampy, lily-pad laden water.

The power lines whirred over my head. I counted seven Gray Catbirds mewing along the length of the path. Two Carolina Wrens sang and trilled. An American Crow cawed in the distance. A Turkey Vulture soared. A Great Blue Heron flew overhead to the north-east. To my surprise, an Eastern Bluebird intermittently sang. Sadly, I couldn’t get a visual on it.

As for insects, I saw a few Red Admirals. And now that I have an eye for moths, I noticed a number of grass-host moths on the ground before me. I flushed them often as I stepped forward. I tried taking pictures of them, but as soon as I took only one step towards them, they would flutter farther away. Skittish things!

The clouds parted enough for the sun to shine, but the moment of that path blue sky barely lasted a minute.

IMG_2053

I turned my attention to moths again during my descent from the power lines. Besides additional jays and White-breasted Nuthatches, and my first and only chickadee, this part of the hike was quiet. I flushed the moths from the path – probably litter moths since they rested among the leaf litter. I couldn’t get on these either. They were just as skittish.

About a few minutes away from trail’s end, I saw a small bird skulk in the bushes on the side of the path. At these quick glances, I thought I had a House Wren. I pished. It revealed itself straight away. And no wonder why. A male Common Yellowthroat, with a gorgeous crisp black mask and yellow throat. (This warbler species is guaranteed to respond to pishing.) It flitted about, tail flicking, even after I stopped pishing. I left it alone when I figured it wouldn’t stop checking out the scene anytime soon.

My last additional species came from the Weinstein property: a lone robin softly cuck-ing.

You can view the eBird list here.

Brinton Brook Hike, Report 8-2017

The day began cool but gradually warmed to slightly uncomfortable, with a little humidity. Several year-round birds sang the parking lot as I readied myself for the hike: Northern Flicker, Blue Jay, Northern Cardinal, Carolina Wren, American Robin, White-breasted Nuthatch, American Crow.

I stood at the kiosk intersection for a bit. An Eastern Wood-pewee cried “pe-weeeeee!” Three Downy Woodpeckers sounded off one-two-three. Two chanting Black-capped Chickadees, singing in different keys, managed to utter one “fee-bee” phrase simultaneously, puncturing the air with brief discord.

IMG_1834

At the meadow, I heard an unfamiliar chipping note coming from a bush. I attempted to pish the bird out. Chickadees and a male cardinal gathered nearby and responded with annoyance. A Pileated Woodpecker manically called deep in the trees. I persisted for another half-minute. Finally, an immature male Indigo Bunting popped up to the tree above. His transformation to become an adult was nearly complete. Small brown spots dotted his vibrant blue.

Hardly any goldenrod grew in the meadow. Only one bush. Unfamiliar vegetation – most likely invasive species – had taken hold instead. Not many butterflied fluttered about. Maybe one Great-Spangled Fritillary and a couple Red Admirals.

At the pond, up to maybe a dozen Blue Jays – adults and immatures – called and bugled as they flew around. I didn’t see the Great Blue Heron from last month. The Red-winged Blackbirds had quieted down, save for the half-dozen immatures that flew from lily pad to lily pad. It was difficult to look for anything in the reeds on the other side of the pond since the tree branches blocked much of my view. To live up to the label “birder,” I made believe I could somehow find a bittern. Instead, not disappointingly, I caught the movement of two Eastern Phoebes flycatching and fighting. As I continued walking I heard a wet rustling behind me. A female Wood Duck flew from my side of the pond to the other. She quickly disappeared into the reeds.

My ascent to the powerlines on the blue trail was a little quiet. I heard my third pewee, more titmouse families, and still more blue jays. I startled a male flicker that was foraging on the ground. It was at this point the temperature warmed to that of a typical summer day. And it was at this point that the black flies began to harass me. I hoped they would stop once I’d the powerlines.

And they did. Sunshine forces them to hide in the shadowed woods. Other insect life was in full swing in the field. Countless bees, butterflies, and other bugs whizzed around the flower-filled vegetation, including the many goldenrod bushes. Cicadas – which I’d been hearing since I got out of the car – screamed at their loudest potential from all directions.

The first bird I spotted was a phoebe perched high in a dead tree on the edge of the sanctuary. To the west, towards Bear Mountain, a lone Turkey Vulture soared and two unseen young Red-tailed Hawks begged for food. A few Gray Catbirds meowed. A small bird zipped to a bush way behind me: a Prairie Warbler, black facial markings so faint that I wondered if it were a young one or an adult receding to fall plumage.

Green frogs hung around in the same pools where I’d scared the turtles last month. They dived into the mud at my approach. A couple of them, though, floated like this:

Ahead, a towhee slurred its call so that it sounded like “twEEEE!” instead of “tow-WEEEE!”. A female Orchard Oriole perched atop a bush, then disappeared shortly. I heard another unfamiliar chipping coming from two different small trees. The chipping, identical in sound, hinted that it belonged to two birds of the same species. I managed to get a glimpse of one of them, a female American Redstart. Since I didn’t get on the other bird, I could only guess as much that it was simply another redstart.

As I rounded the corner to the path that would lead me back into the sanctuary, I saw an orange flash. Baltimore Oriole. I tried coaxing it from the reeds with no luck.

No sooner than I re-entered the woods the black flies swarmed around my head again. I walked with my hands poised over my ears. I was swatting them every four seconds. The descent was very quiet, save for a jay calling. Disregarding bird presence, the woods actually weren’t at all quiet. Cicadas buzzed and buzzed and buzzed. I realized that there was no reason to remain patient for the birds if there were no birds to observe, so I jogged down the white and red trails to escape the black flies. Magically, I didn’t have to deal with them once I got to the yellow trail.

Now that I was nearing the end (or the beginning), I started hearing more birds. Nothing new except for a perpetual Red-eyed Vireo. I stopped at the patch where the hardy kiwi was eradicated. Behind it, perhaps fifty feet away, mid-canopy, I noticed small bird movement – a different bird. I only got a couple glimpses of it before it vanished, but that was enough for me to ID it as a Canada Warbler. Besides the soft gray back and bright yellow breast, it had the diagnostic apparent white-eye rings and a very faint necklace. I can never get enough of Canada Warblers. Their appearances are always so fleeting.

IMG_1849

I have no clue what this could be but it is very interesting. I spooked some of the insects that were chilling on top of the round things. © S.G. Hansen

I lingered at trail’s end for a while. That jogging got me ahead of time. It turned out that the timing was just right. I happily observed three excellent additional species for the list. A Ruby-throated Hummingbird rocketed in and out of view, green back shimmering brilliantly. A female Scarlet Tanager foraged mid-canopy. A male Black-and-white Warbler crept along the trees’ branches. I also watched a female and an immature male Baltimore Oriole forage, a scruffy looking Carolina Wren climbing a rotted snag, and a pewee flycatch and use the same snag as a perch.

A quick check at the Weinstein pond only yielded a Mourning Dove – the first and only for the hike – on the lawn.

I observed 33 species. I didn’t exactly experience the summer doldrums. Granted, not as many songbirds sang because this isn’t spring migration. Certain birds – besides the Red-eyed Vireo – are still vocal in the morning even during the time of year I thought they would feel like they would no longer have to sing. But I am merely going by one isolated location. Another surprise is the lack of American Goldfinch. I only heard two during my hike. Since they breed in August, I expected to observe a few more than that.

Check out the eBird list!

Brinton Brook Hike, Report 7-2017

I arrived at 8:40AM. The air was humid yet again, although the temperature was relatively cool (mid-70s). Rain had fallen the night before. Steam was rising from the driveway. The earth was damp. A breeze shook water off the trees. I listened to the robins scold, a wood thrush sing, a flicker and a pewee called, and a small group of young titmice buzz.

A Red-spotted Purple butterfly landed on the gravel behind my car. Although I’m less knowledgeable about insects, I’ve learned a few names from Mike over the past couple years. I would keep my eyes on the butterflies, moths, and dragonflies as well as the birds during this hike. As if they knew July 1 had passed, the insects climbed so high in numbers it’s become impossible to turn every angle and not see delicate wings flutter.

I heard a male Indigo Bunting sing at the kiosk intersection. I tried finding him, but his song bounced around the trees so well that he remained hidden. I pressed along to the field, where another bunting was singing at the top of a tree behind the grasses. I couldn’t figure out which was the parent of the immature bunting I saw last month. I don’t think immatures grow up so fast, although Indigo Buntings can have up to two broods per year, and it maybe that another male found good territory adjacent to the first.

I lingered for a few minutes. A couple of Great Spangled Fritillary butterflies fed on the two flowering milkweed bushes. A few cabbage whites and gypsy moths flickered around aimlessly. While trying to get more looks at this second male bunting, I noticed movement in a nearby, shorter tree. A female Scarlet Tanager (colored dull yellow) and a young Blue-gray Gnatcatcher forage so swiftly that they disappeared further into the trees after only ten seconds.

At the pond, I immediately spotted the Great Blue Heron that my friend Christine (also a Saw Mill River Audubon board of director) saw during the Second Saturday hike a couple days ago. It stood very still at the southwestern corner. Its chest was stripey, indicating it was an immature.

Lily pads almost completely covered the water. Numerous dragonflies whizzed above the water (nameless, as they were too far away and too small for me to see clearly). Red-winged Blackbirds and Common Grackles called from all around. A young Downy Woodpecker – plumage ruffled and imperfect – loudly cried. A pair of Carolina Wrens engaged in spat: one trilled and the other chattered. I flushed a dozen robins as I further ambled along the pond.

As I started hiking up the blue trail to the powerlines, I encountered two different groups of young titmice. A Scarlet Tanager call repeatedly: Chik-burr. A Blue-headed Vireo languidly sang.

A Blue Jay landed on a sapling next to the trail, and then it flew out of sight shortly after. I thought I heard it poorly imitating a Red-tailed Hawk. But when the calling continued and a grey squirrel started scolding, I knew to look for the Real McCoy. (I hear jays imitating Red-tails more often that I hear the Red-tails themselves. Sometimes the jays sound impeccable, but most of the time they sound like Blue Jays imitating Red-tailed Hawks). It was somewhere along the edge of the forest. When I moved a bit off the trail to get a sight of it, the hawk flew away.

At the top of hill, I flushed even more robins. A Field Sparrow and a House Wren sang. I heard a towhee utter Drink your tea repeatedly from the powerlines. The rhythm if this call was different from last month’s towhee. The “Drink your” sounded like eighth notes rather than sixteenth notes.

Just after I ventured out to the powerlines, four immature Red-winged Blackbirds flocked to a bush and called and called, either curious or furious about my presence. Either way, they took off when I continued walking.

I felt slightly hotter now that I was under the sun. Not as bad as last month, but still quite bright. I heard a third Indigo Bunting, two more towhees, a second House Wren, and a mockingbird sing up ahead. Many nameless small butterflies or moths fluttered or zipped around. Bumblees, honeybees, another fritillary, and one Eastern Tiger Swallowtail drank nectar from the milkweed, more widespread here, pictured below.

I unintentionally flushed a female Baltimore Oriole, who was presumably feeding on berries, still sticking out like a sore thumb despite her muted yellow plumage. Shortly after, four immature orioles gathered on single bush. They called sporadically as they were perched. They didn’t seem to understand what to do, as if unsure what to make of me. Like the blackbirds, they, too, stared at me. I had my best look at young Baltimore Orioles yet – a excellent opportunity to unhurriedly note their washed-out orange plumage and their gray and white wings. As soon as I pressed forward, they flew to the trees, where they flitted around in search of food. Two young catbirds took over the bush.

A miniature pond had formed on small section the path from a stream of water trickling down. I had to jump my way across. I gingerly took a step, and then another step. Five young turtles suddenly darted from the grass I nearly stepped on, dived into the water, and buried themselves under the mud. During that split second they jumped, I could see that their shells were dark with orange lines.

I spooked so many robins every few yards the entire length I walked. They tore from out inside the berry-laden vegetation, crying Yeep! or Cuck cuck cuck! I lost count of the gray blurs and started rolling an estimated number, around three dozen. Many were adult age, though a few were speckle-breasted young. I didn’t expect so many robins here. Christine didn’t see so many on Saturday. This is the kind of number I would observe in the winter, the time when robins generally flock in larger numbers. Perhaps the individuals that are already done with breeding are now on the nomadic move.

Now back in the sanctuary, underneath the cool canopy shade, I heard the same Hairy Woodpecker family I saw last month. But after that, my descent on the white and red trails were quiet, with the exception of another young titmouse group. The number of robins sighted dropped drastically, although I did see a few more.

On the yellow trail once again – the other half of the pond loop – I began hearing the wood thrushes and pewees again. The Scarlet Tanager I heard calling from before was now singing. A group of a half-dozen or so Blue Jays jay-ed boisterously. I thought they were mobbing a raptor, but when I got close, they shut up. They were only talking to one another, apparently. I find it difficult to discern whether jays are talking or mobbing. (Personally, crows are easier.)

Towards trail’s end, I heard a pair Wood Thrushes duel. Down the trail, I saw a Red-trailed Hawk land high in a tree. A grackle and a blackbird moved in to protest its presence. It flew away promptly. I couldn’t tell if this was the same hawk from before, or a different one. I played in safe; I kept my Red-tail count at 1.

I observed 32 species on this hike. I was happy to exceed my goal of 25 and to hear a lot more singing from the migrants than I expected. Wood Thrushes and pewees, yes, but not Indigo Buntings and Scarlet Tanagers. Funny enough, no Red-eyed Vireos!

Brinton Brook Hike, Report 6-2017

Because I now work weekends during the summer, I missed the Second Saturday group hike on the 10th. I will have to miss Second Saturday in July and August as well.

I got the chance to hike Brinton Brook by myself this morning. Black and yellow flies began zipping around my ears as soon as I got out of the car. I looked up to the overcast sky, a bright uniform gray. The air was so muggy that it perpetually felt like that second just before rain starts to fall. The robins sounded muted through the thick air.

Now that we have passed into the latter half of June (the summer doldrums for songbirds), I expected to hear a handful songs. Few songbirds sing at this time, save for the ones that have a second or third clutch and still need to establish territory. Most only raise one clutch and take care of their young ones at this time. I did, however, start my hike with a sharp eye and ear for fledglings.

Traveling up the trail to the map intersection, I heard two different chipping notes. One was familiar and the bird immediately seen soon after: Northern Cardinal. He foraged in the bushes next to the path. The other note was unfamiliar. I pished to draw out the source. On the other side of path, an immature male Indigo Bunting popped up and perched on a woody vine. He looked like Sleeping Beauty’s dress at the end of Flora and Merryweather’s fight: his plumage was a messy tye-dye of indigo and brown. For more than a minute, he chipped and chipped, turning to and fro, calling for his parents or expressing his state of alarm. He flew to another vine, continuing to chip, so I walked away.

I could still hear him when I reached the intersection. Not another bird made a peep. Pishing produced nothing. As I continued along the trail towards the field, I heard another chipping note from the myriad of black locusts. It sounded sharper and more metallic. Utilizing echolocation to find a bird more often difficult that easy. After a couple minutes, I saw bird finally move. An adult male Indigo Bunting. He moved closer to me, still chipping. Based on his and the other bunting’s behavior, I presumed he was scolding me for pestering his offspring, so I moved on quickly.

The pond was mostly shallow and covered in lily pads. A few Red-winged Blackbirds sang and called from all around. Walking alongside the pond, I heard more robins, a Red-eyed Vireo, a couple Eastern Wood-Pewees, and a Baltimore Oriole. I couldn’t find any herons, Great Blue or Green, when I scanned the other side. A lone green frog called.

At the eastern end of the pond, the path narrowed because the vegetation had closed in on it. I paused a quick moment before crossing. I may not have been hiking the Hudson Highlands – where copperheads are about – but I (alone even with a cell phone) was still mindful about the possibility of a snake shooting towards me on the attack. As soon as I started walking I heard a rustle behind me. I looked back to see a black rat snake on the pond side of the path. It stared at me for a little before slinking into the water.

I had seen black rat snakes here before. The last time I hiked Brinton Brook, I saw three large ones swimming in the pond. Harmless, they are common in New York. They’re more likely to slither away from you when they’re scared rather than go on the attack.

At the blue trail’s beginning, I heard two Wood thrushes duel. The hike up to the power lines, of course, was quite dead, with exception to a small titmouse family.

The clouds were just starting to part away when I arrived the power lines. Minutes later, I saw mostly blue sky. The sun brightly shined. Now I was birding during a true summer day, hot and muggy. I observed a lot of bird activity: two Eastern Towhees, four Prairie Warblers, three Blue-winged Warblers, a couple more Baltimore Orioles, three more Indigo Buntings, two Field Sparrows, two loudly warblering House Wrens, and a Common Yellowthroat. From the woods I heard another Eastern Wood-Pewee and more cardinals. Many of these birds were singing and chattering all at once. The Prairies were flying about, and two of the Blue-winged were fighting. Numerous insects zipping around constantly threw off my focus.

I experienced my first birding sensory overload of the year. It was difficult to decide which single bird to settle on and to discern if it was a bird within a split second. But when the warblers came into view, I reserved my bins for them. I had only Prairies up to this point. It was a relief to finally see them. I also watched an Indigo Bunting sing perched atop of a nearby bush, his blue blazing in the sunlight. I also don’t often see Field Sparrows. It was wonderful to catch a sight of a pair.

I was relieved to re-enter the woods. Even though I now heard the construction of the golf course expansion at its loudest (I was hearing it throughout the hike since I started). The construction didn’t deter the birds from going about their business. I had walked into a miniature bubble of activity. A pair of Brown-headed Cowbirds flew about. Three voluble Hairy Woodpeckers sang, called, and darted from tree to tree. Another two male Baltimore Orioles – one adult, one immature – chattered. I disturbed a pair of Eastern Towhees into hiding. When I pished to coax the female out, the male burst forth and aggressively sang “Drink your tea!!!!”.

I continued. I heard more pewees, Wood Thrushes, titmice, and chickadees. At this point, I stopped keeping track of robins. I had seen a lot thus far – including immatures – and decided to estimate a number in the end. Shortly transitioning from the white to the yellow trail, I saw a Wood Thrush scoot along the forest floor, wary of my presence. Just ahead, in one spot, a Scarlet Tanager and Blue-headed Vireo sang. I tried getting on the vireo but failed. The tanager did fly into view, his red stunningly way more powerful than a cardinal’s. He sang even as carried an insect in his mouth.

Activity quieted down significantly as I further hiked down. Toward the trail’s end, I saw a few more robins, and heard one more pewee and the same Carolina Wren from the beginning. Before hopping back into my car, I stopped by the Weinstein pond, which was still as glass.

My hike lasted a little less than two hours. I might have been more patient and slow-going were it not for the humidity. Summer is my least favorite season for this reason….That means it’s time to visit the beach for shorebirds! Still, I was pleased to go around Brinton Brook and barely make it in time before the summer doldrums hit. I observed 33 species. Check out the eBird checklist here!
