Sandhill Crane, Inwood Hill Park

sandhill_crane

Sandhill Cranes have a southern breeding range not too far north of Manhattan, in upstate New York, Connecticut, and Massachusetts. They frequently stopover in nearby Somerset, New Jersey, during migration. They breed in wetlands, and they will touch down in those or in expansive grasslands. They are not likely ever to land in Manhattan, and they are known to fly very high when migrating, which explains why they are so rarely observed here despite having a nearby presence and being large, unmistakable birds.

It never occurred to me that they even were a possibility until a birder reported one flying over the Bronx Zoo in May 2016. A report of seven Sandhill Cranes flying over Fort Tryon Park in Manhattan followed in December 2016. Then three more were seen over Fort Tryon in January 2017 by the same observer. It’s likely that another two were seen from midtown over the Hudson in December 2017.

These observations stoked my interest, but I saw no practical way to get the birds. Sandhill Crane appearances were not part of a daily movement pattern — they were notably infrequent. Plenty of birders were reporting from the Inwood area most days and not seeing any cranes. A dedicated Sandhill Crane watch of any length would almost certainly produce none. Still, it was a species to keep in mind.

Yesterday, 16 October, I went to Inwood Hill Park to do some sky-watching and river-watching. It was a decent, sunny morning with moderate northwest winds, and I was seeing some Bald Eagles floating overhead. Brant flocks were moving low down the Hudson.

At 11:48 a.m. I saw high-flying bird over Inwood Hill with just my eye and I focused my binoculars on it. It clearly was not a goose or a raptor. It had long, broad wings beating slower than a goose’s would, a long, outstretched neck, and feet trailing outstretched behind it. As it turned into sunlight, I noticed grey wings and body, and briefly a pale cheek patch and darker crown — a Sandhill Crane, flying southwest over the Hudson.

With only three other birders on record as having observed a Sandhill Crane in Manhattan in three other occurrences, the species must be considered among the rarest few I have had here. The North American population appears to be continuing a multi-decade trend of population increase, so perhaps it will appear here more frequently in the future.

Sanderling, Governors Island

OLYMPUS DIGITAL CAMERA

Yesterday, 7 September 2018, Mary Beth Kooper found a Sanderling on the rocky northwest shore of Governors Island and quickly reported it on Manhattan Bird Alert (@BirdCentralPark on Twitter) at 12:23 p.m.

The Sanderling species had been a focus of mine ever since 23 July 2018, when another birder photographed three such birds on the tiny beach north of Yankee Pier on Governors Island. Sanderlings strongly prefer to forage on beaches, a habitat Manhattan almost completely lacks. With no prior historical eBird reports of Sanderling in Manhattan other than during hurricanes or as flyovers, I had not previously considered it likely as a next life bird. But new evidence requires reconsidering one’s outlook.

First, there are a lot of Sanderlings at nearby beaches in Brooklyn and Queens during the summer, sometimes thousands of them at Breezy Point, for example. The species is abundant throughout its range on appropriate habitats. Not only do birds wander, but they pass over other locations on their way to where they want to go. So Sanderling flyovers should sometimes be visible in Manhattan, and bad weather might sometimes bring birds down.

Second, even though Sanderlings prefer beaches, they are capable of feeding elsewhere. And the Governors Island beach, though small, is still large enough both to be visible to flying birds and accommodate the feeding needs of a flock. At low tide the beach is at least 300 square meters.

23 July 2018 was just such a bad-weather day — strong southeasterly winds were blowing, the result of a low-pressure system in the Atlantic. I was running in Central Park when I received the alert, and I raced home quickly and made it to Governors Island in less than an hour from the time of the alert. But the alert, just after 3 p.m., came as the tide was rising most quickly. So by 4 p.m. the small patch of sand had become submerged, and the Sanderlings had flown.

I tried again the following day at low tide. And I continued trying on many other days, including on 23 August, one day after another Sanderling had been photographed on the southwest shore.

I posted on Manhattan Bird Alert that birders should be checking the rocky shores of Governors and Roosevelt Island for shorebirds, including Sanderling and Ruddy Turnstone. I mentioned that Sanderlings, Western Sandpiper, and White-rumped Sandpiper closely resemble more common Semipalmated Sandpipers, and that attention must be paid to subtle differences.

I am delighted that Ms. Kooper kept this advice in mind and found a very cooperative Sanderling.

I took the 2 p.m. ferry, landed on Governors Island by 2:08, and after a few minutes of walking had the Sanderling in sight. I was treated to close, naked-eye views from above the rocks of a bird I had spent many days seeking.

194 Manhattan Species Before June

A good winter combined with a very good spring helped me to set a new pre-June Manhattan record of 194 total bird species for the year 2018. The previous pre-June best was 189, shared by Andrew Farnsworth and me in 2017.

How good is the record? In 2012 I had 212 total birds for year but only 164 as of May 31. Since then my mid-year totals have varied: 173, 182, 175, 180, 189 for 2013 to 2017. 194 clearly is an outlier, and probably on-par with or a bit better than my best big year total of 214.

One reason for a general trend up in these counts is the increasing number of birders who issue chaseable reports, mainly through the Manhattan Bird Alert service I operate on Twitter (@BirdCentralPark), but increased use of eBird also makes a difference.

When @BirdCentralPark began in May 2013 we had only 200 or so followers. Now we have over 2,500, and we get reports tweeted at us by casual or visiting birders often in addition to the many reports from our regular users. It has become increasingly likely that good birds will be found and reported, making Manhattan birding more rewarding for everyone.

 

Best Birds of 2017

Despite initially having no intention of doing another year of competitive birding, I ended up doing one anyway, and I put up my best numbers ever: 214 Manhattan birds for 2017, extending my own ABA-countable big-year record from 2014 by another bird.

Usually I write about my “best” (rarest) birds of the year, but I have already written about some of them on my blog, and will touch on all of them in the highlights below. Just for the record, here is how I would rank them:

  1. Hammond’s Flycatcher
  2. Red Phalarope
  3. Tundra Swan
  4. Clapper Rail
  5. Least Bittern
  6. Cattle Egret
  7. Lesser Yellowlegs
  8. Boat-tailed Grackle

Coincidentally these also were the eight life Manhattan birds I added in 2017.

Here are some chronological highlights of the year:

  • January 10: Found my first good bird of the year, an Orange-crowned Warbler at Little Hell Gate marsh on Randall’s Island. This species would turn out to be unusually common during both spring and fall migration.
  • January 12: Mute Swans used to be seen many times throughout the year on Manhattan waters but lately they have become rare. A juvenile swimming at Little Hell Gate marsh was the only one I had in 2017.
  • February 14: Found and photographed Snow Buntings on Randall’s Island’s northeast shore. I would end up finding another pair of Snow Buntings at the same location in November.
  • February 16: Found and photographed an adult Glaucous Gull on the rocks off FDR Park on Roosevelt Island. It offered close views and lingered at the location for at least a couple weeks. It may also have gone on to appear at the Reservoir, where I had an adult Glaucous Gull—twice.
  • February 17: Canvasbacks on the Hudson at Riverbank State Park. These continuing birds were north of the usual West Harlem Piers location and I might have missed them on my first visit there on a cold, blustery day. I nearly gave up on my second try before deciding to check from Riverbank State Park, where they came clearly into view.
  • March 4: Long-eared Owl at Shakespeare Garden.
  • March 15-17: The unprecedented American Woodcock event. Some saw as many as 40 on the 16th. They were everywhere, in numbers never seen before in Central Park. At least one Wilson’s Snipe, too. My and Central Park’s first woodcock of the spring migration came on the cold evening of the 12th, a single bird flying up in Tupelo Meadow. I was delighted just to have one—in some years they can be very hard to find in Manhattan. I had no idea what was to come only days later.
  • April 3: Purple Sandpiper on the rocks south of FDR Park on Roosevelt Island. Yes, the species has become annual at this location and more people had it this year than ever before. But it is still a treat to see what was for a long time a true mega-rarity for the county.
  • April 11: My life Cattle Egret at Penn South. I raced to reach it, worried that the bird would not stay long in such a heavily-trafficked area, and was first on the scene. Then the bird stayed for nearly a month.
  • April 17: Immediately I suggested to Robert DeCandido and group that Purple Finches were likely today and Strawberry Fields would be a good place to find them, the birds appeared high in the trees.
  • April 21: Wild Turkey at Maintenance in the Central Park Ramble. At first I thought the prior evening’s eBird report from the Loch might be a hoax. Failing to find this large, conspicuous bird in the North Woods with Robert DeCandido the next morning increased my concerns. Then an afternoon Turtle Pond eBird report from a visiting birder came through at 6:33 p.m., and I was off on the chase and was first to re-find it and issue a Manhattan Bird Alert. It was my life Central Park Wild Turkey.
  • April 24: Greater Yellowlegs at Randall’s Island Little Hell Gate Marsh, a species that appeared more often than usual this year in Manhattan.
  • April 25: I went out in the rain to get the White-eyed Vireo reported near Sparrow Rock and made a second such trip to get the Blue-winged Warbler. The latter species was unusually scarce this year.
  • April 26: Saw and issued an alert on the Barred Owl over the Rustic Shelter in the Ramble in the morning. But my day was not done.
  • April 26: Red Phalarope on Randall’s Island’s northeast shore rocks in the afternoon. Briefly had a naked-eye view of a breeding-plumaged female as it perched just feet from me on the rocks at the east end of the saltmarsh.
  • April 27: Huge day—Worm-eating Warbler with Roger Pasquier; Yellow-throated Warbler near Tanner’s Spring and Yellow-throated Vireo at Shakespeare Garden Overlook, both with Robert DeCandido.
  • April 28: Had two Marsh Wrens near Bow Bridge very early, the only ones of the spring in Central Park. Then went to the North End and had Orchard Oriole with Robert DeCandido. I returned to the Ramble get the Pine Siskin at the feeders just before noon. Robert would go on to find a Clay-colored Sparrow below Nutter’s Battery by Meer. After an alert of the Clapper Rail at the Loch after 5 p.m., I ran there and saw it. Then, with some daylight still remaining, I walked toward the Meer with Tom Fiore and began searching for the Clay-colored. Karen Fung re-found it and issued an alert when Tom and I were nearby. We saw not only that but also our first White-crowned Sparrow of the year near it. An amazing day of birding!
  • April 29: Strong southerly winds brought some warblers much earlier than usual: Hooded, Cape May (singing near Tanner’s Spring), and Tennessee (singing at the Upper Lobe). A giant Snapping Turtle, the largest I have ever seen in Central Park, also appeared at the north end of the Upper Lobe.
  • April 30: Least Bittern over the Gill, the first appearance of this species in Central Park since 1989. After seeing it, I suggested to Ryan Zucker that we chase an alert of a Lincoln’s Sparrow at the Pool, as we could reach it quickly by subway and it was likely to stay in place. This decision proved fortuitous, as we not only got the Lincoln’s, but we also ended up being right on location when a Kentucky Warbler was found by the Loch. Getting Winter Wren and Least Flycatcher was good, too.
  • May 1: Andrew Farnsworth and I went to Governors Island mainly to try for Boat-tailed Grackle, which had been reported recently by a group visiting the island. We missed that, but Bobolinks were a great consolation prize.
  • May 2: I returned to Governors Island and found a male Boat-tailed Grackle.
  • May 3: Robert DeCandido’s calls quickly deliver a rare Black-billed Cuckoo. Later, in the afternoon, while watching for warblers at Summit Rock I hear of an American Bittern said to be at Tupelo Meadow. I go to look for it and do not see it. Then I meet a birder who claimed to have seen the American Bittern himself. I issue an alert at 3:08 p.m. and look for it again, this time along with many others. No one sees it. I wander back to Summit Rock. After 6:00 p.m. I encounter a birder who reported having seen the American Bittern along with a crowd of birders at Tupelo and even had a photo of the bird. How could this be when no new alert has been issued?  I issue the alert myself and run there. Success, finally!
  • May 7: A late-afternoon report of Semipalmated Sandpiper at FDR Park has me going there during light rain at 4:55 p.m. Then an alert of Eastern Whip-poor-will at the Pond arrives. I head to the Pond’s west side, by the waterfall, find the bird, and issue an alert with a photo of the tree where it was roosting.
  • May 9: I bird Central Park early with Robert DeCandido until I get an alert of Blue Grosbeak continuing at Battery Park. I find the grosbeak quickly, well north of the beehive location where it had earlier been noted. Then I start looking for the Summer Tanager, which Gabriel Willow had found at the north end of Battery Park. This takes over an hour, but eventually the tanager reappears and gives a close view to many.
  • May 11: Found my first Yellow-billed Cuckoo of the year south of the Rustic Shelter with Robert DeCandido.
  • May 14: Bank Swallow near the Reservoir North Pump House.
  • May 18: A male Mourning Warbler is found on the rocks beneath Belvedere and offers a close, clear view to many in the early evening.
  • May 19: I find a Bicknell’s Thrush near the Loch with Robert DeCandido and his group. The thrush sings in response to playback, giving the group its first-ever Bicknell’s.
  • May 21: I hear and then see a singing Willow Flycatcher at Turtle Pond.
  • May 23: An hour-long stakeout of Humming Tombstone gets me the reported Yellow-bellied Flycatcher.
  • May 27: I bring show Robert DeCandido and group a singing Acadian Flycatcher at Warbler Rock—my last Central Park migrant of the spring.
  • June 2: My best look at Black Vultures, with Robert DeCandido, over the North Woods.
  • June 14: After a week of trying to get a Black Skimmer on the East River (as had been reported) or over the Meer, I went to Pier 45 in the West Village with Ryan Zucker. After seeing at least two Black Skimmers near the west shore of the Hudson, we saw three fly close by the pier. It’s a cool bird that very few birders ever have seen in Manhattan.
  • August 14: I wasted no time in getting to Sherman Creek to chase a report of Semipalmated Plover, a shorebird one does not get every year here.
  • August 25: The Lesser Yellowlegs found late the day before stayed another day, giving me another life bird in the maintenance puddles of Governors Island.
  • September 9: The first Bald Eagle and Broad-winged Hawks moving over Central Park—always a great way to begin the fall birding season.
  • September 10: It took me three attempts over two days to get the Connecticut Warbler at Sparrow Rock, but the hours of watching were worth it, as no other chaseable reports arrived this fall—a sharp decline from the relative abundance of the past few years.
  • September 16: After a Western Kingbird was photographed too late to chase yesterday on Governors Island, I went on the first boat and ran to the location on the south hills on a hot, sunny day. The kingbird never re-appeared.
  • September 29: The Philadelphia Vireo on Robert DeCandido’s walk near Green Bench in the North End gave everyone a great view of a bright bird.
  • September 30: Joe Girgente’s Dickcissel at Renwick Ruins on Roosevelt Island proved a pivotal bird for me. Both he and I got extended, close views, but no other Manhattan birders saw the species this year.
  • October 12: Quick chase to Randall’s Island’s northeast-shore saltmarsh yields both Nelson’s Sparrows and a Saltmarsh Sparrow (rarer) at close range.
  • October 14: Ryan Zucker texted me with a mid-morning report of Vesper Sparrow on the northeast fields of Randall’s Island. I ran over and saw it with him, the first of several Vesper Sparrows I would see in an unusually good fall for them.
  • October 22: First found the previous morning, the Fort Tryon Park Heather Garden Yellow-breasted Chat was not seen again the previous day. That is just as well, as I went to chase a more proximate report from Andrew Farnsworth in Sutton Place and did not re-find it. The next morning another alert from Fort Tryon arrived, and I went to chase it. When I arrived a handful of birders already were on the scene, some of whom had seen it just five minutes ago. I waited another forty minutes before it reappeared and soon gave me a brief look from the Heather Garden Terrace. This would be the last report of the year for the species in Manhattan.
  • October 22: But my day was not over. Shortly after returning home, I received an alert that Stefan Passlick had found an Eastern Meadowlark on a North Meadow ball field. It lingered the rest of the afternoon to the delight of many.
  • October 27: Red-shouldered Hawk would prove scarce this fall. I was happy to get an early one flying low over the Loch with Robert DeCandido and his group.
  • October 30: I have written at length about the evening’s Great Horned Owl over Evodia.
  • November 10: On a cold day with strong northwest winds Andrew Farnsworth and I had some low flyovers of Bonaparte’s Gull on the Dyckman Street fields, a very tough species to ever see in Manhattan. Upon returning to Central Park I was treated to another low flyover, that of Northern Harrier.
  • November 18: With widespread rain approaching, I decided to run to the Native Plant Garden on the southeast side of Randall’s Island, where I had American Tree Sparrows in late November the year before. To my delight one was there again.
  • November 23: I was extremely fortunate to be on the East River Greenway, on my way to Randall’s Island, when a low-flying Tundra Swan passed over the island and overhead on its way south. A private alert from a birder on Randall’s Islands northeast fields help assure this rare swan would not be missed.
  • November 23: Later that afternoon I chased and saw a Virginia Rail in the Central Park Ravine, another great Stefan Passlick find. This bird stayed at the location for many days.
  • November 26: I was one of the first to see the mega-rare Hammond’s Flycatcher that lingered for over two weeks in the Central Park Ramble.
  • December 3: Finally saw (along with Robert DeCandido and his group) the Boat-tailed Grackle (my first for Central Park) that had been associating with a large Common Grackle flock in the park possibly for as much as two weeks.
  • December 10: With the closest subway to the Dyckman Fields closed along with some stations on the 2, I had to go well out of my way to reach the three Horned Lark that were reported there. But even two hours after the initial sighting they remained, foraging around a puddle on the southernmost ball field. All of this came after already walking the length of Randall’s Island and back earlier in the morning with Ryan Zucker.
  • December 13: The late afternoon and evening produced a memorable goose migration event of enormous size. Many large, low-flying flocks of Snow Geese were seen and later heard, even hours after sunset, driven by unusual cold and favorable winds.
  • December 17: After several failed attempts this fall to hear an Eastern Screech-Owl at Inwood Hill Park, I was glad to receive reports of one being seen and heard on the 15th. I ended up hearing it whinny but never saw it.

Boat-tailed Grackle, Central Park

Female Boat-tailed Grackle (credit: AllAboutBirds.org)

As I have written before, Boat-tailed Grackle is not a species you should expect to find in Central Park even though it breeds in the New York City area and in neighboring New Jersey. When it is reported in Central Park, it is almost always a mistake. Common Grackles vary in size and tail length, and if you look at hundreds of them you are likely to find some that look larger than the others. A male Boat-tailed Grackle is not easily distinguished from a large Common Grackle by appearance alone, though the rounder crown shape of the Boat-tailed and the very large tail, often held in the shape of a “V,” are key features. Song and calls diagnostic for distinguishing these two species.

If you want to confidently identify a Boat-tailed Grackle amidst a loud flock of Common Grackles, your best hope is to find a female or immature. It’s overall brown color suggests Rusty Blackbird, but its long, thick bill and much larger size (as large or larger than Common Grackles) easily clinch the ID.

Recently in Central Park eBird reports of female Boat-tailed Grackle have appeared, with the first being on November 17. This report failed to give a specific location and was entered after sunset, despite referencing a morning birding time. A more reliable report, complete with photo and Sheep Meadow location, was submitted on November 25. This one also was entered late, but not so late as to make chasing impossible. I received the eBird alert at 2:49 p.m. and shortly after 3:00 I was running to the southern end of the park to do some searching.

By then the large grackle flock reported and photographed in the early morning was gone. It was a mild day, and the Sheep Meadow and surrounding lawn areas were filled with people. I found a smaller Common Grackle flock in the trees of the Hallett Wildlife Sanctuary, but I could not pick out any Boat-tailed Grackles.

The following day, that of the Hammond’s Flycatcher discovery, another eBird report listed Boat-tailed Grackle. this time in the Ramble where I had already spent much of the day.

Two days ago, on Saturday, December 2, I had what I thought was a prime opportunity. A user of Manhattan Bird Alert reported a female Boat-tailed Grackle among a large Common Grackle flock on Cedar Hill. Minutes later, as I was on my way, this finder noted that the flock had been startled and flew south toward the Boathouse. Despite much searching in that area and in areas to the south, I never found the flock.

Another bird alerts user reported seeing the flock at Maintenance and then watching it quickly fly north. I headed north, scanning the lawns on the park’s west side. I did not find any grackles whatsoever.

Yesterday I was birding with Robert DeCandido and Deborah Allen’s group, which was on its way to the Pond to see warblers and waterfowl. I remarked to Robert, as we were passing Cedar Hill, to keep an eye out for grackle flocks.

As we approached the Sheep Meadow, I saw a massive blackbird flock — hundreds of Common Grackles along with many European Starlings. I quickly eyed a leucistic Common Grackle, and remarked that it probably was the same one photographed on November 25 in the flock with the female Boat-tailed — which might be here, too.

The flock flew west, re-settling on the northwest corner of Sheep Meadow. I ran to chase it, and began scanning. Soon another member of the group spotted the immature (likely female) Boat-tailed Grackle under a nearby tree. We got close looks and were able to take good photos.

For me and everyone else in the group it was a new lifetime bird for Central Park. We later had the bird again that day in the trees of Hallett.

Prior to November, the last verified report of Boat-tailed Grackle in Central Park was on April 20, 2011 — a male that seemed to have been lingering in the area south of the Meer for perhaps a couple weeks, and whose distinctive sounds were noted.

 

Snow Buntings, Randall’s Island

OLYMPUS DIGITAL CAMERA

Snow Buntings are a rarity for Manhattan. I am delighted to have had them for a second time this year (the first was on February 14, at the same location). Yesterday, November 11, I saw and photographed two Snow Buntings on the rocky northeast shoreline of Randall’s Island, opposite ball fields 39 and 40. They have been reported continuing at the this spot again today.

In other birding news, the cold front that passed through on the morning of November 10 brought strong northwesterly winds all day, which led to decent raptor and waterfowl flight. It was the first productive day for observing diurnal flight in Manhattan for over a month. We have been stuck in a cycle of either southerly winds (driven by strong low pressure systems) or northeasterly winds.

The latter are generally unproductive for seeing raptor flight over Central Park, as birds, which want to move west away from the coast anyway, are deflected even further west, over the Hudson and into New Jersey. For example, on November 8 the Quaker Ridge (CT) hawk watch had a record-high one-day total of 277 Red-shouldered Hawks. Manhattan birders reported none that day.

At Inwood Hill Park on November 10 I tallied some new birds for the year: Northern Harrier, Bonaparte’s Gull, and Snow Goose, bringing my 2017 New York County total to 209.  I had only a single Red-shouldered Hawk there. I had Northern Harrier in Central Park again upon my return just before 2 p.m.

Lesser Yellowlegs, Governors Island

I had my first Greater Yellowlegs in April 2013 at Sherman Creek. Since then I have had the species at least once every year — three times in 2017. Given that the Eastern population of Lesser Yellowlegs is somewhat larger than that of Greater, and that New York City shorebirding hotspots in other boroughs record relatively similar numbers of these birds, it is a mystery why Lesser Yellowlegs is so rarely observed in New York County (Manhattan).

Prior to yesterday, there had been only two eBird reports of Lesser Yellowlegs in Manhattan since 2010 — an unchaseable flyover in April 2010, and an appearance on the mud flats of Inwood Hill Park in July 2016 that was entered a couple hours too late to chase before the tide rose.

Yesterday, August 24, the fenced-in puddles on the southeast side of Governors Island, which have been hosting a variety of common shorebirds since spring, finally produced a rarity. After 3 p.m. Gabriel Willow of NYC Audubon found a Lesser Yellowlegs feeding among a mixed flock of shorebirds that included Least Sandpiper, Semipalmated Sandpiper, a single Solitary Sandpiper, and Killdeer.

With the last ferry to Governors Island leaving on weekdays at 4:15 p.m., I could not do a same-day chase.

Today I took the first ferry of the morning, at 10, hoping that the Lesser Yellowlegs did not join in what was a large overnight flight. To my delight it and all the other species mentioned above were still present.

A Great Week of Winter Birding

I am not doing another public big year, but I am birding. This week produced some of the best finds of the winter.

On February 14 I had two Snow Buntings on the northeast shore of Randall’s Island, and at least one of them posed for a close photo.

Snow Bunting

That same day I also had a Red-throated Loon, my first of the season and the first one I have had in nearly two years, seen from the same location swimming in the East River.

The day before I had Common Loon on the Reservoir, a species I had only once in 2016. Generally, Common Loon is the easier of the two to observe in Manhattan, not only on the rivers but also in the sky. But last fall the loon flights were nearly all very high, out of the range of my binoculars (I do not use a scope). I recall seeing at least a handful of loon flyovers in previous years at more accessible heights. And the loons were not touching down in the rivers as far as I could tell, which seemed odd. In the winters of 2012 and 2013, seeing loons on the rivers was easy — they were visible in decent numbers (1-4) on nearly every trip to the Hudson or the East River.

The best bird of the week was the immature Glaucous Gull I had on the 16th at Four Freedoms Park on Roosevelt Island, which is part of Manhattan. There have been a few reports of such a Glaucous Gull in the area recently, including briefly on the Central Park Reservoir. I was delighted to get a closeup photo of the bird.

Glaucous Gull

On the 17th I chased a Manhattan Bird Alert (Twitter) report of Canvasbacks at West Harlem Piers Park, a flock that had been appearing occasionally at this location in recent weeks. That is also where I had a flock of Canvasbacks in February 2016. When I did not see them at the tweeted location, I climbed the bridge to Riverbank State Park and found the flock just north of 135th Street by a water treatment plant. This time my photo had to be from afar.

Canvasbacks

Today, the 19th, I had Greater Scaup off Randall’s Island. I believe that the relatively mild winter — after what was briefly a very cold mid-December start — has caused fewer scaup to pass through the area, and probably also fewer of other species, such as Long-tailed Duck, which has been absent from Manhattan reports so far in 2017.

Bobolink, Central Park Oven

The Bobolink in general is a common bird, but it is a very difficult one to observe in Manhattan. Venture a few miles west, to the New Jersey Meadowlands, or to the coastal marshes of Brooklyn and Queens, and you can find plenty of them during spring and fall migration. You also can observe their migratory flights very early in the morning over Manhattan. Sometimes you can hear their flight calls. Rarely they alight on trees in Central Park in passage, never lingering long before continuing on.

Around 10 a.m. today I encountered AMNH Ornithologist Joseph DiCostanzo and Lenore Swenson in Tupelo Meadow. They told me that they had learned of a male Bobolink in the Oven forty minutes prior, and that they had observed it themselves before it flew off and was not re-found. Joe had attempted to issue an alert on the bird but the email apparently did not go through.

I had come across Bob “Birding Bob” DeCandido and his group earlier and I was birding with them when I got the news. We eventually made our way to the Oven but did not observe the Bobolink. Along the way we had a mystery flycatcher, seen only briefly, and my first-of-season Ruby-throated Hummingbird at Maintenance Meadow.

As a small digression, I should mention that I had a great time birding with Bob. Many know that Bob uses recorded calls and songs to draw in birds, as do many top birding guides. Birds that are perching still sometimes move and reveal themselves; some birds that are out of sight will fly in to check out the commotion; and some that are in sight but high up will descend to levels where they are more easily viewed. The result is that members of Bob’s group see a lot of birds and often get excellent views of them. I certainly had better views than I usually do on my own.

Yesterday, Bob found a Yellow-billed Cuckoo in Tupelo Meadow. I had remained in the Maintenance Meadow, along with many others who were part of a different birding group. Bob ran back to Maintenance to let everyone — not just his group — know of the cuckoo. We enjoyed extended views of the bird flying and foraging high over Tupelo.

Today, after initially striking out at the Oven in search of the Bobolink we moved on to Swampy Pin Oak. Warbler Rock, and the Rustic Shelter, where we saw Indigo Bunting, Great Crested Flycatcher, Eastern Kingbird, and Blackburnian Warbler, among others..

Bob suggested we finish with one more pass over the Oven and then onto the Point. As we we turned onto the dirt path leading to the Point, I began to hear Bobolink song. So did Bob, and he already had the bird in sight, atop a bare tree over the Oven. The Bobolink continued singing loudly, moving around to various high perches both at the Oven and later toward the north to the Captain’s Bench area.

This was my first visual Bobolink in Central Park — I had heard one singing two years ago in the North Woods. What a way to end the morning! With the temperature rising and warblers becoming more scarce, I headed home.
