Sterling Forest - 20th May

A trip up to Sterling Forest to try and connect with some more migrants. The day started well with singing warblers all over the place. Blue-winged and Prairie Warblers were the commonest, and easily seen. It took a while before the first Golden-winged Warbler was found, but  eventually one showed well. A hybrid Blue-winged x Golden-winged (backcross Brewster's x Golden-winged we think) provided a pleasant diversion. Bird of the day for me was the Black-billed Cuckoo however, showing briefly, but very close. We had heard a few calling, but only saw the one bird. Yellow-billed Cuckoo were also very vocal.

Hybrid Golden-winged x Blue-winged Warbler. Note the wing pattern like a Blue-winged, a golden crown like a Golden-winged, and the white throat. It was also singing the Blue-wined song.

Central Park spring 2017

Spring migration started quite late as the first week or so was very wet and many birds were held up. A big push came through on the night of Monday 15th/ Tuesday 16th, with 27 species of warbler seen by me so far, including 21 on the 16th.

Warblers so far this season:

Northern Parula: Daily since 28th April.
Tennessee: Single birds near Turtle Pond on 4th May, and at the Captain's Bench on 9th May.
Blue-winged: Single birds at Strawberry Fields on 28th April, and near Summit Rock on 16th May.
Nashville: Seen between 28th April and 11th May.
Yellow: Daily since 28th April in small numbers.
Chestnut-sided: Small numbers from 10th - 23rd May
Magnolia: Daily since 6th May
Cape May: A very good year for this species, with daily sightings from 2 May to 16th May, including 5 on the latter date.
Black-throated Blue: Daily from 4th May
Blackburnian: A late arrival with the first sighting on 16th May. Suddenly they seemed everywhere!
Yellow-rumped: The first spring warblers to arrive, with the first birds on 15th April. Most have passed through already, the last sighting was 17th May.
Black-throated Green: Daily from 4th May
Prairie: Single birds on 28th April, 6th and 9th May.
Palm: Common from 28th April until about 9th May, one of the first warblers to disappear.
Bay-breasted: An excellent year for this species. Daily sightings between 10th and 17th May, with at least 4 on 16th.
Blackpoll: Small numbers from 30th April, an early date for this species. Increased steadily, becoming the commonest warbler by about 17th May.
Yellow-throated: The only rare warbler this spring, a single bird on The Point on 28th April.
Worm-eating:  One bird on 10th May, and 2 on 16th.
Black-and-white: First seen 28th April, and daily since then.
American Redstart: Seen daily since 28th April
Ovenbird: 8 birds on 30 April, and pretty consistently since then.
Northern Waterthrush: First seen on 28th April, and every day since then.
Louisiana Waterthrush: Single birds at The Point on 28th and 30th April.
Common Yellowthroat: Seen daily since 28th April.

Hooded: A female in The Ramble on 6th May, and a male at Tanner's Spring on 16th May.

Additional warblers recorded by others included: Mourning, Kentucky, Orange-crowned.

Tennessee Warbler in Central Park - 4th May

Having a slightly later start than I would have liked, I decided to bird the North Woods this morning, thinking it would give me more time in the field, and less time marching. It was inevitable therefore that something good would be found in the Ramble, and sure enough, when I checked Twitter at 9:10 I saw that a Tennessee Warbler had been found singing by Turtle Pond. That was only a mile and a half away! I hot-footed it down there and was on site by about 9:30. A brilliant male, feeding actively in a tree, pausing occasionally for a burst of song.

Other first-of-year birds so far this week included: Cape May Warbler, Chimney Swift and Orchard Oriole by Summit Rock and a Spotted Sandpiper near the reservoir on Tuesday, and Black-throated Green Warbler and Black-throated Blue Warbler in the North Woods today.

Least Bittern in Central Park - 30 April

After a not-particularly birdy day at Doodletown on the 29th I decided that the best way to hit my target birds for this spring (Tennessee Warbler, Black-billed Cuckoo, Philadelphia Vireo, Least Bittern, Virginia Rail) would be to hang around with other birders, so I headed in to Central Park.

My plan bore fruit almost immediately when a twitter alert went out that a Least Bittern was perched in a tree above The Gill. And lo, it was true! What a great bird, and one of my main targets for spring down, quite unexpectedly.

Other new birds for the season included lots of Ovenbirds, Scarlet Tanager, Rose-breasted Grosbeak and Blackpoll Warbler. There were lots of Thrushes all over the place, including Veery, Wood Thrush, Swainson's Thrush and Hermit Thrush. The Red-headed Woodpecker put in a show at the feeders, all-in-all an excellent day.

Yellow-throated Warbler in Central Park - 28th April

The past week has been pretty wet, and few migrants have managed to make it this far north. Friday was set to be dry, so I got into Central Park by about 6:00am, and started at Strawberry Fields. Immediately it was clear that there had been a major fall. Every treetop was alive with warblers. The predominate species was Yellow-rumped Warbler, but soon enough we started picking up other species. A couple of Palm Warblers were the first non-yellow-rumps, followed by a Northern Parula, and American Redstart and then a Blue-winged Warbler. A White-eyed Vireo circled the area a couple of times, and a Blue-headed Vireo also showed up. A gorgeous Baltimore Oriole was next, followed by the first of many Black-and-white Warblers, and a lovely Yellow Warbler.

Next stop was the swampy Pin-oak which had a host of Ruby-crowned Kinglets, and singles of Common Yellowthroat, Nashville Warbler and a Northern Waterthrush. More Yellow Warblers here, as well as a Green Heron and a Hermit Thrush.

The last stop of the morning was The Point where a single tree produced a second Nashville Warbler and a Yellow-throated Warbler (ssp. albiloris), as well as another American Redstart. Nearby in the willows by The Oven was a Louisiana Waterthrush, a magnificent male Purple Finch and brief views of a Prairie Warbler.

The lores of this Yellow-throated Warbler are white, suggesting it is of the central race, Dendroica dominica albiloris. Compare this with the D. d. dominica that I saw at Valley Stream in April 2015.


This was first pointed out to me as a Northern Waterthush, but it is quite clearly a Louisiana Waterthush. (unstreaked throat, bubble-gum pink legs).

Prothonotary Warbler - Marine Park - 15th April

A Prothonotary Warbler was found in the week at Marine Park in Brooklyn. It hung around for a few days, so I decided to make it my first stop on Saturday morning. It performed amazingly well, regularly forcing me to take a step or two back to keep it in focus!

After that good start to the day I had a quick walk around the ponds at Jamaica Bay. The water level in the East Pond was very high so there was very little to see apart from Barn and Tree Swallows hawking over the water, a pair of Peregrine screeching at each other and a flyby Little Blue Heron.

The West Pond path has been rebuilt at last, but is not open yet. There weren't many birds here either, a single calling Eastern Towhee was the highlight.

Prothonotary Warbler has to be one of the best looking warblers. The word means " a chief clerk of any of various courts of law" (Merriam-Webster). It is attached to this bird "with reference to the saffron colour of the robes worn by clerks to the Pope" (Oxford).


It spent the entire time gleaning tiny insects from the leaves of the plants growing around the rocks near the Nature Centre.

Texas trip - Attwater Prairie Chicken NWR - 29 March

On the way from Houston back to the Austin area we went via the Attwater Prairie Chicken National Wildlife Reserve. A splendid place, it is one of the last strongholds for the Attwater subspecies of the Greater Prairie Chicken. The morning I went there was an enormous thunderstorm so I had to wait until about 10:00am, by which time the birds weren't calling. It was still a good spot, with quite a few Loggerhead Shrikes, plenty of Eastern Meadowlark (but no Western unfortunately), and 6 Northern Bobwhites, one of which posed for a picture.
