Prospect Park Rough legged Hawk records

Just as I figured.

Yesterday's sighting was the eleventh record the first RLHA seen in 22 years! The last sighting was April 25 1999   ( ) and the observer then was none other! A bird I remembered well on a BBC walk  as we don't get this very rare  bird ; my sighting was a flyover over Lookout Hill heading northwest.

To the observer of yesterday's bird over the ball fields I say congrats for a fantastic sighting. It was apparently a low flyer that terrific photos were had.

Prospect briefs Rover returns

Tuesday in Prospect was highlighted by the return of Rover the eagle.

On the Hammerhead in southwest Prospect Lake, Rover was seen perched in a tree by one of my supevisors. Later Rob Bate witnessed the eagle catching a fish from the lake, a catfish. There's plenty of catfish recipes we can pass along to Rover.It flew up towards Lookout Hill with its meal.

This morning saw the return of Martins. Sorry folks not that one; namely  3 Purple Martins over the lake spotted  early morning by Dale Dyer.

The last good mention regards Louisiana Waterthushes. A few different places were scenes for the tail bobbing bird: Ravine southern weir, Upper Pool,Pagoda's Lily Pool and a late report  of south lake shore behind 3 Sisters Islands. It's that time of the year

Gray breasted Martin ( pending) Prospect

Today's continuing bird focused on the outer/ Lower Lullwater,the body of water between Terrace Bridge and Peninsulas north shoreline /tip.

Most birders hung around on the pink concrete beach ( opposite the Terrace Bridge) hoping for the Martin's appearance. Behind that beach there was a tall ginkgo tree it perched at the top several times; it also perched next to the Bridge.

Early in the morning it perched over the small cove of the peninsula back hand ( the peninsula is shapes like a hand). I haven't heard it reported over the open lake or straying too far. It did disappeared for time gaps likely flying high on the wing.

If you are not successful ,there's always the Louisiana Waterthush. The walking bobbing warbler first spotted in Binnen water, worked upstream under the Nethermead Bridge where it was seen on the small weirs. I was lucky to see it-- thanks to Charles tip--on the small waterfall in the Ravine just in from Rocky Pass entrance.

Happy Easter everyone ! 🐰🐇🐣

Mega rarity swallow details from Doug, original finder Eastern prospect lake

Gray-breasted Martin (Progne chalybea) (1)
- Reported Apr 01, 2021 07:25 by Doug Gochfeld

- Prospect Park, Kings, New York
- Map:,-73.9689534&ll=40.6602841,-73.9689534
- Checklist:
- Media: 16 Photos
- Comments: "*****Potential MEGA. Very few records for the continental USA of Gray-breasted Martin or of any species in the "Snowy-bellied Martin" complex.
Changing observation now (on 04/03) from "Progne sp." to Gray-breasted, as that's what I now believe it most likely is, and it is easier for people to track through alerts when entered as a full species- these first two lists have photos for people to peruse as well. That said, I acknowledge the high level of uncertainty inherent in tropical Progne identification.

I First found this swallow from the south shore of the lake, opposite the Peninsula, as I was on my way out of the park. I was perplexed about its identity for quite a while, in part due to the dark, wet conditions, and the distance from the bird. It was starkly pale below, much like a Tree Swallow, except for an obviously dusky throat, and its upperparts were cold toned bluish, rather reminiscent of a dull Barn Swallow. It was not obviously larger than the couple of nearby Tree Swallows at first, which added to my confusion, as Purple Martins tend to impress me as dramatically larger than our other common swallows.
After ascertaining that it was indeed a Progne Martin, in large part by shape and flight style), additional views and photos cast some doubt on the null hypothesis of Purple Martin (brown flanks, apparently clean, unmarked underparts, little hint of a collar). I relocated to the Peninsula thumb, hoping for better views and photos. I did get some better views and pics. These showed that while my impressions of the underparts had been correct, it did indeed have a pale, mildly contrasting collar.

I had to leave the park after this, and was at this point waffling on the ID, and assuming this bird would prove to be part of a range of variation of Purple Martin which with I wasn't familiar. Examination of photos on a computer, and resources thereafter, and consultation with a couple of friends made me strongly suspect Caribbean Martin or another member of the Snowy-bellied Martin complex. I got the word out, and returned to the park, later, once the front passed and the light was better. This second encounter will be in a different eBird list, and this bird was last seen at least fifteen minutes after official sunset, at which point it was becoming too dark to adequately track it, so we could not ascertain whether and where it roosted. Many photos, though darkness hindered the quality. More photos and some video during the afternoon excursion.

Underside white like Tree Swallow except for dark grayish throat. Tail moderately forked. Bird too small for Purple Martin. Tail did not seemed forked enough for Snowy-bellied Martin complex. Gray-breasted Martin seems a better fit. Hopefully, many photos by Gochfeld and others will help resolve identification. (Changed species ID from martin sp? On April 3)"

Consensus on Martin species prospect lake

At least one line of consensus is assured about the mystery Martin flying and perching in Prospect Lake. The NYC RBA is saying it's a tropical species one of --until further analysis --pinpoints it's true identity (if ever): Cuban,Grey breasted or of 3 snowy bellied complex species. Stay tuned.

The mega Martin spent most of the day off the Peninsula Tip ( the rustic shelter) flying with Tree Swallows or alone. At one time to my luck after a tweet it perched in a birch on Music Island .Other birders watch from the Lefrak Rink shoreline plaza as this tropical Martin stuck to the area between the rink,peninsula and duck island.

If anyone's interested there's still the hen Common Merganser and Redthroated Loon on the lake...hmm I guess not with that celebrity super mega Martin around...

Swallow mystery

Much of the focus at Prospect Lake centered on a mystery Martin all over Prospect Lake today.

First appearing yesterday,found by Doug G, what was presumed a Purple Martin has been downgraded to an uncertain species identity. It could be an aberrant plumaged purple but suggestions are being thrown towards a tropical species possibility. These suggestions include Cuban ,Carribean or Gray breasted.

I'm very leery of posting anything here to create a wild goose chase. But if you are in the mood of chasing phantom geese, at least youll enjoy the beauty of Prospect park , then give it a shot and go for it! what's the worst if it was decided a purple? At least the pursuit was fun.

Prospect Lake swallows and morn warblers

Of the small number of swallows flying all over prospect lake,the one that stood out was Purple Martin.

Joining Tree,Barn and Northern Rough winged,the Martin was first spotted off the Peninsula by Doug G. Eventually it made its way over to West Island cove in later afternoon seen by a Mob.

Earlier when it was dreary cold, about 6 PINE WARBLERS settled in the Lullwater on both sides. I was fortunate for Linda Es tipoff to see one low male in poor light. I thought that was going to be my best look for PIWA.  Wrong. After work I sauntered down to the back road of the Pools. Just past the Lower Pool, I saw Kevin R looking at something on the ground. I figured I better get over there. And sure enough there's a bright male Pine in nice sunny light when it cleared up. My spring is made when I get my favorite warbler ( second is orange crowned).

The other highlight for me post work was the still present Red throated loon in the Lake. But what was special is that I saw the loon grab a fish! And I  enjoyed watching the loon swallow the fish as swallows flew above it. 🐟🐡🐡

I had no luck with the Martin but I avoided the mob given the circumstances ( still waiting my 2nd vax in two weeks)
