- Comments: "Rare, potential first Kings County sighting. First seen swimming between pier 1 pilings after sunset. Smaller than ring-billed gulls. Faded hood only reaching the crown. Blackish bill, difficult to tell its true color, heavier than a typical BHGU's. Glaucous mantle. Dark primaries with small white spots, pale at the base à la RBGU. Relocated on pilings later."

Black-headed x Ring-billed Gull (hybrid) (Chroicocephalus ridibundus x Larus delawarensis) (1) CONFIRMED
- Reported Dec 29, 2021 15:56 by Doug Gochfeld
- Brooklyn Bridge Park, Kings, New York
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&q=40.6996104,-73.9973745&ll=40.6996104,-73.9973745

- Comments: "**Very rare. Spotted floating on the water at the Pier 1 pilings by Jer Thorp and Mike Yuan around nightfall, while I was viewing the marina near Pier 3 with HW. We sauntered over shortly after Mike texted, and after  a while scanning in the night we found it perched on one of the pilings. Small adult larus-type gull, noticeably shorter-legged than nearby RBGUs, pale back, black primaries with discernible white mirrors, bill seemingly intermediate between BHGU and RBGU, dark on head concentrated around auriculars, vaguely like winter Mediterranean Gull, though with some apparent light streaking bleeding towards hind-crown, a la RBGU. Structure appeared bulkier than BHGU. By the time I saw it, I could not discern bare parts color with certainty. Photos and video, though darkness made for difficult conditions. MY got some better photos earlier when it was less dark out. Perhaps my first of this hybrid combo."
