YELLOW-LEGGED IND, ph. Notes added 19 Feb 2022: This individual was initially reported by Bob Adamo and was an early example of a yellow-legged variant of a locally common species causing identification confusion. Pat and I made a point of studying this bird in life and obtaining photos documenting its typical-for-GBBG wingtip pattern. We have also aggregated documentation of the scarce but regular occurrence of yellow-legged variants (and other kinds of variants) among GBBG and HERG on Long island: https://flic.kr/s/aHskRoYoSA Regarding the present individual, I posted an email to the NYSBirds listserv on 9 Feb 2009. The following is directly copied from this message, including the various dead links, but with the discussion of rare geese in western Suffolk at the end excised: "The date we visited Iron Pier was actually Saturday, 7 Feb 09. -----Original Message----- From: Shaibal Mitra mitra@mail.csi.cuny.edu Sent 2/9/2009 8:52:40 PM To: shaibal mitra mitra@mail.csi.cuny.edu, NYSBIRDS-L@cornell.edu Cc: jtrimble@oeb.harvard.edu, D'Anna, Willie dannapotter@roadrunner.com, Hugh McGuinness hmcguinness@ross.org, davehawkowl@msn.com, birderbf@yahoo.com, fresha2411@aol.com Subject: Re: Photos of Iron Pier Gull, plus Barnacle and GWF Geese, Suffolk On 6 Feb, Pat Lindsay and I enjoyed intimate views of the yellow-legged Great Black-backed Gulls at Iron Pier, Northville, Long Island. Despite some people's impressions of the first set of photos, this bird has genuinely yellow legs, although the feet show an orangey mix of yellow and pink. Photos showing the wingtip pattern (and a Vertebrate Zoology ID Quiz) are posted at the end of the album at: http://picasaweb.google.com/tixbirdz/GreatBlackBackedGullsWithYellowLegs# hint: as expected, the delectable Vert belongs to the Osteichthyes, but it belonged to a more derived lineage than I initially expected. We also communed with two Iceland Gulls and a Lesser Black-backed Gull, depicted at the end of the album at: http://picasaweb.google.com/tixbirdz/Various2009# Shai Mitra Bay Shore, NY -----Original Message----- From: Shaibal Mitra mitra@mail.csi.cuny.edu Sent 2/6/2009 4:05:44 PM To: NYSBIRDS-L@cornell.edu Cc: jtrimble@oeb.harvard.edu, D'Anna, Willie dannapotter@roadrunner.com, Hugh McGuinness hmcguinness@ross.org, davehawkowl@msn.com, birderbf@yahoo.com, fresha2411@aol.com Subject: Photos of Iron Pier Gull, plus Barnacle and GWF Geese, Suffolk Bob Adamo has graciously permitted me to post some of his photos of the Iron Pier, Suffolk County, mystery gull in an album on my Picasa site. I cropped several of the photos but resisted the urge to correct the exposures, given the potential impact this could have on color tones, and I'm not completely sure that the two underexposed photos show the same mystery bird. In my opinion, the bird appears to be a Great Black-backed Gull (Larus marinus) with yellow legs—an unusual, but far from rare, condition. On Long Island, I recall a locally famous example of this sort from Pt. Lookout, Nassau County, about a decade ago, that was referred to in those early years of email debates as a "Kelpish" Gull. I also managed to dig up photos of my own of an orange-legged marinus from Jones Beach, 8 Jan 06, which I've included in the album with Bob's photos. The bird's dusky iris, red orbital ring, and narrow tertial crescent readily exclude Yellow-footed Gul (L. livens). I was rooting for Kelp Gull (L. dominicanus), but the dusky iris, extensive white on the outer primaries, and very large size argue against this also. I've included a photo of a Patagonian Kelp Gull by Jarrod Santora, from Punta Arenas, Chile, on 8 Jan 03, in the same album with those of the mystery bird"
