Edit - too many anomalies for 'cachinnans' - the more I look at these photos the more I think it's just a Lesser-black-backed Gull. The dark upper-wing and underwing certainly point strongly towards Lesser Black-back.
Inner primaries look slightly paler than outers but that underwing looks yuk. I didn't have the opportunity for a good flight view as the bird lifted rapidly and disappeared downriver into horrible light. Leeb?
Odd looking bird Matt - I think I would go with Lesser Black-backed too despite the paler inner primaries!ReplyDelete
Hi Matt, agree with LBB, don't see all that many March 2cy's so maybe they stand out?ReplyDelete

Thanks Mike, thanks Tim - tend to expect first yr Lesser Bbs to be darker above n below, with longer wings, so this one caught me out. Cheers. MattDelete
