Hello all,
can I get confirmation that this is in fact a first winter Lesser Black-backed Gull? Most of the features look good for one – short, all-black bill, rounded head, long wings, mottled pattern of the wing coverts – but it seems to me that there's rather a lot of white on the tertials for an LBBG. Seen in Lake Ontario, off Toronto two days ago.
