Re: CG on a dump near the Minsk

From what I can see, it looks good for michahellis. JanJ Excuse me, colleagues. Birds like that sit now in hudreds on ice in centre of Minsk. I don't think it is michachellis as it has large white spots on primaries. Michahellis so far was not registered for Belarus. It's probably "omissus" type of...

Re: graellsii & intermedius?

how did you recognize it as the same bird, ryszard? apart from the outer rectrices which indeed look identic only bill shape may give a hint - looks similar also. but apart from that? still can be a dark herring gull i guess.

Re: Caspian or hybrid Caspian/Yellow-legged or ????

hello,

Re: 1st cycle Larus cachinnans

i think the original bird is a michahellis with a cachi-tail. covert pattern and head mask are very micha like as is the rest of the covert pattern with broad white fringes. hans' pics on svalan (see post only confirm my long felt suspicions. this is not a cachinnans: http://www.talk.gull-research.o...
