More images of the Argyll ‘Thayers’ type Gull

From Bill Allan:

“The putative juvenile Thayer’s gull dropped into Dunbeg bay on Tuesday Jan 17th at 14.20 and was still there at 16.00 hours.(1st sighting for 3 weeks but minimal coverage of site)

There have been some negative comments re the tertials being “too pale”…..would have thought the main point is that the tertials contrast with darker primaries as opposed to Kumlien’s gull where the opposite applies or they will be described as concolourous.The tertials look fine to me (dark centred.)

Some pics with other gulls to get some idea of biometrics.”
