A small number of gulls out on my sandbar today. Thanks to a strong cold front it got cut off to vehicles, meaning no fishermen!

The first photo contains four adult and three first-winter taimyrensis. Hard to see in the photo, but all the first-winters are all actively replacing their greater coverts with rather solid greyish feathers. This is easier to see in flight (second photo). The bird sitting in the centre is an adult vegae, and a further adult is obscured in the background.

A first-winter Slaty-backed Gull also flew past offshore, as did an unidentified first-winter. Before, I would have called this a taimyrensis, but I am now confused as to why it is not replacing its greater coverts and why its scapulars have been replaced with feathers of a patterned 'first-winter' type.

Is the flying adult a vega? Look at those prominent pale tongues with wide white tips
