Yellow-legged Gull - what took you so long?

13th August 2016 - Topsham


Less than satisfactory photos. I'm afraid, but here's my first juvenile michahellis of 2016. A fairly typical bird and not one of the monsters that occasionally turn up. It can be difficult to convey just how straightforward these things can be; you can describe finer points of structure, of tertial edges and tail patterns or degrees of wear and moult and yet sometimes it just comes down to an immediate impression: it just looks like one. (I should also admit that they can sometimes be very tricky, variation within LWHG taxa can be astonishing and that's not even starting on hybrids!)

 Pretty much my first view and really all you need to id it.

 Long wings, long legs, deepish bill and square head.

 White head with dark eye patch, quite well-marked flanks.

 Simple fringes to tertials (only tips) wing coverts and scapulars - not much barring or notching. Much more worn than juv HG or LBBG with obvious moult in scaps.

 It spent most of it's time doing this, shuffling a few metres when the tide rose.

 Whitish tail base with a few large blackish spots and a neat black tail band.

White upper TC and tail very white at sides (a little over exposed I admit).
