Herring Gull of the nominate race Larus argentatus argentatus

An adult Herring Gull of the nominate race Larus argentatus argentatus on Hastings Old Town boating lake late morning today.

Diagnosis;-

Perched on dry island alongside argenteus immatures and adults. Bird noted because of more leaden grey mantle and wing coverts and long-bodied appearance. Thick grey mottling on head and around eye and especially densely mottled at base of nape/uppermost mantle.
In water more erect carriage, especially head held up but also longer-bodied and of note;- length between tip of scapulars and tip of tertials greater on closed wing than the same feature on adult argenteus.
Bill somewhat stouter with whiteish lime-lemon basal two thirds.
Outer primaries markedly white-marked. The tips large and also with a white trail forming a row of white ‘d’ markings isolating some of the black primary tips.
Base of extensive white scapular area cleanly demarcated from grey remainder.
