White-winged Gull on Ware Tip


A juvenile KUMLIEN'S GULL (or just possibly a Kumlien's/Thayer's intergrade/hybrid) was present on Westmill tip, Ware this afternoon from 14.45 until 15.40 when it flew off South.

The plumage was typical of a "dark end" Kumlien's (I have found numerous Kumlien's photos with an exact match for the plumage that the bird was in), but it was structurally slightly heavier than a typical Iceland Gull - it had a rather oblong or "pear shaped" head more reminiscent of a Thayer's than an Iceland Gull - so far I have found only a few photos captioned as Kumlien's of birds with this sort of structure (Barry Reed)
