1 cy Yellow-legged Gulls Larus michahellis: a sample of July birds from NE Spain

This post shows a sample of 1 cy michahellis, all photographed on the beach at Roses (a small resort near Girona, Catalonia, NE Spain) on the same day. They nicely illustrate variation in the plumage and structure of michahellis at this time (25 July, 2010). In another month when wear and moult have set in, these birds will be very easy to identify; but on this date many are, in my opinion, rather difficult to seperate from some Herring and some Lesser Black-backed Gulls. The post which follows shows the same sample of birds in flight.




In some ways this bird is a little reminiscent of cachinnans (it is rather gangly and has very simply patterned greater covs)

Note how weak-billed some young 1 cys can be.

Very simple fringes on all feathers, including gtr covs.























A bird with extensively pale feather patterns


1 cy Yellow-legged Gulls, Roses, Catalonia, Spain: birds in flight

Here are flight photos of the same birds at Roses (all taken 25 July 2010). The aim is to illustrate variability in the feather patterns on the tail, inner primaries and underwing.
