Gull haul

Met up with Josh Jones today to have a look at the Beddington Gulls. A pretty good haul; the pale morph juvenile/first-winter Glaucous Gull, the first-winter Iceland Gull, a first winter Caspian Gull, an adult Mediterranean Gull and a presumed adult Yellow-legged Gull.

 The striking juvenile/first-winter Glaucous Gull. The bird is easily the size of a Great Black-backed Gull and the barring on the undertail coverts and pink based bill with a black dipped in ink tip exclude the possibility of a leucistic GBB. Pale morphs like this are more typically in Nearctic populations of Glaucous Gull- could quite conceivably be a bird from Greenland considering that's the minimum distance that Iceland Gulls are coming from.
