Bowers Marsh: Stilts, Black-necked Grebes, and a probable Glaucous Gull
The pair of Black-winged Stilts were still present on the main freshwater lagoon at Bowers Marsh today. Also present on the lagoon were two Black-necked Grebe.
Amongst the roosting gulls (somewhat separate from them at first) was what I took to be a 1st winter Glaucous Gull. Always wary of hybrids, I'll give a brief description here (sorry it is lacking in some important points, such as primary projection) and Steve Arlow or others might have the local knowledge to point out possible pitfalls for identification (e.g. is there a hybrid around this area that has previously been misidentified?) It was a large gull, probably larger that the nearby Herring Gulls. The overall plumage was light grey-brown, but the primaries were pale – whitish grey/creamy coloured – which showed much paler than the secondaries in flight. The bill was large and its colour was two-thirds flesh/pink coloured with a marked black tip. Save for the pale primaries, the bill colour was the clearest distinguishing feature, and it made me opt for probable Glaucous Gull.
Any help is welcomed.
