This emaculate Caspian Gull has an unusually bright bill, showing neither the usual limy tone to the base nor a black mark on the gonys, and obviously yellow legs. One would only expect to see these things when breeding.

1st winter Common Gull, Milton, 29th January 2007, © Dick Newell
Most nominate canus Common Gulls should have moulted their scapulars by late September but this bird has barely started. This is more typical of birds from a more northerly or easterly origin. Together with the primaries hanging below the tertials and inner greater coverts this bird could be heinei. See this Danish example of a November heinei. (RGN)

Fairly large bird, so probably a male. Unusually, the underwing was rather dark for a Caspian Gull, which, together with the fairly heavily anchored scapulars, perhaps indicates some impurity. (RGN)

Almost certainly the same bird (Jamie's picture was taken a few days earlier), there are enough clues here for a conclusive id, including greenish bill-colour and shape, beady eye, darker than Herring Gull, long legs, upright stance, long neck, what more do you need?

Although not usually exposed, and, although illustrated in a video-clip but not even mentioned in BWPi, white bases to the scapulars is within the normal variation of Sparrowhawks, as in this similar Polish bird. The width of the top of the garden seat is 70mm, from which one can work out a very approximate wing-length of 184mm, which is even smaller than the smallest male Sparrowhawk. So this bird is almost certainly a male. [RGN]

1st Winter Black-headed Gull, Fen Drayton, 14th January, © Stuart Elsom. The recently flooded fields at Fen Drayton are proving a magnet for feeding Black-headed Gulls, with some individuals like this moulting first-winter bird dip feeding right by the roadside. (SME).

Long-tailed Tit is just about annual in Stuart's garden so a flock of
12 so soon into the New year was very welcome indeed. This endearing
individual was just about the only bird in the flock to stay still long
enough to allow its photo to be taken!

Yellow-legged Gull ssp., Long Drove, Cottenham. 5th January 2007
This 3rd winter bird is extremely dark for a nominate michahellis, so one might consider Armenian Gull, Azorean atlantis or a hybrid. Azorean gull has probably lost its head-streaking by now, so that doesn't help. Given the numbers of Caspian Gulls about, one is tempted to think of something from the east. The illustration of a 3rd winter Armenian Gull in BWPi looks a very good match. (RGN)
Feedback: This bird resembles a ringed hybrid Yellow-legged x Lesser Black-backed Gull seen by Steve Cooper a few years ago.
