A series of shots taken of a second winter/third calendar year Caspian Gull on the Hayle estuary over the last couple days.

 Second winter/third calendar year Caspian Gull , Hayle estuary,thanks for the help and advice on clinching this birds identity.

 Was,nt sure about this birds identity until i saw  it in flight yesterday ,here it shows all the relevant features including a  small white mirror on p10 ,pale underwing with small dark spotting and a clean headed look with dark beady eye among other things.

 Not a very beaky looking Caspian ,but still a reasonably slim evenly paralleled bill.

 Note the neat hind neck streaking against the gleaming white head and the slim longish pale legs,although not the longest looking legged Caspian i,ve seen..
