|Adult Caspian Gull, Shawell A5 Lagoons, 07/01/15, (2015.6)|
The longest primary P10 was still growing and was just slightly shorter than P9, so it will look even longer winged in the near future. This one was quite large so most probably a male. The image above is quite typical of Caspian Gulls on the bank as they all seem to be quite sleepy when resting on it.
|Third-winter Caspian Gull, Shawell A5 Lagoons, 07/01/15 (2015.5)|
The third-winter had noticeably long legs, but in the photo above a bit of each leg is hidden by the grass. Its bill has a bit of a droop to it, but its length against depth ratio fits the norm for Caspian Gull. Defining where to drawn the line between pure and hybrid with this species is very complex as at times different experienced observers will have conflicting opinions.
