Western Gull 1+1 ? - Tsawwassen Ferry Terminal, Vancouver - 1st July (1 Viewer)

Hi all.

I understand that Western is scarce here at this time of year, but these look like good candidates for a ‘pure birds’ Ideas please. If not please explain so I can learn something!

Thanks Keith

For the first adult bird, and perhaps the second, the primary tips are not as dark as I would expect for a pure Western Gull. I would guess it to be mostly Western, with some Glaucus-winged genes. I will not guess on the juveniles.

The juvenile does not look like a pure Western to me with the even colored wings and wingtips. I agree with hybrid for the first bird.

Thanks very much for the very useful information.
