Thanks for looking.
Could be. It looks like there is quite a bit of color variation - even a white form in Florida. Ours are mostly a blue-grey and more dark grey than blue. They have some white on their head and wings, but are really fairly dark.jamesmck wrote:Thanks, Nathan. I wonder if time of year rather than geographical location might explain color differences. Do you mean that the blue/gray parts are darker but the white is still white?
Thanks for the link. Mine clearly have more white on the neck and chest. I looked at some older pics taken in the fall last year and the color scheme is pretty much the same as my recent July photos, so time of year does not seem to matter.OpenWater wrote:Could be.
