Hi everyone. I was recently in Colorado for the Ross's Gull and I observed a flock of ~100 California Gulls at Cherry Creek.
My question is two-part: 1) What is the status of California Gull in Colorado? 2) What is the expected subspecies, californicus or albertaensis, and does this change according to season? I've observed large assemblages of this species in California twice this year, once in the winter and once in the summer. I must say, the Colorado birds showed greater variation in body size and primary pattern and I was wondering if the Denver area is perhaps a contact zone for both races. I do have photos and a video if anyone is interested. Any information would be much appreciated.
