Greetings All
I thought I'd posted to COBIRDS about this, and if I have, I apologize for the duplication. It may have been Frontiers of ID. In any case, Great Black-backed x Herring Gull numbers are increasing, mostly in the Midwest as GBB Gull expands its range into the Great Lakes. What I don't like about the Pueblo bird, vis a vis, Slaty-backed Gull is the huge bill and the apparent medium dark (not blackish) mantle. Also, most SB Gulls show some smudging around the eye. So, I guess no one mark from the photos could rule out SB Gull, but it reminds me much of the GBB x Herring Gull hybrid pics I've seen, and the few responses on Frontiers seemed to suggest GBB x Herring Gull as most likely. Cool Bird Gulls, Fun and Torture, all wrapped up into one. >From Los Barriles, Baja California Sur Where hybrid gulls are NOT a problem.
