Mark F Posted April 11, 2020 Share Posted April 11, 2020 This bird was seen a few days ago by San Francisco Bay. I think it's "just" a Herring Gull, but I'd appreciate your input. Thanks! 2 Quote Link to comment Share on other sites More sharing options...
blackburnian Posted April 12, 2020 Share Posted April 12, 2020 I believe this is a Western Gull with that dark mantle. 1 Quote Link to comment Share on other sites More sharing options...
Connor Cochrane Posted April 12, 2020 Share Posted April 12, 2020 (edited) This looks like a Western Gull. It's the most common gull in the bay, compared to Herrings, which are relatively uncommon. Note the dark color of the back, which would be much lighter in a herring gull. Bill shape is much different from herring, and herring's usually have streaked heads during this time.
