Thermalito Afterbay Western Gulls


Bruce Deuel
 

To all who went to see the first Butte County Western Gull at the Afterbay, there are, or were, 2 birds there. If you saw the one with the bright yellow bill with nice red spot on the mandible and the nearly clean white head, you're safe. If, like I did, you saw the one with the black ring near the tip of the pale yellow bill and the dusky markings on the head, experts have concluded it's a hybrid. I will be marking any eBird reports of that bird as unconfirmed as a Western Gull.
