Herring X
Great
Black-backed
Gull
Fig 1) This bird is a presumed hybrid, although it comes from
California, where Great Black-backed is unrecorded. Nevertheless, this
bird matched all descriptions in the literature of Herring x Great Black-backed. It was in the company of Western Gulls for an interesting
comparison. In the uppermost photo, that's a Western on the left and the
bird in question on the right. Van Damme State Beach, Feb 6, 1997.
