American Herring Gull 7359 (Larus smithsonianus)

Kuvaus:

Description: English: Location: Delta-Mendota Canal at Gaffery Rd., Stanislaus County, California. Adult. Note yellow-orange orbital ring. I treat this taxon as a legitimate species, not as a subspecies of Larus argentatus. A great deal of molecular data supports this view, and runs contrary to ebird. Date: 4 December 2016, 12:25:01.
