Associating with two western grebes. White above eye with "carrot orange" bill.
I have some reason to think this might be a Clark's/Western hybrid, such as the rather muted bill color

Clark's Grebe, group of about 20 birds on central part of large inlet on southern part of Don Pedro near Highway 132
Actually, I wonder if this is a hybrid

Clark's Grebe (Aechmophorus clarkii) is a North American species in the grebe family. Until the 1980s, it was thought to be a pale morph of the Western Grebe, which it resembles in size, range, and behavior. Intermediates between the two species are known.
