This morning at 10:30 there was a hybrid duck in the big NW pond at Cottonwood Hollow, the pond with the bench and interpretive sign overlooking it. I added photos to my eBird checklist: https://ebird.org/view/checklist/S54174768.
-- This is probably a common hybrid but I know next to nothing about hybrids. It seems to me that we (birders) just assume that if a bird has familiar traits of two species, it must be a hybrid of those two species. But this individual has traits (I think) of Northern Shoveler, Cinnamon Teal, and Blue-winged Teal. I'd be very appreciative if somebody could explain, offline if necessary, why it is in fact an AxB and not an AxC or BxC. Or perhaps it is unidentifiable. If I knew the answer I wouldn't be asking...
