Blue-winged Teal can have bright red eyes (see photos on Birds-eye App). Looks good for BWTE x northern shoveler.

I've never seen a cinnamon teal with a crescent on its face. I would go towards blue winged teal.

I agree with Michael...

The red eye also leads me to think that Cinnamon Teal is in the mix somewhere. Shovelers have yellow eyes and Blue Winged Teal have black eyes, so I don't see where else the red eye could come from. Also, Blue-winged Teal x Shoveler hybrids normally don't have rusty flanks. I would call it a Cinnamon Teal x Northern Shoveler hybrid, but that's just my opinion. I have no idea whether it's possible for all three species to be a part of this birds background.

I love hybrids - thanks for the photo!

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...
