Left bird with the dark back
观察细节
Estimate ~1% of birds in the Aythya mass. Some birds stood out as being particularly dark-backed, such as the individual photographed below. We entertained a hybrid option for these individuals, but once they stuck their head out, they looked like pure Greater Scaup save for the extreme dark back, though still not approaching the darkness as on the Greater Scaup hybrids in the flock. We probably saw five individuals like this.
