RE: [cayugabirds-l] Seneca Lake Tufted duck and Aythya hybrids

If it matters the Seneca Yacht Club is different than the Geneva Boat and Beach 
Club. The Yacht Club is off 96a at the mouth of the Seneca Canal across from 
the far end of the state park and the Boat and Beach Club is I'm guessing 3 
miles south of Geneva on 14 on the west side of the lake. Excellent sightings.

Tufted earlier in the morning, I came across a nice variety of Aythya hybrids

RING-NECKED DUCK x SCAUP SP. HYBRID in the large flock off the middle of Seneca 
Lake State Park. I didn't get a photo, but it looked likely to be the same bird 
that had been in the flocks on the west side of the lake. Some poor photos of 
that bird from two weeks ago

end of the Geneva Lakefront Park area, the smaller Aythya flock close to shore 
contained a REDHEAD x SCAUP SP. HYBRID, a REDHEAD x RING-NECKED DUCK HYBRID, 
and most notably, an apparent CANVASBACK x REDHEAD HYBRID that Tim had noticed 
earlier. This cross is one of the tougher to pick out in my experience, looking 
mostly like a dingy Canvasback at first glance. The headshape is indeed 
intermediate between the two species, but with a sloping enough forehead it 
doesn't immediately stand out as not being a Canvasback. On this individual, 
the blue markings on the bill are perhaps the most noticeable feature, along 
with overall slightly grayer body color. The eye is also subtly more orange 
than Canvasbacks, although still much darker red than Redhead. They always 
recall Common Pochard, but the bill pattern is usually distinctly 
different.Photos of these three hybrids

still have a decent sized Aythya flock in the southwest corner of the lake, but 
the only birds of note there lately have been two more REDHEAD x SCAUP SP. 
HYBRIDS. Photos of both (nearly identical) individuals

[cayugabirds-l] Seneca Lake Tufted duck and Aythya hybrids
