Corys coming at you. There are some in Europe that are promoting splitting Corys.Underwing pattern (white tongues up primaries)suggests Scopolis according to literature - bill size and shape suggests otherwise.

Corys Shearwater, early July, Cape May.Corys off N.C.in early august were all 'blunt'winged and in wing molt.

The warm tones to the upperparts and large broad based bill make this a Corys.

July 15 - the very fresh looking appearance is surprising to me as this appears to be a Ccrys (not Scopolis)and yet only a month later they seem very worn and in heavy wing molt.

Corys (Scopolis?)Shearwater underwing. Cape May 7/05. Scopolis average smaller,wings are more pointed, bill is more slender and duller yellow.Molt timing possibly earlier.What is this? I wouldn't put too much faith in underwing pattern!
