Scopoli's Shearwater (Calonectris diomedea) - 11Jun, 22&27Aug2022

Scopoli's Shearwater is the result of a recent split from Cory's Shearwater.  Both are present in the North Carolina Gulf Stream, with numbers fluctuating depending on breeding and molting schedules.   The Scopoli's Shearwater has some subtle differences with maybe some of the birds are best left unidentified.  The main field mark is amount of white extending into the bird's "hands" which are just the outermost primary feathers including P9 and P10.
