Proposal (711) to South American Classification Committee

Add Pterodroma nigripennis (Black-winged Petrel) to the main list

One Pterodroma nigripennis was photographed on 17 Apr. 2014, 177 miles N of the Desventurada Islands (San Felix and San Ambrosio), Chile, by Stephen Copsey (Barros & Schmitt 2015). One photo of this individual can be seen in the website below. Two photos were published in Barros & Schmitt (2015). The bird clearly shows the Cook’s Petrel like upper side, and bold black ulnar bar on the underwing as well as the shape of a “Cookilaria” rather than lankier Pterodroma.
