The ACAP-listed Northern Giant Petrel Macronectes halli has been included in the Sixty-third Supplement to the Check-list of North American Birds, a publication of the American Ornithological Society. The supplement has been published in the journal, Ornithology. The inclusion of the Northern Giant Petrel is owing to its sighting by a fisherman off the coast of Ocean Park, Washington, U.S.A. 

First published in 1886, the Check-list is compiled by the AOS’s North American Classification Committee (NACC), the official authority on the names and classification of the region’s birds and is updated every summer.
