Pertaining to records 2012-115 through 2016-055: Regardless of the level of taxon each record was submitted as (e.g. identified to subspecies C. d. diomedea or C. d. borealis) all Cory’s Shearwaters accepted above are accepted only to the level of ‘Cory’s Shearwater complex,’ which may include Cape Verde Shearwater (C. edwardsi). The committee will re-address accepted specimen and photographic records at a later time when definitive information is available to more confidently identify these taxa. Specimens of both nominate diomedea and borealis have been obtained in Louisiana waters, but “intermediates” have also been reported in U.S. waters. For more information see Howell (2012) and Howell and Patteson (2008).

One (2018-061) on 22 September 2018, Gulf of Mexico: 24.5 mi. SE mouth of Southwest Pass of Mississippi River, N28.636o, W89.162 o; Erik I. Johnson (ph). Reportedly first spotted by Jack Rogers.
One (2018-062) on 22 September 2018, Gulf of Mexico: 30 mi. SE mouth of Southwest Pass of Mississippi River, N28.567 o, W89.114 o; Erik I. Johnson (ph) and Cameron L. Rutt (ph only).
One (2018-063) on 22 September 2018, Gulf of Mexico: 23.7 mi. SE mouth of Southwest Pass of Mississippi River, N28.621 o, W89.204 o; Erik I. Johnson (ph) and Cameron L. Rutt (ph only).
One (2018-080) on 22 September 2018, Gulf of Mexico: 22.0 mi. SE mouth of Southwest Pass of Mississippi River, N28.6424 o, W89.2537 o; Erik I Johnson (ph) and Cameron L. Rutt (ph).
Two (2019-072) on 17 August 2019, Gulf of Mexico: approximately 83 mi. SE Southwest Pass Mississippi River on Carnival Cruise ship Glory 8.17.19 Leg 23 of 25 at N27.762o, W88.924o; James F. Holmes.
One (1998-71) on 23 Aug 1998, Gulf of Mexico: 138 mi. S of Cameron, Garden Banks 189A oil platform, 27o46'43²N, 93o18'34²W. All but two members believed that the distance (1 ½ -2 ½ mi.) was too great, even with a 30X scope, to allow close enough study to observe necessary details to eliminate other species (especially Greater Shearwater) from consideration.
One (1998-70) on 27 Oct 1998, Gulf of Mexico: 61 mi. S of East Timbalier Island, Ewing Banks 826 oil platform, 28o09'48"N, 90o21'31"W. Although most members believed this report probably did involve this species, all but two indicated that details provided were insufficient.
One (1999-087) on 27 August 1999, Gulf of Mexico: 122 mi. S Morgan City, Green Canyon 18A oil platform, N 27.943611o,W 91.029167o. The bird was reported to have been over a mile away and seen only briefly, and the identification was largely based on flight style and general coloration. There was no discussion of wind conditions, which could have affected flight behavior. All Members were reluctant to accept the record because the identification was largely based on probability and other shearwater species could not be decisively eliminated.
One (2017-077) on 22 December 2017, Gulf of Mexico: open ocean, exact location unknown but somewhere north of N25.777590o, W89.869890o. Most Members were unwilling to accept this report without a specified location, and also were wary of a winter observation without photographic support.
