Cardiff and Donna L. Dittmann; NASFN 49(2): 156, LOS News 164: 6. Mainly as a result of better pelagic coverage during the 1990s, this species is now considered regular in fall, winter, and spring, with smaller numbers of coastal and pelagic records from the summer months and from inland bodies of water during the fall; it was removed from the Review List in September 1996.

Unaccepted Records

One light morph sub-adult (89-73) on 10 Jan. 1989, Cameron: 2 mi. west of Holly Beach. All members believed that this record probably did pertain to this species, but the description of the plumage, size, and flight behavior noted by the observer did not sufficiently rule out Parasitic Jaeger (S. parasiticus). Identification of jaegers is more complex than the observer indicated. This record was reported as an unidentified jaeger in AB 43(2):326.

One in immature plumage (1994-78) on 18 Dec 1994, Cameron: Johnsons Bayou Beach; NASFN49(2):157. Although Pomarine is the expected jaeger species at this locality and time of year, diagnostic plumage details were not clearly observed.
