Unaccepted Records

Parasitic Jaeger (Stercorarius parasiticus). (1981-05; was 82-16). A subadult 5 miles south of South Pass, Plaquemines Parish on 13 July 1981.

One dark phase adult (1985-49; was 86-24) on 8 Dec. 1985, Cameron: 2 mi. W OMMR (Muth 1986, p. 291). The observation was very brief and the description did not eliminate juvenile Long-tailed Jaeger.

One sub-adult or adult in basic plumage (1986-26) on 2 Feb. 1986, Cameron: 6 mi. W Holly Beach (Muth (1986, p. 291). The brevity of the observation and the viewing conditions precluded elimination of Longtailed Jaeger as a possibility.

One light morph in basic plumage (1987-12; was 89-127) on 4 Jan. 1987, Lafourche: off Fourchon Beach. This was a very brief sighting, about 45 seconds, as the jaeger harried a Laughing Gull and Forster’s Tern. The observer reported that there were no projecting central tail feathers and the bird’s age could not be determined from the observer's description. Estimation of size varied between the reporting observer and two other birders present. Because no definitive characters were observed, it is difficult to determine the identity of this bird and eliminate the possibility that it was not a Pomarine Jaeger, currently thought to be the more regularly occurring species.

One juvenile (1993-081B) on 18 December 1993, Cameron: 1 mi. SE Holly Beach. (See Accepted records). The original report included observations of an adult (previously accepted; see also 1993-081A) and a juvenile, but, ultimately, a majority of Members believed that details provided for the juvenile were not adequate to support its identification.

One dark morph juvenile (1994-43) on 4 Sep 1994, Plaquemines: 26 mi. NW of Venice. The Committee agreed that the bird was a jaeger sp., but neither the description of the bird, nor the photograph supported a definite identification of a member of this difficult-to-identify species complex.

One (1997-07) on 25 February 1997, Gulf of Mexico: 30 mi. SW of Port Fourchon, N 28.613889o, W 90.306944o. This record was accompanied by a very brief description that Members believed was not sufficient to rule out other jaeger species.

One dark morph immature (1997-57) on 24 May 1997, Gulf of Mexico: 47 mi. SSW of mouth Southwest Pass of Mississippi River, 28o14'N, 89o30'W, at 500 fathoms depth. This record was reported in FN51(4):882 as "photos suggest Louisiana’s 3rd Long-tailed Jaeger." This record received only one accept vote during the second circulation. Dissenting members agreed that the description and supporting photographs did not support identification as Parasitic, and at least two members believed that the bird was more likely a Long-tailed Jaeger. The record will be resubmitted as a Long-tailed Jaeger.

One subadult (1998-75) on 13 Sep 1998, Cameron: beach along Hwy. 82 near Holly Beach. Due to the identification challenge presented by this group, the Committee agreed that the description did not rule out other jaeger species.

One or two (2000-090) on 16 March 2000, Gulf of Mexico: South Pass 89B oil platform, approximately 91 mi. S of New Orleans, N 28.68044°, W 89.38578°. Although possibly correctly identified, the observer did not describe any plumage details and the identification was by size and “flight style.”

One second-year (2000-092) on 7 April 2000, Gulf of Mexico: South Pass 89B oil platform, approximately 91 mi. S of New Orleans, N 28.68044°, W 89.38578°. Possibly correctly identified, but the description did not adequately eliminate other jaeger species.

One dark morph (2006-042) on 3 December 2006, Cameron: East Jetty Beach. The bird was very distant and therefore Members believed that critical details could not be observed to confirm identification, especially of a rare dark morph individual.

One (2007-48) on 25 September 2007, Cameron: approximately ˝ mi. W of town of Holly Beach (ph). Photographs submitted were not sufficient to identify this individual to species and some Members believed it should remain a jaeger sp.

One subadult or adult (1994-172) on 18 December 1994, Cameron: gulf off Martin Beach (ABF card-only). This was another ABF card-only record without adequate details.

One immature (1994-170) on 21 December 1994, Cameron: gulf off Rutherford Beach (ABF card-only record). This was another record without adequate supporting details.
