Unaccepted Records

One male (1992-051) on 6 June 1992, Lafourche: Port Fourchon, w. end of Theriot Rd. off Fourchon Rd. Following three circulations, a majority of Members believed that the reported size was inconsistent with a Shiny Cowbird (too large), and details on other characters were too vague for acceptance.

One male and one female (1992-62) on 25 Oct 1992, Cameron: 1/2 mi. N of Peveto Beach Woods. The observer�s description did not include color of the male's glossy plumage, shape/proportions, or length. Additionally, the bird was noted as having a "finch-like" bill and "longer neck feathers," which did not seem consistent with this species and were somewhat more indicative of Bronzed Cowbird.

One male (1998-037) on 25 May 1998, Jefferson: Grand Isle, Sureway Woods. Following two circulations, most Members believed that the identification, although possibly correct, did not cross the threshold for acceptance, mainly because of brief views and the resulting superficial description.

One adult male (1999-030) on 16 April 1999, Jefferson: Grand Isle, Bobby Santini�s yard. This report went to a Discussion vote at the 2015 Annual Meeting but was inadvertently not included in the 18th Report of the LBRC. Three Members believed that the documentation provided did not adequately support acceptance.

One male in breeding plumage (1999-105) on 28 April 1999, Cameron: Hwy. 82 ferry landing on W. side of Calcasieu River. The photos provided did not seem to exclude a first-year male Red-winged Blackbird from consideration.

One adult male (2000-026) on 15 April 2000, Jefferson: Grand Isle. This record went to Discussion Round vote where all Members agreed that the brief description, although provided by an experienced observer, did not support identification of this species.

Two, a male and female (2000-034), on 3 May 2000, Jefferson: Grand Isle. Nearly all Members believed that the description was more indicative of a Bronzed Cowbird.

One adult male (2003-025) on 30 April 2003, Orleans: New Orleans, 2201 Lakeshore Dr., Information Technology Center. Acceptance was problematic because the observer expressed some doubt about the identification and did not get a clear view of all characters.

One adult male (2006-006) on 30 April 2006, Jefferson: Grand Isle, end of SR 548 between Hector Ln. and Cemetery Ln. Most members believed that the details provided were insufficient.

One adult male (2006-048) on 23 December 2006, Grant: Kateland Plantation Rd, ca 0.25 mi. E intersection Hwy. 8 between Boyce and Colfax. Details were considered unconvincing, especially for an inland winter occurrence.

One adult male and female (2007-41) on 20 May 2007, Jefferson: Grand Isle, two blocks east of water tower. Although reported from a location where this species has been somewhat regular, the description was not adequate to eliminate Brown-headed Cowbird. Additionally, there remains no accepted record to date of a female Shiny Cowbird.

One male (2018-069) on 10 November 2018, Jefferson: Grand Isle, TNC Grilletta Tract parking lot; (ph). All Members agreed that the photographs did not support identification of this species because Bronzed Cowbird was not satisfactorily eliminated.

One male (2019-034) on 11 July 2019, St. Tammany: Big Branch NWR, Lake Road, N30.271311o, W89.961450o (ph). Most Members agreed that the photos were of insufficient resolution and that the description was relatively superficial.

One adult male (2021-057) on 10 July 2021, Jefferson: Grand Isle, less than 0.25 mi. E Hwy. 1 & Humble Rd.. Most Members agreed that the description did not rule out Red-winged Blackbird.
