Accepted Records

One (1971-02; formerly 85-37) on the Mississippi River at New Orleans, Orleans/Jefferson Parish, from 3-6 November 1971 (DP,MM*). This bird was photographed, and a photo published in American Birds (Purrington 1972:74). This was the first record of any kind of "Western Grebe" for Louisiana and was accepted by Lowery (1974). The American Ornithologists' Union "Checklist Committee" recently (AOU 1985: 680-681) recognized as a species the very similar Clark's Grebe (A. clarkii), formerly regarded as merely a color phase of the Western Grebe. This change in nomenclature requires that the Committee will review all previous Louisiana records of "Western" Grebe to ascertain to which species they in fact refer. The Committee has accepted the original 1971 record as a true Western Grebe.

Two birds (1981-09; formerly 82-39) on the Gulf 2-3 miles west of Holly Beach, Cameron Parish on 25 January 1981 (JK*), with one bird still present from 14-22 February 1981 (VR; MR,BC.PO,DH).

Unaccepted Records

One (1997-012) on 25 January 1995, Union: D’Arbonne NWR. The description did not provide enough detail to accept to species. However, some Members maintained that details submitted were good enough to document the genus Aechmophorus. So, this record continued through a Third Circulation before a majority of members agreed that the description was just too vague to support the observation as even a generic Western/Clark’s Grebe.

Three (1995-150) on 23 Dec 1995, St. Bernard: 2 mi. NNE Arabi. The description did not eliminate Clark's Grebe. Additionally, some members expressed concern that the grebes may have not been Aechmophorus, but instead Podiceps, because only Horned Grebes were subsequently relocated at the site.
