Unaccepted Records

One (1989-37) on 2 Jan. 1989, Lafourche: east end Fourchon Beach (AB 43(4):982). The bird was observed under poor viewing conditions: very distant, fog, and poor lighting. The descriptions submitted by the observers did not eliminate the possibility that the bird may have been an immature Northern Gannet (Morus bassanus). Immature plumages of Northern Gannet can superficially resemble those of Brown Booby, and the two may not be separable under such poor viewing conditions.

One second-year (1999-042) on 14 April 1999, Gulf of Mexico: Ewing Bank 826-A oil platform, 61 mi. S of East Timbalier Island, N 28.16333o, W 90.35861o. Most Members ultimately agreed that details provided were insufficient to eliminate immature Red-footed Booby, Masked Booby, or even Northern Gannet.
