One (1979-15) in first alternate plumage on 2 Jun 1979, St. Bernard: Breton NWR, Chandeleur Islands, Curlew Island; Lawrence O’Meallie (ph). Shortly after the observation, the observer submitted the photograph to LSUMNS for identification. The bird was erroneously identified as a Bonaparte’s Gull and the slides were filed. The photographs were eventually reevaluated and submitted to the Committee (by Dittmann) as a Sabine’s Gull. This becomes the first state record supported by hard documentation.
