On 7 February 2003, during a fish survey in the Ojo de Agua at Río La Purísima, about 20 km upstream of Carambuche, Baja California Sur (26° 19′ 24.2″ N, 111° 59′ 09.7″ W, altitude 195 m), I observed and photographed a Neotropic Cormorant (Phalacrocorax brasilianus) resting on a small island in the center of the river (Figure 1). A day later, this same individual was found dead in a gill net placed in the river, along with 12 exotic cichlid fish (Tilapia cf. zillii). The bodies of two of the fish were mutilated, indicating that the cormorant had attempted to feed on them. The collected specimen, an adult male (total length 720 mm; wing span 960 mm; weight 1305 g), was deposited in the Bird Collection of the Facultad de Ciencias, Universidad Autónoma de Baja California, at Ensenada (UABC-1321, Figure 2). This individual constitutes the first known specimen of this species for the Baja California Peninsula.
