PETRACCI, Pablo F.; CEREGHETTI, Joaquín; MARTIN, Julieta  and  OBED, Yamila S.. Spring diet of the Neotropic Cormorant (Phalacrocorax olivaceus) in the Bahía Blanca estuary, Buenos Aires, Argentina. Hornero [online]. 2009, vol.24, n.2, pp.73-78. ISSN 0073-3407.

The spring diet of the Neotropic Cormorant (Phalacrocorax olivaceus) in a coastal marine environment is described. This species is widely distributed in Argentina and their trophic habits have been scarcely studied. Paradoxically, in 1981 it was declared a "harmful species" in Buenos Aires Province. A total of 200 pellets from adults and juveniles were collected during four visits between 2003 and 2006 in the del Puerto Island, Bahía Blanca estuary, Buenos Aires Province, Argentina. A total of 15 prey items were recorded, with teleosts fishes as the most important items in the diet. The lucerna (Porichthys porosissimus), a benthic toadfish with no commercial value in this zone, was the most frequent prey.

Keywords : Bahía Blanca; Diet; Estuary; Neotropic Cormorant; Phalacrocorax olivaceus.
