Interspecific kleptoparasitism, or the stealing of food from other species, is fairly widespread among birds, most frequently reported for seabirds, especially among the Charadriiformes (Brockman and Barnard 1979, Furness 1987, Iyengar 2008). Though most kleptoparasitic species engage in this behavior facultatively, some (especially within the Charadriiformes) may be obligate kleptoparasites during a particular season and potentially throughout the year (Iyengar 2008). Within the family Pelecanidae it has been infrequently reported in the literature.
