Double-crested Cormorant (Phalacrocorax auritus) Science Article 9
abstract
Kleptoparasitism, or the stealing of resources, has been observed within and betweenmany bird species (Brockmann and Barnard 1979, Furness and Monaghan 1987).Although the kleptoparasite sometimes steals food without aggression towards the host,the host may be threatened or even attacked (Brockmann and Barnard 1979). In thisnote, I report a case of kleptoparasitism in which the host was violently attacked.
