RIBEIRO, Leonardo Barros; GOMES DE LIMA, Daniela  and  FONSECA DE MELO, Silvia Beatriz. Competitive interaction of Coragyps atratus (Bechstein, 1793) (Cathartiformes, Cathartidae) in the use of a limited resource. Rev. etol. [online]. 2010, vol.9, n.2, pp. 34-39. ISSN 1517-2805.

The interaction and space use among the specimens of Black Vultures (C. atratus) consuming a limited resource in the form of a temporary water source, during drought period, at one site in northeastern Brazil is described. The birds showed an aggressiveness frequency elevated by the increase of the number of individuals accomplishing behavior of drinking water, and a distribution of the individuals apparently hierarchic in the access to the resource.
