Predation of Platyrrhinus lineatus (E. Geoffroy, 1810) (Chiroptera: Phyllostomidae) by Cyanocorax chrysops (Vieillot, 1818) (Passeriformes: Corvidae)

The predation on vertebrates by birds, including bats, is very common in some families (Accipitridae, Falconidae, Tytonidae, Strigidae), constituting their main diet. For other families (except those that feed strictly on fish), it is occasional and sometimes a matter of opportunity. Here we recorded the predation on a bat (Platyrrhinus lineatus) by the neotropical bird plush-crested jay (Cyanocorax chrysops). On July 26, 2009, around 11:00 am, we recorded an individual of C. chrysops taking part of a P. lineatus on its beak. This record occurred on Jacarezinho Farm (Valparaiso SP). The prey species identification was done by visual observation, considering the bat size and its external morphology, especially by the presence of the white dorsal bright stripe. Probably, Platyrrhinus lineatus behavior, which involves living together or in couples on tree canopies, made the capture by the plush-crested jay easier. This is a new record for the diet of C. chrysops and highlights the necessity of additional studies related to birds diet in the Neotropics, even the more conspicuous ones.
