Itens alimentares encontrados em amostras de regurgitação de Pyriglena leucoptera (Vieillot) (Aves, Thamnophilidae) em uma floresta secundária no Estado do Rio de Janeiro

The diet of P. leucoptera (Vieillot, 1818) was studied using the emetic tartar which induces birds' regurgitation. Birds were captured and treated between May 1996 and June 1997 in the Atlantic Forest at the city of Guapimirim, State of Rio de Janeiro, southeastern Brazil. The study area is a secondary forest continuous to the Serra dos Orgaos forest. Insect fragments of Coleoptera and Hymenoptera were the items most frequently found in the regurgitate samples. Besides contributing to the knowledge of the species diet, pictures of identified Arthropoda fragments are presented in order to aid future works on avian feeding.
