Itens alimentares encontrados em amostras de regurgitação de Pyriglena leucoptera (Vieillot) (Aves, Thamnophilidae) em uma floresta secundária no Estado do Rio de Janeiro Zoologia
Gomes,Verônica Souza da Mota; Alves,Vânia Soares; Ribeiro,José Ricardo Inácio.
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 Órgãos 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.

Territory size of three Antbirds (Aves, Passeriformes) in an Atlantic Forest fragment in southeastern Brazil Zoologia
Duca,Charles; Guerra,Tadeu J.; Marini,Miguel Â..
Territory size is an important ecological attribute of populations that has been considered a factor determines population density. Antbirds is a large group of mainly insectivorous Neotropical passerines, usually well represented in bird communities from forested landscapes in Neotropical region. Territory sizes for three Antbirds, Thamnophilus caerulescens (Vieillot, 1816) (Variable Antshrike), Dysithamnus mentalis (Temmink, 1823) (Plain Antvireo) e Pyriglena leucoptera (Vieillot, 1818) (White-shouldered Fire-eye), were mapped and their area estimated by the convex polygon method in a 50 ha forest fragment, in southeastern Brazil. The three species presented small territories of similar sizes (< 2 ha) both during the non-reproductive and the...
