Endangered bird species of one of the last remnants of lowland Atlantic Forest in Rio de Janeiro state, Brazil: pressures and preservation measures.

The lowland Atlantic Forest, at altitudes of below 500 m, is highly fragmented, and is home to many threatened species of birds. The Brazilian state of Rio de Janeiro has a high concentration of threatened birds in the Americas and is an important residual of the dense ombrophilous formations of the Atlantic Forest, which includes the Reserva Biológica União, a high priority area for conservation of Atlantic Forest birds. This study compiled empirical and secondary records of threatened birds in this reserve and discusses potential factors determining their local occurrence.

First evidence of frugivory in Myotis (Chiroptera, Vespertilionidae, Myotinae).

Background: Myotis occurs from tropical to temperate regions throughout the globe, and it is the largest bat genus with more than 100 species. Most species are insect-eaters, but a few also feed on other invertebrates and fishes; there is no confirmed evidence of a plant item in their diet.

New Information: During fieldwork in the Brazilian Atlantic Forest, small seeds were retrieved from the feces of one adult female of the Black Myotis, Myotis nigricans-one of the most common Neotropical bats.
