Habitat comments: "Atlantic Forest... secondary semideciduous forest and alluvial ombrophilous dense forest... The remnants are undergoing a natural restoration process after wood extraction 31 to 74 years ago... The areas are inserted in an anthropic matrix with fruit and sugarcane farming, as well as pastures and small farms"

Nets or traps: 10
Sampling comments: "Eight expeditions were carried out on each remnant from October 2011 to September 2012, always covering different portions. We installed ten mist nets (12 × 3 m, five shelves, 19 mm mesh) to capture birds in the forest understory from 05:00 to 11:00 for two consecutive days on each visit... The mist nets were installed as line clusters of five in the first 60 m from the forest edge and after 180 m, in the forest interior. The total mist-net effort was 2, 880h"
