Bird surveys are essential for the identification of bioindicator species of environmental quality, endemic and threatened species, contributing for the conservation of several Brazilian ecosystems. The research was conducted in Trilha do Sol, municipality of Capitólio, Minas Gerais state, near the buffer zone of the Serra da Canastra National Park, a region responsible for one of the greatest bird richness in the country.

Five species are recognized as indicators of environmental quality: Lepidocolaptes angustirostris, Saltator similis, Sporophila plumbea, Porphyrospiza caerulescens and Antilophia galeata; the latest three being threatened, as well as Elaenia cristata, Saltatricula atricollis, Gnorimopsar chopi and Cypsnagra hirundinacea.
