Field surveys in montane Atlantic forest of Rio de Janeiro state, Brazil, provided a list of 82 bird species in four sites visited. Our protocol relied on standardized use of mist nets and observations. The birds recorded include 40 Atlantic forest endemics, three globally and two nationally Vulnerable species, and two regionally Endangered species. Data on species elevation are included and discussed. This work enhances baseline knowledge of these species to assist future studies in these poorly understood, but biologically important areas.
