This paper provides the avifauna composition recorded between January and December 2003 in the Fonte Grande State Park (PEFG), municipality of Vitória, state of Espírito Santo, Brazil. We obtained a total of 120 species belonging to 37 families, after 450 hours of field work. We estimated a richness of 146 species (129 < IC(95%) < 163), according to Jackknife 1 method. However, the species accumulation curve has not reached its assintotics. Four species out of 120 recorded are endemic to the Brazilian Atlantic Forest (Leucopternis lacernulatus, Phaethornis idaliae, Thamnophilus ambiguus and Attila rufus), and one of them (L. lacernulatus) is included in the list of Brazilian birds threatened with extinction. The comparison among the three basic inventory methods (auditive, sightseeing and net capture) revealed that the sightseeing method detected the largest number of species (x² = 17.55, p < 5%), of which 26 (22%) were recorded exclusively by this method. This result is explained by the dominance of open landscape species in the Park, associated with the type of field work employed in this study.
