In this study the community of birds in a small size remnant (10 ha) of Araucária forest, located in the city of Tijucas do Sul, Paraná was evaluated. During the period of November, 1999 to April 2001, 15 surveys had been carried, in which capture with mist nets and visual and aural contacts were used to estimate avian abundance and richness. We recorded 118 species of 35 families. According to the frequency of occurrence around 44% of species were considered with low frequency. When analyzed the trophics guilds, omnivorous and insectivorous of foliage were the most representative. By the capture method had been gotten 501 captures of 47 species. The capture species had relative abundances varying from 0.31 to 13.16% and the uniformity index was 0.83, demonstrating that the avian assemblage had a low dominance of some species. The structure of avian assemblage registered is expected for a small size remnant, with high relative abundance of generalists species and guilds, and the presence of a high number of species with low frequency of occurrence. Despite of, the specific composition presents a great number of species forest dependents showing that this forest remnant has a important role in the maintenance of species regionally.
