Resumo: | Spatial distribution of birds was studied in 10 ha forest fragment at Londrina State University, southem Brazil (23º15'S, 51º10'W). Five habitats were categorized in the forest fragment: four related to the edges and one related to the forest interior. A line transect, crossing ali these habitats, was used to identify the bird species one day each two weeks from September 1996 to September 1997 totaling 57 days of samplings. The forest was divided into three leveis: understory (bellow 3 m), mid-levels (3-7 m) and canopy (above 7 m). Occurrence frequencies in each habitat and each forest levei were calculated for each of the 62 species identified during the field work. The number of species in each levei was similar (43 species in the understory, 42 at mid-levels and 40 in the canopy). Edges had higher number of species (51, 46, 33 and 30 species) and most of them with more than 50% of occurrence frequency. By contrast, forest had the lowest number of bird species (29 species), 80% of them with less than 50% of occurrence frequency, what suggest that the edge effect is strong on this forest fragment.
