Resumo

A quali-quantitative survey was carried out in two riparian forests fragmente (approximately 40 ha each) at Jacaré-Pepira river. Our intention was to characterize its bird community conceming richness, abundance and species occurrence in these areas. The qualitative survey showed 130 species at Santa Elisa (Brotas, São Paulo) and 151 at Morro Chato (Dourado, São Paulo), whereas the quantitative survey revealed the presence of 69 and 75 species at Santa Elisa and Morro Chato, respectively. The small size and the isolation might be responsible for the low number of species found. Observing the abundance index values (IPA) we realize that there are a few number of species with a high IPA on the one hand, while on the other there is a large number of species with intermediate and low IPA rates. A high detection coefficient (vocalization), low predatoiy rates and competition might have contributed for the higher abundance values found among these species. Furthermore, we have also registered species which are abundant in a fragment, but absent in the other, which might be explained by initial exclusion or local extinction. In spite of the riparian forests being protected by law, its clearing process has not stopped yet. Therefore, the study of this bird community is of uppermost impoitance for the elaboration of both conservation and management projects regarding these areas.

ABSTRACT

A quali-quantitative survey was carried out in two riparian forests fragmente (approximately 40 ha each) at Jacaré-Pepira river. Our intention was to characterize its bird community conceming richness, abundance and species occurrence in these areas. The qualitative survey showed 130 species at Santa Elisa (Brotas, São Paulo) and 151 at Morro Chato (Dourado, São Paulo), whereas the quantitative survey revealed the presence of 69 and 75 species at Santa Elisa and Morro Chato, respectively. The small size and the isolation might be responsible for the low number of species found. Observing the abundance index values (IPA) we realize that there are a few number of species with a high IPA on the one hand, while on the other there is a large number of species with intermediate and low IPA rates. A high detection coefficient (vocalization), low predatoiy rates and competition might have contributed for the higher abundance values found among these species. Furthermore, we have also registered species which are abundant in a fragment, but absent in the other, which might be explained by initial exclusion or local extinction. In spite of the riparian forests being protected by law, its clearing process has not stopped yet. Therefore, the study of this bird community is of uppermost impoitance for the elaboration of both conservation and management projects regarding these areas.

Key words: Bird community, unlimited distance point counts, riparian forest.
