Avifauna on small farms aiming forest management in Fernandes Pinheiro city, Parana State, Brazil

Abstract

This work aimed to carry out a first diagnosis of local birds, concentrating in six fragments of Ombrophyllous Mixed Forest, using methods adequate to be repeated in subsequent periods. The assessment of birds on long-term may be used as local bio-indicator, especially because these areas will be managed in the future. In the sampledarea it was registered 124 species from 41 families. Four species listed in the Red Book of Threatened Fauna in the State of Paraná were recorded: Polioptila lactea (Creamy-bellied Gnatcatcher), Mesembrinibis cayennensis (Green Ibis), Accipiter superciliosus (Tiny Hawk) and Leptasthenura striolata (Striolated Tit-Spinetail). When the six forest fragments were assessed using the irregular transects method, it was registered 102 species. The trees survey, carried out by sample plots, resulting in 92 species. The Relative Frequency of wild bird community matrix and its sub-group of forest specialist birds presented significant correlation with the Coverage Value of the tree community (DBH ≥ 10cm).
