ABSTRACT: The present study focused on the Catimbau National Park in the municipality of Buíque, in the Brazilian state of Pernambuco, during the dry (October, 2008) and rainy seasons (April, 2011). The objective was to evaluate the species richness and the spatial-temporal variation of the park’s avifauna. Data were collected by mist-netting, line transect surveys, and the MacKinnon list method. A total of 179 species were recorded, of which 45 had not been reported previously for the park, raising the total number of bird species known to occur in this conservation unit to 202. A comparative analysis was used to verify differences between the São José plateau and the semi-arid lowlands, as well as the variation between the dry and rainy seasons.
