Avifauna of São Camilo State Park: the importance of this semideciduous seasonal forest fragment for bird conservation

Abstract

The São Camilo State Park is a protected area of an important remnant of Semideciduous Seasonal Forest in western Paraná, a region highly threatened by deforestation. Although conservation areas such as the São Camilo State Park are important for preserving biodiversity, knowledge about the local avifauna is limited, with the only available study conducted 17 years ago. Thus, this study presents an inventory of the avifauna of the São Camilo State Park through point counts, mist nets, naturalistic observations, and citizen science data. We recorded 222 birds species (25 Orders and 56 Families), representing approximately 29% of the bird fauna of Paraná state. Five regionally threatened species were found in the area. Twelve species are endemic to the Atlantic Forest, nine are classified as migratory, and 26 are partially migratory, 21 taxa are forest-dependent, while 83 are semi-dependent. There is a predominance of insectivorous, omnivorous, and frugivorous birds. A total of 179 species were added to the original species list of the area. Our results highlight the importance of the São Camilo State Park for the conservation of birds in the Semideciduous Seasonal Forest in western Paraná.
