Annotated checklist of birds from Triângulo Mineiro and Alto Paranaíba in southeastern Brazil

The Brazilian region known as Triângulo Mineiro and Alto Paranaíba (TMAP) has some areas of high bird diversity. Yet, the region has not been systematically surveyed despite the large transformations its original vegetation has suffered over the past few decades. We report on the most comprehensive bird inventory of the TMAP region, in which we surveyed in 353 sites. For this, we used point transects (11,120 sampling hours) and mist nets (41,920 net-hours). We recorded 469 species belonging to 27 orders and 73 families. Forest-associated species represented 49.04% of the total, grassland and savanna species 38.81%, and aquatic species 11.73%. We found 44 endemic species and 37 species that are threatened at some level. An annotated list of the rare, endemic, and threatened species is provided. This study may serve as a baseline for future studies within the region, including those designed to identify areas of conservation priority.
