Avian ecology and behavior

In Brazil, the number of animals killed by vehicle collision surpasses 475 millions/year, but the actual number may be even higher since roadkill data in the country is scarce and punctual. Using a standard protocol, the project Caminhos da Fauna monitored since 2006 the avifauna roadkill in the BR-040 (RJ/MG) highway, southeastern Brazil. Here, we present a checklist of the avifauna registered during the 10-year monitoring program, including the list of roadkills, indicating threatening status at regional, national, and global levels, and the number of records/species. We registered 1,317 individuals belonging to 180 species, 21 orders, and 48 families. Another 247 individuals could not be identified. For seven families roadkills were higher than 50 individuals: Thraupidae, Cuculidae, Strigidae, Tyrannidae, Psittacidae, Columbidae, and Turdidae. The most collected species were Crotophaga ani (n = 106; Cuculidae), followed by Psittacara leucophthalmus (n = 61; Psittacidae), Piaya cayana (n = 56; Cuculidae), and Asio clamator (n = 44; Strigidae). Five species were under threat: Penelope obscura, Primolius maracana, Pteroglossus bailloni, Ramphastos vitellinus, and Sicalis flaveola. Most species were geographically widespread, while other 13 (7.2%) were endemic. Given the considerable amount of data obtained, further efforts of the same motivation in other Brazilian roads and express transportation systems should be encouraged.
