The Crowned Eagle (Harpyhaliaetus coronatus) has been considered an endangered species by IUCN since 2004. The world population was estimated at less than 1000 individuals and their populations are declining. This is a large eagle that inhabits open woodlands in xerophytic forests of different biomes along its distribution that ranges from southern Brazil to northern Patagonia in Argentina.

Human persecution is the most significant threat to the endangered Crowned Eagle in central Argentina. This is because of an incorrect local belief that the eagles prey on livestock.

We are using satellite transmitters to investigate the habitat use and movement patterns of young Crowned Eagles. This information is critical in understanding the interactions between local ranchers and eagles and changing human perceptions on eagles and livestock.
