Rediscovering and Protecting Chaco Eagle Populations in a Critical Area for its Conservation

18 Apr 2023

Expanding the Chaco Eagle Outreach, Research and Conservation Project towards New Areas in the Dry Chaco Ecoregion

During the first two Rufford Small Grants, our team gathered valuable information on the status of the Chaco eagle (Buteogallus coronatus) populations in the Dry Chaco in Argentina. With more than 200 sightings reported and more than 15 new nests found, we confirmed that this arid ecoregion is key for the conservation of this endangered species. However, a handful of episodes of mortality have occurred during these years, mainly by direct persecution, electrocution in power lines and drowning in water reservoirs. Thus, it is imperative to take a step forward, integrating all the knowledge acquired to promote conservation actions at a regional scale.

The aim of this project is to combine research and conservation efforts in order to promote the long-term survival of the Chaco eagle in the Dry Chaco of Argentina. First, we will explore new areas in this ecoregion, searching for breeding territories and nests with the aid of local communities, which will provide us with data on the presence and perception of this endangered species. This will help us promote agreements with institutions in order to legally protect this threatened bird. Second, we will monitor all identified Chaco eagle breeding nests across the reproductive season, to examine the diet, nest success and sources of mortality. Third, we will survey power lines across the area to identify risky pylons where the Chaco eagle (and other birds) could be electrocuted, and we will use this information to promote safer designs to regional energy administrations. Fourth, we will continue installing rescue ramps as a mitigation measure to reduce Chaco eagle (and other wildlife) drownings in water reservoirs. Last, talks at schools and meetings with producers will help us tackle potential conflicts that lead to direct persecution. This project will reinforce our long-term monitoring program in the Dry Chaco, contributing to the conservation of this endangered species.
