The Pampas Meadowlark (Leistes defilippii) is an endemic songbird of the Pampa ecoregion, listed as Vulnerable globally. The population of this species has had a reduction of over 90% compared to its historical distribution as a result of the loss of grasslands transformed into agricultural fields. Today, most of its populations are concentrated in the southwest of the province of Buenos Aires in Argentina, and the surviving subpopulations are facing problems associated with small populations. Nest predation and unplanned grazing are among the main threats currently affecting these subpopulations.

The aim of our project is to develop management conservation tools that will increase the reproductive output of this threatened grassland species. Specifically, the objectives of this project are to increase the nesting success of Pampas Meadowlark by protecting active nests against predators and cattle, and to identify and protect key breeding sites of this grassland songbird in Southwestern Pampa.
