The Quebrada de los Cuervos (Spanish for Crows Ravine) is an important landform in Treinta y Tres Department, Uruguay.
Crossed by the Yerbal Chico creek, it constitutes a natural protected area.[1] [2] This Important Bird Area (IBA)[3] is inhabited by several endangered species, such as Agelaius flavus, Heteroxolmis dominicana, Limnoctites rectirostris, Sporophila cinnamomea, Sporophila ruficollis.[4] The very name of this place refers to crow-like Cathartidae which breed on its cliffs: Cathartes burrovianus, Cathartes aura, and Coragyps atratus.[5]
