Abstract ∙ The Burrowing Parrot Cyanoliseus patagonus is known to breed in burrows mostly on cliffs and ravines in arid or semi‐arid regions of Argentina and Chile. However, during a tree cavity monitoring project we confirmed at least two active nests in tree cavities. Cavity entrances were located between 3.1 and 5.3 m above the ground in live caldén (Prosopis caldenia) trees, Parque Luro, province of La Pampa, Argentina. One nest failed while the other one successfully produced three fledglings. The absence of cliffs and scarcity of ravines in the region, and the presence of a nesting colony of the Blue‐crowned Parakeet (Thectocercus acuticaudatus) in the site may have promoted the adoption of this new nesting substrate for the species.
Resumen ∙ Nidificación inusual del Loro Barranquero (Cyanoliseus patagonus) en cavidades naturales de árboles El Loro Barranquero (Cyanoliseus patagonus) nidifica mayoritariamente en cavidades en barrancos y acantilados en regiones áridas y semiáridas de Argentina y Chile. Sin embargo, durante un proyecto de monitoreo de cavidades en árboles, confirmamos al menos dos nidos activos de Loro Barranquero. La entrada de las cavidades estuvo localizada entre 3.1 y 5.3 m de altura en árboles vivos de caldén (Prosopis caldenia), en Parque Luro, provincia de La Pampa, Argentina. Un nido fracasó mientras que el otro tuvo éxito produciendo tres volantones. La escasez de barrancos y la presencia de una colonia de nidificación de Calancate Común (Thectocercus acuticaudatus) en el sitio, podrían haber favorecido la adopción de este nuevo sustrato de nidificación para la especie.
