First evidence of collared forest-falcon (Micrastur semitorquatus: Falconiformes: Falconidae) nesting in Argentina and a new case of macaw’s nest usurpation
The collared forest-falcon (Micrastur semitorquatus) is distributed from Mexico to the south, the subspecies M. s. semitorquatus reaching Argentina, found in wooded and forested environments. Although it is mentioned that it breeds in the country, to date, no nests of the species have been recorded. Here we report the finding of a nest with two fledglings in forests of the Salta province. The nest was found on a rocky wall at 45 m height, in a hollow that had been occupied by a green macaw (Ara militaris) in the previous reproductive season. We describe the nest, fledglings, vocalizations, and the interaction with the macaws. Because the collared forest-falcon has high site fidelity and is common in the study area, it is probable that events of negative interaction, nest occupation and usurpation with the green macaw will occur in future reproductive seasons.

El halcón montés grande (Micrastur semitorquatus) se distribuye desde Méjico hacia el sur, llegando a Argentina la subespecie M. s. semitorquatus, que habita ambientes boscosos y selváticos. Si bien se la menciona como nidificante en el país, hasta la fecha no se han registrado los nidos de la especie. En este trabajo, se reporta el hallazgo de un nido con dos pichones en bosques pedemontanos de la provincia de Salta. El nido se encontró en una pared rocosa de 45 m de altura, en un hueco que había sido ocupado por una pareja de guacamayo verde (Ara militaris) en la temporada reproductiva anterior. Se describe el nido, pichones, vocalizaciones, y la interacción con los guacamayos. Debido a que el halcón montés grande tiene alta fidelidad territorial y a que es una especie común en el área de estudio, es probable que se produzcan eventos de interacción negativa, ocupación y usurpación de nidos con el guacamayo verde en futuras temporadas reproductivas.
