Posible poliginia en el Aguilucho de cola rojiza (Buteo ventralis) en el sur de Chile
During the breeding seasons 2007−08 and 2008−09, I recorded a number of signs, which suggested to me the occurrence of polygyny in the Rufous-tailed Hawk (Buteo ventralis). Observations were made on the Adencul Hill in the Araucanía region, southern Chile.
