| ABSTRACT This study reports a successful reproductive event in Megascops choliba in eastern Acre, northern Brazil. An active M. choliba nest was monitored from the hatching of the eggs to the departure of the nestlings. Once hatched, the nestlings were weighed every two days to verify their weight gain over time. The nestlings remained in the nest for 30 days. The pattern of weight gain was similar to that found in other birds, presenting a rapid increase over the first 15 days, followed by a drastic reduction in the mean growth rate during the second half of the development period. Our observations indicate that the breeding season of M. choliba in southwestern Amazonia is similar as that reported for the species in the northern hemisphere. These are the... |

| Se estudió la dieta de la Lechucita Vizcachera (Athene cunicularia) en dos áreas con diferente uso de la tierra en el sector central de la ecorregión del Monte de Llanuras y Mesetas, en la provincia de La Pampa, Argentina: en un área protegida (el Parque Nacional Lihué Calel) y en un establecimiento ganadero sujeto a pastoreo intensivo (estancia La Manuela). Se identificaron 1251 ítems presa, en su mayoría correspondientes a Coleoptera, Scorpiones y Rodentia. La Lechucita Vizcachera presentó hábitos tróficos generalistas. La importancia numérica de los distintos ítems presa en la dieta varió significativamente entre ambas áreas, tanto durante la estación reproductiva como durante la no reproductiva. Sin embargo, el peso promedio de los pequeños mamíferos... |
