| The diet of Red-backed Hawk (Buteo polyosoma) was quantified by analyzing 40 pellets collected during winter and spring 1999 and winter 2000 in a forested area of Aysén, Chilean Patagonia. Rodents were the most numerous prey (82% of all prey), and accounted for the highest contribution to total biomass (83%). Among rodents, Oligoryzomys longicaudatus was the most consumed prey species, accounting for 70% of total number and 64% of total biomass. Birds accounted for less than 6% in number, but their biomass contribution was significantly higher (more than 15%). Insects constituted 12% in number, but less than 0.5% of total biomass. The Red-backed Hawk seemed to consume Oligoryzomys longicaudatus according to their field abundance. Also, it seemed to prey... |

| ABSTRACT People’s perception on birds of prey is heavily influenced by its intrinsic value, utility, myths and superstitions. In particular, negative perceptions may encourage poaching and persecution of these birds, affecting their conservation status. One nocturnal raptor species widely distributed across the world is the Barn Owl (Tyto alba, Tytonidae). In Chile, this species has been recorded and studied exclusively in rural and sub-urban areas. However, in the city of Valdivia Barn owls exist within the city boundaries. In this study we documented the feeding habits of Barn owls nesting in urban settings of Valdivia, and we analyze the opinions of local neighbors toward the owls. To characterize the diet of owls, we collected all pellets... |

| At present, 20 species of Oligoryzomys (Rodentia, Sigmodontinae) are recognized in the Neotropical region, most of them distinguished by their karyotypes, which fluctuates between 46-70 chromosomes. Two species are currently recognized in Chile, Oligoryzomys longicaudatus (Bennet, 1832; "colilargo" or the long-tailed pygmy rice rat; 2n = 56), which ranges from 27° to approximately 51° S, and O. magellanicus (Bennet, 1836; Magellanic pygmy rice rat; 2n = 54), south of 51° S in the Patagonian region of Chile and Argentina. As part of an ongoing research on the southern Patagonia of Chile, we report the results of small mammal samplings in six localities. We karyotyped 28 specimens and we also sequenced the hypervariable mtDNA region I in 22 individuals,... |
