Diet Composition of the Austral Pygmy Owl in a Peri-Urban Protected Area in South-Central Chile
The diet of the Austral Pygmy Owl, Glaucidium nana, a small raptor, was studied by pellet analysis. During fall of 2020, 52 pellets were collected in a peri-urban protected area. Amongst 122 prey items, Muridae, represented exclusively by the alien species Rattus rattus and Rattus norvegicus, made u...
