The Magellanic Horned Owl (Bubo magellanicus) is one of the most common nocturnal raptors in Patagonia. The aim of this note was to analyze the food habits of this species in a small island from the Patagonian Atlantic coast. Four nesting areas and eight adults of Bubo magellanicus were found; 217 pellets plus disaggregated material were collected. We identified 2774 individual prey items. Insects were the most consumed prey (63.56%), followed by reptiles (13.73%), arachnids (10.92%), mammals (10.42%), and birds (1.37%). Our study show B. magellanicus feeding mainly on arthropods and introduced species, a fact that was not previously reported for this species in Patagonia.
