Resumen:
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 werecollected. We identified 2774 individual prey items. Insects were the most consumed prey (63.56%), followed by rep‐tiles (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.
