dc.description.abstractThe food habits of the barn owl (T. alba) in the Mediterranean-climate areas of central chile and southern Spain were examined. In both areas most prey were small mammals (95% and 87% in Chile and Spain, respectively). Spanish barn owls frequently fed on reptiles and amphibians (4.5% of the diet), whereas such prey were not consumed by Chilean barn owls. The most noticeable difference involved mean body weight of small mammal prey (70.7 g in Chile vs. 21.2 g in Spain), which was associated with the different weight ranges of small mammals present in the 2 areas (40-320 g in Chile vs. 2.5-390 g in Spain). The narrower diet and specialization on mammals by Chilean barn owls was probably accounted for by the greater availability of larger small mammals and also perhaps by their greater overall density. In spite of the different prey weights taken by the owls, their body weights were similar in the 2 areas. These results are discussed in relation to the species configuration of the owl communities in Chile and Spain.
