Abstract

ZUNIGA, Alfredo H.; FUENZALIDA, Víctor  and  SANDOVAL, Rodolfo. Food habits of barn owl Tyto alba in an agroecosystem in southern central Chile. Ecología en Bolivia [online]. 2018, vol.53, n.1, pp. 7-15. ISSN 2075-5023.

The Barn owl (Tyto alba) diet is described in an agroecosystem located at 20 km South of Mulchén, in south-central Chile. This was studied through the systematic collection of pellets and further analysis in laboratory. It was emphasized the predominant presence of mammals (rodents; 81.9%), followed by birds (passerines; 9.6%), and to a lesser extent, by invertebrates (3.6%). Ecological elements involved in this pattern are discussed.

Keywords : Abrothrix; Chile; diet; lagomorphs; rodents.
