Barn Owl Tyto alba pellets and loose bones on a cave floor from Amorgos Cyclades, Greece were examined and the birds found to have caught at least 39 species of bird, mostly identified from humeri, plus shrews Crocidura suaveolensa few lizards and dung beetles, in addition to their principal diet of rodents rats Rattus rattusmice Apodemus spp. Amongst the birds, migrants appeared most vulnerable to owl predation, with some notable exceptions, while resident species were under-represented.

The range of bird species found appears to be the largest recorded for is owl predators or prey Barn Owl study of a single site. Considerable differences were found in species proportions of taxa in fresh pellets and in loose bones, probably due to differential rates of degradation.
