This paper presents an analysis of 56 whole pellets and fragments of approximately 200 pellets of the Barn
Owl
Tyto alba, collected in August 1981 from the arid pastoral zone of north-eastern South Australia. The owl's
diet consisted of 67 per cent mammals (62% rodents}, 3 per cent birds, 30 per cent lizards and less than 1 per
cent insects by number, and 82 per cent mammals {74% rodents), 8 per cent birds, 10 per cent lizards and
less than 1 per cent insects by biomass. The introduced House Mouse
Mus domesicus was the predominant
mammal, and only rodent, recorded.
