Abstract

Anodorhynchus hyacinthinus is a cavity-nester that competes with other bird species for cavities. Here, we describe the dispute fora cavity between a pair of Anodorhynchus hyacinthinus and an individual of Tyto alba, which ended with fatal consequences to the latter. We also discuss briefly factors involved in this interaction.
