Little Lorikeet Glossopsitta pusilla nest hollow preparation and interspecific aggression in Melbourne, Victoria

Observations are presented of aggression between a pair of Little Lorikeets 'Glossopsitta pusilla' and an Eastern Rosella Platycercus eximius at a nest hollow, and nesting activity by the Lorikeets in inner eastern Melbourne, Victoria. Aggression between these two species does not appear to have been previously reported, while the timing of the nesting activity (autumn) is considered unseasonable for Little Lorikeets.
