Summary Dietary samples from four Sooty Owl Tyto tenebricosa roost-sites within one territory in the Royal National Park, Sydney, New South Wales, were collected in December 2005. A total of 144 dietary items was identified, representing eight mammal species and at least one bird species. The samples were compared with those collected during a study 10 years earlier (in 1994-96) that included samples from the same roost-sites. Ten years later, the diet of the Sooty Owl in this territory appears little changed, except that the Sugar Glider Petaurus breviceps is now taken more frequently. The Common Ringtail Possum Pseudocheirus peregrinus continued to be the principal prey species taken by the Owls at this location. The Long-nosed Bandicoot Perameles nasuta may have declined in the Sooty Owl's diet during this period, but this trend was not significant statistically. This study showed that Sooty Owl diet at a single location is relatively stable, despite the occurrence of a major disturbance to habitat caused by a severe wildfire 12 years previously.
