The diets of single Powerful Owls roosting in two inner city parks in Melbourne, Victoria, in 2008 and 2009 were analysed. Common Brushtail Possum Trichosurus vulpecula and Common Ringtail Possum Pseudocheirus peregrinus were the only prey species recorded in the Fitzroy Gardens (occurring in equal numbers in the Owl’s diet), whereas Common Brushtail Possums and Black Rats Rattus rattus were recorded in the diet of the Flagstaff Gardens bird. This is a less diverse prey selection than recorded in the only other inner city dietary analysis for this species.
