Legal Requirements in South Australia A rescue permit must be obtained from the Department of Environment and Natural Resources to keep or care for any injured or rescued wildlife in South Australia. Mine are all long term captives on rescue permits or aviary bred so are okay in 25mm square wire aviaries. The aviaries are four meters long by 1.2 meters wide by 2.4 meters high. Each has a 1.2 meter corrugated iron shelter. There is a perch at each end of the aviary just like a parrot aviary.
Owls are birds of habit and sleep in the same spot on their perch each day.
This spot soon carries deep scars from their talons. Owls cough up pellets of bone and fur which they have been unable to digest. Scientists collect these pellets in the bush to discover what mammals, birds and reptiles live in the Owl's territory. I grow passionfruit vines over the aviary roofs to provide the dark aviaries Owls prefer as they are nocturnal creatures and sleep all day. Sometimes I have found eggshells on the floor of the Barking Owl's aviary and this puzzled me for awhile.
