 Another threat to the swift parrot is predation by sugar gliders on the mainland, hence why it is so important for the birds to seek refuge on offshore islands where they can breed safely.Some, but not all of the breeding and nesting sites are encompassed by the South Bruny Island National Park, with some land being privately owned and other land forestry owned- which operations are still active on Bruny Island.Approximately 80% of swift parrot habitat occurs outside of protected areas, which is detrimental in the protection of the bird due to its migratory nature, with habitat connectivity being key.
