The Swift Parrot (<em>Lathamus discolor</em>) is a small bird about 25 cm long. It is mostly bright green with some red, yellow and blue patches. The bright red patches under the wings are visible when in flight. It has a long thin red tail which distinguishes it from the rainbow lorikeet.
The Swift Parrot only breeds in Tasmania but spends the winter (March to October) in Victoria and NSW. On the mainland it is semi-nomadic, foraging on flowering eucalypts and lerps (a protective covering secreted by some insects).
The remaining stands of Swamp Mahogany are important food sources for the Swift Parrot in Warringah.
