Sugar gliders eat swift parrot eggs, chicks and even adult birds, drastically decreasing the reproductive success of the species. Swift Parrots are a critically endangered nomadic migratory bird found only in south-eastern Australia. This is a list of Psittaciformes species by global population.While numbers are estimates, they have been made by the experts in their fields. The female is slightly duller, with a creamy underwing bar. The Swift Parrot population was estimated at 1320 pairs by Brown (1989). The Swift Parrot, (Lathamus discolor), is a small 25cm bird with bright green plumage, the throat and foreparts of its cheeks are red; borders of the facial areas are yellow; the crown of its head is dark blue; vent and under tail coverts dull red; wing primaries violet-blue and its long central tail feathers are brownish-red (Forshaw, 1981). Swift Parrot Lathamus discolor. Brereton (1996) estimated 1,000 breeding pairs. Overall, the wild population of the migratory and nomadic Swift Parrot is in a nose-dive. Their impact on Swift Parrot populations in Tasmania has been devastating. Clearing of high quality breeding and foraging habitat has been a key driver of population declines over the past 150 years. Only recently it has been discovered that sugar gliders – introduced to Tasmania, are having a large impact on the Swift Parrot population, by killing nesting females, eating eggs and chicks. This list is not comprehensive, as not all Psittaciformes have had their numbers quantified. In fact, it’s estimated that nearly 85% of the Swift Parrot population is at risk each season of being killed by sugar gliders. Swift parrots prefer to nest in the tree tops of old growth forest.

Their small population of less than 2000 birds is continuing to decline largely due to loss of habitat in both their breeding range (eastern Tasmania) and non-breeding range in south-eastern mainland Australia. The most significant threat to this species is the loss of breeding habitat in Tasmania, primarily the harvesting of Tasmanian Blue Gum due to forestry practices including woodchipping. The body is mostly bright green, with a dark blue patch on the crown. The Swift Parrot is a slim, medium-sized parrot with a streamlined shape in flight, angular pointed wings and a long pointed purple-red tail. The forehead to throat is crimson and there is a crimson patch at the bend of the wing. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.. Species .
