Swift Parrot

Lathamus discolor

DecliningCRAUCRAU

Overview

A slender, fast-flying parrot around 25 centimetres in length, the Swift Parrot is characterised by bright green plumage, a red face and throat, and long, pointed wings and tail suited to rapid, direct flight. It is a specialist nectar and pollen feeder, favouring the blossoms of eucalypts, and in doing so acts as an important pollinator of Tasmanian and mainland forest ecosystems. It is one of relatively few migratory parrot species, breeding in Tasmania and crossing Bass Strait to spend the non-breeding season foraging across forests and woodlands of southeastern mainland Australia.

The species breeds in eucalypt forest in Tasmania, particularly areas where Tasmanian blue gum and black gum flower, and depends on tree hollows for nesting. Outside the breeding season it ranges through box-ironbark woodlands, coastal forests, and occasionally wetland-adjacent habitats in Victoria, New South Wales, and South Australia.

Its decline is driven by ongoing loss and fragmentation of breeding habitat through logging, agricultural clearing, and urban and industrial development. Predation by introduced sugar gliders on nesting females and chicks in fragmented Tasmanian forest has proven particularly severe. Competition for scarce nesting hollows, drought, shifting flowering patterns linked to climate change, and collisions with structures during migration compound these pressures.

Conservation efforts include habitat protection and restoration programs, nest box provision, monitoring of breeding populations, predator management trials, and research tracking migratory movements and habitat use. Some forestry practices have been adjusted to retain known breeding habitat.

Despite these measures, the population continues to decline, with estimates suggesting only a few thousand individuals remain. Continued habitat loss and predation pressure mean the species' long-term outlook remains poor without sustained, expanded intervention.

The Swift Parrot's biggest problems are the clearing and logging of the forests it needs for breeding and feeding, along with towns, farms, and industrial development taking over its habitat. It also faces deadly predation from introduced Sugar Gliders that raid its nest hollows, competition with other animals for those same nesting spots, and collisions with objects during its migratory flights. On top of this, droughts and shifting flowering patterns linked to climate change are making it harder for the birds to find reliable food sources. Overall, these threats appear to be ongoing and intensifying rather than easing, as habitat pressures and climate-related changes continue to compound existing risks.

Threat summary

Habitat

Swift Parrots breed exclusively in old-growth eucalyptus forests and woodlands of Tasmania, particularly those dominated by Blue Gum and Black Gum trees. During winter, they migrate to mainland southeastern Australia where they forage in eucalyptus woodlands, coastal forests, and urban areas with flowering trees.

Frequently asked questions

Why is Swift Parrot classified as Critically Endangered?
Swift Parrot is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. The Swift Parrot's biggest problems are the clearing and logging of the forests it needs for breeding and feeding, along with towns, farms, and industrial development taking over its habitat. It also faces deadly predation from introduced Sugar Gliders that raid its nest hollows, competition with other animals for those same nesting spots, and collisions with objects during its migratory flights. On top of this, droughts and shifting flowering patterns linked to climate change are making it harder for the birds to find reliable food sources. Overall, these threats appear to be ongoing and intensifying rather than easing, as habitat pressures and climate-related changes continue to compound existing risks.
