- Habitat loss
- Predation by sugar glider possums
The Swift Parrot is a Tasmanian-breeding parrot species that feeds almost exclusively on nectars and pollens from flowering eucalyptus trees. It is a nomadic foraging bird that travels far and wide in search of suitable food.
It is described as being smaller than a Rosella Parrot but bigger than a Budgerigar Parrot – about up to 25 cm in length during adulthood. The Swift Parrot breeds during the months of February and March and then flies to Australia as a group (usually up to 500 birds in a flock) in the winter season to stay in forest sites where there is plenty of nectar supply.
The fast dwindling of the Swift Parrot population is mainly attributed to the overharvesting of the forest and woodland trees where it does not just inhabits but also where it gets its food sources such as nectar, pollen, and other parts of flowers. Wood chipping activities of the Eucalyptus Globulus Tree (or Tasmanian Blue Gum) limits their nesting options and seriously affects their breeding cycle.
When the Swift Parrot cannot find a proper tree hollow nesting ground where it can hide safely from predators, it can easily be killed and eaten by sugar glider possums. And with the proposed construction of a dam to support a golf course and fish farm within the surrounding areas, population growth will certainly be a challenge to pursue.
