In the forests of Tasmania lives the swift parrot (Lathamus discolour), a highly threatened bird that breeds nowhere else in the world. New research published recently in Biological Conservation finds they are more at risk of extinction than previously thought, with introduced sugar gliders (Petaurus breviceps) and logging dealing two big blows to their remaining numbers.
The swift parrot is a small, colorful parrot with pointed wings and a long, pointed tail. Adult males are predominantly bright green and have a blue patch on the crown, a red frontal band, and throat and under-tail coverts. Adult females are slightly duller but with a prominent cream underwing-bar.
Globally, introduced predators are major drivers of extinction but native predators can also have serious effects, the authors write. In landscapes – particularly those modified by anthropogenic activities – multiple threats can be active simultaneously so synergistic interactions between different threats like predation and habitat loss accelerate the decline of prey populations. Island endemics are particularly vulnerable to predators and have suffered high rates of extinction following the introduction of predators.
