Make no mistake about it, the Swift Parrot is in great danger of following in the footsteps of the Orange-bellied Parrot; they could also very easily become functionally extinct in the not too distant future. The widespread logging of Tasmania's old growth forests has decimated their breeding grounds, with the small pockets that are left now overrun with Sugar Gliders, an introduced predator of these small, predominantly green parrots. The Sugar Gliders were brought to Tasmania from the Mainland in the 1800s and are a huge threat to the remaining Swift Parrot population as they eat the their eggs, nestlings and the adults birds themselves in many cases.
The Swift Parrot also breeds on Bruny Island, which is shaping to be the species last safe haven. Read more on this here: https://science.anu.edu.au/news-events/news/anu-science-location-bruny-island
