Glossy Black Cockatoo Recovery Program
The South Australian subspecies of Glossy Black Cockatoo (Calyptorhynchus lathami halmaturinus) is listed as an Endangered Species at the national and state level. It has disappeared entirely from the mainland, and is now restricted to Kangaroo Island. In 1995, the population was estimated to be less than 200 individuals and declining. In response, a recovery program was implemented, which aims to ensure that a viable breeding population of the Glossy Black Cockatoo persists in South Australia. Since then, the downward trend has been reversed by hard-working staff and volunteers, and numbers are on the increase. Last year 330 Glossies were counted in the annual census - the highest number yet.
The SA Glossy Black Cockatoo requires high quality Drooping Sheoak (Allocasuarina verticillata) woodland for foraging, and large hollow-bearing eucalypts for roosting and nesting. The chief cause of the Glossy Black Cockatoo's decline in the 1900s was the large scale clearing of large old gum trees and sheoaks for agriculture. In addition to the loss of habitat, research indicated that predation of eggs and young chicks by the Commom Brushtail Possum was a major cause of nest failure.
The Recovery program needs your help to address these threats by carrying out important actions such as re-establishing and protecting critical habitat on Kangaroo Island, and putting "collars" of corrugated iron around nest trees to exclude possums.
