The Glossy Black-Cockatoo, Calyptorhynchus lathami, is the smallest of the five black-cockatoos. Populations have declined, with local extinctions and range contraction mainly caused by habitat clearing. More frequent and intense fires in south-eastern Australia since settlement have also reduced suitable habitat. Grazing, which suppresses casuarina regeneration, and forestry practices that remove casuarina also contribute to the species decline.
