Abstract
The South Australian Glossy Black-Cockatoo Calyptorhynchus lathami halmaturinus is extinct on mainland Australia, and occurs only on Kangaroo Island. Between 1995 and 2016, a successful long-term Recovery Program more than doubled the population of this taxon on Kangaroo Island. This paper documents the first records of nesting by Glossy Black-Cockatoos on the Dudley Peninsula on eastern Kangaroo Island in 2015 and 2018, at a time when flock size had increased to 35 individuals in post-breeding counts on the Dudley Peninsula. Nesting there is evidence of the growth and expansion of the Glossy Black-Cockatoo population over the past 25 years, which is likely a result of conservation efforts. This new eastern nesting site expands the breeding range of this subspecies ~13 km east, and to the part of Kangaroo Island that is closest to mainland South Australia.
