There have been three transactions into the wild of Perth Zoo breed for release species. On 26 June this year, 22 dibblers were released into Peniup Nature Reserve, in Western Australia’s south west. Thirty Western swamp tortoises were released at Twin Swamp Nature Reserve on 10 July and a further 38 into the Moore River Nature Reserve on 26 July.
On 6 July, four male and three female Critically Endangered Western Ground Parrots, endemic to the south west of WA, were transferred from the Department of Parks and Wildlife aviaries near Albany in the state’s south west to Perth Zoo. The birds have settled into their newly renovated aviaries well, and the breeding season will begin shortly. Staff are aiming to develop and document captive breeding and rearing techniques for this unique species. If successful, the potential to expand the program into a full-scale conservation breeding program will be explored.
Also transacted into the Zoo were four wonga and six brush bronzewing pigeons on 15 July from Healesville. Two male and four female feathertail gliders arrived from Taronga Zoo on 20 August and six female pygmy marmosets were transacted to Hunter Valley Zoo on 7 August.
One adult male Western Swamp tortoise was transferred to Adelaide Zoo on 14 August to improve the genetics of their captive breeding program, and five swamp tortoises (one adult female and four two year-old juveniles) were transferred from Adelaide Zoo to Perth Zoo on 20 August to free up breeding space and to allow the four juveniles to be released into the wild in the next few years. The transfers were endorsed by the Western Swamp Tortoise Recovery Team and approved by the Department of Parks and Wildlife.
