The species of an orange-bellied parrots in Australia are endangered with the spread of a virus.
The common stomach virus is posing a threat to the orange-bellied parrots at a breeding program for them. With the effect of the virus, the feather of birds start falling and their immune system weakens.
The breeding program being conducted at Healesville Sanctuary, Adelaide Zoo and Taroona involves 160-170 of the birds, as revealed by the Zoos Victoria Web site.
The occurrence of the disease in the captive breeding program could prove lethal to the birds, as only 50 birds of the same species have left in the wild, as told by Shane Radial, a professor of Veterinary Science at Charles Sturt University to the Australian Broadcasting Corp.
He said, "In captivity infections just find it easier to spread from one bird to another and there is no cure for the virus".
