The birds are found in the south-west of Western Australia, and the fund says numbers have fallen by more than 50 per cent in the past 45 years.
It blames the rising development in the area which is destroying the birds' habitat.

Michael Roache from WWF says plants in the birds' habitat need to be replanted.
"We don't necessarily place the true value on environmental services or indeed habitat for biodiversity. In south-west WA we have so many threatened species because of those threats of development," he said.
