Wildlife managers are learning more about the numbers and distribution of the endangered Carnaby's black cockatoo following the results of a survey of nocturnal roost sites across Perth.
Carnaby's cockatoo has halted a massive residential development in Mandurah. Image by ragimuffin A legion of volunteers is preparing to count specimens of the threatened Carnaby's black cockatoo across Perth on Wednesday, April 7.
The survey, organised by Birds Australia and the Department of Environment and Conservation, aims to determine the cockatoo's population from Moore River in the north, east to York and south to Yalgorup.
The count will help determine whether the population has declined or increased since the last tally was taken in 2006.
More than 1000 volunteers participated in that survey, which found there were at least 4500 cockatoos on the Swan Coastal Plain at the time.
