THE population of Carnaby’s black cockatoos is declining by 10 percent each year, warns BirdLife WA’s Adam Peck.
Data from the annual great cocky count suggests there’s only around 1600 Carnaby’s left in the coastal plains between Mandurah and Gingin and their population continues to decline as their habitat is cleared to make way for housing, forestry or agriculture.
The ninth annual great cocky count will be held in April and bird enthusiasts across south-west WA are encouraged to take part as the census — WA’s biggest survey of black cockatoos — is used by the government when making important planning and conservation decisions.
“This is the most reliable cockatoo count of this variety,” says Mr Peck, BL project coordinator.
“Last year there were 700 registered volunteers.
“It gives very important data on black cockatoo numbers and movements.
Volunteers registering before March 19 will be assigned a roost site which they’ll watch for one hour during sunset on April 9 as the birds come home to roost.
