Nesting boxes for birds
THREE nesting tubes have been installed at Manning Park to support the local Carnaby’s black cockatoos.
Mounted in tall trees at the popular reserve, the City of Cockburn says the tubes are designed especially for the endangered birds, mimicking an ideal nesting habitat.
There are estimated to be about 12,000 Carnaby’s in the Perth-Peel region, with their numbers declining by 10 per cent each year.
“The Carnaby’s black cockatoo is an endemic species that is under increasing threat from habitat destruction and development,” Cockburn Mayor Logan Howlett said.
“Large old trees with nesting hollows are being lost at an alarming rate.”
BirdLife Australia’s Carnaby’s black cockatoo project coordinator roosted at night. Phoenix Primary School is another.
But he said the new nesting tubes would have to be well managed.
“Carnaby’s don’t normally nest on the coastal plain, they migrate inland to the Wheatbelt for this,” he said.
“The benefit for Carnaby’s is therefore less clear although there have been a few reports of nesting on the plain so this may be a thing of the future.
“If the boxes end up being used by non-endemic species then this will adversely affect local species like Carnaby’s and ringnecks.
“On the whole BirdLife encourages the installation of nest boxes if they are well managed.”
The City has installed more than 50 other nesting boxes.
