Nest­ing boxes for birds

Cockburn Gazette - - BUSINESS -

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.
