Carnaby's black cockatoo numbers 'increase dramatically' with artificial hollows
/Sarah Taillier for the ABC:
Artificial nesting hollows are helping revive the numbers of the critically endangered Carnaby's black cockatoo, after it lost part of its breeding heartland to bushfire in Western Australia.
The largest known nestling ground for the Australian bird species is in woodlands at a farm in Coomallo near Badgingarra, about 200 kilometres north of Perth.
