You often hear Corellas long before you see them - and usually at times of the day when their noisy squawking is less than welcome, but what exactly are these loud, restless birds up to?
Corellas are natives - they're members of the Cockatoo family and their distribution in Victoria is fairly restricted although as retired DSE employee Phillip Du Guesclin points out, they do seem to be expanding their range.
