cockies

Well, we ought remember that Brushtailed Possums are known predators of nests.

So quite possibly the noise was justified.

Their introduction to New Zealand has had an horrific impact on bird species there.
Such behaviour in Australia is considered normal, but not extraordinary (but the Cockatoos are more likely to be able to protect/defend their nests than smaller birds).

I heard a lot of  noise about 10 pm one night last year. Three cockies were shrieking at a possum. It went on for some time.

Last evening, after dark, we heard cockatoos making a great racket for about 15 minutes and wondered what was going on.  This morning we found out that they had been wreaking havoc on one of our acacias, ripping off many quite large twigs.  They left 3 tiny white feathers as a souvenir!  Any ideas what might have been going on at that time of night?
