I have a large pergola out the back. When it rains, as it has been for about ten minutes, birds gather under the pergola to shelter from the rain.
There is a currawong under the pergola, chattering away. S/He's been there for a while, since the rain started. Puppy is mesmerised by the chatter.
You'll find a sound file for the Grey Butcherbird here. This is similar to what he sounds like, although he's a little quieter under the pergola. Just chattering.
Other birds at my place are:
Australian Raven (bloody Crow!)
Kookaburra (Laughing Kookaburra, pshaw, it's just Kookaburra)
Sulphur Crested Cockatoo
There are also the occasional Red Tailed Black Cockatoos, but they are not commonly found in many urban parts of Australia. They seem to arrive a few days before rain, anything from a few to a dozen. They make an awful racket, quite distinct from any other parrots we have here and even other cockatoos.
There are cockateils, rosellas, pale face rosellas, many more parrots!
