Satin bowerbird (Ptilonorhynchus violaceus ) sounds

Okay this is a treat -first of all forget the video - I couldn't get a clear shot of the birds, but there's two Satin bowerbirds (Ptilonorhynchus violaceus ) in this tree - a male and a female - and one or both of them were making the most amazing sounds. The audio is just from the camcorder and I've fiddled with it a bit to try and focus on the bird sounds, but it's not entirely clean. I normalised it, hard limited it and eq'd it a bit. It's just a great display, and would make R2D2 proud. I'm going to keep an eye out for these birds - they're in a park I go through regularly - with any luck there'll be a bower on the way.
