My favorite David Attenborough moment has to be when he is in the Australian Forest (somewhere!!) and he watches the Lyrebird.
This bird is quite incredible, it mimics all the other birds in the forest, so well that it actually fools the lot of them. To top this off, it then mimics PERFECTLY a camera shutter, then a camera shutter with motordrive.....next we hear a car alarm.
But most astonishing of all, is the birds perfect mimicry of distant chainsaws in the forest, then the sound of the trees crashing down...absolutely astonishing.
