Admiral:
By David Attenborough, a Lyrebird imitating a chainsaw. It is famous for this ability and accuracy in mimicking other birds (and sounds in general), but it is still half unbelieavable to hear it performed, even on video.
Dînadan:
Makes you wonder if it should be called the Liarbird instead.
Abecedar:
We see them quite frequently as we drive through the mountains here to and from Canberra
