'Renowned for its unusual mammals, Australia is a land of birds that are just as unusual, just as striking, a result of the continent's tens of millions of years of isolation. Compared with birds elsewhere, ours are more likely to be intelligent, aggressive and loud, to live in complex societies, and are long-lived. They're also ecologically more powerful, exerting more influences on forests than other birds.

'But unlike the mammals, the birds did not keep to Australia; they spread around the globe. Australia provided the world with its songbirds and parrots, the most intelligent of all bird groups. It was thought in Darwin's time that species generated in the Southern Hemisphere could not succeed in the Northern, an idea that was proven wrong in respect of birds in the 1980s but not properly accepted by the world's scientists until 2004 – because, says Tim Low, most ornithologists live in the Northern Hemisphere.'
