As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Land of the birds: why Australia has the world's greatest diversity of avian life


Australia is home to one in 10 of the world’s unique bird species – and most of the world’s birds can trace their lineage to the continent

If you live in Australia, you may not realise how unique and special the birds around you are. Our continent was perhaps the most important for the evolution of modern birds, with a majority of the world’s species tracing their ancestry here.

Long ecologically adrift as an island continent, Australia benefited through the evolution of a remarkable diversity of fascinating, colourful, noisy, clever, innovative species of bird.

Australia is home to about 830 species – more if you include neighbouring islands – nearly one in 10 of the world’s 10,000 or so living bird species. About 45% of these are endemics, found nowhere else.

We are lucky to have two of the world’s largest and heaviest birds – the flightless cassowary (which I’m backing in the Bird of the Year poll#teamcassowary!) and the emu – which are perhaps the most superficially similar to birds’ dinosaur ancestors. And related flightless ratites were probably already common across the ancient supercontinent of Gondwana long before Australia split from Antarctica and South America.
