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.

Fossils may reveal 20-million-year history of penguins in Australia

Penguin history includes the 'giant penguin,' arrivals via multiple dispersals, extinctions

Multiple dispersals of penguins reached Australia after the continent split from Antarctica, including 'giant penguins' that may have lived there after they went extinct elsewhere, according to a study published April 26, 2016 in the open-access journal PLOS ONE by Travis Park from Monash University, Australia, and colleagues.

Penguin evolution in Australia following the continent's pre-historic split from Antarctica is not well-understood, but the fossil record shows that Australia was home to a number of penguin species. Only the little penguin remains today, and pre-Quarternary evidence of this species and its ancestors in Australia is lacking. To update our understanding of Australian penguin evolutionary history, the authors of the study analysed recently collected penguin fossils and compared them to known species, including now-extinct 'giant penguins,' and presented a new phylogenetic tree in the context of biogeographical events on the Australian continent.
