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.

Colours of the Crimson Rosella parrot reveal a deadly secret

The vibrant colours of Australia’s crimson Rosella parrot might not in fact be quite as they seem. The colours covering its feathers could be the result of a virus that is known to kill other species. 

A research team from Deakin’s Centre for Integrative Ecology (CIE) and School of Medicine carried out an eight-year study of the Crimson Rosella and subspecies across New South Wales, Victoria, and South Australia. 

The Beak and Feather Disease Virus that the Crimson Rosella carry around so proudly in the colour of their feathers is surprisingly deadly in other parrot species. As such, the Australian Government have listed the Beak and Feather Disease Virus as a key threat to biodiversity under the Environment Protection and Biodiversity Conservation Act 1999. Justin Eastwood, Deakin CIE PhD student who worked on the project, explains: “The virus is only found in parrots; it’s no danger to humans, but the danger it presents to parrots seems to vary from species to species and it can be pretty nasty.”
