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.

Mohua numbers have risen more than 30-fold and overall, native bird numbers have doubled in the 21 years since monitoring began in 1998, recently analysed Department of Conservation (DOC) results show.
DOC Principal Science Advisor Dr Colin O’Donnell says the long-term study charts the response of 13 native bird species following sustained predator control to suppress rats, stoats and possums.
“Our most recent bird count data from last spring shows seven native bird species are still increasing in numbers, four species remain stable, and two have declined.”
“For the first time in 21 years, mohua have become the most common bird counted, which is what they would have been in this valley prior to European settlement.”
“The results are exciting because year by year we’re seeing a re-balance of the valley’s birdlife and don’t know when population limits will be reached,” says Dr O’Donnell.
