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.

Climate change 'has affected a third of UK bird species'

2 September 2019
Cuckoo numbers are in steep decline across almost half of England because of climate change but buzzards are up, according to a new study.
The British Trust for Ornithology (BTO) has looked at which species are most hit and helped by climate change.
Researchers found weather changes had a long-term effect on about a third of the 68 species studied.
BTO science director James Pearce-Higgins said there were "winners and losers".
Thirteen species have seen a greater than 10% rise in population numbers while three have suffered big drops.
Which birds are suffering and why?
Migratory birds are the biggest losers.
In five of the 11 regions studied, cuckoos, which have seen a population drop of more than 80% in the past 30 years, were the bird with the biggest fall in numbers.
The swift and turtle dove, which are also migratory, had the biggest drops in two areas each.
Cuckoos, which are on the RSPB's red list for conservation, are in the UK between April and June for breeding season.
The birds' journey back to Africa takes them via Italy or Spain, the latter having been hit by droughts brought on by warmer weather, the BTO said.
