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.

Bird population declines in Alberta’s boreal forest
EDMONTON - More than 20 per cent of Alberta’s boreal forest has been directly altered by human activities, leading to a corresponding decrease in terrestrial bird populations, a report released Wednesday reveals.
The study, conducted by the University of Alberta’s Biodiversity Monitoring Institute, explores the relationship between development and the abundance of common bird species in the boreal forest, an ecological zone that represents 58 per cent of the province’s land area and covers a vast expanse of the north, including Grande Prairie, Fort McMurray and the oilsands region.
The report shows that as of 2010, 21 per cent of the boreal forest had been affected by a variety of activities, including agriculture, forestry and energy production, resulting in bird populations 80 per cent of what would be expected if there was no development.
