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.

Habitat variety crucial for Jays as temperatures warm


14/04/2019
Researchers at the University of Southampton have shown that an even range of habitats – chiefly forests, fields and meadows – are needed in an area of around 200 m2 to 1 km2 in order for Jays to thrive.
The data, published recently in Methods in Ecology and Evolution, showed that the higher the temperature, the more important it it is for Jays to have a mix of different surroundings in a relatively small space, with an even spread of coniferous and broad-leaved forests also necessary.
The study shows how habitat management will become increasingly important as temperatures rise. Data from the BTO's Bird Atlas 2007-11 was studied by the researchers, who focused on Jay as it's a species known to frequent a variety of ecosystems. The Atlas was one of the most ambitious volunteer projects undertaken, with volunteer surveyors allocated squares of land around Britain in which they counted every bird during winter and in the breeding season.
