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.
