Provide supplementary food for songbirds to increase adult survival
A controlled study in Wisconsin, USA, over five months in the winter of 1984-5 (Brittingham & Temple 1992) found that, following the removal of supplementary food, 49 black-capped chickadees Parus atricapillus did not have lower survival at a site where they had previously been provided with supplementary food, compared with 35 control chickadees, at a site where they had never been fed (84% monthly survival for previously-fed birds vs. 85% for controls). Food had been provided for 25 winters at the experimental site.
