Control predatory mammals and birds (foxes, crows, stoats and weasels)

A before-and-after study on a mixed farm in central England (White et al. 2008) between 1992 and 2007 (a continuation of the data series used in (Stoate & Szczur 2001, Stoate 2002)), found that controlling predator populations (carrion crow Corvus corone, black-billed magpie Pica pica, red fox Vulpes vulpes and other mammals) appeared to increase blackbird Turdus merula breeding population. However, the authors caution that the study is not experimental and that other explanations for the trends seen cannot be eliminated.
