Predation of woodland songbirds: grey squirrels have a case to answer

Two years’ research by the Game & Wildlife Conservation Trust indicates that grey squirrels have a significant effect on certain woodland birds’ fledging success. In a pioneering project, which tested the effects of removing grey squirrels from groups of woods, some birds experienced a better success in rearing fledged young than in a comparable group of woods where no squirrel control was undertaken.“The results from this research work indicated that grey squirrels at particular densities have a noticeable effect on some birds, particularly those which have open nests, rather than nesting
