This bird is so shy in its habits as to escape detection in plundering green peas, and accordingly has to be watched for incessantly to secure effective shooting. Netting out is the only safeguard, shooting being too expensive and uncertain for general adoption. As it is increased to excess in some localities, game-preservers should grant permission for the destruction of the nests in woods to persons not likely to disturb game, or give instructions for decimating this lover of apple and pear pips, and some say damsons and cobnuts and filberts. It is useful by capturing quantities of insects in summer, principally for its young, as many as forty caterpillars having been found in a female bird.
