The Rookeries of the Isle of Wight

Abstract

THE nature and degree of the influence of the rook (Corvus frugilegus frugilegus L.) on agriculture have lately received considerable attention from ornithologists, and investigations have led to the taking of a census of rookeries in various parts of the country. The Isle of Wight appeared to be a particularly interesting area for the taking of such a census, as it is probably self-contained in the nesting season so far as the rook is concerned, and it presents a considerable variety of country. A census begun in 1931 was only completed in a part of the Island, but in 1932 the whole area was covered.
