The survey of rookeries and winter rook roosts in the area of the CNHSS Regional Survey was undertaken in 1945 by Dr [later Professor] RG Newton, as a contribution to the Rook Investigation, a project carried out under the direction of James Fisher (d 1970) for the Agricultural Research Council. The results were published as RG Newton, 'Rook Survey Work' by the Ornithological Section, Proceedings of the CNHSS, vol 11 (1948), pp309-314. An introductory paper by RG Newton and James Fisher, 'The Reasons for the Survey of Winter Roosts used by Rooks', explaining some of the methodology used, is published in the same place, pp303-308.
Donated by Professor Roy Newton, September 1996.

Scope and content
Survey sheet, and two plans, of rookeries in the CNHSS Regional Survey area. They are based on the original survey work of 1945, but include more detailed data than appears in the published papers. They were originally inserted into a copy of the loose-leaf Regional Survey Atlas of Croydon and District (CNHSS, 1936 onwards), and the plans are therefore numbered as sheets 170 and 171.
