HC Deb 27 November 1962 vol 668 c28W
71. Sir J. Duncan

asked the Parliamentary Secretary for Science what research is being, or has been, conducted into the principles used by migratory birds in maintaining the direction of their migrations; and whether this knowledge could be used to divert migratory woodpigeons from this country.

Mr. Denzil Freeth

Since the war a good deal of experimental work on the way in which birds navigate has been and is being carried out in this country, Germany and the U.S.A. The available evidence suggests that migrating birds make use of landmarks and the Sun's position by day and star patterns by night. Present knowledge does not offer any prospect of diverting migrating birds from this country.
