Since the publication in 1951 of a paper read to the Institute on bird navigation, a number of significant advances have been made in this field and a brief review of such progress will not be out of place. Most of this recent work has been concerned with the ability of birds to home to an area previously known to them. A useful summary, in English, has been published on the experiments done in Germany on the simple, inherited, one-direction movements of young birds on their first migration. The use of the Sun as a compass, in at least many cases, appears to be well established.
