Abstract : A laboratory study of the basis of visual acuity in man suggests that vision may not be a limiting factor in astronavigation among vertebrates. Field observations of pigeons navigating without the aid of celestial clues show that the birds shake their heads sideways at intervals. This confirms a prediction made by Ising on the assumption that birds use their semicircular canals for estimating latitude and directions from Coriolis force differences. (Author)
