Paperback. Condition: Good. THERE ARE NO TARIFFS OR CUSTOMS DUTIES ON BOOKS. G. V. T. Matthews wrote several influential works on bird navigation. This pamphlet developed the "sun-arc hypothesis," which proposed that birds could navigate by observing the sun's position and path in the sky. The pamphlet words, diagrams and maps are in good well used condition although there is some staining to a few pages and some wear to the front cover edges.
