摘要

We all know, if only vaguely, that birds are great navigators. A good example is the swallow, which might spend the northern summer nesting under English eaves before migrating to South Africa for the winter-only to return the next summer to the very same nest site. It does not take much reflection to realize that these birds must have sophisticated navigational capabilities. But a deeper look into bird migration shows that many other species are capable of equally astonishing acts of navigation. To perform them, they rely on a wide scope of techniques, incorporating optics, acoustics, magnetism and celestial mechanics.
