For centuries, humans have been fascinated by how migratory animals find their way over
thousands of kilometres. Here, I review the mechanisms used in animal orientation and …

Birds can use two kinds of information from the geomagnetic field for navigation: the
direction of the field lines as a compass and probably magnetic intensity as a component of …

Magnetoreception, the perception of the geomagnetic field, is a sensory modality well-
established across all major groups of vertebrates and some invertebrates, but its presence …

In migratory animals for whom post-natal care is limited, it is essential that there are inherited
mechanisms whereby an individual can navigate—first, to the terminus of their migration …

Migratory birds can sense the Earth's magnetic field and use it for orientation over thousands
of kilometres. A light-dependent radical-pair mechanism associated with the visual system is …

The exceptional navigational capabilities of migrating birds are based on the perception and
integration of a variety of natural orientation cues. The “Wulst” in the forebrain of night …

Animals use the geomagnetic field and astronomical cues to obtain compass information.
The magnetic compass is not a uniform mechanism, as several functional modes have been …

Billions of migratory birds navigate thousands of kilometres every year aided by a magnetic
compass sense, the biophysical mechanism of which is unclear. One leading hypothesis is …

Migratory birds use several different sources of orientation information. They have at least
three compass systems based on different cues: the sun and polarized light, the stars and …

The role of inherited orientation programmes in determining the outbound migratory routes
of birds is increasingly well understood, though less is known about the influence of …
