This chapter explains how orientation refers to an animal's ability to move or posture itself in a desired direction relative to its environment. The ability to orient is virtually a universal feature of animal life. Many animals go a step further and navigate through the environment, finding their way from their current location to a specific destination that might be meters or kilometers away. Orientation mechanisms, and even more those that underlie navigation, are often complex and multimodal, involving not only visual cues but also sensory information about gravity, magnetic fields, chemical stimuli, mechanical and auditory cues, and even internal stimuli. As for so many other aspects of visual ecology, many of the critical observations have involved invertebrate animals, but work on vertebrates is very active as well.

Keywords:   visual orientation, animals, navigation, orientation mechanisms, visual cues, gravity, magnetic fields, chemical stimuli, auditory cues, internal stimuli
