The Sensory Ecology of Birds ranges widely across species, environments, and behaviors to present a synthesis that challenges previous assumptions about the information that controls the behavior of birds. A bird may use a wide range and combination of sensory information that comes from sight, hearing, smell, mechanoreception, taste, and magnetoreception. It may also include specific refinements of senses, such as echolocation and remote touch from the bill. The book recognizes that there are many complex and subtle trade-offs and complementarities of information between different types of sensory information.
