SUTHERS, Roderick A.. Vocal mechanisms in birds and bats: a comparative view. An. Acad. Bras. Ciênc. [online]. 2004, vol.76, n.2, pp.247-252. ISSN 0001-3765.

Vocal signals play a very important role in the life of both birds and echolocating bats, but these two unrelated groups of flying vertebrates have very different vocal systems. They nevertheless must solve many of the same problems in producing sound. This brief review examines avian and microchiropteran motor mechanisms for: 1) coordinating the timing of phonation with the vocal motor pattern that controls its acoustic properties, and 2) achieving respiratory strategies that provide adequate ventilation for pulmonary gas exchange, while also facilitating longer duration songs or trains of sonar pulses.

Keywords : birdsong; echolocation; minibreaths; respiration; vocalization.
