title: Radiotelemetry of the Respiration of a Flying Duck.
abstract: Respirations of a flying wild mallard duck, Anas platyrhynchos, appear to be synchronized with wing beat in a ratio of 1 to 2. Wing beats come during exhalation and between respirations. The average number of respirations was 14 per minute for a resting duck and 96 per minute for a flying duck.
