对10种鸟类的研究表明，鸟类飞行时的呼吸与翅拍通常是协调的，但这种协调不是强制性的。呼吸与翅拍同步（1∶1协调）仅见于鸽和乌鸦，其余物种均表现出其它11种协调类型中的一种。鹌鹑、鸭、野鸡等翅拍频率较高的鸟类（翅小的鸟类），其翅拍频率的比例为5∶1。在物种内部，甚至在飞行过程中，协调的类型发生了变化，同时呼吸频率也发生了突然的变化。在大多数情况下，吸气的开始与上行（结束）有关，呼气的开始与下行结束有关。
SummaryInvestigations in 10 species showed that respiration of birds in flight is usually co-ordinated with wing beats, but the co-ordination is not obligatory. Respiration synchronous with wing beats (1∶1 co-ordination) was found only in pigeons and crows, the other species exhibited one of 11 other types of co-ordination. Quails, ducks and pheasants, birds with relatively high wing beat frequencies (with relatively small wings) showed a 5∶1 co-ordination. Within species, and even during a flight the type of co-ordination changed, and simultaneously there were sudden changes in the respiration frequency. For the most part, the beginning of inspiration was linked with the (end of) upstroke and the beginning of expiration with the end of downstroke.
