Abstract:

In the North American Evening Grosbeak Hesperiphona vespertina, body weight about 60 g the respiration was recorded during distress calls. The calls were produced in the expired airstream in pulsations of 55-60sec. The inspirations lying between the calls had increased tidal volume and airflow velocity relative to rest. The duration of inspiration was only 0,1-0,15 sec, which is very similar to that in flight. Author
