Sounds and Vocal Behavior


Birds utter a low uuup when foraging, apparently a contact call. When disturbed they give a sharper whistle and ök-ök-ök while fleeing almost vertically up into trees to a perch 3-4 m above the ground (IBAMA 2004). This behavior makes the bird very vulnerable to hunters.

Males have a specific vocalization used throughout the year.

The adult male's breeding song is a deep low-frequency booming that carries long distances for attracting the female (IBAMA 2004).

Nonvocal Sounds
