میمونهای دراز دست - ستارگان آواز جنگلهای بارانی

Early in the morning, we sing spectacular songs awakening the stillness of the forest. Singing is very rare in mammals and, outside of humans, some say we produce the most complex songs of all land mammals. Song-bouts usually last about 10-30 minutes. Our songs reveal the singer’s sex and individual identity.
