Communication and Perception
Toco toucans are very loud communicators with various means of sound production. Their repertoire consists of deep, course croaking that is repeated on a consistent basis. A rattling call is also a common form of conversation in this species. Besides vocal communication, they use bill-clacking as a form of auditory communication. Like all birds, toco toucans perceive their environment through visual, auditory, tactile, and chemical stimuli.
