Popis:	Isolation calls of captive squirrel monkeys were recorded by separating infants from their natal group members and then permitting vocal contact between the "lost" baby and the group at systematically varied distances. Separated infants gave longer calls at greater separation distances from their natal group members, and responding adults and juveniles similarly extended the length of their vocalizations. In the longer variants, a highfrequency element was prolonged, which is considered to be an example of the net advantage of a "frequency window" in the ambient noise of environments.
