Communication and Perception
There is a limited information on communication and behavior. This lack of knowledge is largely due to their nocturnal, arboreal, and solitary lifestyle. Their sense of olfaction is well developed, evident by the use of scent marking by males. Males scent mark on tree branches via glands surrounding the anus. The purpose of scent marking is to establish a meeting place with the females so that mating can occur. The female may also vocalize via a high-pitched scream to advertise to males she is ready to mate. These sloths are generally silent but have been known to hiss in times of high stress or when agitated. Separation of an infant from its mother will elicit a loud low-pitched distress call ranging from 30 to 90 seconds. Tactile communication has been observed in the form of grooming between infant and mother. This is a mutual behavior and involves licking the head, face, and anogenital region.
