HOUSING AND SOCIAL NEEDS (cont)
Housing designs should provide for the different needs of a species by allowing visual and auditory interchange with other animals. Breeding cages should provide security for raising offspring.
Outdoor runs and corrals should have perches or other climbing structures to provide monkeys with exercise and permit escape from aggressive cage mates.
Submissive behavior is exhibited in some species through presentation of the hindquarters to the dominant figure. In group housed monkeys this behavior helps maintain the pecking order and minimizes fighting. Grooming is a characteristic habit of some primates and serves to sustain physical contact and diminish tension.
