The use of mixed-species exhibits in zoological parks may influence the types and rates of interactions between individuals housed in such enclosures. Inter-and intraspecific behavioral interactions were observed for three species of lemurs (ring-tailed lemur, Lemur catta; black lemur, Eulemur macaco macaco; and black-and-white ruffed leumur, Varecia variegata variegata; in an enclosure designed to simulate characteristics of their natural habitat. Intraspecific interactions occurred more frequently than interspecific interactions, and little aggression was observed, either between or within species. Intraspecific interactions among black lemurs increased with decreasing ambient temperature. Black lemurs performed more intraspecific mutual contacts than either agonistic behaviors or …

We examined the responsiveness of adult gray rat snakes to avian prey in enclosures that simulated natural habitat conditions. Subjects searched for arboreal nest contents in the presence or absence of a bird model flown so as to simulate avian provisioning behavior. In the absence of the model, gray rat snake latency to capture prey was over 92 % greater than when searching for nest contents with the model. Snakes responded to model flight by turning their heads in the direction of its movement. We conclude that gray rat snakes perceive relatively distant visual cues from prey, and that nest …
