CARE OF CAPTIVE ANIMALS — WALKER 347 



Others of the same genus have been kept in the National Zoological Park for 

 more than 2 years. The author's bat and those kept in the National Zoological 

 Park have been fed almost exclusively on mealworms. Other people have had 

 fair success when they fed various insects or meat. Cheese, cream, and dog 

 food have likewise been found satisfactory. It would be a good plan to offer 

 well-ripened bananas and other soft fruit to any captive tropical bat as some of 

 them probably consume such material in the wild, in addition to their principal 

 diet of insects. Some of the insectivorous bats are known to be carnivorous, 

 killing and eating other bats and small birds. Some also eat flower petals. 

 Water should be available at all times, as they drink frequently and copiously. 

 A slightly moist atmosphere appears to be favorable to all bats, and many are 

 inhabitants of the exceedingly humid Tropics. If the bat is to remain active, 

 the temperature should not fall much below 70", as bats either hibernate or 

 migrate to avoid cold weather. If they are to hibernate, they should be 

 maintained in a temperature of between 40° and 50° with very high humidity. 



VAMPIRE and FALSE VAMPIRE BATS (Desmodontidae). Can be success- 

 fully kept when fed defibrinated blood, or fresh uncoagulated blood. Keep in 

 uniformly warm temperature. 



FISH-EATING BATS (Noctilionidae). Bats of this family catch small fish 

 and perhaps insects from the surface of the water. Try feeding tiny fish or 

 small pieces of fish, insects, meat. They may also eat some fruits. 



LEMURS, MONKEYS, APES (PRIMATES) 



Most monkeys do not survive chilling, but a few can withstand moderate 

 winter weather. Some individuals of species from the Tropics become hardy 

 and spend much time outdoors in winter if they are given the opportunity. 



AYE ATE (Daubentoniidae). An inhabitant of Madagascar, uncommon in. 

 the wild and exceedingly rare in captivity. Apparently feeds mainly on insects, 

 but probably also eats fruit. Natives say it eats bamboo. Try feeding insects, 

 ground meat, eggs, fruit, leaves. 



TARSIUS (Tarsiidae). Feeds mainly on insects, and probably also eats fruit. 

 Try feeding insects, meat (raw and cooked), eggs, fruit, some soft green leaves 

 such as lettuce. 



LORIS, SLOW LORIS, POTTO, GALAGOS, and LEMURS (Nycticebidae). 

 Apparently omnivorous in the wild. Feed insects, meat both raw and cooked, 

 eggs, fruit, green vegetation, seeds, milk, bread. 



MARMOSETS (Callitrichidae), HOWLING MONKEYS (Alouattidae), NIGHT 

 MONKEYS (Aotidae), CACAJOUS, OUKARIS, SQUIRREL MONKEYS, SPIDER 

 MONKEYS, WOOLLY MONKEYS, CAPUCHINS (Cebidae), BABOONS, 

 MACAQUES, VERVETS, GRIVETS, PATAS, LANGURS, and COLOBUS (Cer- 

 copithecidae). Almost omnivorous in the wild. Feed the widest possible 

 variety of fruits, vegetables, lettuce, cabbage, kale, sweet potatoes and other 

 root vegetables, meat (cooked and raw), eggs, bread, milk, leaves, seeds and nuts 

 that are not too hard for them to open. The langurs and colobus monkeys are 

 primarily leaf eaters and will consume a higher proportion of leaves of a wide 

 variety than most of the other monkeys. It is well to vary the diet from day 

 to day. 



GIBBONS (Hylobatidae), ORANGS, CHIMPANZEES, and GORILLAS 

 (Pongiidae). Feed similarly to the preceding families. Young animals should 

 be given practically the same care as babies and young children.
