The keeping of wild animal exhibits in the Hong Kong Zoological and Botanical Gardens can be traced as early as in 1876. At that time, birds and mammals were kept in small numbers in very primitive structures purely for entertainment purposes. 
Following the major expansion in the mid-1970s, emphasis were then directed to the techniques in captive breeding and conservation breeding programmes. Today, our mission is developed to guide the activities for zoological collection:-  
(a) To foster an understanding of and appreciation for all living things through education, conservation, research programmes and exhibition; and
(b) To develop appreciation for the interdependence of nature.
At present, about half of the Garden's land is dedicated to the keeping of zoological exhibits. About 200 birds, 70 mammals and 30 reptiles are being housed in about 40 enclosures.
