Zoo facts

700 million people

worldwide visit zoos each year.

27 endangered species

are housed at the Johannesburg Zoo.

The zoo successfully bred Siberian tiger cubs in April 2016

The global tiger population has declined dramatically to fewer than 4 000 in the wild.

There are probably only 1 500 ground hornbills in South Africa

Groups consist of two to nine birds. In each group there is usually only one breeding female. An average of one chick is raised to adulthood every nine years. The zoo is involved in hand-rearing a second hatched chick which would have ordinarily been abandoned once the first egg hatched. www.jhbzoo.org.za
