Wildlife Sanctuary


Today, the wildlife sanctuary is home to Sally and another hippo Potty, two male elands, 2 female buffaloes and a congregation of water birds including a flock of Egyptian geese and crowned crane that have found a home in the habitat. It was not by pure coincidence that a hippo was introduced in the large pond.

Home of the hippos

The wildlife sanctuary continues to be the home of the oldest hippos in Haller Park. Sally, was introduced at Bamburi Nature Trail in 1976 and was later joined by Potty in 1986. After being introduced into a separate enclosure neighbouring Sally's, it took 3 months before they seemed comfortable with one another. Since then, they have been inseparable. Although they mate, Sally and Potty have never produced any offspring.


The most famous/Popular Hippo in Haller Park is Owen!- due to international coverage and publications done on him following the Tsumani and extra ordinary-unlikely friendship/ relationship with the tortoise (Mzee), a relationship that lasted till 2006 when they were separated. Today Owen lives happily with Cleopatra lives in their enclosure near the Haller Park main gate opposite Owls cages

About the hippopotamus

Hippos are nocturnal and therefore graze mainly at night returning to the ponds where they disperse their droppings and urine in the water. By wading and swimming in the pond they contribute to a vital activity that is of great ecological importance. They help restore the nutrients and fertilize the water so that plankton can grow. The plankton is important fish food. In turn the hippos aerate the water and prevent the build up of toxic gases forming an important link to the integrated aquaculture system.
