From July to October, the dry season, Tarangire National Park is teeming with animals as wildlife, including large elephant herds, do not stray far from the river bed. Elephants need between 100 and 300 litres of water a day to survive and the holes they dig in the sands of the river are the only source for hundreds of miles of kilometres around. These holes attract other animals, who drink the water after the elephants have had their fill. If all the herbivores are in Tarangire, the great lions and leopards will soon follow to get their dinner, as well. Tarangire National Park also provides great opportunities for birdwatching: being the nesting grounds for a large number of bird species. The largest flying bird in the world, the Kori Bustard is often spotted here. Hornbills, the yellow-collared Lovebird as also endemic to the area. There are options for night safaris and short walking safaris for travellers who wish to spend a few days in Tarangire National Park.
