Both browsers and grazers, impalas will eat a variety of food from trees and the ground. They reproduce at a rate of 33%, which is why you are sure to find these antelope at Inverdoorn. They are incredibly territorial and exist within a harem system. Highly adaptable, they can exist almost anywhere which is why they are found in such vast abundance. During mating season, they can be heard calling with a strange roar-like call.
