A fish eagle swoops over the water to grab a fish in its talons and then flies to its nest. Nearby are a martial eagle, a black eagle, an Egyptian vulture and hundreds of other birds. With an estimated 400 species of birds on an idyllic spot on Zimbabwe’s Lake Chivero, about 40 kilometers (25 miles) south of Harare, the Kuimba Shiri bird sanctuary has been drawing tourists for more than 15 years.
