The martial eagle (Polemaetus bellicosus) is a large eagle native to sub-Saharan Africa. A species of the booted eagle subfamily (Aquilinae), it has feathering over its tarsus. One of the largest and most powerful species of booted eagle, it is a fairly opportunistic predator that varies its prey selection between mammals, birds and reptiles. It is one of a few eagle species known to hunt primarily from a high soar, by stooping on its quarry. Currently, the species is classified as endangered by the International Union for Conservation of Nature. This martial eagle was photographed in the Matetsi safari area in Zimbabwe.Photograph credit: Charles J. Sharp
