Maasai Mara was seemingly even higher, at a median between the average prey sizes for each sex of martial eagle at approximately . Despite perhaps a majority of prey for this species weighing less than , martial eagles regular prey size range is claimed at up to . There is some evidence of prey partitioning (which can be potentially delineated both by prey species and body size of prey items taken) between the sexes. This is typical of raptors with pronounced size sexual dimorphism, as is the case in martial eagles. For instance, in populations where large adult monitor lizards are significant as prey, they only start to appear in prey remains at nests only after the female resumes hunting in the latter part of the breeding season. The species was the focus for a study using web sourced photography to explore the species' diet across its African range, this study revealed new insight into difference in prey composition between regions, and also revealed differences in prey composition between adult and sub-adult birds, with adults found to prey more frequently on bird prey than sub-adults. The sexual dimorphism of kills was verified in studies from the Great Rift Valley and Maasai Mara. One study stated that the mean weight of male kills was and that of females was . In Maasai Mara, the mean prey was significantly higher for both males, at about , and for females, at about . Mammals The most diverse class of prey in the diet as known are mammals, with over 90 mammalian prey species reported. In the Cape Province, the cape hare (Lepus capensis) reportedly dominates the prey selection, comprising about 53% of the foods selected. Other lagomorphs, namely the slightly smaller Smith's red rock hare (Pronolagus rupestris), mildly larger African savanna hare (Lepus microtis) and the much larger scrub hare (Lepus saxatilis), are not infrequently taken both in and outside of the Cape area. In Maasai Mara, the most regularly identified food, at 17.3% of 191 prey items (and particularly for male martial eagles at 23.9% of their kills), was found to be comprised by a mixture of cape and scrub hares, these in total weighing an estimated mean of . For the most part rodents are ignored as prey as they are probably too small despite martial eagles taking at times appreciable numbers of Cape (Xerus inauris) and unstriped ground squirrels (Xerus
