5-6-2019 MOREMI CAMP, BOTSWANA - SOUTHERN LION (FEMALE) (Panthera leo ssp. melanochaita)

Panthera leo melanochaita is a lion subspecies in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea, and are threatened by loss of habitat and prey base, killing by local people in retaliation for loss of livestock, and in several countries also by trophy hunting. Since the turn of the 21st century, lion populations in intensively managed protected areas in Botswana, Namibia, South Africa and Zimbabwe have increased, but declined in East African range countries. In 2005, a Lion Conservation Strategy was developed for East and Southern Africa.

Results of a phylogeographic study indicate that lion populations in southern and eastern Africa form a major clade distinct from lion populations in West Africa, Central Africa and Asia. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely P. l. leo and P. l. melanochaita. Within P. l. melanochaita three subclades are clearly distinguishable. One from northeastern Africa, another one from southwestern Africa and a third one from southeastern Africa.

The type specimen for P. l. melanochaita was a black-maned lion from the Cape of Good Hope, known as the Cape lion. Phylogeographic analysis of lion samples from Gabon and the Republic of the Congo indicate their close genetic relation to P. l. melanochaita samples from Namibia and Botswana. It has been referred to as the Southern lion, Southern African lion, East-Southern African lion and the "southern subspecies". Lions usually hunt in groups and prey foremost on ungulates such as gemsbok (Oryx gazella), Cape buffalo (Syncerus caffer), blue wildebeest (Connochaetes taurinus), giraffe (Giraffa camelopardalis), common eland (Tragelaphus oryx), greater kudu (T. strepsiceros), nyala (T. angasii), roan antelope (Hippotragus equinus), sable antelope (H. niger), plains zebra (Equus quagga), bushpig (Potamochoerus larvatus), common warthog (Phacochoerus africanus), hartebeest (Alcephalus buselaphus), common tsessebe (Damaliscus lunatus), waterbuck (Kobus ellipsiprymnus), kob (K. kob) and Thomson's gazelle (Eudorcas thomsonii). 

Their prey is usually in the range of 190–550 kg (420–1,210 pounds). In the Serengeti National Park, lions were observed to also scavenge on carrion of animals that were killed by other predators, or died from natural causes. They kept a constant lookout for circling vultures, apparently being aware that vultures indicate a dead animal.[80] Faeces of lions collected near waterholes in Hwange National Park also contained remains of climbing mice (Dendromus) and common mice (Mus).

In Botswana's Chobe National Park, lions also prey on young and subadult African bush elephants (Loxodonta africana). They successfully attacked 74 elephants between 1993 and 1996, of which 26 were older than nine years, and one bull over 15 years old. In October 2005, a pride of up to 30 lions killed eight African bush elephants that were between four and eleven years old.
