African buffalo herds vote with their heads
Syncerus caffer is sub-Saharan Africa's sole living Syncerus species—a massive bovid with a fused horn boss in big bulls. Herds can top a thousand on floodplains. Before dusk, resting cows stand, look a direction, then lie down again; when enough point the same way, the group moves. Power has not spared it from Near Threatened status.
Anders Sparrman described the species in 1779. Four subspecies are usually listed: Cape, West African savanna, Central African savanna, and forest buffalo. Mitochondrial DNA sorts Cape buffalo of East and southern Africa into one cluster and the other three into another, a split that geneticists link to isolation in savanna refugia roughly one hundred thirty to three hundred thousand years ago. Syncerus and Asian Bubalus parted some six to nine point eight million years ago; living African buffalo emerged about five hundred thousand to one million years ago. Cape bulls weigh six hundred fifty to nine hundred kilograms; forest buffalo, the dwarf form, stand only one hundred to one hundred thirty centimetres at the shoulder.
Social life is female-centred. Cows stay with the herd for life; savanna males peel off at four or five into bachelor bands before contesting mating rights, then may leave again when worn down. Gestation lasts about three hundred forty days; weaning runs ten to eighteen months. Dominant bulls lift the head and tip the nose down as a threat; subordinates lower theirs. Mixed herds are fission-fusion societies, splitting more in the wet season. Home ranges stretch from about four point six to three hundred fifty square kilometres, while bachelor patches may be under four. Permanent water ideally lies within twenty to forty kilometres.
Since the nineteenth century, poaching, climate pressure, farming, and disease have carved huge holes in a former range that needed roughly two hundred fifty millimetres of annual rain. Most savanna herds now cling to parks and adjacent hunting zones. As of 2019 the IUCN called the species Near Threatened, estimating three hundred ninety-eight thousand to four hundred one thousand mature animals. Few predators tackle healthy adults, yet calves remain vulnerable—and human encroachment does what lions rarely can.
