Eland live in large herds, usually numbering around 60-75 individuals, though herds in the hundreds have also been witnessed. They have a pretty complex social structure, with three separate group types observed. There are Female Groups, which are predictably full of females. These groups travel large distances. The Male Groups, in contrast, are sedentary. Lastly, there are Nursery Groups, which are made up of females with offspring, calves, and not quite mature adults. As calves age, their mothers leave to rejoin Female Groups. Eventually, the young Eland will be old enough to move on to a different group as well. Eland can live 15-25 years in the wild.
