Serengeti: Great plains

Suspended in a cloudless sky, an African white-backed vulture soars above a huddled mass. With wingtips outspread like fingers, it lowers dagger-like talons and arcs its back, landing in savannah grasses stained red with blood. Cracking bones and a satisfied hissing ripple through the Serengeti as scavengers greedily feed on the corpse of a wildebeest.
