Not all the victims contained diamonds, but some were fantastically rich; in one bird's gizzard 63 diamonds were found. The fastest of the smaller African wildcats, caracals are supreme hunters. [78] When the common ostrich is experiencing heat stress from the environment the air flow is considered turbulent.
