Hippopotamus and Tick birds.
1962 Luangwa Valley Game Reserve.
These hippo lived near the lodge where I spent the night.
All day they laze and wallow in the pool. At night they graze on the fresh green grass around the lodge!
Two Tick birds are perched on the big one in the photo below. They feed on ticks that in turn feed on open wounds.
These ticks often enlarge the wounds for a better supply.
Tick birds are thus not popular with farmers as they also practice this on cattle.
