This is a secretarybird, the most alien-looking bird I have ever seen in person. It stands about four feet tall, and hunts lizards, snakes, and other small animals by walking along looking at the ground. It can strike prey with its beak, but often uses its long legs and claws.
I have read that secretarybirds often hunt in pairs or groups, but the two I saw were solitary.
The horns on this cape buffalo skull have been colonized by the horn moth (Ceratophaga vastella), a relative of the clothes moth. The caterpillars are able to digest the keratin in old horns, and the protuberances you see are cases or towers the caterpillars build using their own feces, as protection from predators.
This extra-small hyena cub was up and about first thing in the morning, while its litter mates slept in the den below. Hyena cubs have very dark fur at birth, and develop their distinctive spots or stripes (depending on the species) as they grow.
This little giraffe absolutely could not stand having a bird aboard. She tried walking fast, wiggling her neck, swishing her tail around, and rubbing her neck against mom, but the oxpecker was bound and determined to stay put.
This baby was at least two days old, and steadier on her feet than the new baby giraffe we saw a couple of days later.
