Native to sub-Saharan Africa and the Nile River Valley, the Egyptian goose has now settled in N. America, much of Europe, and parts of the Middle East. Although normally quite reserved and shy, males will become boisterous and aggressive during their breeding season to attract a female.

The speckled mousebird hangs belly to belly with others in its flock to keep warm while sleeping. After a meal — of toxic plants, clay, dirt, and peddles — a mousebird may hang upside down, exposing the black skin of its belly to the sun in order to warm up and aid digestion.

The common reed frog exhibits extreme variation in colour patterns — with some 50 recognised subspecies. Additionally, this frog changes the colour of its skin according to weather and temperature, turning pure white in the heat of the dry season.

The palm-nut vulture is unusual among vultures, in that about 70% of its diet is vegetarian — mostly consisting of palm nut fruits. It was once called the "vulturine fish eagle”, because of its eagle-like appearance and the way in which it hunts; swooping to the water's surface to grab fish.

The dwarf mongoose — Africa's smallest carnivore — uses old termite mounds as shelter, living with a family of up to 30 individuals. When foraging for insects, these mongooses work together with hornbills; the mongooses flush out insects and the hornbills watch for aerial dangers.
