Guinea Fowl are the African representatives of the pheasants, from which they differ in that the plumage of both sexes is alike. The origin of the domesticated stock is <i>Numida meleagris</i>, from W. Africa. A number of other species occur in other parts of Africa. In the black guinea fowl (<i>Phasidus niger</i>), which ranges from Cape Lopez to Loango, spurs are present in the male as in pheasants. Guinea fowl are nearly all gregarious, are ground feeders, and roost in trees. Most species seek to escape danger by running rather than by flying. As in the turkeys, parts of the head and neck are without feathers, and these bare patches are often highly colored.

The ground squirrels are the members of the Sciuridae most closely related to the genus Marmota. They make up the tribe Marmotini in the large and mainly terrestrial squirrel subfamily Xerinae, and containing six living genera. The ground squirrel is especially renowned for its tendency to rise up on its hind legs. It does this whenever it senses nearby danger, or when it must see over tall grasses. The squirrel then curls its paws flat against its chest and sends a screeching call to warn other family members about the presence of predators
