This group is confined to sub-Saharan Africa, and is the only bird order confined entirely to that continent.They are slender greyish or brown birds with soft, hairlike body feathers. They are typically about 10 cm in body length, with a long, thin, tail a further 20–24 cm in length, and weigh 45–55 grams
They are arboreal and scurry through the leaves like rodents, in search of berries, fruit and buds. This habit, and their legs, gives rise to the group's English name. They are acrobatic, and can feed upside down.
