Sociable weaver birds live in Africa's Kalahari Desert, where they build their huge nests on sparse trees and telephone poles. These nests can be more than 6 meters long and weigh more than 900 kilograms. When they become too big or waterlogged, they can cause the tree beneath them to collapse. Some nests are even more than a century old, with generations of weaver birds occupying the individual chambers.
