The female of the montezuma oropendola of Central America builds one of the most elaborate nests in the animal kingdom. Using vines, the bird weaves a large basket-like nest that hangs from trees. The nests are anchored with the strongest vines, and bits of fibre and other vines are added as finishing touches. They are built in a group, forming a huge colony.
To keep away predators, nests are constructed on isolated trees and are suspended from the flimsy ends of the branches to deter monkeys. The oropendolas also take care to locate their nests inhabited by hornets!
