text: The thorn birds (Phacellodomus), as well as many other Furnariidae, build huge nests of twigs suspended from the ends of tree branches; these nests, which may be more than 2 metres (nearly 7 feet) long and contain many compartments, are used by only a single nesting pair, sometimes with nonbreeding helpers (probably the young of the previous season).
