Weaverbirds design and build intricate nests

Narrated by David Attenborough, watch these weaverbirds, or Ploceidae, design and build intricate nests to woo mates. They start with a simple knot, and then it’s all about their experience, creativity, and fluttering wings. Weaverbird nest-building, via Wikipedia:

Materials used for building nests include fine leaf fibers, grass, and twigs. Many species weave very fine nests using thin strands of leaf fiber, though some, like the buffalo-weavers, form massive untidy stick nests in their colonies, which may have spherical woven nests within. The sociable weavers of Africa build apartment-house nests, in which 100 to 300 pairs have separate flask-shaped chambers entered by tubes at the bottom. The sparrow weavers live in family units that employ cooperative breeding. Most species weave nests that have narrow entrances, facing downward.
