  • Flapping involves two stages: the down-stroke, which provides the majority of the thrust, and the up-stroke, which can also (depending on the bird's wings) provide some thrust.
  • A tailorbird makes its nest out of two or three large leaves. It uses its sharp beak like a needle to sew and join the leaves together with bits of wool, cotton or spider's web. The nest is lined with grass, thread and dried grass to keep it warm and cozy.
