Fun facts

  • It is one of the commonest hosts of the common cuckoo, even though its nest is ridiculously small to hold a chick of that size.
  • It shows extreme fidelity to the place where it was born or bred: year after year it is found occupying exactly the same patch of reeds.
  • The nest hangs suspended from green stems over shallow water, a structure built by the female alone.
