Cool Facts

  • The male Rock Wren is a truly remarkable singer and can have a large song repertoire of 100 or more song types, many of which seem to be learned from neighbors.
  • The Rock Wren usually builds a pavement or walkway of small, flat stones or pebbles that leads to the nest cavity. The nest is usually located in a rock crevice out of sight, but the pavement may give away the nest’s location. The function of this pavement is unknown.
  • The Rock Wren is not known to drink water, but instead gets all it needs from its food. Even five birds kept in captivity did not drink water when it was available.



Arid or semiarid areas with exposed rock; desert to alpine habitats.
