    Habitats

  • Woodlands, particularly areas recently cut-over with brushy second growth, near shallow temporary or semi-permanent bodies of water where they call from during breeding season.
  • Considerable habitat overlap with chorus frogs.
  • How to Find

  • Listen for the call from February to March, a piercing high single whistle “peep” repeated about every second.
  • A large chorus from a distance has been likened to the sound of sleigh bells.
  • Look on clumps of grasses and on the branches of low shrubs.
  • Best method to find is to triangulate with flashlights on same calling individual.
  • Calls day or night.
