    Habitat

  • Areas of sandy, loose soil in or adjacent to forests.
  • Typically observed during breeding, in shallow depressions or vernal wetlands in open areas (pastures, fields) adjacent to woods.
  • Primarily found on Coastal Plain.
  • How to Find

  • Listen for their distinctive explosive grunt call “geeoo”, likened to the sound of young crows, on nights during or following torrential rains, with air temperatures 50o F.
  • They are explosive breeders, calling only 2-5 nights per year at any one site.
  • Breeding can occur from March-September, but usually from late March to mid-May.
