Habits and Reproduction

  • Breed early in the season beginning in late March and generally breed in areas where the water is at least 10 cm deep.
  • Rasping breeding calls “cre-ee-ee-eek” sounds like a thumbnail drawn over the teeth of a small comb.
  • Remain in the tadpole stage for approximately two months and live no more than a year as an adult.
  • Secretive and rarely seen outside of breeding season.
  • Forage for food in fields and open forest.
  • Hibernate beneath leaf litter, logs or underground.

Habitat

  • Meadows and forest openings around vernal pools (typically are dry later in the season and do not support fish).

Threats

  • Loss of breeding sites and effects of pollutants such as herbicide and pesticides.

Conservation Actions

  • Learn the call of the chorus frog and listen for them in early spring. Please report the areas where you hear them.
  • Vernal pools are important habitat for many amphibian species. If you have them on your property, please try to leave them in their natural state.
