  • Prefers moist hillside forests and floodplains.

  • How to Find:
  • In Maryland, this frog is found only on the Allegheny Plateau of Allegany and Garrett Counties.

  • Listen for its high pitched trill, similar to the ascending notes produced by running a finger up a comb.

  • Distinguished from the Upland Chorus Frog by the shorter trill interval and its unique location.
