Barking treefrog

Dryophytes gratiosus

North America's largest native treefrog, spotted and plump, whose call sounds like a distant dog.

Behaviour

Barking treefrogs spend much of their time high in trees and burrow into sand in dry weather. They gather to breed in fish-free ponds after heavy summer rain.

Why they matter

They depend on seasonal ponds that dry out and hold no fish, a habitat easily lost when low ground is drained or filled.

Reproduction and lifecycle

Eggs — Laid singly on the bottom of shallow ponds
Hatching — In a few days
Tadpoles — Change into frogs in about 6 to 10 weeks
Maturity — Within a year or two
Lifespan — Several years
Calling — After summer rains

Living around people

  • Keeping seasonal ponds and wet hollows unfilled keeps these frogs breeding.

Misconceptions

  • A frog that barks must be something else. The barking treefrog's name is its call.
