Behaviour

Upland chorus frogs breed in winter in shallow, temporary water, often while the nights are near freezing.

Why they matter

They use pools too short-lived for fish, so their eggs are safe from fish predators, and their tadpoles feed many animals.

Reproduction and lifecycle

Eggs — Small clusters on plants in shallow pools
Hatching — In a week or two
Tadpoles — Change into frogs in about 2 months
Maturity — Within a year
Lifespan — A few years
Calling — In winter

Living around people

  • Flooded fields and ditches in winter are its breeding places; leaving them helps.

Misconceptions

  • Frogs are silent in winter. Chorus frogs call loudest in winter in Georgia.
