Brimley's Chorus Frog vs Cajun Chorus Frog
Brimley's chorus frog and the Cajun chorus frog both belong to a genus notorious for look-alike species, and each one owes its identity as a distinct species to a geographically narrow range rather than to any dramatic difference in appearance.

Brimley's Chorus Frog vs Cajun Chorus Frog: common questions
What sets Brimley's chorus frog apart from the Cajun chorus frog?
Range is the clearest distinction — Brimley's chorus frog is confined to a narrow strip of the Atlantic coastal plain from Virginia to Georgia, while the Cajun chorus frog occupies the western Gulf Coast states, and the two ranges do not overlap, making location far more useful for identification than call or appearance alone.
Why was the Cajun chorus frog only recently recognised as its own species?
The Cajun chorus frog was formerly classified as part of the upland chorus frog until genetic and bioacoustic evidence showed the western Gulf Coast population was genuinely distinct, a taxonomic split that Brimley's chorus frog, long recognised as its own species, never had to go through.
When do these two chorus frogs breed?
The Cajun chorus frog typically breeds in winter and early spring, well before many other frogs become active, while Brimley's chorus frog follows a more typical chorus-frog breeding schedule tied to its Atlantic coastal plain ditches and ponds.
