The pine woodlands of easter Texas, Louisiana, western Mississippi, Arkansas, and eastern Oklahoma are home to the Cajun Chorus Frog (Pseudacris fouquettei). It is sometimes still known by its older names of the Upland Chorus Frog (P. feriarum) or Western Chorus Frog (P. triseriata). They call during the early spring and into the fall any time there is appreciable rain in their range. They will call from flooded areas in the forest, along flooded roadsides, or flooded areas in agricultural fields.
Their call sounds like someone running their fingernail slowly across a comb. This one was calling from a suburban park in Little Rock, Arkansas on a cool March night.
Here is a larger chorus of them from Holla Bend National Wildlife Refuge, Arkansas.
