What is the Cajun Chorus Frog's call?

Answer:
"Crrreeeeek" is the call of the Cajun Chorus Frog (Pseudacris fouquettei).

Specifically, the voice of the Cajun Chorus Frog is a clicking trill that is made very quickly. In fact, each trill lasts just a bit more than a second. Its voice is very similar to that of the Southern Chorus Frog (P. nigrita), whose range is overlapping.
