What is the Southern Leopard Frog's call?

"Chu-h-h-h-huck, chu-h-h-h-huck, chu-h-h-h-huck" is the call of the Southern Leopard Frog (Rana sphenocephala, Lithobates sphenocephalus).

Specifically, the voice of the Southern Leopard Frog is a rapidly repeated series of 5-10 guttural stutters. Its rate slows as temperatures drop. The call sounds quite a bit like the call of the Plains Leopard Frog (R. blairi). It becomes faster in rate, higher in pitch and rattling in quality as temperatures rise. The call is heard during the spring in the northern United States of America and any time after heavy rains in the South.
