Description:Males of most anuran species use acoustic communication to attract females. Rana aurora (Northern Red-legged Frog) is one of a few anuran species that calls underwater, making it difficult to survey using traditional visual and auditory methods. R. aurora are experiencing significant population declines and are listed as a sensitive species in Oregon. Lack of information on basic life-history strategies may limit conservation efforts. This study explored calling behavior and breeding phenology of R. aurora by quantifying seasonal and diel calling patterns. An audio recorder with an underwater microphone (called a hydrophone) was used to capture underwater
