These are vocalizations from what was presumed to be a male muskrat attempting to copulate with a female muskrat. Rain is heard falling as the portion of the recording with vocalizations progresses. Following the vocalizations, one hears a sequence of water sound effects as the muskrats go in and out of the entrance of the burrow, the entrance underwater or partially submerged and thus having a water jug like sound. These muskrat were in a deep pool that remained in an otherwise largely dry stream bed. The burrow that these animals were going in and out of was in the cut stream bank (~2.5-3 meters high)on the southern edge of the pool. The stream runs along side southern edge of Red Rocks Road. The location was east of and very close to the California-Nevada line. I heard these vocalizations being given spontaneously and approached the pool for the high bank on the south edge of the stream. An MS stereo pair was slowly lowered over the edge of the stream bank so that it was suspended over the edge of the pool near the burrow, thereby capturing the vocalizations as one of the two swimming muskrats attempted several times to mount the other near the burrow. The estimated distance between the muskrats and the suspended MS stereo pair ranged between a 1.5 to 5 meters. The basic habitat is small canyon with scattered juniper.
