Deskripsi
<p>We report descriptive information on the vocalizations of two species of rodents, analyzing and describing their spectral and temporal variability. <em>Reithrodontomys soderstromi</em> emits a nearly constant sounding whistle with a mean dominant frequency of 10.16 ± 0.20 kHz. The vocalizations of <em>Thomasomys paramorum</em> resemble clicks with frequency modulations with a mean dominant frequency of 1.74 ± 0.10 kHz and generates a harmonic whose mean frequency is 3.64 ± 0.24 kHz.</p>
