As it does for many other vertebrates, the mating season for the Pacific midshipman fish brings changes in behaviors. Males migrate to their nesting territory and begin to hum, producing a sound that their female counterparts find irresistible (although human ears have likened the sound to that of a motorboat). Sisneros et al. (see the Perspective by Zakon) now show that the acoustic sensitivity of the inner ear in females is actually adjusted to better match the frequencies put out by the mating hum in response to seasonal changes in circulating steroid hormones. Thus, the effectiveness of the male's siren song is enhanced by seasonally tuned hearing in females.
