5 pages in length. In Ultrasonic Songs of Male Mice, Timothy E. Holy and Zhongsheng Guo seek to determine the extent to which male mice emit ultrasonic songs when in the vicinity of female mice. They discover, through scientific methodology, the conditions upon which this occurs, the varied nature of syllables used and the vastly superior scale upon which these songs are delivered. The hypothesis, therefore, seeks to determine the equivalency to what equates to song, as well as the level of diversity with regard to the individual male mouse, which results indicate a "small but significant difference in syllable usage and the temporal structure of their songs" (Holy et al, 2005, p. 386), suggesting how mice communication may hold myriad more complexity than has been understood.

The hypothesis, therefore, seeks to determine the equivalency to what equates to song, as well as the level of diversity with regard to the individual male mouse, which results
indicate a "small but significant difference in syllable usage and the temporal structure of their songs" (Holy et al, 2005, p. 386), suggesting how mice communication may hold myriad more
complexity than has been understood. "...It seems likely that song is more widely distributed than we currently appreciate. While the neural and motor mechanisms used to produce song
and other communication sounds vary across species, recent work has indicated some commonality at the molecular level..." (Holy et al, 2005, p. 386).
The operational variables include the use of one-month-old male mice who were maintained on a schedule of light and dark for twelve hours, respectively, each day; at two months
of age they were housed individually. When the males were no less than one hundred days old, trials commenced with each of four consecutive day having two 3-minute "social
experiences" (Holy et al, 2005, p. 386), the difference being that one of the sessions was with a female and the other with a castrated male awash with intact male
urine. The studys outcome is consistent with the hypothesis, inasmuch as results indicate how the ultrasonic vocalizations "have the characteristics of song" (Holy et al, 2005, p. 386) attributable
to such other animals as birds, frogs and insects. Moreover, the complexity and diversity of these songs have proven to surpass that of the monosyllabic form of insects and
