Mouse Serenade?
This story not only has singing mice but it turns out the male “wee beasties” are actually crooning to their female counterparts. Who knew mice could sing? This does, however, explain the popularity of certain nameless pop groups ...
Researchers Add Mice To List Of Creatures That Sing In The Presence Of Mates
Scientists have known for decades that female lab mice or their pheromones cause male lab mice to make ultrasonic vocalizations. But a new paper from researchers at Washington University School of Medicine in St. Louis establishes for the first time that the utterances of the male mice are songs.
This finding, to be published Nov. 1 online by the journal Public Library of Science Biology, adds mice to the roster of creatures that croon in the presence of the opposite sex, including songbirds, whales and some insects.
“In the literature, there’s a hierarchy of different definitions for what qualifies as a song, but there are usually two main properties,” says lead author Timothy E. Holy, Ph.D., assistant professor of neurobiology and anatomy. “One is that there should be some syllabic diversity—recognizably distinct categories of sound, instead of just one sound repeated over and over. And there should be some temporal regularity—motifs and themes that recur from time to time, like the melodic hook in a catchy tune.”
The new study shows that mouse song has both qualities, although Holy notes that the ability of lab mice to craft motifs and themes isn’t quite on a par with that of master songsmiths like birds.
“Perhaps the best analogy for mouse song would be the song of juvenile birds, who put forth what you might call proto-motifs and themes,” he explains. “It’s not yet clear whether singing conveys an advantage to male mice during courtship, as it appears to do in birds.”

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:
It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.

Oh, and here's some kind of visitor flag counter thingy. Hey, all the cool blogs have one, so I should too. The Visitors Online thingy up at the top doesn't count anything, but it looks neat. It had better, since I paid actual money for it.
