Singing Mice and Brain Chemistry
Shirlockc writes "The Public Library of Science has a research article on how male mice actually sing in the presence of females. They actually posted some of the audios adjusted for human ears as these songs are ultrasonic. The authors are comparing these warbles to bird songs. The songs are quite complex so do the mice learn them and/or improve on them? This can be a potential model for investigating how brain chemistry works during learning."
This should not be a surprise. Mice are truly the smartest most intelligent species to inhabit the Earth, followed by dolphins, then humans.
I've been emitting high-pitched squeals whenever attractive women come near me for years. Why does nobody call it a "song" then? ;(
Now we just need to work on reverse-engineering their secret ultrasonic communications so that we can find out what they plan to do with us.

So why do the male mice sing to the females, eh? I mean, it's not like they need sound to find each other or tell the pitchers from the catchers -- they can sniff each other out in the total dark, et cetera.

Why would natural selection push male mice to develop this talent?
I sure don't know, but just for amusement I'll propose something along the lines of the OP's comment: suppose we argue an important characteristic of mice is that they are damn clever for their size. Seems likely they're a lot smarter, for example, than snakes or lizards or even birds of equivalent mass. Maybe they need smarts to succeed at a lifetime of scampering and hiding and thieving bits of food from larger predators.
If this is so, maybe it makes sense that the smartest males want to advertise their intelligence, and females are interested in listening to those ads, so that they can pick out good genes for the pups.
Now, clearly it takes brains to learn a complex song, spice it up with a couple of individual flourishes, and memorize it. So maybe what these mice fellas are doing by singing is advertising how smart they are. And maybe the girl mice by listening in are evaluating the sexy braininess of boy mice as it's expressed in their composition.
It would be, in essence, the auditory equivalent of posting clever comments on
