Did you know that male mice sing to attract the ladies?
We can’t hear their songs because they’re way too high for our audio range but each species has its own song and they vary the tunes to fit the social setting.
I learned about this in April’s Audubon news when they highlighted Duke University’s research into mouse songs. The article included this video of two mouse songs with the audio track digitally lowered so we can hear it.
First a researcher places fresh female urine in the male’s enclosure. Mr. Mouse can smell her but can’t see her so he sings a loud and complex song. Next they put a female in the male’s enclosure. When he finds her (why does it take so long?) he snuggles up and sings a softer, simpler song.
What do the lady mice think? When placed alone in an enclosure with a speaker playing male songs, most females stay close to the speaker when the complex songs play. Perhaps those songs say “Come hither!”

p.s. At 50kHz we humans can’t hear mice sing … but cats can!

The title is a reference to “Frog Went A-Courting” in which Frog sings to woo Miss Mouse.
