WASHINGTON (Reuters) - "Some people want to fill the world with silly love songs. And what's wrong with that? I'd like to know," Paul McCartney sings in his 1976 song "Silly Love Songs." Mice might agree.
It turns out male mice actually use ultrasonic "love songs" to woo females, using different tunes when they smell but do not see a female and when they lay eyes on their potential lady love, scientists said on Wednesday.
