Now that the song "The Fox" is a bona fide hit (40 million YouTube views) and Ylvis has been on The Ellen Degeneres Show, the question remains: What does the fox say? We don't know!
Fortunately, some people do, and they’ve recorded foxes making those sounds. Wired points us to the Cornell Lab of Ornithology’s Macaulay Library, which catalogs audio and video of thousands of species.
So, what does the fox say? Like other animals, foxes have a lot of different calls that they use for different situations.
...none of which roll off the tongue as easily as “Gering-ding-ding-ding-ringerdingering.”
Hear audio clips of what foxes actually sound like, which vary depending on species and purpose, but all defy translation into human language. Do not neglect to read the comments at mental_floss. Link
