This week we learned a bit about Brazilian torrent frogs. It turns out they'll do a lot to get attention, when it comes time for mating. They'll wave their arms around, squeal, do a bit of toe-tapping and, yes, even some singing. They might be the most complex communicators among amphibians. In honor of the little hopper, let's take a look at a few other animals out there that have some, perhaps unexpected, vocal chops.Frog Sings Like A Bird, Bobs Head For Mates
A few years back, some enterprising scientists decided to give helium to gibbons for them to inhale, to test their physiology against that of humans. They found that gibbons share the same vocal structures as humans, and that the primates use the same techniques as opera singers when they make their calls.Gibbons on Helium Trill Like Opera Singers
Whales, such as orcas, and dolphins are well known for their sounds. Beluga whales, though, really earn the moniker "sea canaries" for their vocalizations. They're among the most "talkative" of the cetaceans, using calls and squeaks and squeals at such a high frequency that they can sound like birds. They use their vocals to communicate, navigate, and mate.Whales, Dolphins Experience Joy, Squeal With Delight
We should tip our hats to birds, of course. They're the real singing champs. After all, we don't throw open our windows in the spring and hope the frogs are singing.Birds Tap Their Beaks In Rhythm To Songs
Here's a crooner that might surprise you. We learned in the last year or so that mice modulate their songs based on whether or not a mate is in view. They'll sing louder when mates are smelled but not seen, and switch into Sinatra mode once a potential mate is in sight. Other mice, in the forests of Central America, will sing in high-pitched opera style to mark their territory.
