Glass frogs that live near loud streams add to mating calls with the flap of a hand, a wave of a foot, or a bob of the head to attract a mate, a new study shows.
Researchers have documented these frogs that “dance” near rushing streams where noise can obscure those crucial love songs in the rainforests of India, Borneo, Brazil, and, now, Ecuador.
Conservation ecologist Rebecca Brunner, a PhD candidate at the University of California, Berkeley, discovered that the glass frog
Sachatamia orejuela can join the list of species that make use of visual cues in response to their acoustic environments. This is the first time researchers have observed a member of the glass frog family (
Well, hello there: Glass frogs ‘wave’ to communicate near noisy waterfalls
A researcher discovered that an obscure species of nocturnal glass frog, Sachatamia orejuela, uses visual signaling as well as acoustical calls to communicate within their environment.
Other frog species are known to communicate visually, although they are unrelated to S. orejuela and are found on different continents.
A recent paper on the discovery also provides the first known description of the acoustical call of S. orejuela, endemic to Ecuador and Colombia.
Becca Brunner was standing chest-deep in an Ecuadoran rainforest stream, holding up audio equipment as she recorded the high-pitched call of an elusive glass frog. But then she encountered something unexpected: the frog was fluttering its front and back legs as well as bobbing its head.
These Glass Frogs that Live Near Noisy Waterfalls Wave Hello, Bob Heads to Attract Potential Mates

While humans take the best selfies and write the wittiest captions in their dating app’s bio to attract other humans, animals in the wild have to resort to some weird techniques to find a partner.
Some birds dance and showcase their plumage, some animals sing, but one particular frog species has been found to use a very human-like gesture for interaction- waving hello!
Sachatamia orejuela, a kind of glass frog, has been observed to simply wave over to attract a mate. They usually live near loud streams or gushing waterfalls. The usual method in frogs is to croak when initiating a mating call, but due to the glass frog’s surrounding, any croaks would be drowned by the sounds of water. So, when these frogs spot a potential mate, they wave them over either by flapping a hand or bobbing their head. These “dancing” frogs have been observed near streams and waterfa
When it comes to attracting a mate, sound can be important. Some animals use specialized vocalizations to turn the eye (and ear) of their beloved (including the túngara frog, whose call unfortunately also attracts predators), but what is one to do when you’re just a small glass frog living in a noisy waterfall? New research published in the journal Behaviour has discovered that these frogs have evolved to overcome their noisy surroundings by waving at each other to get attention.
The frogs observed practicing this behavior, which the researchers described as a “dance”, were found to combine their “love songs” with the flap of a hand, wave of a foot, or a bob of the head to bolster their chances of catching someone’s eye. Dancing frogs as a means of attracting a mate has been observed in wild populations in Borneo, Brazil, and India, but this latest sighting was near a waterfall in Ecuador.
