The Center for Biological Diversity’s free wildlife ringtones are so popular that they are adding 17 new species from Hawaii. 

Listen to the monk seal ringtone below. It sounds a little cranky. 

 

The call of the wild is being heard more often now than ever. The Center for Biological Diversity’s free ringtones, featuring wildlife from around the world have been downloaded more than a half-million times, bringing the incredible growls, groans, hoots, chirps and trills of more than 100 species to cell phones across the planet.

“Whether it’s the howl of a Mexican gray wolf, the song of a beluga whale or the roar of a polar bear, these ringtones instantly connect people with wildlife, including species living at the edge of extinction,” Peter Galvin, the Center’s conservation director.

Calls from 113 species are available to download, including the jaguar, Pacific walrus, American pika, Florida panther, alligator, Gila monster, orca and more than 40 types of rare and endangered owls and birds. The calls have been downloaded about 515,000 times.

To celebrate the milestone, the Center just added 17 new species from Hawaii, including the scarlet honeycreeper, Hawaiian monk seal and Hawaiian hawk.
