The coqui is the national symbol of Puerto Rico. It's a tiny, but vociferous tree frog that lulls residents to sleep every night with the male's lusty "croak."
But they're not so welcome on the Big Island of Hawaii.
Coquis arrived there as stowaways a few years ago. Because the frog has no natural predator on the island, they've been proliferating like a 'plague of locusts', competing with native birds and animals for food, and leaving many angry Hawaiians sleepless in paradise.
Frog populations around the world are in sharp decline, so American radio producers Dan Collison and Elizabeth Meister went to ask residents why Hawaii's the only place in the world that is trying to kill as many frogs as possible.
