Wearing headlamps and muck boots, the band of volunteer conservationists trudges into dark forests in Hawaii Volcanoes National Park and surrounding communities, turning over leaves and shining lights on tree trunks. Their quarry is a tiny frog called the coqui. No bigger than a quarter, the coqui makes an ear-splitting call as loud as a lawn mower: Ko-kee! Ko-kee! It takes special know-how and fortitude to home in on a frog in a blackened forest ringing with frog calls.
