HANAWI, Maui — Sitting in the mud on a forest bed of ferns, Hanna Mounce searches for a new track on her old MP3 player.

She squints through spitting rain at the mystical ohia trees, adorned with lovers-red lehua blossoms. They dominate the landscape up here on the north slope of Haleakala, the 10,000-foot shield volcano in East Maui.

Mounce taps a button and a bluetooth speaker nestled in rotting, moss-covered branches begins to chirp 10 yards away. She skips to the next track, sporadic cheeps.

It’s a recording of a Maui parrotbill, or kiwikiu in Hawaiian, now among the world’s most endangered birds. She hopes to lure one into a nearly invisible 30-foot net strung up between two fishing poles that are staked into the ground with PVC pipes.
