HALEAKALA — The Friends of Haleakala National Park will present a unique moonlight bird-watching program Sunday evening, April 17, at the summit of Haleakala.

The public is invited to “Experience Haleakala’s ‘Ua’u (Hawaiian petrels). See, hear and learn about these ghostly riders on the wind.”

The free program from 6:45 to 9:45 p.m. is limited to 60 participants. It will be hosted by Dr. Fern P. Duvall, state wildlife biologist.

Meet by 6:30 p.m. at the Haleakala Crater Overlook Visitors’ Center parking lot in time to outfit all flashlights or headlamps with red film coverings, to be provided, since normal white light may disturb the seabirds’ behaviors. Attendees are urged to dress warmly for the 10,000-foot elevation and to carpool due to limited space.

Entrance to the park is free for this event. Call Mele Stokesberry at 878-8015.
