Join the Hawai‘i Audubon Society on a field trip along Pu‘u ‘O‘o Trali with Les Chibana. You will bird along this trail that crosses a few old lava flows from Mauna Loa checking several kipuka for native forest bird activity. The trail is fairly level with a few short grades. The footing can be uneven with some loose, gravel-sized rocks. This is not a walk for those who are unsure of their balance. If we can carpool, we might make a short extension to the area outside Kipuka 21, which is currently closed for trail work. Bring snacks and plenty of water. Sturdy walking shoes and hiking sticks are recommended. Bring sun protection and be prepared for some rainfall. Steady or heavy rain cancels. Meet at the Pu‘u ‘O‘o parking area at 9:30 a.m. The parking area is near the 23 mile marker on the south side of Saddle Road. The realignment work has made this area a little more obscure. Watch for the small signs and graded ‘a’a parking area just off the road. Call Joan Carroll at (808) 883-9845 or Noreen Chun at (808) 883-2118.
