For forest birds, visit Kokeʻe State Park, where you can find ʻElepaio, ʻAmakihi, ʻAnianiau, ʻApapane, Kauaʻi ʻAkepa and possible ʻIʻiwi and Kauaʻi Creeper. The nearby Alakaʻi Swamp has many of the same birds, with many more ʻIʻiwi, a better chance of seeing the Kauaʻi Creeper, and the remote possibility of seeing the Puaiohi. Try the Pihea Trail.
On the way up to the park, Waimea Canyon features many White-tailed Tropicbirds, and watch for Pueo as well in the surrounding dryland areas.
Wailua River Valley on Kuamoʻo Road (Route 580, about 6 miles north of Lihuʻe) is a beautiful place to look for Koloa, ʻAlae ʻUla (Common Moorhen) and the Japanese Bush-warbler. The two Laughing Thrushes and the Western Meadowlark may also be found there. Follow the road to Kuahua Arboretum and enjoy the birding along the way.
For seabirds, Kilauea National Wildlife Refuge is a must. Expect to see Tropicbirds, Frigatebirds, Boobies, Shearwaters and Albatross in season.
All four endemic waterbirds can be seen at Hanalei National Wildlife Refuge on the north shore up the road from Kilauea NWR.
