Many of Hawaii's tropical birds are found nowhere else on earth. There are curved-bill honeycreepers, black-winged red birds, and the rare o'o, whose yellow feathers Hawaiians once plucked to make royal capes. When you go birding, take along A Field Guide to the Birds of Hawaii and the Tropical Pacific, by H. Douglas Pratt, Phillip L. Bruner, and Delwyn G. Berett (Princeton University Press, 1987).

Kauai and Molokai, in particular, are great places to go birding. On Kauai, large colonies of seabirds nest at Kilauea National Wildlife Refuge and along the Na Pali Coast. Be sure to take along a copy of The Birds of Kauai, by Jim Denny (University of Hawaii Press). The lush rainforest of Molokai's Kamakou Preserve is home to the Molokai thrush and Molokai creeper, which live only on this 30-mile-long island.
