A White-tailed Tropicbird (Phaethon lepturus dorotheae; "Koa‘e kea" in Hawaiian) soars along the steep-walled canyon feeding into the bay adjacent to Kilauea Point, north Kaua'i. Adult birds have mostly white plumage with long, white tail streamers (33-40 cm). Tail feathers are visible while the bird is in flight as compared to the koa‘e ‘ula. Black eye-stripe from gape curving toward and passing through eye. Diagonal black stripe across upper wings. Yellowish to orange bill. Legs/feet are yellowish with black webs. Length: 38-40 cm (15-16 in), 71-81 cm (28-32 in) including tail streamers; wingspan: 89-94 cm (35-38 in); average life span: 16 years. Typically solitary feeders though sometimes seen in pairs. With folded wings, koa‘e kea hit the water and completely submerge to seize and swallow prey before flight. Prey consists of fish and squid.
