Plain White-eye
Zosterops hypolais
This small warbler-like bird is unremarkable in appearance, but surely not the plainest of the white-eyes; look for a pale eye with a very narrow white eyering, grayish upperparts, and contrasting pale yellow throat. Endemic to the island of Yap, in the Western Caroline Islands of Micronesia, where it inhabits a wide range of forested and brushy habitats. The only other white-eye on the island, Yap White-eye, is dark olive-brown overall and has a much more prominent eyering. Forages actively in flocks. Gives high-pitched, scratchy trills and chirrups, comparable to parakeet and sparrow calls.

Ultramarine Lorikeet
Vini ultramarina
A mostly blue-and-white lorikeet with a bright ultramarine upperside and darker blue thighs, chest band, and crown. Chest, throat, cheek, and belly are white with dark flecking. Unique within its range. Common call is a high-pitched buzzing “tzeet.”

Christmas Shearwater
Puffinus nativitatis
A medium-sized shearwater with uniformly dark brown plumage and no contrasting markings. Flies more steadily than most shearwaters and usually flies low over the water. Large numbers nest on most of the Northwestern Hawaiian Islands. A few pairs nest on Moku Manu Islet off the eastern coast of Oahu. Often seen from boats in the Northwestern Hawaiian Islands, but rarely on the main islands and rarely from shore. The voice, usually heard only at breeding colonies, is a low moan.

Black-throated Antbird
Myrmophylax atrothorax
Medium-sized antbird of dense understory and riverside vegetation. Males are deep chestnut-brown, with black throat and white wing spots; females are lighter red-brown above, light tan below, with white wing spots as in male. Typically found in dense vegetation along rivers, particularly common in dense cane stands; sometimes also found away from water around forest edges and in tree fall gaps. Listen for an ascending series of high, whiny notes, decelerating then accelerating.
