Palau Nightjar

Big, spectacular, black-and-white hornbill. The males have a large black-and-white bill, and females a much smaller all-dark one. In flight, shows a broad white patch at the back of the wing and a black tail with white sides. Found in thick forest and adjacent areas of lush woodland and cultivation. Usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to White-thighed and Brown-cheeked Hornbills, but has a black center to the tail, and the wingtips are black. Also has a darker bill and casque than those species.

A very small seabird of southern oceans. Gray-black on head, neck, throat, and top of breast. Back and upperwing are paler in color and rump is ash-gray. Note the white belly and white underwing with a black edge. Shows relatively short black legs and square tail. Forages in deep waters of the subantarctic; in the New Zealand region, rarely seen near the mainland. Differs from other black-and-white storm-petrels by its gray rather than white rump. White-faced Storm-Petrel also has a gray rump but is larger with longer legs, white on the face, and a more bounding flight.

Small oceanic gull with stunning wing pattern. All ages show distinctive black outer wing, white inner wing, and dark back. Breeding adults have a dark gray head and black bill with yellow tip. Nonbreeding adults have similar distinctive bill but with a mostly white face. Young birds are browner above than adults, with a crisp scaly pattern on the back. Breeds on Arctic tundra. Often seen in flocks during migration and winter, generally far offshore. Rarely seen from shore, but occasionally shows up at large inland bodies of water.
