Scissor-tailed Nightjar
Hydropsalis torquata
Boldly marked nightjar; streaked brown, gray, and buff above and barred brown below with a prominent rufous neck patch. Males have spectacular scissor-shaped tail extensions, dark on the outside, pale on the inside. Tail of females is short with no white. Fairly common in grasslands with scattered bushes and at forest edges.
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.
Red-shouldered Hawk
Buteo lineatus
Smaller than Red-tailed Hawk. Adults are beautiful with rich orange barring below and bold black-and-white checkerboard patterning on wings. Often in forested areas, where they hunt from perches. Perches on wires more frequently than Red-tailed Hawk. In flight, wings seem narrow and pushed forward compared to Red-tailed or Broad-winged Hawk; also note relatively long tail. Population in California is more richly colored (darker orange) than paler Eastern birds; while Florida birds are paler with gray head and back.
