Oaxaca Sparrow

Large wren usually found in small groups, less often in pairs. Mainly found in thorn forest and dry scrubby habitats. Note boldly barred wings and tail and russet nape patch. At most only limited overlap with the formerly conspecific Rufous-backed Wren; in Russet-backed the barring and spotting on the upperparts is more prevalent, and whatever rufous coloration is present is generally not as bright. Often detected by its marvelous loud song, often given by multiple birds at once, which consists of various nasal and whistled notes, with some harsh elements mixed in.

Long-winged, wedge-tailed, delicate seabird of far northern climates, nesting in open wet tundra and wintering around sea ice, occasionally moving into coastal areas. Breeding adult astonishingly beautiful: pearly gray above, rose-pink below, with coral-red legs, thin black collar, and tiny black bill. Nonbreeding adult has a tiny black dot near the ear and loses the black collar and much or all of the pink coloration. First-winter birds have blackish “M” pattern in upperwing and black tip on wedge-shaped tail. Flight graceful and buoyant.

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.
