Ringed Storm-Petrel
Hydrobates hornbyi
Handsome small seabird of Humboldt Current; not seen from shore, but breeds inland in Atacama Desert where it visits colonies at night to avoid predators. Plumage unlike all other storm-petrels, with black cap and collar, and white underparts contrasting with dark underwings. Upperparts also striking, with black cap, strong upperwing pattern, and gray tail (no contrasting white rump). Larger than most storm-petrels in its range, but size similar to Markham’s and Black Storm-Petrels, with which it readily associates.
分类信息
The ringed storm petrel was formally described in 1854 by the English zoologist George Gray and given the binomial name Thalassidroma hornbyi. He chose the specific epithet to honour Admiral Sir Phipps Hornby who had obtained the specimen. The ringed storm petrel was formerly placed in the genus Oceanodroma but is now placed in the genus Hydrobates, the only genus in the Northern storm petrel family Hydrobatidae.

保护状况
It is difficult to know how threatened, if at all, the ringed storm petrel is. At sea, estimates put the population in the thousands or tens of thousands. Recently a vagrant ringed storm petrel was seen off the coast of California by a team from the NOAA.

Wied's Tyrant-Manakin
Neopelma aurifrons
Nondescript manakin that may be mistaken for a flycatcher. Has an olive-green back, a grayish throat, and yellowish underparts. The yellow crown patch is typically concealed. Found in the interior of humid forests, occasionally venturing to the edges. A common call is a startled “yo-dee-wo-dee”. The similar Serra do Mar Tyrant-Manakin has a conspicuous yellow crown patch, occupies different edge habitats, and has a more complex song.
Rufous-headed Pygmy-Tyrant
Pseudotriccus ruficeps
Tiny, plump flycatcher found in the understory of subtropical and temperate cloud forest in the Andes. Not likely to be confused. Bright rufous head, wings, and tail contrast with olive back and breast. Belly slightly paler yellow. Sexes similar. Flits around the understory in singles or pairs, usually within forest. Best detected by its bill snaps or descending rattle call.
Steller's Sea-Eagle
Haliaeetus pelagicus
An immense eagle with large head and massive orange bill to match. Adult is striking, even from a great distance: rich brown overall, with snow-white tail, belly, and shoulder patches. Juvenile and immatures darker but usually acquire mostly white, wedge-shaped tail in second year. Younger birds can be confused with young White-tailed Eagle, but Steller’s distinguished by larger bill, wedge-shaped tail, and unique wing shape, narrow at the tip, bulging in the middle, then narrowing near the body. Plucks fish from icy seas and follows fishing boats for scraps. Often associates with White-tailed Eagles where prey is abundant.
