Whiskered Auklet
Aethia pygmaea
Small, blackish, eccentric-looking alcid. Breeds on remote volcanic islands in far northeastern Russia and the western Aleutians of Alaska; winters in the surrounding ocean. Breeding adult has a bright orange bill, fine white whiskers on the face, and a wispy black tuft that droops forward. Non-breeding adults have a short black tuft and much-reduced white whiskers. Crested Auklet is larger, with a stouter bill and a much smaller or completely lacking crest.
识别特征
An odd characteristic of this bird, which is also shared with the crested auklet, is that its plumage smells of citrus.<p>Fishing boats pose a huge threat to this bird, since it is attracted to lights at night.
分类信息
The whiskered auklet was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other auks in the genus Alca and coined the binomial name Alca pygmaea. Gmelin based his description on the "flat-billed auk" that had been described by the English ornithologist John Latham in 1785 and the "pygmy auk" that had been described by Welsh naturalist Thomas Pennant in the same year. Both authors had given the locality as Bird Island (now St Matthew Island) in the Bering Sea. The whiskered auklet is now one of four small auks placed in the genus Aethia that was introduced by the German naturalist Blasius Merrem in 1788. The genus name Aethia is from the Ancient Greek aithuia, an unidentified seabird mentioned by Aristotle. The specific epithet pygmaea is from Latin pygmaeus meaning "dwarf" or "pygmy". The species is monotypic: no subspecies are recognised.

White Eared-Pheasant
Crossoptilon crossoptilon
A large, ground-dwelling pheasant of high-elevation forests and scrub. It occurs near the treeline in coniferous and mixed woodland, typically at elevations of 3,000–4,300 metres.
Common Pauraque
Nyctidromus albicollis
Cryptically patterned nightbird; widespread and common in Central and South America, limited U.S. range. Found in shrubby woodlands. Patterned with gray, gold, and brown; note especially cinnamon cheeks and golden edges on back and wing feathers. In flight, note white outer tail feathers and white bar across the wings. Roosts on the ground during the day; actively hunts for insects at night. Song is a distinctive, rich, slightly buzzy "pur-WEEooo." Relatively long tail compared with other similar nightbirds.
Mascarene Paradise-Flycatcher
Terpsiphone bourbonnensis
A pretty and distinctive bird that always lacks the long tail streamers possessed by some paradise-flycatchers. Note the rufous back and tail and the gray underparts. Males and females differ slightly: males have a black cap and a blue eye-ring, whereas females have a dark-gray cap without a distinctive eye-ring. Fairly common on Reunion in all types of humid forest. Rare on Mauritius in remnant rainforest patches. Calls include a tearing “sree-sreeet” and an agitated twittering. The song is a long musical series of “twee” notes.
