Whiskered Wren
Pheugopedius mystacalis
Fairly large wren, found in foothills and subtropics from Venezuela to western Ecuador. More often heard than seen; listen for rich whistled song usually given in widely spaced repeated phrases. Rufous above and pale grayish below, with striped black-and-white face pattern. Black bars on tail, unlike similar Plain-tailed Wren, which is found at higher elevations. Sexes similar. Skulks in thickets and tangles at the forest edge, usually in pairs.
识别特征
The whiskered wren is 16 cm (6.3 in) long; a specimen from Venezuela weighed 29 g (1.0 oz). The nominate adult has a grayish-black crown, olivaceous gray nape, bright chestnut shoulders, back, and rump, and a reddish brown tail with dull black bars. It has a grayish white supercilium, a black line through the eye, blackish cheeks with a white line below and a black malar stripe below that. The chin and throat are off-white, the chest gray darkening to olivaceous gray on the belly, and the flanks reddish gray. The juvenile is duller than the adult with less prominent facial markings and a buffy throat.<p>The other subspecies have small differences from the nominate. P. m. saltuensis has a grayer chest and less distinct bars on the tail. P. m. yanachae has a slate-gray crown. P. m. macrurus' tail is dingy brown. P. m. amaurogaster is much darker with a sooty brown crown and ochraceous tawny underparts. P. m. consobrinus has a buffy tinge to the supercilium and a buffy neck and chest. P. m. tachirensis is darker than consobrinus with a dusky olive crown and white throat. P. m. ruficaudatus has more buff on its face and no bars on the tail.

分布与栖息地
The subspecies of the whiskered wren are found thus:<p>The whiskered wren inhabits dense undergrowth such as is found at the edge of humid forest and in regrowing clearings. It shuns the forest interior. In elevation it generally ranges between 1,200 and 2,400 m (3,900 and 7,900 ft) but can be found as high as 2,800 m (9,200 ft) and in Ecuador almost down to sea level.

行为
The whiskered wren forages in pairs as high as 10 to 12 m (33 to 39 ft) above ground. Its diet has not been described.<p>The whiskered wren appears to have a long breeding season; nest building has been observed from December to May. The nest is a large ball of roots and grass with a side entrance, usually placed in the fork of a small tree or in ferns.<p>Both sexes of whiskered wren sing in duet, "a splendid series of loud gurgling whistles" [1]. The call is "a deep throaty 'bong bong'" [2].

Nihoa Finch
Telespiza ultima
A finch-billed Hawaiian honeycreeper endemic to the island of Nihoa; does not occur on the main Hawaiian Islands. Unlikely to be confused with any other species; the only other passerine bird on Nihoa is the Millerbird, which lacks the Nihoa Finch’s heavy bill. Males have a bright yellow head and breast. Females are paler yellow and heavily streaked on the back. Common throughout the island.
Wallace's Hawk-Eagle
Nisaetus nanus
Typical small hawk-eagle. Small upright crest visible when perched. Adult has dark brown wings and a paler face. In flight, look for densely black-barred underparts, two white bands across the tail, and light brown on the inner part of the underwing (compared with the completely black-and-white underwings of Blyth’s Hawk-Eagle). Visibly smaller than both Blyth’s and Mountain hawk-eagles. Juvenile Wallace’s is pale tawny-brown on the head and on the underparts; the similar Blyth’s Hawk-Eagle has tail barring. Jerdon’s Baza can appear similar, but it has horizontal banding across the breast, whereas juvenile Wallace’s has unmarked underparts, pantaloons (fully feathered legs), and a broader black tip to the tail. Wallace’s Hawk-Eagle is often seen in flight over or perched on a snag in lowland forests and forest edges.
Juan Fernandez Tit-Tyrant
Anairetes fernandezianus
Restricted to Isla Robinson Crusoe in the Juan Fernandez Islands where no similar species occur. Uncommon and declining. Favors remaining patches of native scrub and low woodland, mainly at elevations above the town. Usually in pairs, hopping low in vegetation; can be curious. Identified by streaked breast and staring pale eyes; wispy crest is often held flattened.
