White-browed Tit-Spinetail
Leptasthenura xenothorax
Small, active bird found locally in the southern Peruvian Andes. Brownish gray with a red cap, a white-streaked face, breast, and back, and a white eyebrow. Note its tiny, thumbtack-like bill and its fairly long, pointed tail. Forages in and near Polylepis patches, where it makes quick, short hops through dense bushy vegetation. Its song is a dry, rapid descending trill of chips.
识别特征
The white-browed tit-spinetail is 16 to 18 cm (6.3 to 7.1 in) long and weighs about 13 g (0.46 oz). It is a small-bodied, long-tailed furnariid with a short bill. The sexes have the same plumage. Adults have a white supercilium with a narrow black border above it on an otherwise blackish and whitish streaked face. Their crown is bright rufous. Their upperparts are dull grayish brown, with narrow black-outlined white streaks that become more prominent on the lower back, then fainter on the rump, and become more obvious but still pale on the uppertail coverts. Their wings are dark fuscous with dull rufescent edges on the coverts and a pale tawny patch across the flight feathers. Their tail is mostly dark fuscous to black; the feathers have bare shafts on their tips giving a spiny appearance. Their throat and upper breast are whitish with coarse black mottling and the rest of their underparts are unmarked pale gray-brown. Their iris is brown to blackish gray, their bill black with a pinkish base to the mandible, and their legs and feet black.

分布与栖息地
The white-browed tit-spinetail is found only in the Peruvian Andes. It is only known from a few locations in the departments of Cuzco and Apurímac. It primarily inhabits Polylepis woodlands but occasionally occurs in montane scrublands. It favors large areas of primary forest but will forage in smaller patches. In elevation it occurs between 3,700 and 4,550 m (12,100 and 14,900 ft) but is most common in the lower part of that range.

Akekee
Loxops caeruleirostris
A small, very rare Hawaiian honeycreeper of remote native forests on Kauai. Declining rapidly; found only above 4,000 feet elevation in the eastern ‘Alaka’i Plateau. Males are yellow with a small black mask and females are greenish. The crossed bill that is uses to pry open leaf buds in search of insects and larvae is difficult to see. The longer tail with a notched tip distinguishes it from other small honeycreepers. Its rarely-heard song is a wavering trill that changes in speed and pitch. Call is a soft upslurred “suweet.”
Angola Batis
Batis minulla
A cute and striking gray, white, and black flycatcher-like bird with a yellow eye, white wingbars, and a white spot above the bill base. Sexes differ: male’s chest band is black and female’s is chestnut. Pairs hunt for insects, sometimes joining flocks, in woodland, dry forest, and dense thickets. Calls include a series of 15–20 clear high-pitched “seeet” notes that slowly descend, and a typical batis churring and croaking. Male Angola Batis looks almost identical to male Chinspot Batis, but the latter prefers drier savanna habitat and calls differently; female Chinspot has a distinctive brown spot on the chin; the larger Black-headed Batis has a complete eyebrow.
White-throated Towhee
Melozone albicollis
Large, rather plain brownish sparrow endemic to dry interior foothills and highlands, mainly in Oaxaca. Generally quite common and conspicuous. Found in brushy woodlands, gardens, and farmland with hedges; often in pairs or small social groups. Feeds mainly on the ground, but also at low to middle levels in bushes and brush. Subtly attractive if seen well, with a white bib, rusty throat band, and rusty vent.
