Ochre-browed Thistletail
Asthenes coryi
Tiny bird with a long, spiky red tail, a vocal and active resident of grass and bushes above treeline. Dull brown upperparts, grayish brown underparts, and a distinctive orange face and chin. Sexes similar. Not common and difficult to approach closely; often alone or in pairs foraging in paramo bushes or treeline borders. Song is an ascending series of high-pitched whistles “fuuuuuEE-peep-PEEP-PEE’REE!” Call is a soft, querulous “peew.” The only unstreaked Furnariid in the Venezuelan paramo. Endemic to the Andes of Venezuela.
识别特征
The ochre-browed thistletail is 16 to 18 cm (6.3 to 7.1 in) long and weighs 15 to 18 g (0.53 to 0.63 oz). The sexes have the same plumage. Adults have an ochraceous supercilium on an otherwise darker face. Their forehead is dull ochraceous rufous, and their crown, back, rump, and tail are olive-brown. Their wings are a dull reddish brown. Their tail is long and deeply forked with few barbs at the feather ends that give a ragged appearance. Their chin has a tawny-rufous patch. Their throat and the rest of their underparts are pale gray-brown with a whitish center to the belly. Their iris is dark brown to gray-brown, their bill dark grayish brown with a pinkish base to the mandible, and their legs and feet bluish gray.
分类信息
The ochre-browed thistletail was long treated as a subspecies of the white-chinned thistletail (then Schizoeaca fuliginosa, now Asthenes fuliginosa) but was eventually separated as a species. They and several other species were in genus Schizoeaca but genetic data showed that the genus is embedded within Asthenes. The ochre-browed thistletail is monotypic.

分布与栖息地
The ochre-browed thistletail is found in the Andes of western Venezuela between the states of Trujillo and Táchira. It primarily inhabits páramo grasslands, taller páramo vegetation, the upper edge of cloudforest, and dense undergrowth at tree line. In elevation it mostly ranges between 3,500 and 4,100 m (11,500 and 13,500 ft) though it occurs in openings in cloudforest as low as 2,800 m (9,200 ft).

Blue Cotinga
Cotinga nattererii
Striking cotinga found from eastern Panama to northwest Ecuador. Male is deep sky blue with a dark purple throat and belly and mostly black wings. Female is much different: brown with scaly pattern above and spots below. Note large eye with pale eyering, short bill, and typical plump cotinga shape with short square tail. Typically found in the canopy of lowland forest, often perched conspicuously. Sometimes gathers at fruiting trees. Occasionally ventures into the foothills, up to around 1,400 m.
Sandhill Grasswren
Amytornis oweni
Small, long-tailed bird with black mustache and rufous-brown upperparts, found in the deserts of eastern Western Australia and central Australia, where it scampers between large spinifex clumps in sand dune habitat. Usually seen only with a dedicated search. Upperparts rufous-brown, with white throat and pale underparts. Formerly considered conspecific with Pilbara Grasswren, and together treated as “Rufous Grasswren”; also formerly lumped with Striated Grasswren.
Streak-breasted Honeyeater
Meliphaga reticulata
A fairly small honeyeater of lowland and foothill wooded areas on Timor. Olive-gray upperparts with greenish wing feathers, pale underparts with thick, dark streaks, sometimes looking like white streaks on a dark background. Yellow-orange ear patch, white throat and moustache stripe. Similar to Yellow-eared Honeyeater, but Streak-breasted Honeyeater lacks the yellow underparts. Voice, various whistles, rasps and mechanical warbles.
