Equatorial Graytail
Xenerpestes singularis
Streaky, warbler-like bird found in cloud forest along the east slope of the Andes in Ecuador and northern Peru. It has a gray back and wings, white underparts streaked with gray, and white eyebrows. Forehead is chestnut, but this can be very hard to see in the field. In foggy conditions, barred tail helps separate it from Gray-mantled Wren. Typically found in pairs that forage high in the canopy, and often joins mixed-species flocks. Song is a very long, gravelly chatter.
识别特征
The equatorial greytail is about 11.5 cm (4.5 in) long and weighs about 12 g (0.42 oz). It is a tiny furnariid that resembles a warbler. The sexes have the same plumage. Adults have buff and grayish grizzled lores and a thin buffy white supercilium on an otherwise grayish face. Their forecrown is rufous with black streaks and their rear crown, back, rump, and tail are olive-gray. Their wings are dusky with gray-brown coverts and thin medium brown edges to the flight feathers. Their underparts are creamy white with blurry gray streaks. Their iris is gray-brown, their maxilla slate gray to black, their mandible creamy to pale gray, and their legs and feet olive-brown. Juveniles differ from adults by having gray bars rather than streaks on their underparts.
分类信息
The equatorial greytail is monotypic. It shares genus Xenerpestes with the double-banded greytail (X. minlosi) and together they are sister species to the orange-fronted plushcrown (Metopothrix aurantiaca).

分布与栖息地
The equatorial greytail is found in the foothills of the east side of the Andes from Ecuador's Napo Province south slightly into northern Peru. It inhabits the interior and edges of humid montane forest. In elevation it ranges from 1,000 to 1,600 m (3,300 to 5,200 ft) in Ecuador and 1,050 to 1,700 m (3,400 to 5,600 ft) in Peru.

Bar-breasted Piculet
Picumnus aurifrons
Small, greenish-brown piculet. Light olive brown, with horizontal barring on the breast changing to vertical streaking on the belly, and a black-and-white speckled crown. Males have a yellow forehead patch. Forages singly or in pairs around the midstory and canopy of secondary rainforest, sometimes joining mixed-species flocks with tanagers and other species. Its song is a high, two- or three-note “sweet, sweet,” similar to the songs of other piculets.
Common Firecrest
Regulus ignicapilla
Tiny bird, smaller than a warbler, with distinctive combination of boldly striped head, white wingbars, and bronzy-golden patch on sides of neck. Male has a fiery orange crown stripe; female's is yellow. Inhabits mixed forests, plantations, and gardens, usually in areas with conifers. In autumn and winter, often travels with foraging flocks of tits and other small woodland birds. Inconspicuous but active, often high in the canopy, giving high, thin, lisping vocalizations.
Rufous-necked Foliage-gleaner
Syndactyla ruficollis
Relatively brightly-colored foliage-gleaner restricted to mountains and hills of southwestern Ecuador and northwestern Peru. It has an orange nape and sides of neck, a cinnamon tail, buffy eyebrow and throat, and buffy streaks on the underparts. Sexes look alike. Found in both dry and humid forest, including areas with abundant bamboo, and typically seen at lower to middle levels. Song is a harsh, scratchy “bouncing ball” series. Threatened by habitat loss.
