White-striped Woodcreeper
Lepidocolaptes leucogaster
Attractive and fairly active, medium-sized woodcreeper of pine and pine-oak woodland in highlands. Usually found in ones or twos, often traveling with mixed-species feeding flocks of tanagers, orioles, warblers, and others. Creeps up trunks and smaller branches, often poking into epiphytes. Note the slender, slightly curved bill and bold whitish striping on head and underparts. Song is a pleasant, chipping, descending trill, mainly given in early morning.
识别特征
The white-striped woodcreeper is 21.5 to 23.5 cm (8.5 to 9.3 in) long and weighs 30 to 40 g (1.1 to 1.4 oz). It is a slim, medium-sized woodcreeper with a long, slender, decurved bill. The sexes have the same plumage. Adults of the nominate subspecies have a mostly pale face that often has dusky streaks or smudges. They have white to buff-white ear coverts, supercilium, and eyering with a blackish or dusky stripe behind the eye. Their crown, nape, and sides of the neck are blackish to dark brown. Their forehead has buffy to whitish buff spots that become streaks on the crown and nape and usually extend onto the back. Their back and wing coverts are olive-brown or tawny. Their flight feathers, rump, and tail are cinnamon-rufous to rufous-chestnut. Their flight feathers have brownish bases and their primaries have dusky tips. Their throat and breast are white to creamy white; the throat is unmarked and the breast has a blackish scaly appearance. The rest of their underparts are dusky gray with white streaks that fade to the belly. Their underwing coverts are ochraceous buff. Their iris is brown, their maxilla dark brown or blackish, their mandible whitish gray to pinkish, and their legs and feet gray to blackish. Juveniles have more olive-brown upperparts than adults, their underparts' markings are less regular, and their bill is shorter. Subspecies L. l. umbrosus is smaller than the nominate, with whiter spots and streaks on the head and whiter underparts with blacker streaks.

分布与栖息地
The white-striped woodcreeper occurs only in Mexico. Subspecies L. l. umbrosus is found in northwestern Mexico from Sonora and Chihuahua south to Durango, Nayarit, and Jalisco. The nominate L. l. leucogaster is found in western and southern Mexico. On the Pacific side and interior it occurs from Jalisco and Zacatecas south to Oaxaca, and on the Caribbean side from Veracruz south to Oaxaca. The species mostly inhabits humid montane forest and drier oak, pine-oak, and pine-fir forest in the subtropical and temperate zones. It also occurs in lowland tropical deciduous forest and, at higher elevations, mixed coniferous forest. It favors mature forest but occasionally occurs in secondary forest. In elevation it mostly ranges from 900 to 3,500 m (3,000 to 11,500 ft) but has been recorded as low as 400 m (1,300 ft) and as high as 4,000 m (13,000 ft).

行为
The white-striped woodcreeper is essentially a year-round resident throughout its range, though some may move to lower elevations in winter.<p>The white-striped woodcreeper's diet is mostly arthropods. It typically forages singly or in pairs, and often joins mixed-species feeding flocks. It forages at all levels of the forest, hitching in a spiral up trunks and branches. It captures prey by flaking bark and probing into crevices.<p>The white-striped woodcreeper's breeding season has not been fully defined but includes at least February to May. It apparently nests in tree cavities. Nothing else is known about its breeding biology.<p>The white-striped woodcreeper's song is "a sputtering trill...'zzzzzzzzztztztztztzttt-t-t-bt-bt-bt'." Its call is "a short rough trill...'tsisirr'."

Usambara Greenbul
Phyllastrephus albigula
A very small, warbler-like greenbul with an olive-green back, pale underparts, an olive-washed gray cap and nape, and a yellow or orange eye. Found in montane forest at middle elevations. Often joins mixed-species flocks. Very similar in appearance to Tiny Greenbul, but found at higher elevations and darker overall, with an olive-green wash to the crown and nape. Similar in overall coloration to Yellow-streaked Greenbul, but much smaller, with a pale eye. Voice apparently very similar to Tiny Greenbul’s. The call is a rough chattering trill that is often mixed with the song: an accelerating, syncopated series of low nasal notes.
Green-and-white Hummingbird
Elliotomyia viridicauda
Medium-sized hummingbird of middle elevations. Green above, white below, with a variably pinkish lower mandible. Found in humid forest and around forest edges. Distinguished with care from the very similar White-bellied Hummingbird by its completely dark underside of the tail (where there is some white in White-bellied), and by its sometimes darker lower mandible. Green-and-white Hummingbird is also typically more closely associated with forested habitats than White-bellied.
Two-banded Warbler
Myiothlypis bivittata
Small, yellowish bird with a fine black bill and distinctive black stripes on head. Mostly green above and yellow below; has rufous or orange crown bordered by black, but crown color can be difficult to ascertain. Note olive eyebrow becoming yellow in front of eye, and bright pinkish-yellow legs. Inhabits dense understory of foothill forests along the eastern slope of the southern Andes and in the tepui region. Usually occurs in pairs or small family groups that forage actively for insects, often joining mixed-species flocks. Song in tepuis is a series of chips followed by a high-pitched, screeching note. In southern part of range, song is very different: a rich rollicking series of notes that may vaguely recall House Wren and is often given by pairs as a duet. In southern Andes, most similar to Golden-bellied Warbler but has olive (not entirely yellow) eyebrow; also similar to Golden-crowned Warbler but typically occurs at higher elevations and has olive (not whitish) eyebrow.
