Montane Woodcreeper
Lepidocolaptes lacrymiger
Fairly small and slender woodcreeper found in Andean subtropical zone from Venezuela to Bolivia. Warm brown overall, with rufous wings and tail. Distinct white streaking on underparts, white throat, and white eyebrow. Note slender, obviously decurved bill, which is useful to separate Montane from other woodcreepers in range. Fairly common in mossy cloud forest, where it frequently follows mixed species flocks. Like other woodcreepers, hitches up tree trunks and large limbs.
识别特征
The montane woodcreeper is 19 to 19.5 cm (7.5 to 7.7 in) long; males weigh 31 to 35 g (1.1 to 1.2 oz) and females 29.5 to 33 g (1.0 to 1.2 oz). It is a smallish to medium-sized woodcreeper with a slim, slightly decurved bill. The sexes have the same plumage. Adults of the nominate subspecies L. l. lacrymiger have a markedly streaked face and neck with a whitish supercilium that is often broken. Their crown and nape are dusky brown with conspicuous whitish buff spots with black tips; the spots become streaks on the nape. Their back and wing coverts are rufous-brown and their rump, wings, and tail rufous-chestnut. Their underparts are olive-brown with long, wide, black-edged and tipped buffy streaks . Their iris is dark brown and their legs and feet olive-gray to dark horn. Their maxilla is blackish to dusky gray or dark horn and the mandible pale gray to whitish. Juveniles have less distinct borders on the underside streaks, and a shorter and darker bill.<p>The other subspecies of the montane woodcreeper differ from the nominate and each other thus:
分类信息
The montane woodcreeper was formerly considered conspecific with the spot-crowned woodcreeper (L. affinis) but they were split in the early 2000s.<p>The montane woodcreeper has these nine subspecies:

分布与栖息地
The subspecies of the montane woodcreeper are found thus:<p>The population of the montane woodcreeper on the western slope of the Andes in northwestern Peru could be either L. l. aequatorialis or L. l. warscewiczi.<p>The montane woodcreeper inhabits a variety of forested landscapes, mostly in mid- to upper elevations. It favors montane evergreen forest and cloudforest, and also occurs in somewhat open woodland, montane deciduous forest, and stunted forest near treeline. It is found in the interior of primary forest but is thought to be more common at its edges and in mature secondary forest. It also occurs in clearings and pastures with trees. In elevation it generally ranges between 1,750 and 3,000 m (5,700 and 9,800 ft) but is occasionally found as low as 900 m (3,000 ft) in Venezuela. In Colombia it ranges between 1,700 and 3,500 m (5,600 and 11,500 ft) and in Ecuador between 1,500 and 3,000 m (4,900 and 9,800 ft).

行为
The montane woodcreeper is a year-round resident in most of its range; in Venezuela there is some movement to lower elevations in the rainy season.<p>The montane woodcreeper's diet is not known in detail but is primarily arthropods. It typically forages singly or in pairs and regularly joins mixed-species feeding flocks. It is not known to follow army ant swarms. It hitches up trunks and along the underside of branches, typically from the forest's midlevel to the subcanopy and seldom near the ground. It captures prey by gleaning from surfaces and by probing bark crevices, epiphytes, and moss.<p>The montane woodcreeper's breeding seasons vary geographically but generally fall within April to August. It nests in a cavity in a tree or stump, either natural or excavated by a woodpecker. One nest contained three eggs. The incubation period and time to fledging are not known. Pairs are thought to remain together year-round, and both sexes are assumed to care for young.<p>The montane woodcreeper is not highly vocal. Its song is "a 2·5 second series of 10–15 high-pitched whistles that accelerates and descends: 'tsip, tsip, tsip, ts-ts-tseeeéu, tseeu, tseu-tseu-tseu-tseu' or 'tseu, tseu, tsip-tsip, tsee-tsee-tsee-tsee-tsee' ". It also makes a "series of 3 reedy squeaks", a "double-noted cry", and a "rattle with introductory 'ah' ".

Blue Crane
Anthropoides paradiseus
A small, elegant, uniformly blue-gray crane that dwells in open habitats in pairs and variably sized groups. The bulbous head, plain face lacking any naked skin, and lack of contrast in the wings are distinctive. It is a resident and partial nomad in semi-desert, grassland, and cereal cropland. A staccato, bugling “kkk-kk-kk-kk-krraaak” call often first gives them away.
Least Bittern
Botaurus exilis
This diminutive heron is fairly common in its preferred wetland habitat, but secretive and easily overlooked. Tiny size and attractive pattern of orange, black, and white is distinctive among herons within its range. Males are blacker above; females are browner. Occurs throughout much of North and South America, where it can be found in marshes with a mix of open water and vegetation, often with cattails, phragmites, or lily pads. Usually seen perched motionlessly, straddling reeds at the edge of water. Occasionally makes short flights just above the reeds. Listen for the soft cooing song, given during the day and at night.
Stripe-breasted Rhabdornis
Rhabdornis inornatus
A medium-sized bird of foothill and lower montane forest with a white throat and belly, brown upperparts, darker wings and tail, a black mask, a gray crown, and pale brown sides broadly streaked white. Often perches on dead branches. Similar to Stripe-sided Rhabdornis, but usually found at higher elevations, and has a shorter, thicker bill and a crown that is gray rather than streaked white. Voice includes high-pitched chips, sometimes given in rapid series.
