Scalloped Woodcreeper
Lepidocolaptes falcinellus
Medium-sized woodcreeper with a short, slightly decurved pinkish bill. Found in humid and montane forests, including Araucaria forests, where it typically forages in the canopy. The rufous back contrasts with the whitish throat and prominent eyebrow. Note the buff streaking on the darker brown head and the scaled belly. Similar to Scaled Woodcreeper, which has a duller crown and a less rufous tail.
识别特征
The scalloped woodcreeper is 17 to 20 cm (6.7 to 7.9 in) long and weighs 26 to 30 g (0.92 to 1.1 oz). It is a medium-sized woodcreeper with a longish somewhat decurved bill. The sexes have the same plumage. Adults' faces are creamy white with blackish mottling and have creamy white lores and supercilium. Their crown and nape are dusky to dull black with obvious rich buff spots that often continue as faint streaks onto the upper back. Their back and wing coverts are olive-brown to cinnamon-brown, and their rump and tail rufous-chestnut. Their flight feathers have brown outer webs, chestnut inner webs, and blackish brown tips. Their throat is whitish. Their underparts are olive with bold, blackish-edged, buff streaks that give a scaly appearance. Their underwing coverts are cinnamon. Their iris is brown and their legs and feet greenish gray to greenish brown. Their bill's maxilla is gray, light brown, or pinkish, often with a darker base, and their mandible is creamy white to light brown.

The scalloped woodcreeper and what is now the scaled woodcreeper (L. squamatus) were previously considered conspecific and are now treated as sister species. The scalloped woodcreeper is monotypic.

分布与栖息地
The scalloped woodcreeper is found from northeastern São Paulo state in southern Brazil south to Alto Paraná Department in southeastern Paraguay, Misiones and Corrientes provinces in northeastern Argentina, and extreme northeastern Uruguay. It inhabits humid Atlantic Forest and drier forest in the planalto. In the northern part of its range it occurs in montane evergreen forest and rainforest, further south in Araucaria forest, and infrequently in semi-deciduous forest in the southwest. It occurs at the edges and interior of primary forest and older secondary forest. In elevation it mostly ranges from the lowlands to 1,600 m (5,200 ft) and only rarely is found up to 2,000 m (6,600 ft).

行为
The scalloped woodcreeper is believed to be a year-round resident throughout its range.<p>The scalloped woodcreeper's diet is not known in detail but appears to be mostly arthropods. It usually forages singly or in pairs, and often joins mixed-species feeding flocks. It hitches up trunks and along branches, mostly from the forest's mid-level to the canopy but sometimes in the understory. It takes most of its prey from epiphytes, bromeliads, moss, and bark surfaces and crevices. It has been observed making sallies to catch prey in mid-air.<p>The scalloped woodcreeper's breeding season has not been defined but appears to span at least October to December. It nests in cavities in trees that it lines with bark flakes. One nest held two eggs. The incubation period is 15 to 16 days and fledging occurs 18 to 19 days after hatch. Both parents brood and provision nestlings.<p>The scalloped woodcreeper's song has not been put into words. Its call is "a somewhat slurred rattle, described as 'pit, eu-u-u', 'pee-u-u-u' or 'peekku' ".

Gray-headed Piprites
Piprites griseiceps
Confusing forest species, rare and difficult to find among mixed flocks. Typically stays at middle levels. Overall dull olive with yellower underparts and proportionally large gray head. Most noteworthy are the stout bill and large eye with a thin whitish eyering.
Newton's Sunbird
Anabathmis newtonii
A small sunbird with dark olive upperparts. Male has an iridescent green-purple throat and upper breast; female has a dull scaly olive throat and yellowish underparts. Juvenile lacks yellow underneath. A common endemic resident in almost all habitats below 1800 meters across São Tomé. Pairs and small groups frequently join mixed-species flocks. Gives a typical rapid, rambling high-pitched sunbird song and a shrill “tseeet” call.
Gansu Leaf Warbler
Phylloscopus kansuensis
Small, confusing leaf warbler with olive-yellow upperparts, yellow brow, double wing bars, and a pale crown stripe. Extremely similar to many other small leaf warblers: Pallas’s Leaf Warbler has a brighter yellow brow stripe, and Chinese Leaf Warbler has an incrementally weaker head pattern and a small hook at the rear end of the black eye stripe. Lemon-rumped Warbler is extremely similar visually but averages paler on the brow stripe and darker on the underparts. Listen for the song, an accelerating series of sharp chips followed by a trill; its calls include a tinkling series of chips. Inhabits mid-altitude forests, usually bushy poplar and birch groves; found at lower altitudes than Chinese Leaf Warbler.
