Gray Wren
Cantorchilus griseus
Small, short-tailed, plain gray wren. Note the thin white eyebrow. Found in the tangled understory of seasonally flooded Amazonian forests and adjacent clearings. The song is a loud repetition of “chu-choww” notes. Most likely to be confused with similar gray antbirds, which have shorter bills and unbarred tails.
识别特征
The grey wren is 11.5 cm (4.5 in) long. The adults have a lead-gray crown and upperparts; the tail is also gray with broad blackish bars. It has a faint whitish supercilium and the rest of the face is gray. The throat is whitish gray, the chest gray, and the belly a slightly buffy gray. It differs from others of its genus in its smaller overall size, its shorter tail, the gray plumage, and the absence of prominent facial markings.
分类信息
The grey wren, with many other Cantorchilus wrens, was originally included in genus Thryothorus, but that genus was determined to be paraphyletic. There are suggestions that the species may warrant its own genus because it is quite different from the rest of genus Cantorchilus.

分布与栖息地
The grey wren is known only from a small area of Brazil, along the right bank of the Rio Javarí and the upper reaches of the Rio Juruá and Rio Purus to the southeast. The Rio Javari forms the border with Peru but the species is unknown on that side (the left bank) of the river. It is a bird of thick vegetation, inhabiting overgrown clearings and the undergrowth of várzea forest. In elevation it ranges only as high as 200 m (660 ft).

Black-and-white Antbird
Myrmochanes hemileucus
Small antbird, black above and white below. Females have obvious white lores. Resembles a miniature Great Antshrike with a black rather than red eye. Inhabits the understory of river islands with a high density of Cecropia trees. The song is a dry trill, resembling a rattle.
Antillean Piculet
Nesoctites micromegas
A tiny, chubby woodpecker that frequents a wide variety of wooded habitats including mangroves. More prone to feed on small branches, even vines, than are larger woodpeckers. Olive-brown above and streaked below, unlike any other species in its range. Male has red on crown that female lacks. Its call is a loud burst of rapid liquid chatter.
Downy Woodpecker
Dryobates pubescens
Tiny woodpecker, common and widespread across much of North America. Black-and-white plumage is nearly identical to the larger Hairy Woodpecker. Focus on the bill: Downy has a very short bill, much shorter than the length of the head. Also note the small black markings on the white outer tail feathers. Pacific population has smaller white spots on the wing and a grayer body than Eastern birds. Occurs in any wooded habitat, though western birds are more restricted to riparian areas. Often forages on smaller branches than Hairy Woodpecker. Familiar visitor to backyard feeders, especially fond of suet. Calls include a soft “pik!” and descending rattle, weaker than Hairy Woodpecker.
