Forest Wagtail
Dendronanthus indicus
A distinctive wagtail with diagnostic wing and breast patterns. It has a prominent, whitish eyebrow with two black crescent-shaped bands on the upper breast; lower one wider when present. Upperparts are brown-gray with a greenish tinge. Two broad white wingbars on an otherwise black wing. Immature is browner, less green above than adult, the breast-bands brownish-black and narrower, the lower one completely or partially missing. Inhabits all kinds of woodlands, foraging on forest paths, swinging its tail side to side (not up and down), and when disturbed, flushing into trees. Call is a metallic “pink” produced in flight. Song is a two-noted “tis-fee” repeated 4-5 times.
识别特征
This is a distinctive wagtail, the only one placed in the genus Dendronanthus (all other wagtails are placed in Motacilla). The forest wagtail is 18 cm (7.1 in) in length, a slender bird with a long tail. The back and crown are olive brown, and the wings are black with two yellow wing bars and white tertial edges. There is a white supercilium, above a dark stripe through the eye. The underparts are white, apart from a black double breast band. The upper breast band is bib-like while the lower band is often broken. The sexes are similar in appearance. Young birds are more yellowish on the underside.<p>The forest wagtail has a single-note call ('pink pink') given often while on the ground or even in high flight. In addition, the birds have a soft lilting song. The brown shrike (Lanius cristatus confusus) sometimes imitates the calls of the forest wagtail.

The forest wagtail was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla indica. The specific epithet is from Latin indicus meaning "Indian". Gmelin based his account on "La Bergeronnette gris des Indes" that had been described in 1782 by the French naturalist Pierre Sonnerat. The forest wagtail is now the only species placed in the genus Dendronanthus that was introduced in 1844 by the English zoologist Edward Blyth. The name Dendronanthus combines the Ancient Greek dendron meaning "tree" with the genus Anthus that was introduced for the pipits by Johann Matthäus Bechstein in 1805. The species is monotypic: no subspecies are recognised.

分布与栖息地
As its English and scientific names imply, this is a forest species, a distinction from all other wagtails. It is usually found in open areas of the woodland such as clearings. In winter it is found mainly in well-shaded forest habitats or along paths in coffee plantations and clearings in forests.<p>The breeding areas are in eastern Asia, parts of Korea, parts of China (Gansu, Anhui, Hunan) and parts of Siberia. Southern records of breeding from Assam have been questioned. It migrates to the warmer parts of Asia in winter and it has been suggested that they reach southern India and Sri Lanka via the Andaman Islands. It has been recorded as a vagrant in the Maldives and Australia.<p>It was formerly thought to winter only in southwestern India, passing through the rest of the peninsula on migration. But now it has been shown to winter in all of the southern part of the peninsula in addition to southwestern India.

行为
These wagtails are found singly or in small groups. They often forage in the trees and capture insects along the branches of trees. They may also forage on the ground like a pipit and when disturbed, it flies up into the trees with a sharp pink note. They can climb steep branches and will run rapidly along horizontal branches. They roost in the company of other wagtails among reeds.

Agile Tit-Tyrant
Uromyias agilis
A small, relatively long-tailed flycatcher found in the Andes from western Venezuela to southern Ecuador. Usually looks disheveled with messy streaking below, a diffuse white eyebrow, and a darker mask. Note the absence of wingbars. Also note pale lemon-yellow belly and slight shaggy crest (usually held down). Typically found in small flocks that forage actively in the understory, sometimes following a mixed-species flock. Not particularly difficult to see, although sometimes stays hidden in a patch of bamboo. Occurs in scrubby temperate forest and edges from around 2,600 to 3,500 m. Listen for trills and excited squeaks.
Colima Warbler
Leiothlypis crissalis
Rather drab warbler of highlands in Mexico. Dusky gray-brown overall with grayer head, bold white eyering, buffy flanks, and mustard-yellow undertail coverts. Sings from atop bushes and small trees, but otherwise rather skulking, generally staying low and well-hidden. Does not join mixed-species flocks. Breeds in oak scrub and thickets within mountainous pine-oak forest. Winters in brushy flower banks and tangles within pine-oak forest. Breeding range barely enters the U.S. in the Big Bend region of Texas.
Screaming Piha
Lipaugus vociferans
One of the most characteristic sounds of Amazonian lowlands. This drab gray cotinga is commonly heard but infrequently seen throughout its range. Perches inconspicuously in the midstory but is betrayed by its song, a quiet introductory series of hoots followed by an ear splitting “SQUEE, SQUEE-AH.” Similar to Grayish Mourner, but is larger and lighter gray, with a larger, broader bill.
