Hermit Thrush

Catharus guttatus

Medium brown above with contrasting reddish tail. Dark spots on breast do not continue all the way down belly like Wood Thrush. Found in wooded areas; often hops on the ground or skulks in dense patches of shrubbery. Winters further north than other thrushes; many stay in the U.S. Listen for its beautiful song that is higher pitched than other thrushes with a steady introductory note; also gives low "chup" call note.

识别特征

This species measures 15 to 18 cm (5.9 to 7.1 in) in length, spans 25 to 30 cm (9.8 to 11.8 in) across the wings and weighs 18 to 37 g (0.63 to 1.31 oz). Among standard measurements, the wing chord is 7.8 to 11.1 cm (3.1 to 4.4 in), the bill is 1.6 to 1.9 cm (0.63 to 0.75 in) and the tarsus is 2.7 to 3.3 cm (1.1 to 1.3 in). It is more compact and stockier than other North American Catharus thrushes, with relatively longer wings. The hermit thrush has the white-dark-white underwing pattern characteristic of Catharus thrushes. Adults are mainly brown on the upperparts, with reddish tails. The underparts are white with dark spots on the breast and grey or brownish flanks. They have pink legs and a white eye ring. Birds in the east are more olive-brown on the upperparts; western birds are more grey-brown.[citation needed]

行为

Hermit thrushes breed in coniferous or mixed woods across Canada, southern Alaska, and the northeastern and western United States. They make a cup nest on the ground or relatively low in a tree.<p>While most hermit thrushes migrate to wintering grounds in the southern United States and south to Central America, some remain in northern coastal US states and southern Ontario. Identification of spotted thrushes is simplified by the fact that hermit thrush is the only spotted thrush normally found in North America during winter. They usually breed in forests, but will sometimes winter in parks and wooded suburban neighborhoods.<p>They are very rare vagrants to western Europe and northeast Asia.<p>They forage on the forest floor, also in trees or shrubs, mainly eating insects and berries.

Cinnamon-crested Spadebill

Cinnamon-crested Spadebill

Platyrinchus saturatus

A tiny flycatcher of forest understory. Generally difficult to see. Notably plain: brown above and yellowish-white below with a semi-concealed chestnut crown that is not visible under most field conditions. Note small size, plain face, and wide bill characteristic of spadebills. Inhabits understory of lowland rainforest, where it perches in low vegetation and makes short upward sallies to nab insects on the undersides of leaves. May follow mixed-species flocks but is more often found away from them. Most frequently heard call is a short, inflected squeak, often given in alarm as the bird flies away; song is a surprisingly loud, grating series of notes. Best told from other spadebills by plain plumage and lack of strong facial pattern.

Lemon-breasted Seedeater

Lemon-breasted Seedeater

Crithagra citrinipectus

A small gray-brown seedeater with a lemon-yellow rump, white tail tips, and a boldly marked face with pale patches (white to lemon-yellow) above and below the eye. The throat and upper breast are lemon-yellow in the male and buff in the female. Pairs and small flocks occupy savanna, grassland, and palm savanna, where the species is partial to Ilala Palm. It forages on the ground and in small shrubs and grass. The similar Yellow-fronted Canary is yellower, has a broader eyebrow, and lacks wingbars and the vertical dark stripe below the eye.

Sumatran Green-Pigeon

Sumatran Green-Pigeon

Treron oxyurus

Relatively plain and unmarked green-pigeon with a long pointed tail. Males have a faint orange blush on the chest, though this can be hard to notice. Note blue-green bill and “goggles” in both sexes. Completely unmarked dark olive-green wings separate this species from other green-pigeons within its range; Wedge-tailed Green-Pigeon can be similar, but note that species’ much more thickset build and shorter tail. Endemic to the hill forests of Sumatra and western Java. Like other green-pigeons, gathers in fruiting trees. Gives rising and falling series of high-pitched coos, often with a hiccuping or sobbing quality.
