Eyebrowed Thrush
Turdus obscurus
A long, slightly curving white eyebrow gives this species an elegant, sophisticated appearance. Typically keeps to cover on the ground and in mid-levels of trees but occasionally ventures into the open to feed, particularly during migration. Alert and quick to flush. Adult male has gray head, brown back, and orange belly. Females are brownish overall with more faded orange on the underparts. Breeds in eastern Siberian forests, typically in damp areas near water, or areas with dense understory. Winters in more open habitats, such as parks, but not as fond of open spaces as blackbirds. Well-spaced song phrases consist of rich warbling and ringing buzzy whistles. Also gives a high, piercing “tsssst!”

This is an attractive thrush, with a grey back and head, the latter having a black eyeline, bordered white above and below. The breast and flanks are orange, and the belly white. The sexes are fairly similar, but immatures have a browner back.<p>The male has a simple whistling song, similar to the related mistle thrush.
分类信息
The eyebrowed thrush 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 thrushes in the genus Turdus and coined the binomial name Turdus obscurus. The scientific name comes from Latin Turdus meaning "thrush" and obscurus meaning "dark" or "dusky". Gmelin based his account on the "Dark thrush" that had been described in 1783 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. Latham noted that "This is Sibirian species and found in the woods beyond Lake Baikal" but did not explain the source of his information. The species is monotypic: no subspecies are recognised.

行为
It nests in trees, laying 4-6 eggs in a neat nest. Migrating birds and wintering birds often form small flocks. It is omnivorous, eating a wide range of insects, earthworms and berries.<p>In 2007 an eyebrowed thrush was sighted at the Jerusalem Bird Observatory in Jerusalem. This is the second recorded sighting in Israel; the first was at Eilat in October 1996.<p>In 2011, an eyebrowed thrush was sighted in Australia, near Malanda in Queensland. This is possibly the first confirmed sighting of the species on the Australian mainland.

Western Barn Owl
Tyto alba
Medium-sized owl with a heart-shaped facial disc and deep dark eyes; in parts of its range the only Tyto owl present, but compare with larger and darker-winged African Grass-Owl where overlap occurs. Varies across a wide range, but always note white-and-black speckling on the upperparts, beautiful gray-and-tawny wings, and large round head. Color of the facial disc and underparts varies from pure white to rusty orange. Hunts in open areas by night, foraging with a slow and buoyant flight. Roosts in old buildings, tree hollows, caves, and nest boxes by day. Gives a bone-chilling, rising shriek, as well as shorter rasping calls.
Eurasian Curlew
Numenius arquata
Scimitar-billed large shorebird of varied open habitats. Note large size, overall brown plumage, and long, decurved bill (appreciably shorter on juvenile). In flight shows white back patch, mostly white underwings. Common call an onomatopoeic "coor-lee." Compare to smaller Whimbrel, which has head stripes, a piping whistled call, and Far Eastern Curlew, which has a buffy rump and extensively marked underwings. Breeds mainly in grasslands, from coastal marshes to upland moors; winters mainly in coastal lowlands, especially mudflats and adjacent marshes.
Pirre Chlorospingus
Chlorospingus inornatus
Fairly small tanager-like sparrow with an extremely tiny range in the foothills of eastern Panama, from around 800–1,200 m. Distinctive in range: olive-brownish overall with brighter yellow-ochre underparts, darker blackish face, and staring pale eye. Like other chlorospingus, typically found in small groups, often with a mixed-species flock. Usually sticks to the understory or middle levels of humid forest.
