Chinese Leaf Warbler
Phylloscopus yunnanensis
Small plump leaf warbler. A “Pallas’s-type” leaf warbler: stout, with a pale rump, crown stripe, and prominent brow stripes. Olive-yellow above with a faint gray wash on the nape. Chinese is distinguished from Pallas’s by its paler, more faded-looking brow and crown stripes, less yellow suffusion all over the body, less compact appearance, and less obvious or absent upper wingbar. Extremely similar Gansu Leaf Warbler and Lemon-rumped Warbler can be difficult to separate; note Chinese’s slightly more elongated and less rounded appearance, a lack of a distinct hook under the end of the brow stripe, less contrasting and more yellowish head patterning, and paler yellowish secondaries. Forages actively, often hovering and hopping about at mid-level. Breeds in montane broadleaved deciduous or mixed forest; moves to lower elevations in winter. On average, found at lower altitudes than Lemon-rumped and Gansu. Lengthy song is unique and bizarre, with a twanging, grating quality: “btrichi-btrichi-btrichi.” Call is an explosive “wip!”, often repeated in medium-length series on the breeding grounds.
识别特征
The Chinese leaf warbler is a brightly colored, small leaf-warbler, with a total length of around 10 cm and a wing length of 5–6 cm. Its body is slightly elongated and compact. The warbler has a slightly forked or notched tail that is almost square in shape. Its bill is pointed and short (around 1 cm long) and dark brown in color, brownish-yellow on the underside. The wings are very short and rounded, the legs slender and very dark. Claws and toes are dark brownish-grey with dusky buff undersides.<p>Birds generally go through variations in the appearance of their plumage, depending on the stage in their life, the seasons or nutritional intake. In the spring season, this warbler in its adult phase has a new, fresh, or bright appearance already somewhat dulled. In the adult summer phase its feathers appear worn, or duller.<p>The sexes are similar in appearance. The Chinese leaf warbler is pale green to olive-green above and has a yellowish-white rump. The head pattern is noticeable and striking in appearance, with a well-defined pale eyebrow stripe, a faint yellow median crown stripe and dusky-olive lateral crown stripes. The tertial feathers are sepia-colored and have whitish tips. The eye is surrounded by a broken eyering; the iris of the eye is dark brown.

行为
Chinese leaf warblers can be found singly or in pairs during the breeding season. These birds are generally somewhat bold in personality. They almost always keep to tree canopies, where they feed on insects. Males also sing from the tops of trees.<p>The Chinese leaf warbler has a unique song compared to other species of its genus. The song often lasts over a minute and is dry and monotonous tsiridi repeated five times. The call note is loud and varied, an irregular series of clear scolding whistles of tueet repeated five times, then four series of decreasing lengths, finishing up with another 5-fold note. The last phrase can be a hammering tueet-tuee-tee, with a seven-fold tee. The close-range call is a soft trr-trr.

Brown Woodland-Warbler
Phylloscopus umbrovirens
Small brownish warbler. Dull greenish on the back and buffy brown below. The bright yellow-green edges to the wing feathers can be conspicuous. Found in montane forest, mostly in the mid-story and canopy. Like other woodland-warblers, active and always on the move. The distinctive song consists of quick up-and-down series which are repeated with slight variations after a short pause. Similar to Red-faced Woodland-Warbler, but darker on the belly, with less red on the face and throat.
Red-headed Bluebill
Spermophaga ruficapilla
Pretty member of the waxbill family that has a massive, conical bill. Males have a black belly and females a spotted one, and both sexes show an all-red head. Found in rainforest, gallery forest, thickets, and secondary habitats. Usually in pairs or small groups, in areas with thick undergrowth, and usually some grass. Sometimes on roads and paths. Vocalizations include a quiet “schpit” call and a rarely-heard whistled song. Similar to Grant’s Bluebill, but separated by all-red head. Male similar to male Black-bellied Seedcracker, but separated by its black tail and its red-and-blue rather than all-blue bill.
Black Wood-Pigeon
Columba janthina
The largest pigeon in the region, with dark purplish plumage except for metallic green around the neck. Generally uncommon endemic of islands off Japan, and to a lesser extent South Korea and Taiwan. Occurs in mature broadleaf forests, where it forages on the ground or in canopy. Also favors pines, especially in the Ryukyu Islands. Rustles about loudly when feeding. Deep call and slow moaning song may recall the everyday Rock Pigeon.
