Tufted Antshrike
Mackenziaena severa
Medium-sized antshrike, with a long tail and a crest. Found in the understory and middle levels of humid forests with dense vine tangles or bamboo and in second growth areas. Usually found in pairs, but can be very hard to see. Males are all dark-gray whereas females have a cinnamon crest and bars on the rest of the body. The song is a loud and clear series of whistles “phiu phiu phiu phiu phiu.”
识别特征
The tufted antshrike is a large dark antbird, 20 to 23 cm (7.9 to 9.1 in) long and weighing 50 to 80 g (1.8 to 2.8 oz). The species exhibits significant sexual dimorphism, though both sexes have a crest (that usually is flattened), red irises, and a moderately long black bill with a hook at the end like true shrikes. Adult males are mostly sooty gray with a blackish forehead and crest and browish black wings. Adult females are mostly blackish brown. Their forehead and crest are rufous, their upperparts have cinnamon bars, their tail has faint paler bars, and their underparts have pale buff bars. Subadult males resemble adult males but are more brownish overall.
分类信息
The tufted antshrike shares genus Mackenziaena with the large-tailed antshrike (M. leachii). However, there is some doubt about how closely they are related, with evidence that the tufted antshrike is more closely related to the three species of genus Frederickena. Both species are monotypic.

行为
The tufted antshrike is presumed to be a year-round resident throughout its range.<p>The tufted antshrike feeds on a variety of large insects and other arthropods; its diet also includes molluscs and small vertebrates including frogs, lizards, snakes, bird eggs and nestlings. It forages singly or in pairs, mostly within about 3 m (10 ft) of the ground but as high as 10 m (35 ft) in dense bamboo and vine tangles. It hops from branch to branch and along the ground, reaching from a perch to glean prey from leaves, stems, and branches. It occasionally drops to the ground to seize prey.<p>The tufted antshrike's eggs have been described as having a clear base color with dark lilac spots ang gray lines. Nothing else is known about the species' breeding biology.<p>The tufted antshrike's song is a "short, slow, slightly accelerating series of 6-8 very high, slightly rising, strident 'sreek' notes". Its call is a "sudden rising shriek, like 'sreeew' ".

Tawny-bellied Babbler
Dumetia hyperythra
Bright orange-brown babbler, brighter-colored than any similar babblers. Stays away from dense mature forests, instead favoring forest edges, open woodlands, dense scrub, and grassy areas interspersed with trees. Song is a short series of moderately-spaced high sibilant whistles. Call repertoire ranges from high thin notes to noisy yapping.
Blue Pitta
Hydrornis cyaneus
Only the male of this rotund ground-dweller is truly blue; the female only has a hint of blue on the rump and tail. Male is brilliant and eye-catching if seen well: sky-blue on the back with a polka-dotted light blue breast and belly. Female has gray-brown wings and finely barred white underparts. Both sexes boast a pale face and a thin black eyebrow, above which flames a lava-red crown (darker in males than in females). Forages on the densely-vegetated floor of forests from the lowlands up into montane regions, often in gorges, in ravines, and near streams. Song is a liquid ‘cho’mew-wit!’, with a clipped-sounding last note.
Brambling
Fringilla montifringilla
Distinctive and handsome orange-breasted finch. Note black head of males (solid in breeding season, patchy in non-breeding) and gray-and-brown head of females. Complex wing patterns and white rump patches create a wondrous show when a flock rises up in flight. Breeds in northern woodlands, especially in and around birches; winters in varied wooded habitats (especially with beech trees), semiopen country, and farmland with hedges; sometimes visits gardens and parks with feeders or fruiting trees. Song is surprising and almost ugly for such a well-marked finch, a strange ringing buzz: “eerRRRRNnnn.” Gives a rising “qweee”, a higher-pitchd “tsi, tsi”, and various twittering and nasal flock calls.
