Barred Tinamou
Crypturellus casiquiare
Very rare and poorly known tinamou of remote lowland rainforest. Existing records suggest that it favors areas with sandy soil. Rather small for a tinamou, with a chestnut head, a black back, wings marked with rusty bars, dingy underparts, and a pale throat. Few birders have ever seen it, and even hearing one requires some luck. Song is a series of whistles that starts out by accelerating and rising slightly in pitch, then slows down and falls towards the end.
识别特征
The barred tinamou is approximately 25 cm (9.8 in) in length. It is yellowish-buff with heavy bars of black on its back, its throat is white, its front and sides of neck and breast are pale grey, its belly is white, its flanks are cream barred with black, and its head and neck are chestnut in color with legs that are olive-green. The female is paler on back.[citation needed]
分类信息
This is a monotypic species. All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.

行为
Like other tinamous, the barred tinamou eats fruit off the ground or low-lying bushes. They also eat small amounts of invertebrates, flower buds, tender leaves, seeds, and roots. The male incubates the eggs which may come from as many as 4 different females, and then will raise them until they are ready to be on their own, usually 2–3 weeks. The nest is located on the ground in dense brush or between raised root buttresses.
保护状况
The IUCN classifies the barred tinamou as Least Concern, with an occurrence range of 49,000 km2 (19,000 sq mi).

Philippine Bush Warbler
Horornis seebohmi
A small drab bird of dense undergrowth within open montane forest in northern Luzon. Warm brown on the upperparts and crown with a dark eye-stripe and pale brown underparts blending to a pale gray chest and whitish throat. Similar to Long-tailed Bush-Warbler, but tail shorter and underparts grayish rather than deep brown. Also similar to Benguet Bush-Warbler, but has a a more distinct pale eyebrow. Song consists of a drawn-out low whistle followed by an explosive whistled phrase. Call is a sharp “tsik!”
Eurasian Blackcap
Sylvia atricapilla
A rather distinctive and bulky warbler: male plain grayish overall with eponymous black cap; female and juvenile plain, slightly browner overall, with rusty-brown cap. Inhabits wooded and scrubby habitats, including gardens, sometimes visiting feeders in the winter. Small numbers winter in Western Europe, but most migratory birds move south to Africa and the Mediterranean region. Song is a varied, rather loud rich warble, often strident. Often gives a harsh “chakchak” call, usually in series. Rare dark morph with black-hooded male and brown-hooded female can be found on the Atlantic Islands and very scarcely elsewhere.
Ochre-breasted Foliage-gleaner
Anabacerthia lichtensteini
Medium-sized foliage-gleaner with a short bill and attractive head pattern giving it a “cute” look. The crown and mask are gray-brown contrasting with a buffy-yellow eyebrow and throat. Buffy and unstreaked below and rufous-brown above. Found in the upper levels of forests and second growth. The song is a short fast trill.
