Baillon's Crake
Zapornia pusilla
Widespread across Africa, Eurasia and Australasia. Tiny crake that breeds in wet sedge marshes and bogs; migrants can be in any marshy habitat. Usually retiring and rarely seen, but can be confiding. Although unmistakeable in parts of its range, it can sometimes co-occur with the similar Little Crake. Best told by its shorter wings, short, greenish bill that lacks red base and barred flanks; juvenile darker and more extensively barred below than juvenile Little Crake.
识别特征
They are 16–18 cm (6.3–7.1 in) in length, and are similar to the only slightly larger little crake. Baillon's crake has a short straight bill, yellow or green without a red base. Adults have mainly brown upperparts with some white markings, and a blue-grey face and underparts. The rear flanks are barred black and white. They have green legs with long toes, and a short tail which is barred underneath.<p>Immature Baillon's crakes are similar to the adults, but have extensively barred underparts. The downy chicks are black, as with all rails.

分布与栖息地
Their breeding habitat is sedge beds in Europe, mainly in the east, and across the Palearctic. They used to breed in Great Britain up to the mid-19th century, but the western European population declined through drainage. There has been a recovery in north-western Europe in recent years, with the recolonisation of Germany and the Netherlands, and breeding suspected in Britain; an Irish record in 2012 was the first there since the 1850s. They nest in a dry location in wet sedge bogs, laying 4–8 eggs. This species is migratory, wintering in east Africa and south Asia.<p>It is also a resident breeder in Africa and Australasia. There is a single North American record of this species on Attu Island in September 2000.<p>There are at least five subspecies of Baillon's crake:

Guttulate Foliage-gleaner
Syndactyla guttulata
Streaked, rufous-brown bird, medium-sized with upturned bill, buffy eyebrow and throat, and long, rufous tail. Obvious buffy streaks on head, back, and underparts. Sexes similar. Fairly common (easiest to find by voice) in dense understory of cloud forest from medium to high elevations, often in bamboo patches. Usually alone or in pairs or mixed species flocks foraging at low levels, moving fast and examining bromeliads and dry leaves. Call is a harsh, nasal note; song is a series of accelerating, harsh, and noisy notes. Endemic to the Coastal Cordillera of Venezuela.
Marsh Tapaculo
Scytalopus iraiensis
Small, dark ash-gray tapaculo. Note the unbarred dark brown vent. Occurs in marshy areas with dense tall grasses and sedges, where usually devilishly difficult to see. The song is a long (c. 30 seconds) repetition of “tchek” notes.
Rufous-vented Grass Babbler
Laticilla burnesii
Specialized, slender prinia-like babbler. Restricted to lowland grassy riverine plains, where it typically stays low in the vegetation in small flocks, flushing only reluctantly. If seen, note very long tail, white throat, and streaking all over the body. Shy and difficult to see; more readily detected by its bubby, warbling song.
