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:
- 迁徙
- Complete migrants
行为
These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects and aquatic animals.<p>Baillon's crakes are very secretive in the breeding season, and are then mostly heard rather than seen. They are then noisy birds, with a rattling call like that of the edible frog, or perhaps garganey. They can be easier to see on migration or when wintering.

Flame-templed Babbler
Dasycrotapha speciosa
A small bird from lowland to low-elevation montane forest and edge on Panay and Negros. Has a gray back with fine pale streaks, golden flight feathers, a yellowish belly, a brighter yellow chest extending around the collar, a black head with black spots on the upper chest, and a yellow bill, forehead, chin, and short moustache stripe. Note the white-streaked cheek and the orange tufts on the back of the head. Often joins mixed-species flocks, where it methodically forages in the understory and at middle heights in the forest. Unmistakable. Song is a descending whistled warble.
White-browed Purpletuft
Iodopleura isabellae
Attractive, small, chocolate brown-and-white bird of lowland rainforest. Bold facial pattern is distinctive; purple tufts on the flanks are often hidden, but diagnostic when visible. Usually perches singly or in pairs high up in the forest canopy, and can be easiest to see around the edges of forest clearings. Fairly quiet, usually giving only high, unobtrusive “seet” notes.
Gray-backed Hawk
Pseudastur occidentalis
An endangered raptor found only in western Ecuador and immediately adjacent parts of Peru. It has white underparts, dark gray back and wings, and gray streaks on the head. Its tail is white with a thick black band near the tip that is especially evident in flight. Restricted to areas where extensive forest cover remains. Prefers dry and semi-humid areas; not normally present in the wetter forests of northwestern Ecuador, but may occasionally wander into them.
