Wattled Jacana

Jacana jacana

Striking marsh bird, medium-sized with exceptionally long toes. In some regions adult is entirely black; other populations more similar to Northern Jacana with rufous upperparts. Always has red forehead and wattle at base of bill. Juveniles very similar to Northern Jacana: bronzy-brown above with white underparts and eyebrow; note yellow bill and long toes to separate from other marsh birds. All ages show yellow wings in flight. Found in wetlands, usually with a combination of grasses and lily pads.

识别特征

These are conspicuous and unmistakable birds. They are 17–23 cm (6.7–9.1 in) long, but the females are larger than the males. The adults have a chestnut back and wing coverts, with the rest of the body mainly black. In flight the greenish yellow flight feathers are obvious. Also visible are yellow bony spurs on the leading edge of the wings, which it can use to defend itself and its young. The yellow bill extends up as a red coot-like head shield and a reddish wattle, and the legs and very long toes are dull blue-grey.<p>Young birds initially have entirely white underparts, and can always be identified by the presence of white in their plumage.

分类信息

There are six subspecies, with the nominate J. j. jacana being the most widespread. Several of the other subspecies are similar, but J. j. hypomelaena of western Panama and northern Colombia has all the chestnut plumage replaced by black, and J. j. scapularis of western Ecuador has some black feathers on its chestnut shoulders, and white outer primary feathers.<p>This species produces a range of noisy rattling calls.

Burhinus grallarius

Distinctive large shorebird with long legs, enormous yellow eye, heavily streaked underparts. During the day stands or sits under small trees/shrubs, often in small groups.

Sulawesi Ground Dove

Gallicolumba tristigmata

A stocky, short-tailed forest pigeon. Shows a diagnostic head pattern, with yellow forehead, green upper nape, and burgundy collar. Back, wings, and tail dark brown, with gray outer tail feathers. Underside grayish, with soft yellow wash on the breast. Juvenile browner, with rusty edges to feathers. Singles or pairs forage on the floor inside montane forest. Typically runs away rather than flying. Restricted to Sulawesi island, where no other similar species occur. Gives a deep hooting call, sometimes with a barely audible introductory note: “whooo-whooo” or “w-whooo-w-whooo.”

Bedford's Paradise-Flycatcher

Bedford's Paradise-Flycatcher

Terpsiphone bedfordi

An unusual paradise-flycatcher, slate-gray overall with a slightly darker head. Males have slightly elongated central tail feathers. Both sexes have a blue bill and ring around the eye. A poorly known bird that is found in humid forest at lower middle elevations along the west side of the Albertine Rift. Similar in shape to other paradise-flycatchers, but easily separated by the gray underparts. Reminiscent of Dusky and Blue-headed Crested-Flycatchers, but larger and less crested, with more vertical posture. Call is a series of tearing “shreet” notes, and song is a fast, bubbling series of “twee” notes.
