Congo Martin
Riparia congica
A typical small martin with brown upperparts, pale underparts, and a diffuse gray-brown breast band. Resident and extremely localized, restricted to the Congo River and a handful of its tributaries, breeding colonially in sandbanks. Despite being fairly common, the species’ vocalizations are unknown. Sand Martin is larger than Congo Martin and has a bolder breast band delineating a white throat; Brown-throated Martin has a dark throat.
识别特征
The 11 cm long Congo martin is light brown above with a slightly darker crown and wings. It has a dark line through the eye. The underside of the body is white except for a pale brown breast. It does not have the distinct narrow breast band shown by the sand martin. The bill is black and the legs are brown. Sexes are similar, but the young have pale tips to the feathers on the back, rump and wings.<p>The call has not been recorded.<p>Although the indistinct breast band of the Congo martin is different from the clearly defined markings of the sand martin, in practice it is not easy to distinguish the resident species from the winter migrant.

Lesser Adjutant
Leptoptilos javanicus
A large stork with a completely bare head and neck ideal for its scavenging habits. The adult’s face is red and the neck is yellow while the juvenile has a brownish head and a white, thinly-feathered neck. The upperparts are all dark while the underparts are mostly white. In flight, note the broad wings with distinctive white “armpits” and tucked in neck. Similar to the larger Greater Adjutant; Lesser has a more slender bill, has all-dark upperwings, and often adopts a more upright, less “hunched” posture. Often found in shallow marshes, fields, and swamps.
White-shouldered Fire-eye
Pyriglena leucoptera
Medium-sized antbird found in the understory of humid forests, second growth, and plantations. Often follows army-ant swarms and mixed-species flocks. Males are black with white shoulders and 2 white wingbars. Females are rufous-brown above and paler below. Both sexes have red eyes.
New Zealand Scaup
Aythya novaeseelandiae
New Zealand endemic diving duck. Widely but patchily distributed throughout North and South Islands; not found on Stewart Island, and no longer present on Chatham Islands. Unlike any other resident duck species. Compact and dark; floats on water with cork-like buoyancy, showing bath-toy duck silhouette. Forms large flocks, often congregating in sheltered areas near willows or reed beds. Spends a lot of time underwater, where it can travel considerable distances. Sexes alike but distinguishable. Male has dark black plumage, iridescent blue-green head and wings, and yellow iris. Female is duller brown with brown iris. Flies with very fast wingbeats, often just above the water’s surface. Vagrant Hardhead differs in its white iris, white undertail, and white “saddle” on bill.
