Coppery-tailed Coucal
Centropus cupreicaudus
Huge coucal with a hefty bill. The head and tail usually look black, but can show a coppery or purplish sheen in certain light. Found in thick wetlands, especially papyrus. Fairly skulking, though occasionally seen in the open. Massive size is obvious in flight. The call is a slow, deep version of the typical coucal descending and accelerating series of “boop” notes. Very similar to Blue-headed Coucal, but there is virtually no overlap in range, and Coppery-tailed is larger, without a blue sheen to the head. Burchell’s and Senegal Coucals have a similar pattern, but are much smaller.
识别特征
An adult coppery-tailed coucal is about 48 cm (19 in) long and has a curved beak and long, broad tail. Males are slightly smaller than females. The coppery-tailed coucal's plumage is similar to that of the Senegal coucal (Centropus senegalensis). It has a black head and upperparts, white or cream-coloured underparts, a brown rump with a coppery-sheen and a blackish-brown tail. Immature birds have pale streaks on the head and their flight feathers are barred. The call of the coppery-tailed coucal consists of deep, bubbling notes.

分布与栖息地
The coppery-tailed coucal is native to parts of south central Africa. Its range stretches from Angola in the west to southwestern Tanzania, northern Botswana and the Caprivi Strip in Namibia. Its typical habitat is swampland and dense vegetation near rivers, but it is also found on inundated floodplains and near seasonal lakes. The total size of its range is around 1,750,000 square kilometres (680,000 sq mi).

行为
The coppery-tailed coucal is territorial throughout the year and is mostly active soon after dawn and in the evening. It forages on land and feeds on amphibians, fish, small birds, reptiles and rodents as well as such invertebrate prey as grasshoppers, crabs and snails. It scavenges for dead fish and other edible matter and eats some green plant food. It tears open the nests of weaver birds (Ploceus spp.) and sometimes swallows blue quail (Coturnix adansonii) whole. The breeding season occurs from January to March and the bird is believed to be monogamous. A domed nest, built of grasses, reed fragments and twigs and lined with leaves, is constructed low down among reeds or in tangled waterside vegetation. Both parents are involved in nesting activities but the male may play the larger role. A clutch of two to four eggs is laid and incubation starts as soon as the first egg is laid, which is sometimes before the nest has been completed. The eggs hatch at intervals and both parents care for the young. The chicks are fed on such foods as frogs and locusts. The young leave the nest when about seventeen days old, sometimes when part grown and not yet able to fly.

Rufous-breasted Sabrewing
Campylopterus hyperythrus
Large, conspicuous hummingbird of tepui highlands. Green above and rufous below. Note extensively rufous outer tail feathers, which are easily seen as birds tend to flare tail frequently. Generally common at higher elevations (above 1000 m), especially at forest edge and in lower-stature, scrubby vegetation. Feeds on nectar and pugnaciously defends patches of flowers against other hummingbirds. Not shy and will approach to investigate observers. In territorial interactions, gives a rich, sharp note, often doubled, repeated incessantly, and similar to calls of more widespread Gray-breasted Sabrewing; also gives a single, ascending, burry note, possibly as an alarm call. No other hummingbird in highland range is as large or shows as much rufous.

Two-banded Warbler
Myiothlypis bivittata
Small, yellowish bird with a fine black bill and distinctive black stripes on head. Mostly green above and yellow below; has rufous or orange crown bordered by black, but crown color can be difficult to ascertain. Note olive eyebrow becoming yellow in front of eye, and bright pinkish-yellow legs. Inhabits dense understory of foothill forests along the eastern slope of the southern Andes and in the tepui region. Usually occurs in pairs or small family groups that forage actively for insects, often joining mixed-species flocks. Song in tepuis is a series of chips followed by a high-pitched, screeching note. In southern part of range, song is very different: a rich rollicking series of notes that may vaguely recall House Wren and is often given by pairs as a duet. In southern Andes, most similar to Golden-bellied Warbler but has olive (not entirely yellow) eyebrow; also similar to Golden-crowned Warbler but typically occurs at higher elevations and has olive (not whitish) eyebrow.

Bronze Ground Dove
Pampusana beccarii
A rotund, short-legged ground-dwelling dove that usually runs rather than flies when startled. Both sexes have a brown body with bluish-gray chest and head. Males have an iridescent pink shoulder patch. Most obvious identification feature in the field is the glowing white eye-ring of the male, especially in more eastern populations such as those in the Solomon Islands. On mainland New Guinea, the species is a resident of upper-elevation montane forest. No other similar species occur in its altitudinal range. Gives a typical dove-like “woo-oop” call which is quiet and easily missed.
