Sahel Paradise-Whydah
Vidua orientalis
A nest parasite that lays its eggs in the nests of Green-winged Pytilias. As with other whydahs, breeding males are spectacular and bizarre, whereas non-breeding males and females are drab and inconspicuous. Breeding males are mostly black, with a rufous-and-buff collar and a long tail with an odd widened area at its base. Non-breeding males and females have a brownish back, pale underparts, and a dark bill. Generally scarce and local in dry thorn savanna. Breeding male similar to other paradise-whydahs, but has a shorter tail. Non-breeding male and female can be cautiously identified by their combination of a dark bill, dull (not whitish or red) legs, and simple facial pattern. Not very vocal, but does imitate Green-winged Pytilia vocalizations.
识别特征
The males in breeding plumage have black back and wings, with a rufous breast. The head is black, with a chestnut nape and a black bill. The dual-length ornamental tail feathers are black. These tail feathers can reach a length of 195–244 millimetres (7.7–9.6 in) and a width of 24–32 millimetres (0.94–1.26 in). Feet are dark grayish. When in eclipse (non-breeding) plumage, the males are similar to the hen, as they are tawny above with narrow mantle streaking. In females a dark line extends behind the eye. Juveniles are quite similar to the hens.
分类信息
Vidua orientalis has often been considered a subspecies of eastern paradise whydah, Vidua paradisea, since both birds parasitise the green-winged pytilia, Pytilia melba, a common species of estrildid finch. However, the finch has two subspecies, nominate melba and citerior, which are sometimes treated as separate species. The ranges of these two taxa correspond well to those of V.paradisea and V. orientalis.

Golden-winged Cacique
Cacicus chrysopterus
Black-and-yellow cacique found in humid forests, montane forests, and second growth. Mostly black with a bright yellow rump and large yellow patch on the inner wing. Note the prominent white eye. A solitary nester that builds a long purselike nest. The song is variable and musical and it also makes soft whistles.
Dark-sided Flycatcher
Muscicapa sibirica
Small brown flycatcher with dark smudging on the breast and sides that lend it a “vested” appearance. Tends to prefer higher-elevation forests for breeding than Asian Brown and Gray-streaked Flycatchers but uses a variety of open forests and gardens on migration and in winter. The generally darker appearance of this species when compared to Asian Brown makes the eyering more striking.
Vermilion Cardinal
Cardinalis phoeniceus
A garish scarlet bird sporting a dramatic spiky crest and a hefty gray bill. Male overall brilliant red with black chin; female brown, gray-headed, with red crest and tail. Often found in pairs, perched in erect posture on the top of bushes or on exposed branches. Common in desert scrub and dry forests in the lowlands. Voice a melodious and slow whistled series. Unmistakable in arid regions of northern Venezuela and extreme northeastern Colombia.
