Senegal Coucal
Centropus senegalensis
Small coucal with a black cap and buffy underparts. There is a localized West African population that shows black underparts, save for a rufous belly. Found in a variety of habitats with a thick understory, including tall grassland, scrub, thickets within savanna, and forest edge. Skulks in the undergrowth, occasionally emerging to sit on an exposed perch, especially when drying out after a rainstorm. Song is a descending and accelerating series of deep “boop” notes. In the small area of overlap with Burchell’s Coucal, separated by the plain black rather than barred top of the tail. Immature has a streaked back and resembles White-browed Coucal but is more rufous below. Much smaller than Black-throated and Coppery-tailed Coucals.
识别特征
This is a medium-sized species at 39 cm (15 in) in length. Its crown, nape and upper parts, bill, legs and long tail are black, the eyes are red, the wings are chestnut, and the underparts are creamy white, with blackish barring on the flanks. The sexes are similar, but juveniles are browner and more heavily barred above, with buff to cinnamon, barred and streaked underparts.
分类信息
In 1760, the French zoologist Mathurin Jacques Brisson included a description and an illustration of the Senegal coucal in the fourth volume of his Ornithologie based on a specimen collected in Senegal. He used the French name Le coucou de Sénégal and the Latin name Cuculus Senegalensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766, the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson in his Ornithologie. One of these was the Senegal coucal. Linnaeus included a terse description, coined the binomial name Cuculus senegalensis and cited Brisson's work. The Senegal coucal is now one of around 30 species placed in the genus Centropus that was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The genus name combines the Ancient Greek kentron meaning "spur" or "spike" with pous meaning "foot".<p>Three subspecies are recognised:

分布与栖息地
It is a widespread species distributed through much of central and southern Africa south of the Sahara Desert. The range extends from Senegal in the west to Ethiopia and Kenya in the east, and Angola and Congo to the south. A separate population in southern Africa is centred on Zambia, Zimbabwe and northern Botswana. The Senegal coucal is a bird of grassy habitats with trees, such as bushes and savannah.

行为
The Senegal coucal takes a wide range of insects, caterpillars and small vertebrates. It occasionally eats other food items. It nests off the ground in low vegetation, and the typical clutch is two to four eggs laid in a large nest built from stalks and leaves.

Water Pipit
Anthus spinoletta
Breeding plumage grayish above with white eyebrow; breast pale pinkish, mostly unstreaked. Nonbreeding plumage grayish brown above, whitish below with dark streaks; averages smudgier and less well-marked than American Pipit. Sides of tail clean white; compare with dingy white of Rock Pipit in areas of overlap. Song is a long series of repeated high-pitched notes; essentially a slow trill. Call a high, lisping, slightly upslurred "ssiip.” Breeds in mountains on barren, often rocky ground; winters in varied wetland habitats, from lakeshores to salt marshes.
Cayenne Jay
Cyanocorax cayanus
Large jay of humid forest and edges including savanna and premontane forest in the tepui region. Combination of size and black-and-white plumage unlike any other species in range. Moves through forest in noisy groups but can be hard to see well. Sometimes accompanies foraging flocks of oropendolas and caciques, feeding on flowers and fruit. Calls include a variety of whistles and grunts.
Oasis Hummingbird
Rhodopis vesper
Small hummingbird of desert lowlands and foothills. Found in gardens, agricultural areas with flowers, and native scrub; often fairly common. Best identified by combination of rather long arched bill and pale rusty rump patch; appreciably larger than most other superficially similar hummingbirds in its range, such as Peruvian Sheartail. Male has a magenta-rose gorget (often messy and incomplete). Female is drab whitish below with duskier sides.
