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.

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.

Philippine Eagle-Owl
Ketupa philippensis
A large owl of lowland and foothill forest, including secondary habitat and plantations. Warm brown with a heavily marked back, a heavily streaked rufous head and chest, and a more sparsely streaked pale belly. Note the square-shaped head with flattened ear tufts and the yellow eyes. Unmistakable. No other owls of similar size occur in its range. Gives a long, drawn-out, spooky whistled note whose pitch rises slightly, then falls at the end.
Black-faced Babbler
Turdoides melanops
Dull brownish babbler with a pale eye. Found very locally in areas of thick mixed savanna. Almost always in small groups, which feed by hopping across the ground. Raucous babbling call is frequently given, usually by a whole group in chorus. Similar in shape, size, and overall brown coloration to Arrow-marked Babbler, but easily separated by pale eyes, black lores, and broad and messy markings below. Also easily separated from Hartlaub’s Babbler by the white eye and dark rump.
Vegetarian Finch
Platyspiza crassirostris
A large and rather parrot-billed Galápagos finch. Bill is about as long as it is deep, with a very round upper edge and slightly curved lower edge. Male has a black hood and bill, a sooty back, and a yellowish belly with dark streaks. Female is tan with a pale bill, a whitish or yellowish belly, and brown streaks on the underparts. Very similar to Large Tree-Finch, which is smaller and smaller-billed. Most likely to be encountered in forest at middle elevations on the larger islands. Not present on the islands of Española, Genovesa, and Santa Fé.
