Abyssinian Roller
Coracias abyssinicus
A slim and beautiful roller with very long outer tail feathers. In flight, the spectacular wings are half pale blue and half dark blue. Found in dry savanna and other open country. Usually seen singly or in pairs. Easily separated from Lilac-breasted Roller by the blue throat. Occasionally lacks elongated outer tail feathers, and then very similar to European Roller, but separated by the dark blue rather than black outer wing. The calls are rough rasps.
识别特征
The Abyssinian roller is a large bird, nearly the size of a jackdaw at 28–30 cm (11–12 in). It has a warm brown back, with the rest of the plumage mainly blue. Adults have 12 cm (4.7 in) long tail streamers. Sexes are similar, but the juvenile is a drabber version of the adult. Abyssinian roller is striking in its strong direct flight, with the brilliant blues of the wings contrasting with the brown back and the long tail streamers trailing behind. The call of the Abyssinian roller is a harsh crow-like gak sound, or a screeched aaaargh.

分布与栖息地
The Abyssinian roller is native to tropical Africa. Its range extends from southern Mauritania and Senegal in the west and to Ethiopia, Somalia and northern Kenya in the east. It also occurs in south-western Saudi Arabia and western Yemen. This is a common bird of warm open country with some trees, and has adapted to farmland and human habitation.

行为
Abyssinian rollers often perch prominently on trees, posts or overhead wires, like giant shrikes, whilst watching for the large insects and small rodents on which they feed. They will dash into the smoke of a forest fire for disturbed invertebrates. They are fearless, and will dive and roll at humans and other intruders. The display of this bird is a lapwing-like display, with the twists and turns that give this group its English name. It nests in a scantily lined hole in a tree or building, and lays three to six eggs.

Natal Spurfowl
Pternistis natalensis
A medium-size brownish francolin with distinctive yellow nostrils and a bright orange-red bill and legs. The back is mottled brown, and the underpart feathers are edged brown and white, giving it a marbled scaled appearance. Juveniles are similar to adults, with duller legs and bill. It is common in savanna, preferring thicker understory. The call is a loud raucous “kak-kreek” that variably accelerates and decelerates. Red-billed Francolin differs from Natal Francolin by having barred (not scaled) underparts and a yellow eye-ring. Swainson’s Francolin differs from Natal Francolin by having red facial skin and dark blackish legs.

Yellow-rumped Warbler
Setophaga coronata
One of the most common and widespread warblers; often the core member of mixed warbler flocks during migration, especially early in spring and late in fall. Two main populations: “Audubon’s” breeds mainly in the mountains of the western U.S. and into British Columbia; “Myrtle” breeds from the eastern U.S. across Canada to Alaska. All plumages show a bright yellow rump and yellow on the sides. Most “Audubon’s” have a yellow throat, but dull immature females can be off-white. “Myrtle” Warblers have a white throat that wraps around below the cheek. Both subspecies breed in coniferous or mixed forests, often near clearings or edges. In migration and winter, found in any woodland or open shrubby area, including coastal dunes, fields, parks, and residential areas. Often sallies out from a conspicuous perch to snatch insects. Also eats berries in the winter. Calls frequently: a flat “check” (Myrtle) or rising “chit” (Audubon’s). Another distinctive sedentary population, surely a separate species, occurs very locally in the highlands of Guatemala: Goldman’s Warbler. Males are strikingly black overall, and show a mostly yellow throat with white corners.

Black-billed Mountain-Toucan
Andigena nigrirostris
Distinctive toucan of montane forests in the Andes from Venezuela to extreme northwest Peru. Easy to identify with black cap, dark bill, white throat, powder blue belly, and mostly brownish upperparts. Occurs from 1,500-2,500m, typically below the elevational range of Gray-breasted Mountain-Toucan but occasionally some overlap. Uncommon; usually found singly or in pairs in the forest canopy, often around fruiting trees.
