Brown-backed Woodpecker
Dendropicos obsoletus
A small, short-tailed woodpecker with a brown back. Note the white facial streaks that frame a dark cheek. Males have a red back of the cap and females a completely dark cap. Found in a variety of open habitats, including savanna, woodland, scrub, and forest edge. Most similar to Cardinal Woodpecker, but separated by the dark cheek and the plain brown back. Vocalizations include a series of several wailing notes and a quiet rattling.
识别特征
The brown-backed woodpecker is a small species, growing to a length of between 13 and 16 cm (5.1 and 6.3 in). The beak is long and chisel-tipped with a wide base. The male has a red hind crown and nape while the female lacks these. Otherwise the sexes are similar, the head is brown with a white supercilium and moustache and dark ear coverts. The body plumage is brown with white barring on the wings and tail and the underparts are whitish, with variable amounts of dark streaking. When the feathers are worn, this bird looks rather pale and can be confused with the little grey woodpecker (Dendropicos elachus).
分类信息
The brown-backed woodpecker was described by the German naturalist Johann Georg Wagler in 1829 under the binomial name Picus obsoletus. He specified the type locality as Senegambia. The specific epithet is from the Latin obsoletus meaning "plain" or "ordinary". Before the introduction of molecular phylogenetics the relationship to other woodpeckers was uncertain. In 1948 the American ornithologist James Peter placed the brown-backed woodpecker in the genus Dendrocopos in his Check-List of Birds of the World, and in 2013 it was assigned to its own genus Ipophilius by Edward Dickinson and Leslie Christidis in the fourth edition of the Howard and Moore Complete of the Birds of the World. The species is now placed in the genus Dendropicos that was introduced by the French ornithologist Alfred Malherbe in 1849. A genetic study of the African woodpeckers has shown that the brown-backed woodpecker is most closely related to Stierling's woodpecker (Dendropicos stierlingi).<p>Four subspecies are recognised:

分布与栖息地
Its range extends across the entire Sudan region and the southern part of the Sahel, from Guinea Bissau to Eritrea and northern Tanzania. It inhabits open, dry areas, scrubland, the edges of woodland, especially Combretum woodland and Hagenia forest, savannah with scattered trees and suburban gardens. Its altitudinal range is from sea level to about 2,300 m (7,500 ft), and even higher on Mount Kenya.

行为
Breeding occurs between February and June. The nest is excavated in a dead or living tree at height of 1.5 to 6 m (4 ft 11 in to 19 ft 8 in) above the ground. The tree may be at the edge of wood or in an isolated position away from other trees. The clutch of 2 eggs is incubated by both adults. Both adults also feed the young.

Cameroon Olive-Greenbul
Phyllastrephus poensis
An active but easily overlooked long-tailed greenbul found in flocks in the understory and along the edges of montane forest. Can be found near ant swarms. Has a relatively long brownish tail, generally olive underparts, olive-green upperparts, a pale throat, and a gray face. Usually found at higher elevations than other similar greenbuls. Foraging behavior and tendency to move tail and hold it lower than the body are distinctive. Often detected by its harsh chatter, “chuk-chuk-chuk,” or its bubbling “chuk-CHURR-chrchr” song.
Freckle-breasted Thornbird
Phacellodomus striaticollis
Medium-sized ovenbird with a long spiky tail. Cinnamon-brown above, paler below, with a darker cap and wings. Note the freckled breast and yellow eyes. Usually found near water, in marshes, gallery forests, and scrub, where it forages on the ground or in the understory. Builds large thorny nests that do not hang from trees, unlike other thornbirds.
Pied Monarch
Arses kaupi
Small black-and-white flycatcher found in wetter forests of northern Queensland. White underparts except for black breast band, with black mask, tail, and wings, blue eyering, and back back with white band. Rear of head has large puffy white collar (like a space helmet). Compare Frill-necked Monarch, which lacks black breast band and has more black under chin. Forages treecreeper-style, moving up and down tree trunks looking for insects in the bark. Calls include a fast repeated whistle.
