Monteiro's Bushshrike
Malaconotus monteiri
A large, robust bushshrike with a massive head, a chunky hook-tipped bill, and a gray eye and head; a white patch on the face often extends above and below the eye. Wings are green, spotted with yellow. Pairs skulk at middle levels and in the canopy of montane and gallery forest and plantation edges, seldom joining flocks. The species forages slowly and deliberately, hopping along branches, diligently searching for food. Gray-headed Bushshrike, which prefers savanna, differs from the larger Monteiro’s by having pale yellow eyes and a white facial patch that is restricted to the area between the eye and bill base. Monteiro’s gives a low-pitched extended sorrowful “whhooooooo” song repeatedly, along with various harsh clicks and rasps.
分类信息
Two described subspecies: nominate Malaconotus m. monteiri (Shape, 1870) described from Angola, and M. m. perspicillatus (Reichenow, 1894) known from only a single specimen in Cameroon. Subspecies perspicillatus differs from the nominate in having a larger bill and paler undersides.<p>Presumed to be closely related to other Malaconotus, and has been considered conspecific with both gray-headed bushshrike M. blanchoti and fiery-breasted bushshrike M. cruentus in the past. Cameroonian M. m. perspicillatus has also been theorized to be a color morph of the green-breasted bushshrike. The specific phylogenetic relationships of M. monteiri are, as of yet, unknown.

分布与栖息地
It is found in Angola and Cameroon, with a historical record from the Albertine Rift of eastern Democratic Republic of the Congo and a lost specimen from Kakamega Forest, Kenya.<p>This species' habitat is subtropical or tropical moist montane forests. In Angola, the nominate subspecies is found primarily along the Angolan Escarpment, with a distribution mirroring that of other Angolan endemic taxa.<p>This species is largely unknown outside of Angola. Cameroonian birds are described as the subspecies Malaconotus monteiri perspicillatus based on a single specimen from Mt. Cameroon in 1894. The subspecies of records in the Democratic Republic of the Congo and Kenya has not been confirmed, though the Congolese record has tentatively assigned to perspicillatus in the past. There are scattered sightings of reported individuals in other mountain ranges in western Cameroon (namely, Mt. Kupé and the nearby Bakossi Mountains), though these records are usually considered unconfirmed.<p>It is probably threatened by habitat loss like other birds in its range, but its actual status remains unknown due to its elusiveness.

Nullarbor Quail-thrush
Cinclosoma alisteri
Heavily patterned terrestrial bird of Nullarbor Plain. Both sexes have pale eyebrow, brown back, and black-and-white markings on wing. Female has buff chin and moustache, white belly, and pale gray chest, male a white moustache, black throat patch that connects to thick black breast band (forming an upside-down "T"), and brown sides. Note that male Copperback Quail-thrush has black chest. Usually seen walking around in very open low shrubland. Calls include a long, high-pitched whistled "seeeep."
Laggar Falcon
Falco jugger
A large, slender falcon with long wings that nearly reach its tail tip when perched. It has a rusty crown above a thin white brow that can connect to its pale forecrown, above a bold dark eye-stripe that extends to the nape. The moustachial stripe sometimes seems to have a break at the gape line. Upperparts mostly brown; white underparts can be streaked at the breast and solid brown at the thighs. A species of open, arid country that preys mainly on birds.
Gray-backed Sparrow-Lark
Eremopterix verticalis
A small, compact finch-like sociable lark that is both resident and nomadic, although movements are poorly understood. The sexes differ in plumage: the male has a gray-brown back and wings with a scalloped pattern, and a black head with bold white ear patches that reach the back of the neck; the streaky female is variable depending on geographic range, but always has a dark belly patch and tends to be paler than other female sparrow-larks. Flocks of 20 to 100 birds (often mixed with other sparrow-larks or with Stark’s Lark) can appear in grassy patches in semi-arid shrublands and fallow fields. They shuffle along in bare patches foraging for seeds and insects.
