Cape Batis
Batis capensis
A cute, dumpy, colorful flycatcher-like bird that flits around in the mid-canopy and understory of forest, forest edge, thickets, and gardens. There is a chestnut stripe across the top of the closed wing of both sexes. Males have a broad black chest band, yellow eye, and white throat. Females have a reddish eye and brown chin patch. The song is a series of 8-9 plaintive steady piping “peooop” notes, and calls include buzzing grating “ddrz-drrzt-drrr, ddt-ddzt-drzt-drr”. Distinguished from other batises in its range by the chestnut stripe through the wings.
识别特征
The Cape batis is strikingly patterned. The adult male has a grey crown, black eye mask and white throat. Its back is brown, with a black rump and tail and rufous wings. The underparts are white with a broad black breast band and rufous flanks. The female and juvenile plumages differ in that the breast band is narrower and rufous, not black, and there is a small rufous patch on the throat. Their rufous wings and flanks distinguish them from other Batis species in the region.<p>The males of the two Malawian subspecies (B. c. dimorpha and B. c. sola) differ in having colder tones to the upper part and flank plumages (lacking any rufous or olive), besides having shorter bills, and are sometimes separated as the Malawi batis (Batis dimorpha). The population of Mount Namuli may represent a third subspecies of this northerly taxon.<p>The song is typically a triple whistle cherra-warra-warra or foo-foo-foo.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Cape batis in his Ornithologie based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name Le gobe-mouche du Cap de Bonne Espérance and the Latin Muscicapa Bonae Spei. 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. One of these was the Cape batis. Linnaeus included a brief description, coined the binomial name Muscicapa capensis and cited Brisson's work. The specific name capensis denotes the Cape of Good Hope. The species is now placed in the genus Batis that was introduced by the German zoologist Friedrich Boie in 1833.<p>Five subspecies are recognised.

行为
Both the male and the female will aggressively defend their territory. When larger birds of prey, animals or humans approach, the bird will often perch conspicuously near the intruder and angrily protest audibly. The Cape batis hunts by flycatching, or by taking prey from the ground like a shrike. The nest is a small neat cup low in a tree or bush.

其他鸟类
Long-legged Buzzard
Buteo rufinus
A large, long-winged buzzard which may recall a small eagle in size. Variable plumage with three color morphs. All have obvious dark carpal patches at the wrist of the wing. Juveniles lack the adult’s prominent black trailing edge to the wings. Often hunts from a prominent perch, or sits on the ground and scans for prey. A species of open steppe and desert country, sometimes in more wooded areas but always near big open spaces. Compare with similar Common and Upland Buzzards, as well as Rough-legged Hawk; note long-winged structure, size, and wings held in “V” in soaring flight.
Unicolored Antwren
Myrmotherula unicolor
Uncommon small, short-tailed antwren of the lower and middle levels of humid forests. Very active and often follows mixed-species flocks. Males are uniform gray with a small dark throat patch, while females are uniformly brown-gray, with less gray in the head than female Salvadori’s Antwrens.
Black-legged Seriema
Chunga burmeisteri
Tall terrestrial predator of the Chaco region. Plumage distinctively shaggy. Prefers dense, spiny vegetation, often with thick undergrowth, but can occur in nearby open areas. Smaller and shyer than Red-legged Seriema. Despite its large size, can be difficult to see, and is more often detected by its loud, far-carrying song.
