Platysteiridae
Platysteiridae is a family of small, stout passerine birds of the African tropics. The family contains the wattle-eyes, batises and shrike-flycatchers. They were previously classed as a subfamily of the Old World flycatchers, Muscicapidae. These insect-eating birds are usually found in open forests or bush. They hunt by flycatching, or by taking prey from the ground like a shrike. The nest is a small, neat cup, placed low in a tree or bush. Distribution and habitat The Platysteiridae are arboreal birds, primarily of the woodlands and forests of sub-Saharan Africa. The family is restricted to mainland Africa and its offshore islands. The shrike-flycatchers and genus ''Dyaphorophyia'' are inhabitants of dense forest, while the rest of the wattle-eyes are found in woodland, and the batises range across all wooded habitats except the densest forests of the Congo Basin. The pririt and pygmy batis survive in very arid environments with some cover, and the white-fronted wattle-eye fav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Batis (bird)
''Batis'' (pronounced BAT-iss) is a genus of passerine birds in the wattle-eye family. Its species are resident in Africa south of the Sahara. They were previously classed as a subfamily of the Old World flycatcher family, Muscicapidae. They are small stout insect-eating birds, usually found in open forests or bush. The nest is a small neat cup low in a tree or bush. They hunt by flycatching, or by taking prey from the ground like a shrike. ''Batis'' species are strikingly patterned, typically with a grey crown, black eye mask, dark back, and paler underparts, often with a coloured or black breast band and white on the throat which contrasts strongly with the black eye stripe. Male and female plumages usually differ. The song is typically a descending triple whistle. Taxonomy The genus ''Batis'' was introduced by the German zoologist Friedrich Boie in 1833. The type species was subsequently designated as the Cape batis. The name of the genus is from the Ancient Greek ''batis'' ...

Pririt Batis
The pririt batis (''Batis pririt'') also known as the pririt puff-back flycatcher or pririt puffback, is a small passerine bird in the wattle-eye family. It is resident in Southern Africa and southwestern Angola. It is a small stout insectivorous, insect-eating bird, found in dry broadleaf woodland and thorn scrubland, scrub.

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15.

Pygmy Batis
The pygmy batis (''Batis perkeo'') is a very small insectivorous bird which finds its food foraging among leaves, it is a member of the wattle-eyes family, the Platysteiridae. It occurs in the dry savannahs of north-eastern Africa. Description The pygmy batis, as its name suggests, is a tiny, rather dumpy but dapper black, white and grey bird with similarities to the flycatchers. The male has a bluish-grey head and back with a contrasting black face mask and short white supercilium above the yellow eye. The rump and lower back are spotted with white and the rump feathers are relatively long giving a fluffy appearance. It has black wings which have a broad white strip formed by the broad white edges to feathers of the median and greater coverts, and the inner secondaries and tertials. The tail is black but the outer tail feathers have white edges and tips. The underparts are white, broken with a narrow black breast band. The females are similar to the males but have a pale rufou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, courtship, and feeding young. The terms ''beak'' and '' rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-like structure), sirens, pufferfish, billfishes, and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections–the upper and lower mandibles–are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexually Dimorphic
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...
