Chaetops
The rockjumpers are medium-sized insectivorous or omnivorous birds in the genus ''Chaetops'', which constitutes the entire family Chaetopidae. The two species, the Cape rockjumper, ''Chaetops frenatus'', and the Drakensberg rockjumper, ''Chaetops aurantius'', are endemic residents of southern Africa.del Hoyo, J.; Elliot, A. & Christie D.

The Cape rockjumper is a resident of the West Cape and south-west East Cape, and the orange-breasted (or Drakensberg) rockjumper is distributed in the Lesotho Highlands and areas surrounding them in South Africa.

Cape Rockjumper
The Cape rockjumper or rufous rockjumper (''Chaetops frenatus'') is a medium-sized insectivorous passerine bird endemic to the mountain Fynbos of southernmost South Africa. Taxonomy The Cape and Drakensberg rockjumpers were split into separate species in the 1980s. The Latin epithet ''frenatus'' refers to the "bridled" or black-and-white head pattern. When the Drakensberg rockjumper was split it was given the Latin ''aurantius'' meaning 'orange'. Initial taxonomy placed rockjumpers in the thrush family Turdidae in 1867. They were then moved to the babblers Timaliidae in the 1980s, before genetic work in the 1990s placed them in their own family Chaetopidae. See the main page on the rockjumper for more details. Some authorities (notably Dickinson and Christidis) treat the two rockjumpers as a single species, ''Chaetops frenatus'', with two subspecies. However, for most field guides and birders, and according to the International Ornithologists' Union and The Clements Chec ...

Rockfowl
The picathartes, rockfowl, or bald crows are a small genus of two passerine bird species forming the family Picathartidae found in the rain-forests of tropical west and central Africa. They have unfeathered heads, and feed on insects and invertebrates picked from damp rocky areas. Both species are totally non-migratory, being dependent on a specialised rocky jungle habitat. Both species are listed as vulnerable to extinction on the IUCN Red List. Taxonomy and systematics The taxonomic position of the clade and its two species has been confusing. At various times, it has been grouped with the babblers, flycatchers, starlings, crows and others before being placed in a family of its own. Serle in 1952 thought it resembled the Asian genus ''Eupetes'' while Sibley used egg-albumin protein similarity, determined by electrophoresis, to suggest that it belonged to the Timaliidae. Olson revived the idea that it was related to ''Eupetes'' in 1979. A molecular sequence based study sugg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passeri
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as those ...

Avian Incubation
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring. In birds in contrast, the sex of offspring is genetically determined, but in many species a constant and particular temperature is necessary for successful incubation. Especially in poultry, the act of sitting on eggs to incubate them is called brooding. The action or behavioral tendency to sit on a clutch of eggs is also called broodiness, and most egg-laying breeds of poultry have had this behavior selectively bred out of them to increase production. Avian incubation A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monogamy
Monogamy ( ) is a form of dyadic relationship in which an individual has only one partner during their lifetime. Alternately, only one partner at any one time (serial monogamy) — as compared to the various forms of non-monogamy (e.g., polygamy or polyamory). The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. A monogamous relationship can be sexual or emotional, but it's usually both. Many modern relationships are monogamous. Terminology The word '' monogamy'' derives from the Greek μονός, ''monos'' ("alone"), and γάμος, ''gamos'' ("marriage").Cf. "Monogamy" in ''Britannica World Language Dictionary'', R.C. Preble (ed.), Oxford-London 1962, p. 1275:''1. The practice or principle of marrying only once. opp. to digamy now ''rare'' 2.

Rufous
Rufous () is a color that may be described as reddish-brown or brownish-red, as of rust or oxidised iron. The first recorded use of ''rufous'' as a color name in English was in 1782. However, the color is also recorded earlier in 1527 as a diagnostic urine color. The word "rufous" is derived from the Latin ''rufus'', meaning "red", and is used as an adjective in the names of many animals—especially birds—to describe the color of their skin, fur, or plumage.
