Burchell's Sandgrouse
Burchell's sandgrouse (''Pterocles burchelli'') is a species of bird in the family Pteroclidae. It is found in arid and semi-arid regions of southern Africa. The name of this bird commemorates the English naturalist William John Burchell. Description Burchell's sandgrouse is a plump bird about the size of a pigeon with a small head and short legs. The body is light brown, mottled with darker shades and white speckles. In males, the eye is surrounded by bare yellow skin and the cheeks and throat are pale grey. The male grows to about long and the female is a little smaller. Distribution and habitat Burchell's sandgrouse is found in Angola, Namibia, Botswana, Zambia, Zimbabwe and South Africa. It is normally resident but moves about to a limited extent depending on the availability of water and the seeds it mainly eats. It is widespread and common in much of its range.BirdLife International 2004''Pterocles burchelli'' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Southern Africa
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 swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterocles
''Pterocles '' is a genus of near passerine birds in the sandgrouse family. It includes all the species in the family except for two central Asian species in '' Syrrhaptes'' These sandgrouse have small, pigeon-like heads and necks, but sturdy compact bodies. They have long pointed wings and sometimes tails. Their legs are feathered down to the toes, but unlike species of the genus ''Syrrhaptes'' the toes are not feathered. ''Pterocles'' species have a fast direct flight, and flocks fly to watering holes at dawn and dusk. Two to three eggs are laid directly on the ground. They are buff or greenish with cryptic markings. All species are resident. Taxonomy The genus ''Pterocles'' was introduced in 1815 by the Dutch zoologist Coenraad Jacob Temminck. The type species was subsequently designated by the English zoologist George Robert Gray as the pin-tailed sandgrouse. The genus name combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precocial
In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. Precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. Precocial species are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. These categories form a continuum, without distinct gaps between them. Altriciality Etymology The word is derived from the Latin root ''alere'', meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called ''precocial''. Precociality Etymology The word "precocial" is derived from the same root as ''precocious'', implying early maturity in both cases. Superprecociality Extremely precocial species are called "superprecocial". Examples are the megapode birds, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Datura Innoxia
''Datura innoxia'' (often spelled ''inoxia''), known as pricklyburr, recurved thorn-apple, downy thorn-apple, Indian-apple, lovache, moonflower, nacazcul, toloatzin, toloaxihuitl, tolguache or toloache, is a species of flowering plant in the family Solanaceae. It is more rarely called sacred datura, a common name which is applied more often to the closely related ''Datura wrightii''. It is native to the Southwestern United States, Central and South America, and introduced in Africa, Asia, Australia and Europe. The scientific name is often cited as ''D. innoxia''. When English botanist Philip Miller first described the species in 1768, he misspelled the Latin word ''innoxia'' (inoffensive) when naming it ''D. inoxia''. The name ''Datura meteloides'' was for some time erroneously applied to some members of the species, but that name has now been abandoned. Description ''Datura innoxia'' is a tuberous-rooted subshrub that typically reaches a height of 0.6 to 1.5 metres. Its stems a ...

Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'' and ''galingales''. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including ''Chedra microstigma''. They also provide an alternative food source for ...

Tephrosia
''Tephrosia'' is a genus of flowering plants in the pea family, Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions. The generic name is derived from the Greek word τεφρος (''tephros''), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense trichomes. Hoarypea is a common name for plants in this genus, along with Goat's Rue and Devil's Shoestring. Uses Many species in the genus are poisonous, particularly to fish, for their high concentration of rotenone. The black seeds of ''Tephrosia'' species have historically been used by indigenous cultures as fish toxins.NTFlora Northern Territory Flora online:''Flora of the Darwin Region: Fabaceae.''Retrieved 10 June 2018 In the last century, several ''Tephrosia'' species have been studied in connection with the use of rotenone as an insecticide and pesticide.

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
