Bustards
Bustards, including floricans and korhaans, are large, terrestrial birds living mainly in dry grassland areas and on the steppes of the Old World. They range in length from . They make up the family Otididae (, formerly known as Otidae). Bustards are omnivorous and opportunistic, eating leaves, buds, seeds, fruit, small vertebrates, and invertebrates.del Hoyo, J. Elliott, A. & Sargatal, J. (editors). (1996) ''Handbook of the Birds of the World. Volume 3: Hoatzin to Auks''. Lynx Edicions. There are 26 species currently recognised. Description Bustards are all fairly large with the two largest species, the kori bustard (''Ardeotis kori'') and the great bustard (''Otis tarda''), being frequently cited as the world's heaviest flying birds. In both the largest species, large males exceed a weight of , weigh around on average and can attain a total length of . The smallest species is the little brown bustard (''Eupodotis humilis''), which is around long and weighs around on average. ...

Great Bustard
The great bustard (''Otis tarda'') is a bird in the bustard family, the only member of the genus ''Otis''. It breeds in open grasslands and farmland from northern Morocco, South and Central Europe, to temperate Central and East Asia. European populations are mainly resident, but Asian populations migrate farther south in winter. It has been listed as Vulnerable on the IUCN Red List since 1996. Portugal and Spain now have about 60% of the world's population. It became extinct in Great Britain when the last bird was shot in 1832. Recent attempts to reintroduce it into England have met with some success and there is a population of 40 birds on Salisbury Plain, a British Army training area. Here the lack of public access allows them the freedom needed as a large ground-nesting bird. Taxonomy and etymology The genus ''Otis'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. Linnaeus placed four species in the genus but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kori Bustard
The kori bustard (''Ardeotis kori'') is the largest flying bird native to Africa. It is a member of the bustard family, which all belong to the order Otidiformes and are restricted in distribution to the Old World. It is one of the four species (ranging from Africa to India to Australia) in the large-bodied genus ''Ardeotis''. In fact, the male kori bustard may be the heaviest living animal capable of flight. This species, like most bustards, is a ground-dwelling bird and an opportunistic omnivore. Male kori bustards, which can be more than twice as heavy as the female, attempt to breed with as many females as possible and then take no part in the raising of the young. The nest is a shallow hollow in the earth, often disguised by nearby obstructive objects such as trees. Taxonomy English naturalist William John Burchell described the kori bustard in 1822. The specific epithet ''kori'' is derived from the Tswana name for this bird – ''Kgori''. Two subspecies are currently recog ...

Sypheotides
The lesser florican (''Sypheotides indicus''), also known as the likh or ''kharmore'', is the smallest in the bustard family and the only member of the genus ''Sypheotides''. It is endemic to the Indian Subcontinent where it is found in tall grasslands and is best known for the leaping breeding displays made by the males during the monsoon season. The male has a contrasting black and white breeding plumage and distinctive elongated head feathers that extend behind the neck. These bustards are found mainly in northwestern and central India during the summer but are found more widely distributed across India in winter. The species is highly endangered and has been extirpated in some parts of its range such as Pakistan. It is threatened both by hunting and habitat degradation. The only similar species is the Bengal florican (''Houbarobsis bengalensis'') which is larger and lacks the white throat, collar and elongated plumes.

Little Brown Bustard
The little brown bustard (''Eupodotis humilis'') is a species of bird in the family Otididae. Found in Ethiopia and Somalia, its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. As indicated by its name, this bustard is the world's smallest at 45 cm (18 in) and 600 grams (1.3 lb). It is threatened by habitat destruction. Description The smallest species in its genus, the little brown bustard reaches a maximum length of about . They are light brown birds with whitish underparts. The male has a black tuft on the nape, and a black throat speckled with white. The female lacks these black areas, instead having heavy buff spotting on the back, wings and breast. Both male and female have dark flight feathers on the wings, and when flying show a slender white wing-bar, which divides the black feathers from the sandy-brown wing coverts. The female white-bellied bustard (''Eupodotis senegalensis''), which has a wide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omnivorous
An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivores ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
