Traditional: ostrich Ostrich: Africa a great shape and will not run faster but bird fly (ostrich), characterized by a long neck without hair, small head, feet have two toes. Is the world's largest birds alive. a rhea. (rhea) Etymology middle english Middle English from old french ostrusce, ostrice From Old French ostrusce, ostrice medieval latin ostrica Medieval Latin ostrica both from vulgar latin * avis str ¿½} Both from Vulgar Latin * avis str ¿½} latin avis [bird] * seeawi- Latin avis [birds] * see awi- late latin str ¿½} [ostrich] * seestruthious Late Latin str ¿½} [ostrich] * see struthious Distributed in Africa and parts of the Arabian Peninsula. Produced in Africa, also known as "African ostrich." Ostrich ostrich (struthio camelus) Ostrich often form a group of 5 to 50 lives, often accompanied with the herbivores. Ostrich with powerful legs (only two toes, the major developed almost toe shoes) to evade the enemy, in shock speed of up to 65 km per hour. If forced to an impasse, kicking opponents. Ostrich mainly plants for food, no water can live a long time. Males competing for females 3 to 5, issue roaring and sizzle. Medieval knight helmet like to use ostrich feathers. Ostrich can be produced soft, fine leather. Ostrich after training for two-wheelers to ride and drive single-seater. Ostrich is not easy to adapt to the conditions of captivity can live 50 years. Ostrich is not a typical flight of birds. Ostrich around in skin color, body size and egg characteristics may differ slightly, before that, this is a different species, is only a subspecies of the ostrich. Ostrich fossils found in southern Russia, India and north-central China, a new strata. Reproduction of the dry season, there are mating struggle, with the male courtship display, females dig shallow pit in sand to nest, each producing 10 to 13 eggs, incubation period of about 42 days, about 3 years of age of sexual maturity, life expectancy about 60 years. Beijing Zoo began breeding in 1954, exhibited in 1985, reproductive success. Endangered species are included in the Convention on International Trade Ostrich ostrich-shaped head families Ostrich-shaped head of the project only Division 1 Division ─ ─ ostrich, ostrich ─ ─ 1 species. Up to 135 kg body weight, body nearly 3 meters. The two wings of degradation, can not fly, limbs stout and powerful enough to only 2 toes (toe 3,4), suitable for running. Sternal non-keel, no tail and tail bone comprehensive sebaceous glands. Male with a mating device. Incubation Sometimes a few female ostrich eggs together, hatching at night when the male and female during the day shifts. Large eggs, a weight of 0.5 to 1 kg. Is generally 40 to 50 ostriches gathered into a group activity. They also used sand and gravel covered the eggs in order to maintain a certain temperature. The end of incubation, some of the birds will nest egg roll to push the edge, is conducive to synchronize hatching. Chicks hatched soon as the birds wander. Ostrich historical records "Rest in peace tribute big bird country. Yan body camel foot, dark green color, give the first seven or eight feet high, wings Zhang Yu Zhang, food barley, their eggs, such as urns, its name ostrich." ─ ─ Guang-Zhi Guo Yigong "Tocharian, offering the first year of Yong Zheng bird, seven feet high, black, footed camels, fluttering the line, day three, to eat iron, vulgar that the ostrich." ─ Chuan Tang Tocharian ─ First, the body and structure Ostrich is today's largest bird kept, mature male (adult cock) 1.75 ~ 2.75 m body height, body weight 60 to 160 kg. Head (head) small, wide and flat, neck (neck) long and flexible, bare head, neck and legs (thighs) were usually pale pink; bill (beak) straight and short, oval-shaped tip of the ; eyes (eyes) Great, inheritance of birds, and their vision is also good, with very thick black eyelashes (eyelashes). Hind legs very thick, only two toes (toes) (Section Ⅲ, Ⅳ toe), and general birds three to four toes is different and the least number of birds who toe, the toe (Ⅲ toe) are larger, with a hard Claw (claw), outside toe claw. Powerful hind legs, except for the sprint, it can also play forward for the attack. Wings (wings) quite large, but can not fly, mainly because of the breastbone (sternum b.) flat, not a keel (keel b.) protruding collarbone (clavicle b.) degradation, and the feathers evenly distributed, no plume area and bare area of the points, fluffy feathers and underdevelopment, lack of differentiation, no small hook Yu branches (barbs), and therefore do not form pinnae, it is clear that the main function is to feather insulation. Male adults are mostly black body, wings and tail end of the end of white feathers, and there was a beautiful wavy; white background with black wings and tail feathers, so that the male is particularly prominent during the day, its wings and feathers color is mainly used to courtship. Females (hens) and males generally similar coat, but not male gray brown fur that 黱 gorgeous. Chicks (chicks) gray mottled brown plumage, molt several times subject to the age of two to reach into the bird plumage. This is mainly to facilitate the camouflage coat. Gender chicks look very much alike, even the young ostrich is also very little difference, so far still can not tell from the appearance of male and female, only to distinguish from the sexual organs. Before the sexual organs in a mature ostrich is very small; male ostrich with a mating device, in the mating season, mature male's testicles (testis) was the size of a fist, but will decline in the non-breeding period, until the next breeding season only and will be enlarged. The pelvis is a closed ostrich-shaped, left and right pubic bone (pubis b.) in the midline to form healing. It should be noted that the ostrich is separate from urination and defecation, which is different from other birds. Eggs large, color like duck eggs, eggs 15 to 20 cm long and weighs 1400 grams, is the largest of those eggs, egg shells very hard, can withstand the weight of a person. Second, the evolution of relations between ostrich Since the bird began to appear since the Jurassic to the Cretaceous have been made to adapt to the majority of the radiation, evolved a variety of waterfowl and land birds to adapt to different environments. Into the new generation, because of the land of the dinosaurs extinction, mammals have not yet developed into a large animal before its ecological status and more replaced by birds, such as North America, Camp Point Eocene birds (diatryma), but not for the huge flightless carnivorous birds, carnivorous animals to fill the vacuum; terror bird (phororhacos) is a large South American Miocene birds of prey, do not fly, but also the lack of South America at the time to fill the vacancy Carnivore. In addition, there are several flightless birds are often classified as "walking birds (ratites)", or special areas in the islands, the lack of mammals to fill the vacancy, well-known examples include the moa in New Zealand ( dinornis), Australia's Ben Bird (dromornis) and Madagascar's elephant birds (aepyornis), which unfortunately appears in human extinction. But there are some of the more fortunate take birds, such as the African ostrich, Australian emu (emu) and cassowary (cassowary), New Zealand kiwi (kiwis), and South America Lai (rheas), thus far survived . These take the most common feature of avian sternum flat, non-protruding keel; However, in the gradual disappearance of the evolution of flight capacity during the flight with the strong chest, and the site of its attachment to become no longer needed. However, whether these take the birds are close blood relations, remains to be enough fossil evidence to explore. Incidentally, the Dodo is also the land birds can not fly, but it is not a close relative of birds to go, but like a dove, so it does not like to go that good running characteristics of poultry. Third, the geographical distribution Ornithologists discovered, according to the characteristics of birds all over, all over the world can be divided into six geographical areas, each district has unique birds, and birds are generally the same area similarity, which is the evolution and adaptation environmental results, which match ostrich distributed in sub-area or Aesop Africa (ethiopian or afrofropical realm). Ostrich widely distributed in Africa's dry areas with low rainfall. Tertiary in the Cenozoic, the ostrich was once widespread in Eurasia, the origin of the famous ─ ─ Zhoukoudian Peking Man discovered not only the ostrich egg fossils, also found a leg bone fossil. Modern has been distributed in Africa, Syria and the Arabian Peninsula, but now on the Syrian and the Arabian Peninsula have been extinct ostrich; their distribution is south of the Sahara desert has been the whole of Africa, and Australia in year 1862 ~ 1869 introduction, in the southeast to form a new habitat. Fourth, classification Ostrich (ostrich) as the ostrich-shaped head (struthioniformes), collectively, are now birds subclass (neornithes) in the flat chest Head (ratitae, also known as the ancient jaw Head (palaeognathae)); flat chest Head in addition to ostrich-shaped head of the , there are American Ostrich Head (or Lai Head (rheiformes)), the Australian ostrich head (or fresh turkey head (casuariiformes)) and the kiwi project (apterygiformes), belong to no flying ability of birds. Due to geographic isolation and the formation of ostrich six strains could be differentiated: sc camelus, North African ostrich (north africa ostrich), the largest number of extant species, the first to be found in North Africa south of the Sahara, but has been extinct in the country of origin, their habitat and the numbers are decreasing. The male has a bare head and crown cover, for the North African ostrich and Marseille species (sc massaicus) the greatest distinction. sc spatzi, stresemann, in 1926 in rio de oro is described in this book, it is based on the classification of small and special in its egg shell structure, it may now be extinct. sc syriacus, Arabian ostrich (arabian ostrich), rothschild, located in Syria and Arabian desert, is the most northern distribution of ostrich. This species was the largest number of species, but has been extinct in AD 1941. sc molybdophanes, blue neck ostriches, Somali ostrich (somali ostrich), reichenow, located in located in the Tanner Creek (the tana river) of somaliland and gallaland. Bare head, neck and legs were bluish gray, silver-gray hair covering the neck, the base of the neck feathers are white, the back was black, with a brilliant reddish; beak dark red, the top yellow; head for the dark yellow solid plate structure; front leg was dark red or orange-red, close to the toe was yellow. sc massaicus, Masai ostrich (masai ostrich), neumann, located in Kenya (kenya) and Tanganyika (tanganyika) east. Adult male African ostrich (sc camelus) were similar, but non-exposed male bonnet; this is different from other varieties with Somali species is characterized by deep purple egg with a tiny hole. sc australia, the South African ostrich (south africa ostrich), gurney, distributed in South Africa cunene river and zambesi river south. Bare head, neck and legs were leaden, with hair covered, not with a naked male bonnet; beak gray and black, upper edge of the base and dark red, the color change the breeding season is bright; calf is dark gray the breeding season turned dark red. It is said that in Angola (angola) and can still be found in the northern part of South West Africa. Five living habits Ostrich is to take the birds to adapt to life in the desert wilderness, good running, running speed of about 60 km per hour can be maintained for about 30 minutes without feeling tired; step up to 7 meters, and can change direction instantly, when running in a rapidly wings open, for balance. In order to capture those rare and scattered in the desert, the food, the ostrich is a very efficient intake who, thanks to their step valve open long, flexible neck and accurate pecking; ostrich source of nutrition is Canton, food plants, leaves, flowers, fruits and seeds, also eat small animals, are omnivorous. Ostrich peck, the first top of the food gathered in the esophagus to form a food ball, and then slowly through the cervical esophagus to swallow. When the ostrich pecking the head must be low, it is vulnerable to predators, so the food may look up and look around from time to time. Ostrich usually three to five groups, with as many as habitat for more than twenty only. Often with the antelope (antelope), zebra (zebra) in the same area infested with these animals by using ostrich keen eye for the warning effect. Male ostrich will be divided into spheres of influence in the breeding season, when the approach of other males will use their wings to the expulsion and shouting their cry loud and deep. The breeding period of time with a different region, in North Africa and East Africa are mostly in the dry season (July to next January) nest, the male in the territory of the friction out of many small shallow pit, the ostrich is a male during the breeding period, more than female, but male ostrich and one of them (the "major" hen) to maintain a single loose pairing (pair bond), the female will find one hole to lay eggs, usually one every two Nissan, a total number of days can lay up to 10 ~ 20; about six or more only the female (the "minor" hens) lay eggs at the same point, but is not responsible for incubating, nest eggs varies from 30 to as many as Marseille species (masai race) 50 ~ 60 pieces. Male overnight incubation, by the female during the day as. Incubation temperature is about 96.8 ~ 97.6. f. There are many predators on the desert like stealing an ostrich egg, so no adult birds guarding their nests are vulnerable to natural enemies of patronage, such as the Egyptian vulture (egyptian vulture) would throw stones to break eggs to the egg shell thickness 2mm ; even the successful birds guard the eggs, some coyotes (hyena), jackal (jackal) and other natural enemies, so in the three-week spawning period and incubation period of about six weeks less than 10% of the eggs hatched. Chicks as early as birds (precocial bird), bringing together the female and male adults, the number of nests often form a large group of chicks from one to two adults escort, but only about 15% of which can be up to one year old, this when they have grown into adults height. Females reach sexual maturity two years, the male later, about three to four years, life expectancy of about 30 to 40 years. Ostrich egg high nutrition, hectogram containing 22.54 grams protein, 80 mg calcium, 4.03 mg of iron.
