Wildebeest

The ungainly gnu earned the Afrikaans name wildebeest, or ''wild beast," for the menacing appearance presented by it's large head, shaggy mane, pointed beard, and sharp curved horns. In fact, the wildebeest is better described as a reliable source of food for the truly menacing predators of the African savanna: lions, cheetahs, wild dogs, and hyenas.
Here's a fast fact about this magnificent animal:

                                                           Type: Mammal
                                                           Diet: herbivore
           Average life span in the wild: 20 years
           Size: up to 4.5 ft (1.4 m)
           Weight: 330-550 lbs (150-250 kg)
           Group name: herd
           Size relative to a 6-ft man (2 m) man:

 The gnu (pronounced "g-new" or simply "new") is a member of the antelope family, although it's heavy build and disproportionately large forequarters make it look more bovine. Gnus can reach 8 feet (2.4 m) in length, stand 4.5 feet (1.4 m) tall at the shoulders and weight up to 600 pounds (272 kilograms). Both male and female wildebeest grow horns.

 Their habitat comprises the grassy plains and open woodlands of central, southern, and eastern Africa, particularly the Serengeti in Tanzania and Kenya. They travel in large herds and are active day and night, grazing constantly. Pretty cool, eh?


Their spectacular northward migration in search for greener pastures is dictated by weather patterns, but usually takes place in May or June. It is considered one of the greatest wildlife spectacles on earth, involving up to 1.5 million wildebeest as well as hundreds of thousands of other animals, including zebras and gazelle.

 Up to 500.000 calves are born in February and March each year, at the beginning of the rainy season. Calves learn to walk within minutes of birth and within days are able to keep up with the herd. Gnus can live to be 20 years old. That's all for today folks, hope you enjoy reading my blog. GBU you all.

Our Earth.

Hi, and welcome to my posts about our earth. Several years ago I  learn about our amazing, beautiful world. And I am gonna tell you guys about what I learn. Our home is a wonderful world created by God for us to live in it. Let's first learn about the outer appearance of our earth. Way out there in outer space our earth looks like a large sphere (ball). It has vast swarms of white clouds, blue oceans and green land area. At the top of our earth is the North Pole while at the bottom lies the South Pole. Both the poles are covered with ice caps that appeared white. Our earth viewed from space is truly beautiful.
Let's consider about some details about the overall structure of the earth.
                   Size and Shape.
Our earth is shaped like a sphere. However.... our earth is not completely round. It is slightly flattened at the poles. This means that the diameter of the earth measured from the North Pole to the South Pole is slightly less then the diameter across the middle of the earth, at the equator. From pole to pole the diameter of the earth is about 7,900 miles ( 12,714 kilometers ). At the equator, the diameter of the earth is about 7,926 miles ( 12,756 kilometers ). Therefore, the distance from pole to pole is 26 miles ( 42 kilometers ) less than the diameter of the earth at the equator. That's why it's slightly flattened at the poles although it may look perfectly round from far away in space. In the same way the distance around the earth is shorter at the poles than at the equator. At the poles, the earth is 24,860 miles ( 40,008 kilometers ) around. At the equator, it is slightly greater : 24,902 miles ( 40,075 kilometers ) around. However, the equator is not actually the "fattest" part of the earth. The distance around the earth is greatest along a circle slightly south of the equator. Therefore, the earth's shape is a little like a pear, which had it's fattest just bellow it's middle. But this bulge in the earth's shape is so small that the earth still looks like a perfectly round sphere when viewed from space.                                                                            
                                                                             Layers of The Earth
You might think of layers as layers of a cake, but that isn't what I meant. The earth really does have layers, like a cake. The layers name are, from the top to the bottom, Crust, Mantle, Outer Core, Inner Core.
CRUST : The crust is the outer layers of our beautiful earth. It contains all life on earth because life isn't sustainable below the crust.
MANTLE : The mantle is the thickest part of all the layers of the earth. The mantle is made up of two parts. The upper part is name asthenosphere and is 200 km ( 200 mi ) thick, and the lower part is name lithosphere composed of rigid rock about 50 - 120 km ( 31 -  75 mi ) thick.
OUTER CORE : Our earth's outer core is made up of liquid layer about 2.266 km ( 1.408 mi ) thick. It is made of nickel and iron. The temperature of the outer core is estimated about 4.300 K ( 4.030 C; 7.280 F ).
INNER CORE : The earth's inner core is the hottest, innermost part of our earth. It is primarily a solid rock with a radius about 1.220 km ( 760 mi ) according to seismological studies. It is believed to be on an iron-nickel alloy and to be approximately about the same temperature as the surface of the sun : approximately 5.700 K ( 5.430 C ).

Stork

Stork are large birds with long leg, long neck, long stout bills. There are many kinds of stork like Marabou stork, wooly-necked stork, painted stork and many others. All together there are 19 species of stork in six genera. Stork live in many regions of the world, tending to live in drier habitats than other birds like herons, spoonbills, and ibises. Many of the species of stork are migratory. Most of the stork species eat frogs, earthworms, insects, fish, small birds, and small mammals. If you want to know stork's scientific classification  well here it is:
     
                         Kingdom:     Animalia
                         Phylum:       Chordata
                         Class:          Aves
                                                                Subclass:     Neornithes  
                                                                Infraclass:    Neognathae
                                                                Superorder: Neoaves
                                                                Order:         Ciconiiformes
                                                                Family:        Ciconiidae


When they fly they tend to use soaring, gliding technique, which of course conserves energy. Their nests are often very large and old. Some stork's nest have been found to be 2 m ( 6 feet ) in diameter and about 3 m (10 feet) in depth. When they had build a nest they stick to each other like partners.

Peregrine Falcon

Hi guys, Sorry I have not post for a long time, I kinda forget. Well anyways today I am gonna post about the peregrine falcon, the fastest bird in the world. And here it's :

   The peregrine falcon or you could just called it peregrine was one called the duck hawk in North America is a widespread bird of prey from the family falconidae. And here is his appearence: Large crow-sized falcon with a blue-gray back, barred white underparts, black head and a moustache. As is typical of bird-eating raptors, peregrine falcons are sexually dimorphic which means that the females are bigger than males. Peregrine are renowned for its speed, reaching over 322 km/h which is about 200 mph during its style hunting which is the hunting stoop in which peregrine dive down in very high speed making it the fastest member of the animal kingdom. According to a National Geographic program, the highest measured speed of a Peregrine Falcon is 242 mph about 389 km/h.
 Peregrine falcon's breeding range includes land region from the arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains and most tropical rainforest; the only major ice free land mass from which it is entirely absent is New Zealand. This makes it the world's most widespread raptor and one of the widely found bird species. Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern population.
 While its diet consists almost exclusively of medium-sized bird, the peregrine will occasionally hunt small mammals, small reptile or even insects. Reaching sexual maturity at one year, it mates for life and nests in a scrape, normally on cliff edges or, in recent times, on tall human made structures. The Peregrine Falcon became an endangered species in many areas because of pesticides especially DDT. Since the ban on DDT from the early 1970's, populations have recovered, supported by large-scale protection of nesting places and releases to the wild.
