This bird has a long neck, powerful legs soft plumage, bare skin on head, neck, and thighs. Male is black with white wing primaries; the tail varies from whitish to gray or cinnamon brown; skin on its head and neck, pink or blue flushing bright red during courtship; brown eyes with large eyelashes. Female is pale brown with pinkish neck and head; wing tips sometimes can be white.

This bird breeds at different times and it varies with latitude. The male makes a number of unlined scrapes on the ground. The female selects one and lays up to 12 yellowish-white eggs, then several other females lay more eggs in the same scrape. The nest can contain up to 40 eggs; they are incubated by the male at night, and by the dominant female by day, for about 42 days. This arrangement where the dominant females help to take care of the eggs is almost unigue. Maybe her own eggs benefit from being part of a larger group. There are so many eggs she will kick out those eggs who are not hers. Exactly how she tells which eggs are her own is not clear. The ostrich egg is the largest of any bird on earth, measuring up to 8 inches (20cm) long.

The biggest and heaviest of all living birds, the ostrich is widely distributed throughout the drier parts of Africa.

It is ideally adapted for life on arid grasslands, where its long legs allow it to gather food from wide ranges. It can lose up to a quarter of its body weight through dehydration, which gives it a big advantage in desert regions where sources of water are few and far between. The ostrich cannot fly, but makes up for this with its powerful legs that allow it to out run most of its enemies.
Ostriches can reach running speeds of up to 45 mph (70km/h). It also can walk forever without getting tired.

Ostriches will form flocks of 10-50 birds and search for food. The large males will defend their territories with a loud, deep call that resembles the roars of lions, and it will inflate the red-flushed skin of their necks in display.


 Not:1  Ostriches cannot fly, but don't feel too sorry for them. The ostrich is the fastest bipedal runner in the world, capable of reaching speeds up to 45 miles per hour--about twice what the fastest human can achieve. What's more, an ostrich can maintain this speed for up to half an hour


Not: 2 Male ostriches are polygamous, but they tend the nest with a single favored mate. This hen lays about a half-dozen eggs in a shallow depression in the sand, which takes her about two weeks. Other hens then add their own eggs to the nest, and once they are finished, the favored mate chases them off. The nest owners then incubate all the eggs: The female sits on them during the day, and the male takes a turn at night.


NOT: 3 Although the ostrich egg is the largest of all eggs, it is the smallest egg in relation to the size of the bird. A three-pound egg is only about 1 percent as heavy as the ostrich hen; by contrast, a kiwi's egg--the largest in comparison to the mother--is 15 to 20 percent of the mother bird's mass. An ostrich egg is equivalent in volume to two dozen chicken eggs.


NOT:4 The ostrich is the largest living bird in the world. An ostrich chick grows one foot taller each month until it is seven or eight months old. Adult ostrich roosters are six to ten feet in height and can weigh as much as 340 pounds. Because of their prodigious size, ostriches were occasionally used for riding or pulling chariots in ancient Egypt; the practice never really took off, because the ostrich has a nasty tempe.



Not: 5  This great bird has only two toes; all other birds have three or four. Ostriches kick forward, not backward, because that's the direction in which their knees bend. Ostriches never need to drink water some of it they make internally, and the rest is derived from the vegetation they eat.

    Physical Attributes

      A male ostrich stands between 6 and 9 feet at maturity, while
      females will range between 5 [1/2] to 6 [1/2] feet tall at
      maturity. Ostrich chicks grow about 10 inches per month for the
      first year and weigh about 100 pounds at 12 months of age.
      Domesticated ostriches reach maturity at 2-to-3 years of age.
      Females mature about 6 months earlier than the males.  Ostriches
      normally live from 30-to-70 years in captivity.

      Even though ostriches are flightless birds, their wings are
      surprisingly strong. Ostriches use their wings for aggressive
      display and courtship rituals. Males have contrasting bright white
      and black plumage. The female's plumage is grey and drab. Their
      lead-blue skin color usually becomes scarlet over the beak, on the
      forehead, and around the eyes during the mating season. The normal
      body temperature range of the ostrich is between 103 and 104 F.
      During hot weather, ostriches lift and fan their wings, while
      during cold weather they cover their thighs with their wings. The
      ostrich is the only bird to have only 2 toes on each foot. Emus,
      rheas and cassowarys, which are also classified as ratites
      (flightless birds), have three toes on each foot. Ostriches are
      fast runners, and their first instinct upon being frightened is to
      run. Ostriches can cover between 16-to-23 feet per stride and
      maintain speeds between 30 and 50 miles per hour for 30 minutes.



      Breeding

      The breeding season for ostriches begins in March and April and can
      last until September. Breeding season length largely depends on
      food availability, bird condition, and weather. Approximately two
      months prior to the beginning of the breeding season birds should
      be separated into breeding pairs. Groups of one male and two female
      birds can also be penned together. Bird condition is important as
      unhealthy and improperly conditioned birds will often be less
      productive egg layers.

      Courtship of ostriches involves elaborate displays by both sexes.
      Shortly after mating, the female will lay between 12-to-15 eggs.
      Generally, females will lay an egg every other day. If the eggs are
      taken from the nest daily, the hen may lay up to 80 eggs, although
      40-to-50 is more typical. An inadequate diet may result in less egg
      production. Ostrich eggs are the largest of all eggs and weigh
      about 2.75 pounds. The contents of one ostrich egg is equivalent to
      two dozen chicken eggs.



      Breeding Paddock

      Ostriches prefer larger paddocks; however, oversized paddocks can
      cause birds to become more wild, skittish and harder to control. A
      good paddock size for a breeding pair is 1-to-3 acres. Planting the
      paddock to alfalfa will allow the birds to have quality forage for
      grazing. A few trees or shrubs for shade and privacy are advised.
      The paddock should be enclosed with 5-foot high wire fence. There
      should be a double fence between two paddocks, with at least 6 feet
      between fences, to prevent males from injuring themselves fighting.
      Four-to-five strands of 8 gauge smooth wire is sufficient with
      posts spaced 10 feet apart. Never use barbed wire as birds will
      inevitably do serious harm to themselves. A hedge or windbreak is
      also good between pens to provide more privacy during courtship
      displays. The pen should have an area about 25 square feet by 6
      inches deep of clean sand for the birds to roll in.

      Ostriches are hardy birds; however, they do require protection from
      snow, ice, extreme wind, cold rain, and sleet. Paddocks should be
      designed so birds have to access a shelter (confinement pen) to
      obtain feed and water. Pens designed in this manner simplify the
      task of catching and restraining the birds. Also, having feed and
      water in the shelter protects it from the elements. Feeders and
      waterers should be positioned so that managers can access them
      without exposing themselves to overly aggressive ostriches. While
      not prone to aggressive behavior, ostriches may become more
      aggressive during the breeding season.

      Feeders should be open-type measuring about 48 inches long by 14
      inches wide and 4-to-6 inches deep. Feeders should be partitioned
      into equal sections: one containing a ratite breeder ration, one
      containing shelled corn, and one containing oyster shell. A one day
      supply of breeder ration and shelled corn should be placed in the
      feed box. The water pan should be 24-to-30 inches wide and 5-to-8
      inches deep. Ostriches drink by scooping water with their beak.
      Therefore, they need a depth of water sufficient to immerse their
      beak and a long enough distance to move across to adequately drink.
      Feeders and waterers should be mounted at the bird's chest height.



      Incubation

      There are two main methods of incubation for domestic ostrich
      production, natural and artificial. Many African ostrich producers
      prefer natural incubation because they feel chicks hatched with
      artificial incubation are not as healthy. This is probably true,
      since under natural conditions only the strongest chicks survive;
      however, fewer chicks survive under natural incubation. Also,
      allowing ostriches to sit on eggs for up to six weeks can cause
      strain on the birds and deteriorate their condition. Both male and
      female ostriches share sitting responsibilities, usually the male
      at night and the female during the day.

      If the hen is allowed to sit on the eggs, she will normally lay
      about one egg every other day for a total of 12 to 15 eggs. The
      nest will generally be a shallow depression in the ground. It is
      possible to enhance the nest by digging a small hole next to the
      nest, filling it with coarse sand, and building a small bank around
      it.

      Producers in the United States usually practice artificial
      incubation. United State's producers generally feel there is too
      much investment in the birds and eggs for natural incubation.
      Greater egg production should result if eggs are removed from the
      nest each day. If artificial incubation is used, eggs should be
      gathered twice daily, stored with large ends up or on their sides,
      cooled to 65 to 70 F, and placed in the incubator within 2-to-4
      days. If eggs are not incubated within 4 days, hatchability usually
      declines. Eggs should be turned 3 times daily prior to being placed
      in an incubator.

      Only clean, sound eggs should be incubated. Dirt and manure should
      be gently scraped off or removed with sandpaper. Eggs should not be
      wiped with a cloth as this could force bacteria deeper into the
      pores of the egg shell, increasing chances of infection. If eggs
      must be washed, use water containing a sanitizing agent, with water
      temperature maintained 10 F warmer than the eggs. Sanitizing agents
      suitable for use on ostrich eggs include ammonium compounds or
      compounds containing chlorine, iodine or synthetic phenol. Water
      should be changed frequently to prevent spreading of bacteria.
      Improper cleaning is worse than no cleaning at all. Latex gloves
      should be worn when handling eggs to prevent oil on skin from
      penetrating the shell.

      Good quality incubators and hatchers are necessary. Other than
      birds themselves, incubators and hatchers should represent the
      greatest monetary investment. Several companies manufacture ostrich
      incubators and hatchers. Some of the companies are listed:
      Humidaire Incubator Co., New Madison, OH (513/996-3001); Kuhl
      Corporation, Flemington, NJ (201/782-5695); and G.Q.F. Mfg. Co.,
      Box 1552, Dept. OST, Savannah, GA 31498 (192/236-0651).

      Ostrich eggs need to be incubated for 42 days. Unless otherwise
      specified by the manufacturer, the eggs should be incubated at 97.5
      to 98.5 F. Relative humidity should be kept at 35 to 40 percent
      through day 40 (beginning of pipping), after day 40, humidity
      should be kept at 83 to 88 percent.

      Fertile eggs should begin to hatch on the 42nd day. Chicks will
      usually hatch without assistance within 12 hours after they first
      pip (break) the shell. Chicks should not be removed prematurely as
      blood vessels may break, or if not given sufficient time to
      struggle, the yolk sac may not be drawn into the chick's body. If
      a chick has not hatched after 20-to-30 hours and appears weak,
      carefully remove a few pieces of shell. Be sure to remove pieces of
      shell which are cutting the chick's bill.

      After the chicks have hatched, let them dry for 3-to-4 hours in the
      brooder (90 to 95F). After the chicks have dried sufficiently,
      place no more than 3 birds in a 4 foot by 5 foot pen.


    

Green Lizard




In 1991,scientists divided the former one species of green lizards into two, a Western Green Lizard (Lacerta bilineata) and an Eastern Green Lizad (Lacerta viridis). There are however only very slight morphological differences and it could well bet hat further studies might show that they indeed are only one species and revert their nomenclature again to the previous situation. As all lizards (and geckos) also the green lizard can actively lose its tail in dangerous situations, i.e. when threatened by a predator like a marten, a weasel a bird of prey or a house cat. This is called “autotomy”. Beginning with the sixth, each tail-vertebra of the green lizard has a pre-prepared site of fracture. By a strong and sudden contraction of the circular tail musculature it can separate itself from a bigger or a smaller portion of the tail as need arises. Due to the still functioning autonomous nervous system of the tail fragment the detached body part does still move vigurously up to twenty minutes, thus catching the attention of the persecutor and allow the now tailless lizard to get away. Thus by sacrificing a non vital body part, in most cases the lizard succeeds in saving its life. After a while the lizard grows a new tail, however this substitute is not supported by another vertebral column but by a cartilaginous and unbreakable rod. 
The European green lizardLacerta viridis, is a large lizard distributed across European midlatitudes from Slovenia and eastern Austria to as far east as the Black Sea coasts of Ukraine and Turkey. It is often seen sunning on rocks or lawns, or sheltering amongst bushes.             
Ecology and life cycle
It feeds on insects, small lizards and even mice. In spring, the female lays six to 20 eggs. About two to three months later, brown-colored young appear, with a length of 3–4 cm (1.2–1.6 in).

Facts about this animal                            With a total length of 25 to 35 cm (up to even 42 cm), whereby the tail measures 2/3 of the total length, the Lacerta viridis belongs to the “giants” among the lizards of the family Lacerdidae. The body of the males is a brilliant emerald green (hence its German name) punctuated with small yellow and black spots that are more pronounced upon its back. The throat is clear blue in the adult males in particular during the mating season. The colour of the females is more variable and young animals are rather brown. The belly of the males is yellow, that of the females pale yellow to greenish. Around mid March the first males leave their winter quarters and expose themselves to the sunlight. About two weeks later the females follow. The green lizard is active at daytime with a peak of activity in the morning. Usually it stays on the ground, but in cooler wather this thermophile reptile may also climb on low branches for basking. After sunset it can be found on stillwarm stones or rocks. The preferred temperature lies between 32 to 33 °C But it can tolerate temperatures as low as 15 °C outside the den. Therefore it retires to the winter quarters around mid October. Green lezards are not vagrant and the male soften defend a territory of 200 to 1200 m². The mating period lasts from April to mid June. The males chase each other with muich noise through the vegetation and may fight quite vigorously. When mating, males bite the female into the tail and walk with it and finally hold fast to it with ist front legs. A male can mate with several females and those also mate several times before egg laying After three to six weeks the females lay 6 to 23 eggs, not too deep into lose sand or clay soil. 50 to 100 days later (depending upon the weather conditions) the young hatch. They are 3 to 4.5 cm long and unfortunately are sometimes eaten by the adults. Adults eat a variety of fod items, but mainly invertebrae, like beetles, locusts, caterpillars, woodlice, spiders, worms and snails, but also the juice of ripe berries (blackberries, red grapes or strawberries). Rarely they eat newborn lizards and small mice. Enemies of the green lizard are numerous (martens, weasel, birds of pray, snakes and house cats).

Green Iguana

Green, or common, iguanas are among the largest lizards in the Americas, averaging around 6.5 feet (2 meters) long and weighing about 11 pounds (5 kilograms).
They are also among the most popular reptile pets in the United States, despite being quite difficult to care for properly. In fact, most captive iguanas die within the first year, and many are either turned loose by their owners or given to reptile rescue groups.
The green iguana’s extensive range comprises the rain forests of northern Mexico, Central America, the Caribbean Islands, and southern Brazil. They spend most of their lives in the canopy, descending only infrequently to mate, lay eggs, or change trees.
Primarily herbivores, iguanas are active during the day, feeding on leaves, flowers, and fruit. They generally live near water and are excellent swimmers. If threatened, they will leap from a branch, often from great heights, and escape with a splash to the water below. They are also tough enough to land on solid ground from as high as 40 feet (12 meters) and survive.
Iguanas' stout build gives them a clumsy look, but they are fast and agile on land. They have strong jaws with razor-sharp teeth and sharp tails, which make up half their body length and can be used as whips to drive off predators. They can also detach their tails if caught and will grow another without permanent damage
Fairchild Tropical Garden has a large population of green iguanas, most likely escapees and releasees from the pet trade and their descendants. We saw a dozen large adults in a few hours, nearly all in pairs. Most of them would crash off into the vegetation or dive into the water when people got anywhere near, but this fellow posed nicely for me.
This lovely green Christmas iguana was lounging on a small dock in one of the numerous canals that criss-cross south Florida to increase the home values. It's missing the foot and foreleg on its front left leg. When it finally grew tired of me sneaking ever closer in the quest for photos, it calmly slipped over the edge of the dock, softly splashing into the water.

Information About Vampire Bat

known for what they eat. They feed on the blood of cattle, horses, other animals, and sometimes even people. Vampire bats can be dangerous because they can spread a disease called rabies, which can be deadly to those infected. To get to the blood of their animal victims, they bite away any fur or feathers, and then bite. They drink only small amounts of blood each time they feed. Vampire Bat, a bat that feeds on fresh blood. A number of large, fruit-eating bats are miscalled vampire bats. True vampire bats have upper incisor teeth shaped like canines. There are three species, found in various areas of Latin America.

Vampire bats have no tails and are about three inches (7.5 cm) long. They shelter in areas of almost complete darkness, such as eaves and hollow trees. To obtain their food, they will attack almost any warm-blooded animal that is resting quietly. After biting a victim, they suck the flowing blood. Although the wound and amount of blood lost are not serious, these bats are dangerous because they can transmit such diseases as rabies
Does a Vampire Bat Kill Its Prey? Vampire bats are very small mammals. They usually weigh about 1 ounce (28 grams). Their wingspan might measure 12 inches (30.5 centimeters) across. They eat only about 1 tablespoon (15 milliliters) of blood a day. Most animals never notice that they’ve been bitten by a vampire bat. The greater danger, though, is that vampire bats often spread diseases to their victims. If a vampire bat drinks the blood of an animal that has a disease, the bat can then carry the germs of that disease and spread them to other animals it bites. Sometimes the bat itself can become sick, as well.
A few kinds of bats feed on the blood of other mammals. These bats are called vampire bats.
Common vampire bats, which live in Mexico and South America, feed on the blood of horses, cattle, and fowl (birds such as chickens). Although it is rare, vampire bats can also feed on human blood.
A vampire bat searches for a sleeping animal. Then it lands nearby and climbs onto the animal. The bat uses its teeth to cut away the fur of the animal and quickly makes a small cut into the victim’s skin. Its teeth are so sharp that the sleeping animal doesn’t even feel the cut.
Once an animal starts bleeding, the vampire bat uses its tongue to lap up blood from the wound.

Vampire Bats are small flying mammals. They give birth to live young and nourish them with milk. They are nocturnal; they are most active at night and sleep during the day hanging upside-down. Vampire Bats live in Central and South America. Vampire Bats are microchiropterans, bats who use echolocation.
Anatomy: Bats' wings are long fingers covered by thin skin, and they have furry bodies. These tailless mammals have weak legs and don't walk very well. Vampire Bats have a wingspan of only 8 inches (20 cm). The body is the size of a person's thumb.
Senses/Diet: Vampire Bats can see, but use echolocation as their primary sense in order to find insects and small animals to eat. While flying, these bats send out high-pitched sounds that bounce off other objects. The bat listens for the bounced sound, and can determine where objects are located. People cannot hear these high-pitched sounds. The vampire bat is the only bat (and the only mammal) that eats blood, preying on cattle, horses, large birds and pigs. Vampire bats don't suck animals' blood, they make a small hole with their two very sharp incisor teeth and lap up the blood, which doesn't clot (thicken) because of anti-coagulants (anti-thickeners) in the bat's saliva.
