Golden Eagle (Aquila chrysaetos) is one of the best known birds of prey in the Northern Hemisphere. Like all eagles, it belongs to the family Accipitridae. Once widespread across the Holarctic, it has disappeared from many of the more heavily populated areas. Despite being extirpated from some its former range or uncommon, the species is still fairly ubiquitous, being present in Eurasia, North America, and parts of Africa. The highest density of nesting Golden Eagles in the world lies in southern Alameda County, California. They will also eat carrion if prey is scarce, as well as reptiles. Birds, including large species up to the size of swans and cranes as well as ravens and Greater Black-backed Gulls have all been recorded as prey. They have even been known to attack and kill fully grown roe deer.

They are monogamous and may remain together for several years or possibly for life. Golden Eagles nest in high places including cliffs, trees, or human structures such as telephone poles. They build huge nests to which they may return for several breeding years.

Golden Eagle is a large, dark brown raptor with broad wings. Its size is variable: it ranges from 66 to 100 cm (26 to 39 in) in length and it has a typical wingspan of 1.8 to 2.34 m (5.9 to 7.7 ft). In the largest race (A. c. daphanea) males and females weigh 4.05 kg (8.9 lb) and 6.35 kg (14.0 lb). In the smallest subspecies (A. c. japonensis), the sexes weigh, respectively, 2.5 kg (5.5 lb) and 3.25 kg (7.2 lb). The maximum size of the huge eagles is a matter of some debate, although captive birds have been measured to a wingspan of 2.81 m (9.2 ft) and a mass of 12.1 kg (27 lb). Sexes are similar in plumage but are considerably dimorphic in size, with females rather larger than males. Adults are primarily brown, with gold on the back of the crown and nape, and some grey on the wings and tail.

Golden Eagles usually mate for life. They build several eyries within their territory and use them alternately for several years. These nests consist of heavy tree branches, upholstered with grass when in use. Old eyries may be 2 metres (6.6 ft) in diameter and 1 metre (3.3 ft) in height, as the eagles repair their nests whenever necessary and enlarge them during each use. If the eyrie is situated on a tree, supporting tree branches may break because of the weight of the nest.

The eggs vary from all white to white with cinnamon or brown spots and blotches. They start incubation immediately after the first egg is laid, and after 40 to 45 days the young hatch.[citation needed] They are covered in fluffy white down and are fed for fifty days before they are able to make their first flight attempts and eat on their own. In most cases only the older chick survives, while the younger one dies without leaving the eyrie. This is due to the older chick having a few days' advantage in growth and consequently winning most squabbles for food. This strategy is useful for the species because it makes the parents' workload manageable even when food is scarce, while providing a reserve chick in case the first-born dies soon after hatching. Golden Eagles invest much time and effort in bringing up their young; once able to hunt on their own, most Golden Eagles survive many years, but mortality even among first-born nestlings is much higher, in particular in the first weeks after hatching.

Bactrian camel (Camelus bactrianus) is a large even-toed ungulate native to the steppes of central Asia. It is presently restricted in the wild to remote regions of the Gobi and Taklamakan Deserts of Mongolia and Xinjiang. There are a small number of wild Bactrian camels still roaming the Mangystau Province of South West Kazakhstan. It is one of the two surviving species of camel. It has been discovered that a population of wild Bactrian camel lives within a part of the Gashun Gobi region of the Gobi Desert. This population is distinct from domesticated herds both in genetic makeup[8] and in behavior.[citation needed.

There are possibly as many as three regions in the genetic makeup that are distinctly different from domesticated camels and there is up to a 3% difference in the base genetic code. However, with so few wild camels, it is unclear what the natural genetic diversity within a population would have been. Bactrian camel was identified as one of the top ten "focal species" in 2007 by the Evolutionarily Distinct and Globally Endangered (EDGE) project, which prioritises unique and threatened species for conservation.

These rare animals may not look like primates at first glance, but they are related to chimpanzees, apes, and humans.

Aye-ayes are dark brown or black and are distinguished by a bushy tail that is larger than their body. They also feature big eyes, slender fingers, and large, sensitive ears. Aye-ayes have pointed claws on all their fingers and toes except for their opposable big toes, which enable them to dangle from branches.

While perched aloft, the aye-aye taps on trees with its long middle finger and listens for wood-boring insect larvae moving under the bark. It employs the same middle finger to fish them out. The digit is also useful for scooping the flesh out of coconuts and other fruits that supplement the animal's insect diet. Many people native to Madagascar consider the aye-aye an omen of ill luck. For this reason they often have been killed on sight.

grasshopper is an insect of the suborder Caelifera in the order Orthoptera. To distinguish it from bush crickets or katydids, it is sometimes referred to as the short-horned grasshopper. They also have pinchers or mandibles that cut and tear off food. Those species that make easily heard noises usually do so by rubbing the hind femurs against the forewings or abdomen (stridulation), or by snapping the wings in flight. Tympana, if present, are on the sides of the first abdominal segment. The hind femora are typically long and strong, fitted for leaping. Generally they are winged, but hind wings are membranous while front wings (tegmina) are coriaceous and not fit for flight. Females are normally larger than males, with short ovipositors.

Only one of the 8000 species of grasshopper will only eat a single species of plant.
The digestive system of insects includes a foregut (stomodaeum, the mouth region), a midgut (mesenteron), and a hindgut (proctodaeum, the anal region). The mouth is distinct due to the presence of a mandible and salivary glands. The mandible can chew food very slightly and start mechanical digestion. Salivary glands digest the food chemically, though only carbohydrates in the grasses and such they eat. The mouth leads to the muscular pharynx, and through the esophagus to the crop. The crop has the ability to hold food. From the crop, food enters the gizzard, which has teeth like features in it. From there, food enters the stomach. In the stomach, digestive enzymes mix with the food to break it down.

salivary glands and midgut secrete digestive enzymes. The midgut secretes protease, lipase, amylase, and invertase, among other enzymes. The particular ones secreted vary with the different diets of grasshoppers.
The one closed organ, the dorsal vessel, extends from the head through the thorax to the hind end. It is a continuous tube with two regions: the heart, which is restricted to the abdomen; and the aorta, which extends from the heart to the head through the thorax. Haemolymph is pumped forward from the hind end and the sides of the body through a series of valved chambers, each of which contains a pair of lateral openings (ostia). The haemolymph continues to the aorta and is discharged through the front of the head.

Black mamba snakes

noreply@blogger.com (niaz khan) — Sat, 1 Oct 2011 22:03:00 -0700

Black mamba snakes life history:
black mamba (Dendroaspis polylepis) is the longest venomous snake in Africa, averaging around 2.5 meters (8.2 ft), and sometimes growing up to 4.3 meters (14 ft). Its name is derived from the black colouration inside the mouth rather than the actual colour of the skin which varies from dull yellowish-green to a gun-metal grey. It is the fastest snake in the world, capable of moving at 4.32 to 5.4 metres per second (16–20 km/h, 10–12 mph). black mamba's back skin colour is olive, brownish, gray, or sometimes khaki. The adult snake's length is on average 2.5 meters (8.2 ft) but some specimens have reached lengths of 4.3 to 4.5 meters (14 to 15 ft). Black mambas weigh about 1.6 kilograms (3.5 lb). on average. The species is the second longest venomous snake in the world, exceeded in length only by the king cobra. black mamba lives in Africa, occupying the following range: Northeast Democratic Republic of the Congo, southwestern Sudan to Ethiopia, Eritrea, Somalia, Kenya, Eastern Uganda, Tanzania, southwards to Mozambique, Swaziland, Malawi, Zambia, Zimbabwe and Botswana to KwaZulu-Natal in South Africa, and Namibia; then northeasterly through Angola to southeastern Zaire. The black mamba is not commonly found above altitudes of 1000 metres (3280.8 feet), although the distribution of black mamba does reach 1800 metres (5905.5 feet) in Kenya and 1650 metres (5413.3 feet) in Zambia. The black mamba was also recorded in 1954 in West Africa in the Dakar region of Senegal.

The majority of human attacks occur in the sugarcane fields of east and southern Africa in which are employed thousands of workers for manual labour, as cane growing is not a highly mechanised industry.
It is known to be capable of reaching speeds of around 20 kilometers per hour (12 mph), traveling with up to a third of its body raised off the ground. Over long distances the black mamba can travel 11 to 19 kilometers per hour (6.8 to 12 mph), but in short bursts it can reach a speed of 16 to 20 kilometers per hour (9.9 to 12 mph),or even 23 kilometers per hour (14 mph) making it the fastest land snake. It is shy and secretive; it always seeks to escape when a confrontation occurs. If a black mamba is cornered it mimics a cobra by spreading a neck-flap, exposing its black mouth, and hissing.

Some of the components of the venom have a much more toxic LD50 value than the venom as a whole, for example α-dentrotoxin (or "Toxin 1") and γ-dendrotoxin (or "Toxin 7") had subcutaneous LD50 values of 0.09 µg and 0.12 µg per gram of white mice, respectively. Although only 10 to 15 mg is deadly to a human adult, its bite delivers about 100–120 mg of venom on average but they can deliver up to 400 mg of venom in a single bite. It is reported that before the antivenom was widely available, the mortality rate from a bite was 100 Black mamba bites can potentially kill a human within 20 minutes or less depending on the nature of the bite and the area bitten, but death usually occurs after 30–60 minutes on average, sometimes even taking up to three hours. British wildlife enthusiast Nathan Layton was bitten by a juvenile black mamba and died within minutes.

The fatality duration and rate depend on various factors, such as the health, size, age, psychological state of the human, the penetration of one or both fangs from the snake, amount of venom injected, location of the bite, and proximity to major blood vessels. In extreme cases, when the victim has received a large amount of venom, death can result within minutes from respiratory or cardiac arrest. This is especially true if the victim is bitten in the face or chest area, as a black mamba can rear up around one-third of its body from the ground which puts it at about four feet high. When warding off a threat, the black mamba delivers multiple strikes, injecting large amounts of virulently toxic venom with each strike, often landing bites on the body or head, unlike other snakes.

The dendrotoxins disrupt the exogenous process of muscle contraction by means of the sodium potassium pump. Toxin K is a selective blocker of voltage-gated potassium channels Toxin 1 inhibits the K+ channels at the pre and post-synaptic level in the intestinal smooth muscle. It also inhibits Ca2+-sensitive K+ channels from rat skeletal muscle‚ incorporated into planar bilayers (Kd = 90 nM in 50 mM KCl) Toxin 3 inhibits M4 receptors, while Toxin 7 inhibits M1 receptors. The calciseptine is a 60 amino acid peptide which acts as a smooth muscle relaxant and an inhibitor of cardiac contractions.

Cobra is a large and powerful snake, averaging 3 to 4 meters (9.8 to 13 ft) in length and typically weighing about 6 kilograms (13 lb). The longest known specimen was kept captive at the London Zoo, and grew to around 18.5 to 18.8 feet (5.6 to 5.7 m) before being euthanized upon the outbreak of World War II. The heaviest wild specimen was caught at Royal Island Club in Singapore in 1951 which weighed 12 kilograms (26 lb) and measured 4.8 meters (16 ft), though an even heavier captive specimen was kept at New York Zoological Park and was measured as 12.7 kilograms (28 lb) at 4.4 meters (14 ft) long. They can be distinguished from other cobras by size and hood marks. King cobras are generally larger than other cobras, and the stripe on the neck is like the symbol "^" instead of a double or single eye(s) shape that may be seen in most of the other Asian cobras. A foolproof method of identification is if on the head, clearly visible, is the presence of a pair of large scales known as occipitals, at the back of the top of the head.

Armadillo

noreply@blogger.com (niaz khan) — Thu, 22 Sep 2011 08:30:00 -0700

Armadillos are New World placental mammals, known for having a leathery armor shell. Dasypodidae is the only surviving family in the order Cingulata, part of the superorder Xenarthra along with the anteaters and sloths. Their average length is about 75 centimetres (30 in), including tail; the Giant Armadillo grows up to 150 centimetres (59 in) and weighs up to 59 kilograms (130 lb), while the Pink Fairy Armadillos are diminutive species with an overall length of 12 to 15 centimetres (5 to 6 in). Many species are endangered. Some species groups, such as the long-nosed armadillos, are widely distributed over the Americas, whereas others, such as the fairy armadillos, are concentrated in smaller ranges in South America. One species, the nine-banded Armadillo (Dasypus novemcinctus), is found in the United States, primarily in the south central states (notably Texas), but with a range that extends as far east as South Carolina and Florida
The Nine-banded Armadillo prefers to build burrows in moist soil near the creeks, streams, and arroyos around which it lives and feeds. The diet of different armadillo species varies, but consists mainly of insects, grubs, and other invertebrates. Some species, however, feed almost entirely on ants and termites.

In common with other xenarthrans, armadillos in general have low body temperatures (33–36 °C) and basal metabolic rates (from 40–60% of that expected in a placental mammal of their mass). The North American Nine-banded Armadillo tends to jump straight in the air when surprised, and consequently often collides with the undercarriage or fenders of passing vehicles.

Armadillos have short legs but can move quite quickly, and have the ability to remain underwater for as long as six minutes. Because of the density of its armor, an armadillo will sink in water unless it inflates its stomach and intestines with air, which often doubles its size and allows it to swim across narrow bodies of water. They are particularly susceptible due to their unusually low body temperature, which is hospitable to the leprosy bacterium, Mycobacterium leprae. (The leprosy bacterium is difficult to culture and armadillos have a body temperature of 34 °C, similar to human skin.) Humans can acquire a leprosy infection from armadillos by handling them or consuming armadillo meat, and are a presumed vector and natural reservoir for the disease in Texas and Louisiana. Armadillos (mainly Dasypus) make common roadkill due to their habit of jumping to about fender height when startled (such as by an oncoming car). Wildlife enthusiasts are using the northward march of the armadillo as an opportunity to educate others about the animals, which can be a burrowing nuisance to property owners and managers.

Bison

noreply@blogger.com (niaz khan) — Wed, 14 Sep 2011 23:30:00 -0700

The American bison and the European wisent are good swimmers and are the largest terrestrial animals in North America and Europe. Bison are nomadic grazers and travel in herds, except for the non-dominant bulls, which travel alone or in small groups during most of the year. American bison are known for living in the Great Plains. Both species were hunted close to extinction during the 19th and 20th centuries but have since rebounded. there are a number of physical and behavioural differences between the American and European bison. The American species has 15 ribs, while the European bison has 14. The American bison has four lumbar vertebrae, while the European has five. Adult American bison are not as rangy in build, and have shorter legs. American bison tend to graze more, and browse less than their European cousins .

The body of the American bison is typically hairier, though its tail has less hair than that of the European bison. The horns of the European bison point through the plane of their faces, making them more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison which favours butting.

A bison wallow is a shallow depression in the soil, either wet or dry. Bison roll in these depressions, covering themselves with mud or dust. Possible explanations suggested for wallowing behavior include grooming behavior associated with moulting, male-male interaction (typically rutting behavior), social behavior for group cohesion, play behavior, relief from skin irritation due to biting insects, reduction of ectoparasite load (ticks and lice), and thermoregulation.

Their most obvious weapons are the horns borne by both males and females. But their massive heads can be used as battering rams, effectively using the momentum produced by 2,000 pounds (900 kg) moving at 30 mph (50 km/h). The hind legs can also be used to kill or maim with devastating effect. At the time bison ran wild, they were rated second only to the Alaska brown bear as a potential killer, more dangerous than the grizzly bear. In the words of early naturalists, they were a dangerous, savage animal that feared no other animal and in prime condition could best any foe.
The rutting, or mating, season lasts from June through September with peak activity in July and August.

stink bugs

noreply@blogger.com (niaz khan) — Sun, 11 Sep 2011 10:11:00 -0700

stink bugs or shield bugs, is referred to a super family of insects belonging to the Heteroptera suborder. In this order the insects share common characteristics such as piercing mouth-parts as well as a particular kind of wings which are toughened at the base and membranous at the tips.

Brown Stink Bugs
The scientific name of stink bugs, Pentatomoidea, has been derived from the fact that they have an antenna which is divided into five segments. Stink bugs have broad bodies that are either in triangular shape or semi-elliptical. Their bodies serve the purpose of defensive shield against predators; this is why they are sometimes referred to as "shield bugs".

Brown Marmorated Stink Bugs, scientifically known as Halyomorpha halys, are insects in Pentatomoidea family found in Asian counties like China and Japan. The size of adult brown stink bugs varies from individual to individual ranging from 1.5 cm long to 2 cm. When they are nymphs, they are red in color which becomes black and ultimately brown as soon as they become adults.

Albatross sea bird

noreply@blogger.com (niaz khan) — Sun, 11 Sep 2011 09:32:00 -0700

History
Albatrosses, of the biological family Diomedeidae, are large seabirds allied to the procellariids, storm-petrels and diving-petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic. They feed on squid, fish and krill by either scavenging, surface seizing or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several species nesting together. Pair bonds between males and females form over several years, with the use of 'ritualised dances', and will last for the life of the pair.

Numbers of albatrosses have declined in the past due to harvesting for feathers, but today the albatrosses are threatened by introduced species such as rats and feral cats that attack eggs, chicks and nesting adults; by pollution; by a serious decline in fish stocks in many regions largely due to overfishing; and by long-line fishing.

Albatrosses, along with all Procellariiformes have a need to lower their salt content due to drinking sea water. All birds have an enlarged nasal gland at the base of the bill, above their eyes. This gland is inactive in species that don't require it, but the Procellariiformes do require its use. Scientists are uncertain as to its exact processes, but do know in general terms that it removes salt that forms a 5% saline solution that drips out of their nose or is forcibly ejected in some birds.

The adult plumage of most of the albatrosses is usually some variation of dark upper-wing and back, white undersides, often compared to that of a gull. the species range from the Southern Royal Albatross which is almost completely white except for the ends and trailing edges of the wings in fully mature males, to the Amsterdam Albatross which has an almost juvenile-like breeding plumage with a great deal of brown, particularly a strong brown band around the chest.

Diet and Breading
fish, crustaceans, and offal although they will also scavenge carrion and feed on other zooplankton. It should be noted that for most species, a comprehensive understanding of diet is only known for the breeding season, when the albatrosses regularly return to land and study is possible. The importance of each of these food sources varies from species to species, and even from population to population; some concentrate on squid alone, others take more krill or fish. Of the two albatross species found in Hawaii, one, the Black-footed Albatross, takes mostly fish while the Laysan feeds on squid.
Light-mantled Albatrosses regularly dive to feed, and can dive to below 12 m.The use of dataloggers at sea that record ingestion of water against time (providing a likely time of feeding) suggest that albatross predominantly feed during the day.

they are found on exposed headlands with good approaches from the sea in several directions, like the colony on the Otago Peninsula in Dunedin, New Zealand. Many Buller's Albatrosses and Black-footed Albatrosses nest under trees in open forest. Colonies vary from the very dense aggregations favoured by the mollymawks (Black-browed Albatross colonies on the Falkland Islands have densities of 70 nests per 100 m²) to the much looser groups and widely spaced individual nests favoured by the sooty and great albatrosses. All albatross colonies are on islands that historically were free of land mammals. Albatrosses are K-selected with regard to their life history, meaning they live much longer than other birds, they delay breeding for longer, and invest more effort into fewer young. Albatrosses are very long lived; most species survive upwards of 50 years, the oldest recorded being a Northern Royal Albatross that was ringed as an adult and survived for another 51 years, giving it an estimated age of 61. Young non-breeders will attend a colony prior to beginning to breed, spending many years practising the elaborate breeding rituals and "dances" that the family is famous for. Birds arriving back at the colony for the first time already have the stereotyped behaviours that compose albatross language, but can neither "read" that behaviour as exhibited by other birds nor respond appropriately. After a period of trial and error learning, the young birds learn the syntax and perfect the dances. This language is mastered more rapidly if the younger birds are around older birds.

The repertoire of behaviour involves synchronised performances of various actions such as preening, pointing, calling, bill clacking, staring, and combinations of such behaviours (like the sky-call). When a bird first returns to the colony it will dance with many partners, but after a number of years the number of birds an individual will interact with drops, until one partner is chosen and a pair is formed. They then continue to perfect an individual language that will eventually be unique to that one pair.

In all albatross species, both parents incubate the egg in stints that last between one day and three weeks. Incubation lasts around 70 to 80 days (longer for the larger albatrosses), the longest incubation period of any bird. It can be an energetically demanding process, with the adult losing as much as 83 g (2.9 oz) of body weight a day.

After hatching, the chick, which is semi-altricial is brooded and guarded for three weeks until it is large enough to defend and thermoregulate itself. During this period the parents feed the chick small meals when they relieve each other from duty. After the brooding period is over, the chick is fed in regular intervals by both parents. The parents adopt alternative patterns of short and long foraging trips, providing meals that weigh around 12% of their body weight (around 600 g (21 oz)). The meals are composed of both fresh squid, fish and krill, as well as stomach oil, an energy-rich food that is lighter to carry than undigested prey items. This oil is created in a stomach organ known as a proventriculus from digested prey items by most tubenoses, and gives them their distinctive musty smell.

Albatrosses brood young chicks until they are large enough to thermoregulate.Albatross chicks take a long time to fledge. In the case of the great albatrosses, it can take up to 280 days; even for the smaller albatrosses, it takes anywhere between 140 and 170 days. Like many seabirds, albatross chicks will gain enough weight to be heavier than their parents, and prior to fledging they use these reserves to build up body condition (particularly growing all their flight feathers), usually fledging at the same weight as their parents.

Penguin pictures and history

noreply@blogger.com (niaz khan) — Fri, 9 Sep 2011 03:59:00 -0700

Penguins (order Sphenisciformes, family Spheniscidae) are a group of aquatic, flightless birds living almost exclusively in the southern hemisphere, especially in Antarctica. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have become flippers. Most penguins feed on krill, fish, squid, and other forms of sealife caught while swimming underwater. They spend about half of their lives on land and half in the oceans.

These were not restricted to Antarctic regions; on the contrary, subantarctic regions harboured high diversity, and at least one giant penguin occurred in a region not quite 2,000 km south of the equator 35 mya, in a climate decidedly warmer than today.

as some sources suggest.
A third theory states that the word is an alteration of “pen-wing”, with reference to the rudimentary wings of great auks. This has been criticised for the unexplained nature of the alteration of the word.

Penguins for the most part breed in large colonies, the exceptions being the Yellow-eyed and Fiordland species; these colonies may range in size from as few as a 100 pairs for Gentoo Penguins, to several hundred thousand in the case of King, Macaroni and Chinstrap Penguins.

Penguins generally only lay one brood; the exception is the Little Penguin, which can raise two or three broods in a season.

Penguin eggs are smaller than any other bird species when compared proportionally to the weight of the parent birds; at 52 g (2 oz), the Little Penguin egg is 4.7% of its mothers' weight, and the 450 g (1 lb) Emperor Penguin egg is 2.3%.[49] The relatively thick shell forms between 10 and 16 % of the weight of a penguin egg, presumably to minimise risk of breakage in an adverse nesting environment. The yolk, too, is large, and comprises 22–31 % of the egg. Some yolk often remains when a chick is born, and is thought to help sustain it if parents are delayed in returning with food.

History
African rock python adult measures 4.8 m (16 ft). Rumors of specimens over 6 m (20 ft) are considered reliable, although larger specimens have never been confirmed. Males are typically smaller than females, with the largest one ever recorded measuring 4.4 m (14.5 ft) and weighing 62.6 kg (138 lb), caught in southern Florida. The snake varies considerably in body size between different areas. In general, it is smaller in highly populated regions, such as in southern Nigeria, only reaching its maximum length in areas such as Sierra Leone, where the human population density is lower.

The African rock python's body is thick and covered with colored blotches, often joining up in a broad, irregular stripe. Body markings vary between brown, olive, chestnut, and yellow, but fade to white on the underside.

African rock python is found throughout almost the whole of sub-Saharan Africa from Senegal east to Ethiopia and Somalia and south to Namibia and South Africa. Python sebae sebae ranges across central and western Africa, while Python sebae natalensis has a more eastern and southerly range, from southern Kenya to South Africa.
In 2009, the African rock python was found in the Florida Everglades, and is feared to be establishing itself as an invasive species alongside the already-established Burmese Python.

Feding
the African rock python is non-venomous and kills its prey by constriction. After gripping the prey, the snake coils around it, tightening its coils every time the victim breathes out. Death is thought to be caused by cardiac arrest rather than by asphyxiation or crushing. The African rock python feeds on a variety of large rodents, monkeys, warthog, antelopes, fruit bats, monitor lizards and even crocodiles in forest areas, and on rats, poultry, dogs and goats in suburban areas.

Bullfrogs

noreply@blogger.com (niaz khan) — Wed, 7 Sep 2011 08:02:00 -0700

American bullfrog, Rana catesbeiana often simply known as the bullfrog in Canada and the United States, is an aquatic frog, a member of the family Ranidae, or “true frogs”, native to much of North America. This is a frog of larger, permanent water bodies, swamps, ponds, and lakes, where it is usually found along the water's edge. The adult bullfrog skeleton is representative of tetrapod vertebrates, comprising an axial skeleton (skull and vertebrae) and an appendicular skeleton (pectoral girdle and forelimbs, pelvic girdle and hindlimbs). Ranids, however, lack ribs. The pronounced pair of dorsal humps in the back of ranid frogs are the ends of the pelvic ilia, homologues of the human hips. When in the air, as opposed to underwater, frogs continuously elevate and lower the floor of the mouth, which serves to ventilate the mouth, or buccal cavity, and exchange gases through the richly vascularized lining of the mouth. Periodically, the regular rhythmic pumping of the floor of the mouth is interrupted by a deeper lowering of the throat, at the extreme of which, the glottis opens and the throat muscles contract vigorously to force air from the mouth into the lungs—the nostrils are closed off. Fertilization is external in ranid frogs. In the mating grasp, or amplexus, the male rides on top of the female, grasping her with his forelimbs posterior to her forelimbs. The female bullfrog deposits her eggs in the water and the male simultaneously releases sperm.

Breeding begins in late spring or early summer. Males defend and call from territories, attracting females into a territory to mate. The call is reminiscent of the roar of a bull, hence the frog's common name. A female may produce up to 20,000 eggs in one clutch.

Beautifull Egret sea birds

Great Egret (Ardea alba), also known as the Great White Egret or Common Egret, White Heron, or (now not in use) Great White Heron is a large, widely-distributed egret. Distributed across most of the tropical and warmer temperate regions of the world, in southern Europe it is rather localized. In North America it is more widely distributed, and it is ubiquitous across the Sun Belt of the United States and in the rainforests of South America. It is sometimes confused with the Great White Heron in Florida, which is a white morph of the closely related Great Blue Heron (A. herodias). It is thus only slightly smaller than the Great Blue or Grey Heron (A. cinerea). Apart from size, the Great Egret can be distinguished from other white egrets by its yellow bill and black legs and feet, though the bill may become darker and the lower legs lighter in the breeding season. In breeding plumage, delicate ornamental feathers are borne on the back.
