King vulture Birds King vulture beautifull birgs

King Vulture, Sarcoramphus papa, is a large bird found in Central and South America. It is a member of the New World vulture family Cathartidae. This vulture lives predominantly in tropical lowland forests stretching from southern Mexico to northern Argentina, though some believe that William Bartram's Painted Vulture of Florida may be of this species. King Vulture is the largest of the New World vultures. Its overall length ranges from 67–81 centimeters (27–32 in) and its wingspan is 1.2–2 meters (4–6.6 ft). Its weight ranges from 2.7–4.5 kilograms (6–10 lb). An imposing bird, the adult King Vulture has predominantly white plumage, which has a slight rose-yellow tinge to it. In stark contrast, the wing coverts, flight feathers and tail are dark grey to black, as is the prominent thick neck ruff. The head and neck are devoid of feathers, the skin shades of red and purple on the head, vivid orange on the neck and yellow on the throat.

King Vulture has gray to black ruff, flight, and tail feathers. The head and neck are bald, with the skin color varying, including yellow, orange, blue, purple, and red. The King Vulture has a very noticeable yellow fleshy caruncle on its beak. This vulture is a scavenger and it often makes the initial cut into a fresh carcass. behavior is typical of caracaras, but the larger and shorter-legged King Vultures are not well adapted for walking. This bird was believed to be common and conspicuous in Bartram's days, but it is notably absent from Bartram's notes if the Painted Vulture is accepted as a Sarcoramphus.
The vulture’s head and neck are featherless as an adaptation for hygiene, though there are black bristles on parts of the head; this lack of feathers prevents bacteria from the carrion it eats from ruining its feathers and exposes the skin to the sterilizing effects of the sun. In South America, it does not live west of the Andes except in western Ecuador north-western Colombia and far north-western Venezuela. It primarily inhabits undisturbed tropical lowland forests as well as savannas and grasslands with these forests nearby. It is often seen near swamps or marshy places in the forests. This bird is often the most numerous or only vulture present in primary lowland forests in its range, but in the Amazon rainforest it is typically outnumbered by the Greater Yellow-headed Vulture, while typically outnumbered by the Lesser Yellow-headed, Turkey and American Black Vulture in more open habitats. King Vultures generally do not live above 1500 m (5000 ft), although are found in places at 2500 m (8000 ft) altitude east of the Andes, and have been rarely recorded up to 3300 m (10000 ft) They inhabit the emergent forest level, or above the canopy.

King Vulture soars for hours effortlessly, only flapping its wings infrequently. While in flight, its wings are held flat with slightly raised tips, and from a distance the vulture can appear to be headless while in flight. Its wing beats are deep and strong. Birds have been observed engaging in tandem flight or two occasions in Venezuela by naturalist Marsha Schlee, who has proposed it could be a part of courtship behaviour.
Groups of up to 12 birds have been observed bathing and drinking in a pool above a waterfall in Belize. One or two birds generally descend to feed at a carcass, although occasionally up to ten or so may gather if there is significant amount of food. King Vultures have lived up to 30 years in captivity, though their lifespan in the wild is unknown. This vulture uses urohidrosis, defecating on its legs, to lower its body temperature.

King Vulture eats anything from cattle carcasses to beached fish and dead lizards. In forests, it is likely to eat sloth. Principally a carrion eater, there are isolated reports of it eating injured animals, newborn calves and small lizards.
Although it locates food by vision, the role smell has in how it specifically finds carrion has been debated. Consensus has been that it does not detect odours, and instead follows the smaller Turkey and Greater Yellow-headed Vultures, which do have a sense of smell, to a carcass but a 1991 study demonstrated that the King Vulture could find carrion in the forest without the aid of other vultures, suggesting that it locates food using an olfactory sense. The King Vulture primarily eats carrion found in the forest, though it is known to venture onto nearby savannas in search of food. Once it has found a carcass, the King Vulture displaces the other vultures because of its large size and strong bill. However, when it is at the same kill as the larger Andean Condor, the King Vulture always defers to it. Using its bill to tear, it makes the initial cut in a fresh carcass. This allows the smaller, weaker-beaked vultures, which can not open the hide of a carcass, access to the carcass after the King Vulture has fed.

the King Vulture in the wild is poorly known, and much knowledge has been gained from observing birds in captivity particularly at the Paris Menagerie. An adult King Vulture sexually matures when it is about four or five years old, with females maturing slightly earlier than males. The birds mainly breed during the dry season. King Vultures mate for life and generally lay a single unmarked white egg in its nest in a hollow in a tree. To ward off potential predators, the vultures keep their nests foul-smelling. Both parents incubate the egg for the 52 to 58 days before it hatches. If the egg is lost, it will often be replaced after about six weeks. The parents share incubating and brooding duties until the chick is about a week old, after which they often stand guard rather than brood. The young are semi-altricial—they are helpless when born but are covered downy feathers (truly altricial birds are born naked), and their eyes are open at birth. Developing quickly, the chicks are fully alert by their second day, and able to beg and wriggle around the nest, and preen themselves and peck by their third day.

King Vulture is one of the most common species of birds represented in the Mayan codices. Its glyph is easily distinguishable by the knob on the bird’s beak and by the concentric circles that make up the bird’s eyes. Sometimes the bird is portrayed as a god with a human body and a bird head. According to Mayan mythology, this god often carried messages between humans and the other gods. It is also used to represent Cozcaquauhtli, the thirteenth day of the month in the Mayan calendar 13 Reed.

The eastern bluebird is the only one of the 3 bluebird species regularly found in Louisiana. Bluebirds are usually found in fields, open woodlands, parks or along golf courses or other open areas, including suburban locations with open spaces and scattered tress. The eastern bluebird has a musical flight call that often reveals its presence.

It may enter human dwellings when hunting. It restlessly moves from place to place in search of prey, which mainly consists of mice, rats, poultry, frogs and snakes. Normaly, it is not considered aggressive, particularly shy of human beings and will avoid confrontation. Habitually it avoids confrontation with man, at a chance en-counter, first priority is to escape undetected. On sensing danger it lifts anterior part of its body to have a good look at its surroundings. If not provoked, it lets fall it's body and slips quietly away. However, if provoked, it hisses loudly and sways its hood to advertise its presence, and displays the hood markings to impress its adversary. It fixes its eyes to the source or annoyance, keenly following its movements. However, all the time at the lookout to have a chance to avoid conrontation and slip away. The swaying of hood with dorsal spectacle mark and ventral yellow ocellus, coupled with loud hiss, arc measures to just look as fearsome and as big as possible, to impress the enemy. Cobra attacks viciously and furiously, striking with full strength and biting savagely, chewing the bitten pan. When bitting, it hold on and chews savagely. May strike repeatedly. Pairings are known to be for life, breeding activity is observed from April to July, 12 to 30 eggs are laid in rat holes or crevices, female stays close until hatching.

Cobra frequents different habitats: grasslands, vegetation along tilled fields, along water courses, semidesert forests, barns, ruins with grassy growths and around villages. It is plentiful in paddy growing areas, where it is attracted bv mice and poultry into living houses. It climbs into the branches of trees in search of nesting birds. Often it become resident in rat holes after consuming its occupant.

N.n.naja is found in eastern Pakistan as far west as Karachi. It has been reported from sea level to 4000m in the Himalayas. It may be found in flat grasslands, among scattered trees, near rice fields and other cultivated areas, near settlements. Usually not found in deserts or rainforests. This cobra species is found in Punjab, Baluchistan and Sind where it is quiet common. reclamation and overgrazing are the main threats to the cobras in Pakistan. Every year thousands of cobras are killed in Pakistan for their skins. Snake charmers capture cobras to stage fights with mongoose in rural and urban areas. Cobras are locally used by aurevedic practitioners in their recipes.

Longnose gar fish

longnose gar, Lepisosteus osseus, is a primitive ray-finned fish of the gar family. It is also known as the needlenose gar. longnose gar ranges in length from 60–182 cm (24–72 in) and weighs 0.5–3.5 kg (1.1–7.7 lb); The world record is 50.31 pounds, caught in Trinity River, Texas in 1954; FishBase reports a maximum size of 2 m (6.6 ft). Average life span is 17- 20 years. The snout is elongated into a narrow beak containing many large teeth.

Longnose gar at the Steinhart Aquarium.Although angling for longnose gars is not the dominant method of capturing them due to their tough, bony mouth, they will take live baits. They are more often captured by specialized methods that entangle the teeth in nylon threads, by bowfishing, or by spearfishing.
If angling for gar, a small circle hook should be used, allowing the gar several minutes with it. The circle hook will prevent any serious injury to the gar, as it is designed to catch only in the corner of the mouth.

longnose gar is found in rivers and lakes throughout the eastern half of the United States, as far north as southern Quebec and extreme southern Ontario in the Great Lakes and as far south as northern Mexico. The most concentrated numbers of longnose gars are found throughout the American Deep South, Texas, Alabama (Cahaba River system) and anywhere along the Mississippi River.

Long nosed bandicoot

Long-nosed Bandicoot (Perameles nasuta) is a species of bandicoot found in Australia. It is the largest member of its genus, which also includes the Western Barred Bandicoot, the Eastern Barred Bandicoot and the Desert Bandicoot.

Gestation period
12 days (average)
Birth Mass
Age at sexual or reproductive maturity (female)
135 days (average)
The gestation period of the long-nosed bandicoot is quite short, about 12.5 days. There can be 1-5 young in a litter, with the usual number being 2 or 3. Bandicoots have a placental structure (but it lacks the villae in the placenta of placental mammals), and the young remain attached to this by umbilical cords for some time after birth, until the young begin suckling on teats in the pouch. Young are weaned at about 60 days, and the mother may have the next litter only a few days after the previous one is weaned.

The Long-nosed Bandicoot is much less colourful than its relatives, being primarily a brown colour. It is distributed along the eastern coast of Australia from Cairns in Queensland to Naringal in southwestern Victoria.
