The Himalayan Monal

                                                           (Male Himalayan Monal)
The Himalayan monal (Lophophorus impejanus), also known as the Impeyan monalImpeyan pheasant, is a bird in the pheasant family, Phasianidae. It is the national bird of Nepal, where it is known as Danphe, and state bird of Uttarakhand India, where it is known as Monal. It was also the state bird of Himachal Pradesh, until 2007. Traditionally, the Himalayan monal has been classified as monophyletic. However, studies have shown that the male Himalayan monal of northwestern India lacks the white rump of other Himalayan monals, and it has more green on the breast, indicating the possibility of a second subspecies.
It is a relatively large-sized pheasant. The bird is about 70 centimeters long. The male weighs up to 2380 grams and the female 2150. The adult male has multicoloured plumage throughout, while the female, as in other pheasants, is dull in colour. Notable features in the male include a long, metallic green crest, coppery feathers on the back and neck, and a prominent white rump that is most visible when the bird is in flight. The tail feathers of the male are uniformly rufous, becoming darker towards the tips, whereas the lower tail coverts of females are white, barred with black and red. The female has a prominent white patch on the throat and a white strip on the tail. The first-year male and the juvenile resemble the female, but the first-year male is larger and the juvenile is less distinctly marked.

Distribution and habitat

he bird's natural range extends from eastern Afghanistan through the Himalayas in PakistanKashmir region and India (states of Himachal PradeshUttarakhandSikkim and Arunachal Pradesh), Nepal, southern Tibet, and Bhutan. There is also a report of its occurrence in Burma. It occupies upper temperate oak-conifer forests interspersed with open grassy slopes, cliffs and alpine meadows between 2400 and 4500 meters, where it is most common between 2700 and 3700 meters. It may descend to 2000 meters in the winter. It tolerates snow and will dig through it to obtain plant roots and invertebrate prey.
The breeding season is April through August, and they generally form pairs at this time. In winter they congregate in large coveys and roost communally.

Conservation


In some areas, the species is threatened due to poaching and other anthropogenic factors. In a recent study, the local population responded negatively to human disturbance involving hydroelectric power development. The male monal was under hunting pressure in Himachal Pradesh, where the crest feather was used to decorate men's hats, until 1982, when hunting was banned in the state.
In Pakistan the bird is most common in the Khyber Pakhtunkhwa province but it can also be found in KaghanPalas Valley, and Azad Kashmir. The pheasant is not considered endangered in the region and can be easily located. In some areas, the population density of the species is as high as five pairs per square mile. The main threat to the species is poaching, as the crest is valuable here, as well. It is thought to bring status to its wearer, and is a symbol of authority.

Tibetan Sand Fox(Vulpes Ferrilata)

The Tibetan sand fox (Vulpes ferrilata) is a species of true fox endemic to the high Tibetan PlateauLadakh plateau, Nepal, China, Sikkim, and Bhutan, up to altitudes of about 5300 m. It is classed as of "least concern" for extinction by the IUCN, on account of its widespread range in the Tibetan Plateau's steppes and semi-deserts.
It is sometimes referred to as the Tibetan fox, or simply as the sand fox, but this terminology is confusing because the corsac fox (Vulpes corsac), which lives in arid environments north and west of the Tibetan Plateau, is often called the "sand fox" or "Tibetan fox" as well. The Rüppell's fox (Vulpes rueppellii) is also known as the "sand fox".
Tibetan foxes are small and compact, with soft, dense coats and conspicuously narrow muzzles and bushy tails. Their muzzles, crowns, necks, backs and lower legs are tan to rufous coloured, while their cheeks, flanks, upper legs and rumps are grey. Their tails have white tips. The short ears are tan to greyish tan on the back, while the insides and undersides are white.Adult Tibetan foxes are 60 to 70 centimetres (24 to 28 in) from head to body (juveniles are somewhat smaller) and tail lengths of 29 to 40 centimetres (11 to 16 in). Weights of adults are usually 4 to 5.5 kilograms (8.8 to 12.1 lb).
Among the true foxes, their skulls are the most specialised in the direction of carnivory; they are longer in their condylobasal length and in mandible and cheek tooth length than those of hill foxes. Their cranial region is shorter than that of hill foxes, and their zygomatic arches narrower. Their jaws are also much narrower, and their foreheads concave. The canine teeth of Tibetan foxes are also much longer than those of hill foxes.

Distribution Habitat and Behaviour

The Tibetan sand fox is restricted to the Tibetan Plateau in western China and the Ladakh plateau in Northern Pakistan. It is found across Tibet, and in parts of the Chinese provinces of QinghaiGansuXinjiangYunnan and Sichuan. Outside of China, it can be found in northern Bhutan, and in the northernmost border regions of Nepal and India, north of the Himalayas. No subspecies are recognised.
The sand fox is found primarily in semi-arid to arid grasslands, well away from humans or from heavy vegetation cover. It inhabits upland plains and hills from 3,500 to 5,200 metres (11,500 to 17,100 ft) elevation, although it is occasionally seen on lower ground, down to 2,500 metres (8,200 ft).
They primarily prey on Plateau pikas, followed by rodentsmarmotswoolly hares and lizards. They may also scavenge on the carcasses of Tibetan antelopesmusk deerblue sheep and livestock. Tibetan foxes are mostly solitary, daytime hunters as their main prey, pikas, are diurnal. Tibetan foxes may form commensal relationships with brown bears during hunts for pikas. The bears dig out the pikas, and the foxes grab them when they escape the bears.
Mated pairs remain together and may also hunt together.After a gestation period of about 50 to 60 days, two to four young are born in a den, and stay with the parents until they are eight to ten months old. Their burrows are made at the base of boulders, at old beach lines and low slopes. Dens may have four entrances, with entrances being 25–35 cm in diameter.

Bengal Monitor(Dino)

The Bengal monitor has been said to reach nearly 175 cm with a snout-to-vent length (SVL) of 75 cm and a tail of 100 cm. Males are generally larger than females. Heavy individuals may weigh nearly 7.2 kg and obese captives even more and the males grow to greater weight. The populations of India and Sri Lanka differ in the scalation from those of Myanmar, and these were once considered two species, but now considered two subspecies. The nominate subspecies is found west of Myanmar, while nebulosus is found to the east. The subspecies nebulosus is diagnosed by the presence of a series of enlarged scales in the supraocular region. The number of ventral scales varies, decreasing from 108 in the west to 75 in the east (Java).
Young monitor lizards are more colourful than adults. Young have a series of dark crossbars on the neck, throat and back. The belly is white, banded with dark crossbars and are spotted with grey or yellow (particularly in the eastern part of the range). On the dorsal surface of young monitors, there are a series of yellow spots with dark transverse bars connecting them. As they mature, the ground colour becomes light brown or grey, and dark spots give them a speckled appearance. Hatchlings of nebulosus tend to have a series of backward-pointing, V-shaped bands on their necks.
Bengal monitors have external nostril openings (nares) that is slit-like and oriented near horizontal, and positions between the eye and the tip of the snout. The nares can be closed at will, especially to keep away debris or water. The scales of the skin are rougher in patches and on the sides, they have minute pits, especially well distributed in males. These scales with micropores have glandular structures in the underlying dermal tissue and produce a secretion which may be a pheromone-like substance. Like other varanids, Bengal monitors have a forked tongue that is protruded in the manner of snakes. The function is mainly sensory, and is not very involved in the transport of food down the throat. Bengal monitors have fat deposits in the tail and body that serve them in conditions when prey are not easily available.
The lungs have spongy tissue unlike the sacs of other saurians. This allows for greater rates of gas exchange and allows a faster metabolic rate and higher activity levels. Like all varanids, they have subpleurodont teeth, meaning the teeth are fused to the inside of the jaw bones. The teeth are placed one behind another, and there are replacement teeth behind and between each functional tooth (polyphyodont). The maxillary and dentary teeth are laterally compressed, sometimes with a slightly serrate cutting edge, while the premaxillary teeth are conical. There are 78 premaxillary teeth, 10 maxillary and 13 dentary teeth. Replacement teeth move forward and about four replacements happens each year for a tooth. Their mandibular glands produce secretions at the base of the teeth, and although some varanids have been shown to have a venom, no toxicity has been reported in the Bengal monitor.

Distribution,Habitat,Ecology and Behaviour

The species ranges from Iran to Java, among the most widely distributed of varanid lizards. It is found in river valleys in eastern IranAfghanistanIndiaNepalSri LankaBangladesh and Burma. The subspecies Varanus bengalensis nebulosus, the clouded monitor, occurs in southern BurmaVietnamCambodiaThailandMalaysiaSumatraJava and the Sunda Islands. They have not been confirmed on Sumatra, and have been found to be absent from the Andaman Islands.
The species is distributed mainly in the lower elevations, and is found both in dry semiarid desert habitats to moist forest. They are often found in agricultural areas, and are mainly found below 1500m altitude.
Bengal monitors are usually solitary and usually found on the ground, although the young are often seen on trees. V. b. nebulosus has a greater propensity for tree climbing. The two sympatric species Bengal and Yellow Monitor partially separated their habitat as Bengal Monitor prefers Forest over agricultural areas. Bengal monitors shelter in burrows they dig or crevices in rocks and buildings, whilst clouded monitors prefer tree hollows. Both races will make use of abandoned termite mounds. Bengal monitors, like other varanids, show true sleep at night and are diurnal, becoming active around 6 AM and bask in the morning sun. During winter, in the colder parts of their distribution range, they may take shelter and go through a period of reduced metabolic activity.They are not territorial, and may change their range seasonally in response to food availability.
They are usually shy and avoid humans. They have keen eyesight and can detect human movement nearly 250 m away. When caught, a few individuals may bite, but rarely do so.
Although, they are also found on agricultural land, they prefers forest with large trees. Generally, high ground cover with large trees are favorable areas.
Captives have been known to live for nearly 22 years. Predators of adults include pythons, mammalian predators and birds. A number of ectoparasites and endoparasites are recorded.

Breeding
Females may be able to retain sperm, and females held in confinement have been able to lay fertile eggs. Varanus niloticus has been demonstrated to be capable of parthenogenesis. The main breeding season is June to September. Males, however, begin to show combat behaviour in April. Females dig a nest hole in level ground or a vertical bank and lay the eggs inside, filling it up and using their snouts to compact the soil. The females often dig false nests nearby and shovel soil around the area. They sometimes make use of a termite mound to nest. A single clutch of about 20 eggs are laid. The eggs hatch in 168 to nearly as long as 254 days. About 40 to 80% of the eggs may hatch

Bird Found In Nepal Only'Spiny Babbler( Nepali: काँडे भ्याकुर)

                                                                     Spiny Babbler
The spineybabler (Turdoides nipalensisNepaliकाँडे भ्याकुर) is a species of bird in the family Leiothrichidae. It is found only in the middle hills of Nepal This animal was for the first time in the history found in Nepal by Miraj Adhikari. Sadly, this animal is about to go extinct.


Spiny Babbler is from the family of “Passerine Birds” a species of bird in the Timaliidae family. (Scientific name: Turdoides nipalensis) or (Kande Bhyakur in Nepali) It is a rare species of bird found only in Nepal. Nepal is blessed with different species of flora and fauna’s nevertheless we are high in numbers of birds too. Up till now Nepal has been recorded to have 867 species of birds, which rounds of to be about 8% of the total bird species found worldwide. We are home for total of 35 globally threatened species around the world and 19 proximate threatened species and 15 restricted-range species. “Spiny Babbler” is found in restricted range but till now researchers have reckoned the species aren’t to be under vulnerable category as the thresholds is summarized under the range size criterion.
It can be sighted easily around the heart of Nepal; the Kathmandu valley, distinctively around the Godavari and Phulchoki area. It is rarely to be foreseen by the human eyes but on the contrary the bird is very common. It is a medium sized bird with a sharp beak and is quite shy an elegant and spectacular brown bird. Though the ‘Spiny Babbler” doesn’t has its name on extinction but because of it scarce nature, it must be protected and should be given special attention. A genuine fact about “Kande Bhyakur; Spiny Babbler” is it was thought to be extinct for over centuries but later it suddenly came under everyone’s attention when “Sidney Dillon Ripley”, an American ornithologist came to know about its existence. The population size of this bird is unknown. They have a range restriction but it’s said that their population is stable till apparent condition.

Clouded Leopard(Neofelis nebulosa)

The scientific name of the clouded leopard is Neofelis nebulosa. It is one of two members of the genus Neofelis, and is classified under the family Felidae. It was first described by the British zoologist Edward Griffith in 1821. The other member of this genus is the Sunda clouded leopard (N. diardi), which was considered a subspecies of the clouded leopard until 2006. The clouded leopard is part of the Panthera lineage, one of the eight lineages of Felidae. This lineage comprises the species of Panthera and Neofelis. The Neofelis species diverged first from the lineage, followed by the snow leopard. Genetic analysis of hair samples of the two Neofelis species indicates that they diverged 1.4 million years ago, after having used a now submerged land bridge to reach Borneo and Sumatra from mainland Asia. Subsequent branching in the lineage is disputed. Broadly, two different cladograms have been proposed for the Panthera lineage. The clouded leopard is considered to form an evolutionary link between the big cats and the small cats. It represents the smallest of the big cats, but despite its name, it is not closely related to the leopard.



                                       Characteristics



The fur of clouded leopards is of a dark grey or ochreous ground-colour, often largely obliterated by black and dark dusky-grey blotched pattern. There are black spots on the head, and the ears are black. Partly fused or broken-up stripes run from the corner of the eyes over the cheek, from the corner of the mouth to the neck, and along the nape to the shoulders. Elongated blotches continue down the spine and form a single median stripe on the loins. Two large blotches of dark dusky-grey hair on the side of the shoulders are each emphasized posteriorly by a dark stripe, which passes on to the foreleg and breaks up into irregular spots. The flanks are marked by dark dusky-grey irregular blotches bordered behind by long, oblique, irregularly curved or looped stripes. These blotches yielding the clouded pattern suggest the English name of the cat. The underparts and legs are spotted, and the tail is marked by large, irregular, paired spots. Females are slightly smaller than males.
Their irises are usually either greyish-green or brownish-yellow in color. Their legs are short and stout, with broad paws. They have rather short limbs compared to the other big cats, but their hind limbs are longer than their front limbs to allow for increased jumping and leaping capabilities. Their ulnae and radii are not fused, which also contributes to a greater range of motion when climbing trees and stalking prey.
Melanistic clouded leopards are uncommon. Clouded leopards weigh between 11.5 and 23 kg (25 and 51 lb). Females vary in head-to-body length from 68.6 to 94 cm (27.0 to 37.0 in), with a tail 61 to 82 cm (24 to 32 in) long. Males are larger at 81 to 108 cm (32 to 43 in) with a tail 74 to 91 cm (29 to 36 in) long. Their shoulder height varies from 50 to 55 cm (20 to 22 in).
They have exceptionally long, piercing canine teeth, the upper being about three times as long as the basal width of the socket. The upper pair of canines may measure 4 cm (1.6 in) or longer. They are often referred to as a “modern-day sabre-tooth” because they have the largest canines in proportion to their body size, matching the tiger in canine length. The first premolar is usually absent, and they also have a very distinct long and slim skull with well-developed occipital and sagittal crests to support the enlarged jaw muscles.

                                Distribution and habitat

Clouded leopards occur from the Himalayan foothills in Nepal and India to MyanmarBhutanThailandPeninsular MalaysiaIndochina, and in China south of the Yangtze River. They are regionally extinct in Taiwan. Clouded leopards prefer open- or closed-forest habitats to other habitat types. They have been reported from relatively open, dry tropical forest in Myanmar and in Thailand.
In 2009, a few clouded leopards were sighted in the Chittagong Hill Tracts of south-eastern Bangladesh.Clouded leopards are mainly found in Kassalong Reserve of Rangamati-Khagrachory and Sangu Reserve forest in Banderban, all situated in Chittagong Hill Tracts. Few also remain in Kaptai National Park in Rangamati. Other than Chittagong Hill Tracts, there has been one sighting in Mymenshing in 2004, Mid East of Bangladesh and one uncertain report in North East Bangladesh.
In India, they occur in Assam, northern West BengalSikkimArunachal PradeshManipurMeghalayaMizoramNagaland, and Tripura. In the Himalayas, they were camera-trapped at altitudes of 2,500–3,720 m (8,200–12,200 ft) between April 2008 and May 2010 in the Khangchendzonga Biosphere Reserve, Sikkim.
Clouded leopards were thought to be extinct in Nepal since the late 1860s. But, in 1987 and 1988, four individuals were found in the central part of the country, close to Chitwan National Park and in the Pokhara Valley. These findings extended their known range westward, suggesting they are able to survive and breed in degraded woodlands that previously harboured moist subtropical semideciduous forest. Since then, individuals have been recorded in the Shivapuri Nagarjun National Park and in the Annapurna Conservation Area.

Special Type Of Elephant Found In Nepal

                              Wild Elephants in Nepal

Up until the 1960’s there was a large elephant population located in the lowland forest area of Nepal. However, rapidly rising human populations saw mass resettlement and land clearance which has had a devastating effect on elephant numbers.
Wild elephants in Nepal are often migratory visitors from Bengal. Most of the wild populations are found in small heavily fragmented groups with little chance of being viable in the long term. However one glimmer of light is within the boundaries of the Royal Bardia National Park, where a significant population increase has been recorded rising from 25 elephants in the early 90’s to over 50 individuals a decade later.
The Nepalese government has recognised the importance of elephant conservation and has established five protected reserves and an elephant breeding facility at Khorsor.

                      Domesticated Elephants in Nepal

The number of domesticated elephants in Nepal had been steadily declining from the turn of the 20th century to the 1970s. However the last 25-30 years has seen an increase in numbers. This reverse of trend is partially due to the increasing availability of work in the growing eco tourist industry and also a conscious decision by the Nepalese authorities to use domesticated elephants to conserve the wild population.
Most of the captive elephants are located in camps based around the National Parks and are used for tourist excursions. However, a small number are used to help with other conservation policies. Trained elephants were used to capture five wild rhinos that were translocated to create a viable family group and others have also been used in the forests to help count wild rhino and tiger.

Giant Hornbill In Nepal

The great hornbill is a large bird, 95–130 cm (37–51 in) long, with a 152 cm (60 in) wingspan and a weight of 2.15–4 kg (4.7–8.8 lb). It is the heaviest, but not the longest, Asian hornbill. Females are smaller than males and have bluish-white instead of red eyes, although the orbital skin is pinkish. Like other hornbills, they have prominent "eyelashes".
The most prominent feature of the hornbill is the bright yellow and black casque on top of its massive bill. The casque appears U-shaped when viewed from the front, and the top is concave, with two ridges along the sides that form points in the front, whence the Latin species epithet bicornis (two-horned). The back of the casque is reddish in females, while the underside of the front and back of the casque is black in males.
The casque is hollow and serves no known purpose, although it is believed to be the result of sexual selection. Male hornbills have been known to indulge in aerial casque butting, with birds striking each other in flight. The male spreads the preen gland secretion, which is yellow, onto the primary feathers and bill to give them the bright yellow colour.The commissure of the beak is black and has a serrated edge which becomes worn with age.
The wing beats are heavy and the sound produced by birds in flight can be heard from a distance. This sound has been likened to the puffing of a steam locomotive starting up. The flight involves stiff flaps followed by glides with the fingers splayed and upcurled. They sometimes fly at great height over forests.

Great hornbills are found in the forests of IndiaBhutanNepalMainland Southeast Asia, Indonesian Island of Sumatra and North eastern region of India. The distribution of the species is fragmented over its range in the Indian subcontinent and Southeast Asia. In the subcontinent they are found in a few forest areas in the Western Ghats and in the forests along the Himalayas. Their distribution extends into Thailand, Burma, Malaya, and Sumatra. A small feral population is found in Singapore. Their habitat is dense old growth (unlogged) forests in hilly regions.They appear to be dependent on large stretches of forest, unlike many of the smaller hornbills.
In Thailand the home range of males was found to be about 3.7 km2 during the breeding season and about 14.7 km2 during the non-breeding season.

Great hornbills are usually seen in small parties, with larger groups sometimes aggregating at fruit trees. A congregation of 150 to 200 birds has been recorded in southeastern Bhutan. In the wild, the great hornbill's diet consists mainly of fruit. Figs are particularly important as a food source. Vitex altissima has been noted as another important food source. Great hornbills also forage on lipid-rich fruits of the Lauraceae and Myristicaceae families such as PerseaAlseodaphne and Myristica.[17] They obtain the water that they need entirely from their diet of fruits. They are important dispersers of many forest tree species. They will also eat small mammals, birds, small reptiles and insects. Lion-tailed macaques have been seen to forage alongside these hornbills.
They forage along branches, moving along by hopping, looking for insects, nestling birds and small lizards, tearing up bark and examining them. Prey are caught, tossed in the air and swallowed. A rare squirrel, the Travancore flying squirrel (Petinomys fuscocapillus) has been eaten, and Indian scops owl (Otus bakkamoena), jungle owlet (Glaucidium radiatum) and Sri Lanka green pigeon (Treron pompadora) have been taken as prey in the Western Ghats.


During the breeding season (January to April) great hornbills become very vocal. They make loud duets, beginning with a loud "kok" given about once a second by the male, to which the female joins in. The pair then calls in unison, turning into a rapid mixture of roars and barks.They prefer mature forests for nesting. Large, tall and old trees, particularly emergents that rise above the canopy, seem to be preferred for nesting.] They form monogamous pair bonds and live in small groups of 2-40 individuals. Group courtship displays involving up to 20 birds have been observed.
The female hornbill builds a nest in the hollow of a large tree trunk, sealing the opening with a plaster made up mainly of feces. She remains imprisoned there, relying on the male to bring her food, until the chicks are half developed. During this period the female undergoes a complete moult. The young chicks have no feathers and appear very plump. The mother is fed by her mate through a slit in the seal. The clutch consists of one or two eggs, which she incubates for 38–40 days. The female voids feces through the nest slit, as do the chicks from the age of two weeks. Once the female emerges from the nest, the chicks seal it again.
The young birds have no trace of a casque. After the second year the front extremity separates from the culmen, and in the third year it becomes a transverse crescent with the two edges growing outwards and upwards, while the anterior widens to the width of the rear end. Full development takes five years.

Great One Horn Rhino(Rhinoceros Unicornis) Condition In Wrold

The greater one-horned rhino is a conservation success, with numbers increasing significantly since 1975. Back then there were only 600 rhinos left in the wild.

After decades of successful efforts, the species increased to 3,500 in India and Nepal by mid-2015. The one-horned rhino is now the most numerous of the three Asian rhino species.

Even so, the species faces the ever-present threat of poaching for its horn and continuing habitat loss.


Physical description 

The greater one-horned rhinoceros is the largest of the three Asian rhinos and, together with African white rhinos, is the largest of all rhino species. Males can weigh up to 2.7 tonnes.

The rhinos have a single black horn between 20-60 cm long and a grey-brown hide with skin folds, which give it an armor-plated appearance. The upper lip is semi-prehensile.


Behaviour

Greater one-horned rhinos are solitary, except when sub-adults or adult males gather at wallows or to graze. Males have loosely defined territories which are not well defended, and often overlap.

Females become sexually mature at 5-7 years old, while males mature at about 10. Breeding occurs throughout the year, with a gestation period of 15-16 months. The single offspring remains with the mother until the birth of her next calf, usually after 1 to 3 years.

The rhino is a primarily a grazer. Its diet consists almost entirely of grasses, but it also eats leaves, branches, fruit and aquatic plants.

Kalij(Lophura Leucomelanos) In Nepal


The kalij pheasant (Lophura leucomelanos) is a pheasant found in forests and thickets, especially in the Himalayan foothills, from Pakistan to western Thailand. Males are rather variable depending on the subspecies involved, but all have an at least partially glossy bluish-black plumage, while females are overall brownish. Both sexes have a bare red face and greyish legs (the latter separating it from the red-legged silver pheasant).[2] It is generally common and widespread, though three of its eastern subspecies (oatesilineata and crawfurdi) are considered threatened and moffitti is virtually unknown in the wild.[2]


The name is also spelt kaleege in old texts, such as Game Birds of India and Asia by Frank Finn,[3] though no longer in his Indian Sporting Birds.[4] It has also been introduced to Hawaii, where it is considered an invasive species because it consumes and disperses seeds of invasive plant species.
