SNOW LEOPARD



The snow leopard (Panthera uncia), also known as the ounce, is a large cat native to the mountain ranges of Central and South AsiaIt is listed as Vulnerable on the IUCN Red List because the global population is estimated to number less than 10,000 mature individuals and is expected to decline about 10% by 2040. It is threatened by poaching and habitat destruction following infrastructural developments.


 FACTS


  • ⧫ STATUS
       Vulnerable
⧫ POPULATION
   total estimated 4,080-6,590

⧫ SCIENTIFIC NAME
   Panthera uncia

⧫ LENGTH
   2-5 ft.

⧫ HABITAT
  cold high mountains          
Snow leopards have evolved to live in some of the harshest conditions on Earth. Their white-gray coat spotted with large black rosettes blends in perfectly with the steep and rocky mountains of Central Asia. The snow leopard’s powerful build allows it to scale great steep slopes with ease. Its hind legs give the snow leopard the ability to leap six times the length of its body. A long tail provides balance and agility and also wraps around the resting snow leopard as protection from the cold. 


THE KEY


Snow leopards play a key role as both top predator and as an indicator of the health of their high-altitude habitat. If snow leopards thrive, so will countless other species.







HABITAT

Potential snow leopard habitat in the Indian Himalayas is estimated at less than 90,000 km2 (35,000 sq mi) in the states of Jammu and KashmirUttarakhandHimachal PradeshSikkim, and Arunachal Pradesh, of which about 34,000 km2 (13,000 sq mi) is considered good habitat, and 14.4% is protected. In the beginning of the 1990s, the Indian snow leopard population was estimated at roughly 200–600 individuals living across about 25 protected areas.

In summer, snow leopards usually live above the tree line on mountainous meadows and in rocky regions at altitudes from 2,700 to 6,000 m (8,900 to 19,700 ft). In winter, they come down into the forests to altitudes around 1,200 to 2,000 m (3,900 to 6,600 ft). Snow leopards prefer rocky, broken terrain, and can travel without difficulty in snow up to 85 cm (33 in) deep, although they prefer to use existing trails made by other animals.


BEHAVIOR

The snow leopard's vocalizations include meowing, grunting, prusten, and moaning. It can purr when exhaling. It cannot roar, despite possessing partial ossification of the hyoid bone. This partial ossification was previously thought to be essential for allowing the Panthera cats to roar, but new studies show that the ability to roar is due to other morphological features, especially of the larynx, which are absent in the snow leopard.

Snow leopards are solitary animals, but share a common space. They are active mostly at dawn until early morning and again in afternoons and early evening


HUNTING

 The snow leopard is a carnivore and actively hunts its prey. It is an opportunistic hunter and also eats carrion.

Snow leopards prefer to ambush prey from above, using broken terrain to conceal their approach. They will actively pursue prey down steep mountainsides, using the momentum of their initial leap to chase animals for up to 300 m (980 ft). They kill with a bite to the neck, and may drag the prey to a safe location before feeding. They consume all edible parts of the carcass, and can survive on a single Himalayan blue sheep for two weeks before hunting again. Annual prey needs appears to be 20–30 adult blue sheep.


LIFE CYCLE

Snow leopards become sexually mature at two to three years, and normally live for 15–18 years in the wild. In captivity they can live for up to 25 years. Oestrus typically lasts from five to eight days, and males tend not to seek out another partner after mating, probably because the short mating season does not allow sufficient time.

Paired snow leopards mate in the usual felid posture, from 12 to 36 times a day. They are unusual among large cats in that they have a well-defined birth peak. They usually mate in late winter, marked by a noticeable increase in marking and calling. Females have a gestation period of 90–100 days, so the cubs are born between April and June.

The mother gives birth in a rocky den or crevice lined with fur shed from her underside. Litter sizes vary from one to five cubs, but the average is 2.2. The cubs are blind and helpless at birth, although already with a thick coat of fur, and weigh from 320 to 567 g (11.3 to 20.0 oz). Their eyes open at around seven days, and the cubs can walk at five weeks and are fully weaned by 10 weeks. Also when they are born, they have full black spots which turn into rosettes as they grow to adolescence.

The cubs leave the den when they are around two to four months of age, but remain with their mother until they become independent after around 18–22 months. Once independent, they disperse over considerable distances, even crossing wide expanses of flat terrain to seek out new hunting grounds. This likely helps reduce the inbreeding that would otherwise be common in their relatively isolated environments.



THREATS

The sole predator of snow leopards? Humans. Hunting, habitat loss and retaliatory killings are the main reasons this big cat is under threat.

Snow leopards are often killed by local farmers because they prey on livestock such as sheep, goats, horses, and yak calves. The animals which snow leopards would typically hunt—such as the Argali sheep—are also hunted by local communities. As their natural prey becomes harder to find, snow leopards are forced to kill livestock for survival.

The snow leopard habitat range continues to decline from human settlement and increased use of grazing space. This development increasingly fragments the historic range of the species.

CLIMATE CHANGE

Climate change poses perhaps the greatest long-term threat to snow leopards. Impacts from climate change could result in a loss of up to 30 percent of the snow leopard habitat in the Himalayas alone.


That all from me, thank you for reading this. see you in the next post !!
