Why is Chilika lake famous?

The largest brackish winter lagoon in Asia, the Chiluka Lake in Odisha spreads across more than 1,000 sq km comprises wide areas of manhes, lowlands and plenty of islands The fresh water from inland rivers and saline water from Bay of Bengal mix together to result in a unique ecosystem that supports rich biodiversity One of the largest wintering grounds in the country for migratory birds Chilika attracts tens of thousands of winged visitors even from as far as Mongolia and remote parts of Russia. The binds are ably supported by marine life marked by a variety of small fishes. The Chilika Lake comprises the chilika Bird Sanctuary and Nalbana Island also a bird sanctuary.

Wildlife

The birds one can spot in the region include ducks, geese, shelducks, pochards, flamingoes, grebes, doves, swifts, cuckoos, rails, crakes, storks, pelicans, bitterns, herons, egrets, ibises. cormorants, plovers, lapwings, jacanas, godwits, sandpipers, stints, snipes, redshanks, gulls, terms, vultures, kites, buzzards, eagles, owls. barbets, bee eaters, kingfishers, falcons, weavers. pipits, wagtails, larks, warblers, swallows. bulbuls, babblers, starlings and mynas, The area nurtures not just birds but also mammal species such as cheetal blackbuck mongoose and porcupines, and reptiles such as snakes, turtles and lizards. Some of the marine creatures found here are sharks, dolphins, stingrays, eels, herrings, anchovies, carbs. catfish, seahorses, mackerels, tunas and barracudas.

A million splendid birds!

The annual bird count held by the Chilika Wildlife Division early this year brought ecstatic news to bird lovers and conservationists. More than 11 lakh birds spanning as many as 184 species had arrived in Chilika. This is an increase from the previous years 10-lakh-odd birds from 183 species. Reports said that five rare great knot (a small wader) were sighted after a gap of five years in the region. The birds found hearty meals such as fish, prawns, frogs, snakes and molluscs in the open wetlands. The increase in bird numbers is said to be a reflection of a certain change in the lake. Previously, illegal prawn cultivation had taken up a part of the waterbody. This is believed to have ended after a high court order, resulting in more space for the birds.

The dolphin story

The Irrawaddy dolphin is an endangered species. And according to the report of a monitoring survey 2018, the Chilika lake emerged as the “single largest habitat of Irrawaddy dolphins in the world. The number of the dolphin population was estimated to be 155. Meanwhile, in May this year, media reports indicated that a research project undertaken the Indian Institute of Technology Madras helped in “tripling the population of the Irrawaddy dolphins”. in addition to a seven-fold increase in the fish population at Chilika. The sand bars were widening and the position of the sea mouth was changing, leading to the gradual degradation of the lake and calling for an urgent need to save its ecosystem. The researchers developed a dredging methodology and performed it with minimum impact on the ecosystem”, to successful and happy results.

Why do lions lick their prey a lot before they start eating it?

Like all felines (including the domestic cat), the lion’s tongue is covered in small, hook-shaped growths called papillae, which point towards the back of the mouth, and are used as a brush to separate flesh from fur and bone, particularly when the cat is feeding on a humongous kill (wildebeests, buffaloes, zebras…) – in the case of smaller prey items (rabbits, rodents, birds…), the carcass is devoured whole, with only a few or no bone splinters left.

Moreover, these papillae have the feeling of a hairbrush, resulting in the tongue becoming a rough surface – they’re sort of like hairs because they’re made of keratin, which is the same protein a human’s hairs and fingernails are composed of.

In the process, the feeding lion consumes the skin completely, and ensures itself that it never swallows (even accidentally!) small, pointy bones that could rip the cat’s throat, and that the meat is tenderized, which renders it efficiently digested.

Now, a lot of lions have seen to be licking prey they’ve just hunted, before killing and eating them. This mostly happens when the prey (usually an ungulate youngster) is brought alive by the lionesses to their cubs, so that the latter can hone their hunting skills – in the process, these cubs are too young to understand the art of hunting and the throttling bite that is essential to make a kill, so they instead resort to play with the animal by chasing it around; and when they subdue it, they don’t immediately kill it, but rather lick it, possibly as a means to display youth innocence.

This behavior mainly occurs with lion cubs (the youngsters, naturally), but it’s seen in adult lions too – in this case, it’s not always clear why. In my opinion, it could be psychological, in a way that the hunting lion either resorts to licking the animal in order to calm it – either it’s something done prior to giving the prey a quick death, or because something snapped inside the lion, a friendly, empathetic thought that made it reconsider its ferocious behavior, particularly since the hunted animal frantically panics from being attacked by a predator, emitting gut-wrenching cries for help –, or it’s just playing with its food (like house cats do), perhaps to torment the prey or simply tire it out so as to not risk injury. But I’m just speculating.

In the end, no one knows exactly why lions (the adults, to be precise) resort to licking their prey a lot while it’s still alive, prior to eating it.

What is famous in Jim Corbett National Park?

The oldest national park in the country, Jim Corbett National Park covers an area of more than 500 sq km and is located in Uttarakhand. It was known as Hailey National Park before it was renamed in the 1950s after hunter-turned-conservationist James Edward Corbett (popularly known as Jim Corbett), who played a significant role in setting it up. The Park is part of the larger Tiger Reserve of the same name. Located on the Himalayan foothills, the Park has streams and rivers running through it, helping nurture the varied landscapes there from rugged forests to grasslands. This mosaic of vegetation has also served as a magnet for several species of birds and animals. The region is noted especially for its tiger and elephant population. In fact, Corbett has the highest number of tigers in the country – 213, according to the report of the fourth All India Tiger Estimation 2018 released on the eve of Global Tiger Day (July 29), 2020. Corbett hosts more than 550 species of birds, and has been declared an “Important Bird Area” by Birdlife International.

Wildlife

The birds found in the region include pelicans, darters, cormorants, grebes, storks, ibises, pochards, shelducks, hawks, grions, harriers, falcons, kestrels, francolins. partridges, quails, pheasants, crakes, swamphens, moorhens, watercocks, jacanas, lapwings, plovers, sandpipers, snipes, stints, redshanks, coucals, nightjars, hornbills, barbets, woodpeckers, martins, magpies, minivets, fantails, warblers, prinias, robins, tits, nuthatches, wagtails, weavers, and buntings. Apart from the Royal Bengal tiger and the Asiatic elephant, one may spot the gharial, sloth bear, Himalayan black bear, hog deer, sambar, marsh crocodile, rhesus macaque, mongoose, otter, jackal, pangolin, python and the cobra too.

Hello, rhinos!

Though famed for its tigers, Corbett is all set to welcome a new kind of inhabitant – Assam’s famed one-horned rhinoceros. In November 2019, the Uttarakhand Wildlife Advisory Board approved a proposal for rhino translocation on an experimental basis. As part of the proposal, more than one dozen rhinos from the Kaziranga National Park will find a home in Uttarakhand’s most popular National Park. It is said that the region is conducive for the mammals, and is also less plagued by human-animal conflict. Reports suggest that Corbett was perhaps a natural habitat of the pachyderms since a male rhino was sighted towards the end of the 18th Century. What inspired the proposal could be the similar translocation and eventual success of nearly half-a-dozen rhinos from Assam’s Pobitora to Uttar Pradesh’s Dudhwa National Park way back in 1984.

Popularity is a threat…

• The Park has for long received a large number of visitors. While tourism is integral to the development of any natural habitat it cannot be at the cost of the region itself. The huge number of visitors, infrastructure development around the Park to host these visitors, the clearing of land to set up activities for the tourists, the dumping of garbage into the river flowing through the Park etc. are among the greatest threats to the Park With increasing number of visitors, the chances of human animal conflicts too increase. drawing attention to the need to find a healthy balance between tourism and income generation for the region.

• This February, more than a month before the COVD-19 pandemic gripped the country, a photograph shot inside the Corbett Tiger Reserve went viral on social media It showed two tigers playing with what appears to be a plastic object. Indicative of how much plastic has invaded eco-sensitive regions, conservationists termed it a tragedy and called for public awareness and sensitivity. Ironically, plastic is banned in the Reserve.

• In 2016, Uttarakhand experienced one of its worst forest fires in recent times. Among several other areas Corbett too suffered. It was reported that about 200 hectares of forests were reduced to ashes. Though animal deaths were not reported forest fires can push escaping animals into human habitation leading to conflicts. Worse, several adult and young animals could perish or be injured significantly reducing the chances of new generations of animals to survive and grow, and leaving existing populations vulnerable.

How do balloon releases harm wildlife?

Balloons, glitters and confetti add colour to our celebrations. But did you know while we treat ourselves to these small pleasures, we inadvertently pollute Earth? After all, what goes up must come down. Free-flying balloons and confetti ultimately become litter and put animals and birds at risk.

Balloons

Balloons are of two types – latex and mylar. Although latex balloons are promoted as biodegradable, they take anywhere between six months and four years to decompose. Mylar balloons are composed of synthetic nylon with a metallic coating. They are non biodegradable.

Balloons (when released into the sky, say as part of events or campaigns) travel thousands of miles, capable of polluting the most remote and pristine places. Deflated balloons that settle on land and sea surface are mistaken for food and eaten by animals and birds. They get lodged in their digestive tract, causing obstruction, loss of nutrition, internal injury, starvation, and death. String or ribbon often found attached to balloons can cause entanglement in animals, again leading to their death. Animals such as sea turtles are at special risk because the balloons resemble their favourite food – jellyfish. Seabirds are not safe either. According to a study released in 2019, if a seabird swallows a balloon, it’s 32 times more likely to die than if it had gulped down a piece of hard plastic.

Glitter and confetti

Confetti has been used for thousands of years. The tradition can be traced back to the pagan times when people tossed grains and sweets during weddings and festivals. It has been adopted by many cultures around the world. But in recent years, it has taken a different form. We toss confetti and glitter at weddings and stage performances today, which simply disperse microplastics everywhere. Because confetti and glitter are made of plastic – polyvinyl chloride (PVC) and polyethylene terephthalate (PET), respectively.

Microplastics are plastic particles that are less than 5mm in diameter and are an emerging environmental issue. Glitter is usually less than 1mm in diameter and is used in a wide array of products, including cosmetics. It leads into the environment and often ends up in the oceans. It can be accidentally consumed by plankton, fish, shellfish, seabirds, and other marine life. When microplastic builds up in their systems, it can lead to death.

Further, PET, the plastic most glitter is made from, can break down and release chemicals that can disrupt human and animal hormones.

Which are the diseases that wipe out wildlife?

Chytridiomycosis

Chytridiomycosis is an infectious disease that affects amphibians worldwide. It is caused by the chytrid fungus (Batrachochytrium dendrobatidis), leading to deaths in frogs, toads and salamanders. A report released in 2019 revealed that it has caused declines in at least 501 frog and salamander species in the last 50 years.

Of these, some 90 species are presumably extinct in the wild and 124 are suffering serve declines due to the disease, the report said. In many species, the fungus is the main factor in the deaths, but in others, it’s a combination of the disease and other factors such as habitat loss, climate change and predation from invasive species.

Chytrid fungi that infect vertebrate species live in water or soil. They reproduce asexually and have spores that swim in the water. Amphibians contract the disease when their skin comes in contact with water containing spores or with other affected amphibians. The fungus affects their skin, making it difficult for them to breathe (amphibians use their skin for respiration). The fungus also damages the nervous system, affecting their behaviour. It doesn’t kill the amphibians immediately, which increases the odds of the pathogen spreading rapidly.

The disease is thought to have spread around the world via the pet and meat trade.

Chytridiomycosis has affected amphibian populations in more than 60 countries, with the largest die-offs in Australia, Central America and South America.

Devil Facial Tumour Disease

The Tasmanian devil, a marsupial native of Australia, has suffered a dramatic population decline due to Devil Facial Turmour Disease (DFTD). First discovered in northeastern Tasmania in 1996, the disease has since spread across 95% of the species’ range. Up to 90% of their populations have been wiped out.

The disease is spread through biting during fighting or mating. It spreads particularly when canine teeth come into contact with the diseased cells. The rough cells then settle down in their new host, developing into tumours on face, neck and other parts of the body. The devils soon find it difficult to eat and drink, and usually die from starvation and dehydration. The cancer also affects other bodily functions such as respiration and blood circulation. An infected devil dies within six months. According to some predictions, DFTD could wipe out wild Tasmanian devils in less than 40 years.

White-Nose Syndrome

White-Nose Syndrome (WNS) is a fungal disease that has killed over six million bats in North America in over a decade. Caused by the fungus Pseudogymnoascus destructans, or Pd, the disease has spread to 33 U.S. States and seven Canadian provinces. Some populations have declined by more than 90 % within five years of the disease reaching a site. As of 2017, 15 bat species have been affected by WNS.

The fungus infects the skin on the nose, mouth,ears and wings of hibernating bats. The fungus thrives in cold and humid environments such as caves and mines used by bats. Bats can catch the fungus from physical contact with infected bats. The signs observed in bats with WNS include unusual winter behaviour-they experience frequent arousal from sleep and instead of continuing with the hibernation, the bats fly far out of their caves, even in daylight. As a result they quickly drain their fat reserves, and starve to death, Infected bats also show evidence of blood acidification and dehydration.

Sea Star Wasting Syndrome

Sea Star Wasting Syndrome (SSWS) has been linked to the mass die-offs of starfish and several other echinoderms (such as sea urchins, sand dollars and sea cucumbers) since 2013 in the Pacific waters from Mexico to Alaska. In 2014, it was suggested that the disease is caused by densovirus; but subsequent work revealed that an association between a viral pathogen and SSWS was unlikely.

The symptoms begin with white lesions on their limbs, decay of tissue surrounding the lesions and loss of limbs. The sea star would eventually turn into a mushy blob and die. Forty species of sea stars have been affected by this disease.

Research has shown that warming ocean temperatures could play a role in exacerbating the disease. But the actual causative agent for SSWS remains elusive.

Hemorrhagic Septicemia

One day in May 2015, a handful of saiga antelops were found dead in the steppe of Kazakhstan. The next day saw more deaths. Within three weeks, some 2,00,000 – 62% of the world’s population – were dead. This alarmed the scientists from across the globe as the species was already critically endangered in Central Asia. The reported symptoms were foaming at the mouth, diarrhoea and bloating. Initial research revealed it could be due to a disease. A 2018 report confirmed that the killar was a bacterium, Pasteurella multocida, that normally lives in the antelopes’ tonsils without causing any problems. It also revealed that unusually warm, moist weather may have triggered the overgrowth of the bacteria, which subsequently found its way into the antelopes’ tissues and bloodstream, causing haemorrhagic septicaemia or  fatal blood poisoning. Researchers say there is a high chance of the same thing happening again, given the climate change predictions for the region.

Similar die-offs were reported in 2010 and 1988. They were also linked to Pasteurella multocida. Today, roughly 50,000 saigas are thought to remain in the wild, according to the World Wildlife Fund.

Why do cheetahs have a tear line?

Cheetahs have two tear lines that run from the inside corners of their eyes down to the outside edges of their mouth. These marks help reflect the sun’s glare whenever the cats are off hunting during the sunniest of days – in that way, cheetahs don’t get blinded by direct sunlight like we do, even in midday.

The tear lines work in a similar way to the black marks worn by rugby players. They’re also helpful features for the cheetah in order to stay focused on its prey.

There is a Zulu folklore tale about how the cheetah got its tear lines: once, a hunter was too lazy to be about his business, wishing that someone could get the meat for him. Soon, he saw a female cheetah making a successful kill and feeding it to her cubs, and all of a sudden decided to steal all these cubs in order to train them for hunting.

Soon, when the mother cheetah was away, the wicked hunter accomplished his terrible deed, kidnapping all the cubs without leaving a single one. Once the mother found her babies gone, she became heartbroken, searched for them far and wide, and kept calling and crying all day and night, so long and so hard, until her tears made dark stains down her cheeks.

Soon, the elders got wind of the event and went to punish the lazy hunter, who had also broken the tribe’s most sacred traditions – in Zulu culture, it’s tradition that a hunter must use only his own strength and skill, otherwise dishonor comes. But even when the wicked man was eventually forced to bring the cubs back to their mother, nevertheless her long weeping stained her face forever – and those tears are worn by her children (modern-day cheetahs) to this day.

According to the locals, this tale carries a moral: a cheetah wearing the tear stains on its face is a reminder for hunters that it is not honorable to hunt in a non-traditional, inconvenient way.

Which animal is believed to be dangerous but is actually altogether harmless?

While many animals in the world look dangerous and live up to their frightening appearances, there are many others which pose little to no threat to us humans.

Here’s my list of 7 scary looking animals that are practically harmless.

1. Gharial

Many people would be right to fear a gharial if they’ve heard stories about how other crocodilians kill hundreds of humans each year, but is this slim snouted creature really as dangerous as its cousins?

In truth, gharials only hunt small prey like fish and frogs as their jaws are too slim and weak to take down larger quarry. As a result gharials are unable to attack large prey, namely humans.

2. Milk snake

While, the milk snake may bear a striking resemblance to the venomous coral snake they are completely harmless. They have no venom and are actually quite docile in nature which makes them pretty good pets for reptile lovers.

3. Sand tiger shark

Most people know that sharks in general don’t deserve their fearsome reputation as an eating monsters but very few of them are completely harmless. While, the great white, tiger and bull shark have all been known to kill people, the sand tiger shark is actually completely harmless.

This shark’s barbed jaws may look threatening but these scary looking teeth are exactly what keep this fish from being even a slight danger towards us. The shark’s mouth is too small to cause a human fatality so only squid and fish fall victim to this shark’s jaws. While this shark is very docile there have been a few attacks when it’s been provoked…

4. Goliath bird eater

Goliath bird eating spiders may have venom. They may take down small birds and they may be freaking massive but are they really a danger towards humans?

In truth this tarantula’s venom is harmless and is quite similar to how a wasp’s sting would feel. Main difference is that these spiders only bite in self defense, so I’m pretty sure you won’t be bothered by this giant.

5. Manta rays

Manta rays are very large and if you have ever heard of sting rays, you might be frightened by this aquatic creature. Manta rays are actually gentle giants and are only filter feeders, meaning they eat really small prey. To make things better, they don’t have stingers so divers have nothing to fear!

6. Thorny devil

These lizards may be small but I’m pretty sure most of us would be scared if this spiky reptile came charging. Luckily this animal only feeds on insects and when it does feel threatened it squirts blood from its eyes…which may seem gross but wouldn’t really harm a human being. To make things even better, these scary looking lizards run at the first sight of a human being!

7. Basking shark

The second-largest shark species is pretty harmless despite its frightening set of jaws. Like many of the ocean’s largest predators, this creature is a filter feeder and that means humans aren’t on the menu!

Why do tigers and lions never fight each other?

It’s because Lions and Tigers do not co-exist in a shared territory anymore (thanks to humans).

However Tigers and Lions used to share common habitats in Asia, specially India and Iran before the end of 20th century. Fights between these two beasts were recorded in the accounts of travellers, folklore and stories.

20th Century had been the worst century for animals in these regions. Both British and Indian/Persian Royals hunted down Tigers and Lions in huge numbers, bounty was put on them and due to rapid urbanization and huge agricultural demands their habitats were run over by human occupation.

Lions were less of a shy animal compared to Tigers which preferred to hide in deep forests, so Lions were killed more, so much so that Lions went locally extinct in Iran and most of India.

Only 12 were left in a small forest in Gujarat, India by the end of 20th Century. They were able to survive because King of that region decided to protect them.

Tigers also perished as they were also hunted down to near extinction.

They became extinct in Iran and were only able to survive in small pockets of forests in India.

So, if not so for relentless hunting of Wild Animals by humans in 20th Century, Tigers and Lions would had still co-existed with each other in Jungles of Persia and India, and we may had witnessed Tigers and Lions fighting over territory and prey in the wild itself.

Why duckbill platypus have pouch?

The duckbill platypus uses its cheek pouches to store food. Its pouches come in handy when it goes down to the bottom of the river to gather its food, mainly insect larvae, water snails and crustaceans.

These Australian mammals are bottom feeders. They scoop up insects and larvae, shellfish, and worms in their bill along with bits of gravel and mud from the bottom. All this material is stored in cheek pouches and, at the surface, mashed for consumption. Platypuses do not have teeth, so the bits of gravel help them to “chew” their meal.

Why walrus have pouch?

The walrus has a pouch on its throat, which inflates with air and props the animal up when it goes to steep in an upright position in the water.

The only natural predators for walruses are polar bears, orcas and humans.

Adult females are generally smaller than males, with an average weight of about 1,900 lbs and an average length of approximately 9 feet.  Calves of both sexes weigh between 100 to 150 pounds and are about 4.5 feet in length.

The scientific name for walrus, Odobenus rosmarus, means “toothwalkers.”

Adult Pacific walrus can eat up 4.2 to 6.2 percent of their total body weight (1760-4000 pounds) each day – that’s between 74 and 250 pounds of food per day!
