Sarus Crane


Sarus-Crane


Sarus Crane

The large Sarus Crane is the only resident crane of Indian Subcontinent mostly found in south to the Godavari River, west to coastal Gujarat,Punjab,east to West Bengal and Assam.

Sarus Crane is the largest of Indian cranes with a maximum height of about 5.9 ft making them the world’s tallest flying bird.

The population of Sarus Crane is declining in the country so falls in the category of endangered species of bird in India. 

Sarus Crane species was a close contender to the Indian Peafowl as the national bird of India.

How Australians hunted crocodiles in 1949


Published on Apr 7, 2016

From the Film Australia Collection. Made by the National Film Board 1949. Directed by Lee Robinson. In the estuaries and lagoons of the Northern Territory, freshwater and saltwater crocodile are hunted for their hides by both Indigenous and non-Indigenous hunters. This film shows Aboriginal people using age-old hunting techniques to land crocs either for food or for skins. The methods employed by the professional hunters, who earn as much as 3000 pounds during the season, are also depicted, followed by a brief look at how the hides are skinned and prepared before being transported to the leather factories of Sydney and Melbourne.

Incredible video shows how Australians hunted crocodiles in 1949

It's a long way from the time of Crocodile Dundee, but new footage is giving insights into the origin of the crocodile hunter.
To time with the 30th anniversary of the release of the iconic Australian film, the National Film and Sound Archive (NSA) released this incredible vision from 1949.
The government film, directed by acclaimed director Lee Robison, documents the involved process of killing crocodiles in the lagoons of the Northern Territory.
"These rivers and billabongs are home of the crocodile: cunning, ferocious killer, frightened of nothing on land or in the water," the British narrator said. "Sometimes it's a lonely life and sometimes dangerous but, for a man with the courage to do battle with the man-eaters, there are rich rewards."
In this era, crocodiles were hunted by Indigenous and non-Indigenous hunters. This film contrasts the traditional methods used by the Indigenous hunters with the use of shotguns by white men.
The Daly River's Brinkin tribe shown in the documentary hunt crocodiles as a food source, using harpoons, bamboo and their own bare hands. The crocodiles caught by the non-Indigenous hunters are for the leather hides, which are then skinned, prepared and transported to factories in capital cities. 
"The Aborigines have perfected many hunting techniques and the cunning crocodile is outsmarted every time by the skill of master hunters," the narrator said. "The professional crocodile hunters who now shoot along the rivers of the north, use different methods and more modern equipment than the Aborigines. They kill for leather skins and not for food."
NFSA's Richard Carter told ABC Darwin radio it is interesting that you get to see in a film from this time both the Indigenous way and the white way, but he believed it was a film to promote Australian industries to the country. 

"It's an interesting contrast," Carter said. "For a film so early, you don't always get that complete picture of what's going on, but in this you get to see all sides."

Killer Nile Crocodiles in Florida

Killer Nile crocodiles in Florida? Experts say it's possible



FORT LAUDERDALE, Fla. (AP) —

Step aside, Burmese python — you may no longer be Florida's scariest invasive species.

Researchers have confirmed that three Nile crocodiles were captured near Miami, and they say it's possible more of the man-eating reptiles are still out there, although no one can say for sure.

The big question now: How did they get to Florida?


"They didn't swim from Africa," University of Florida herpetologist Kenneth Krysko said. "But we really don't know how they got into the wild."

Krysko and his co-authors just published a paper showing that DNA testing proved the three animals captured in 2009, 2011 and 2014 are Nile crocs, a species whose males grow to over 16 feet long and weigh upward of 1,600 pounds. Nile crocs are believed to be responsible for up to 200 fatalities annually in their native sub-Saharan Africa. Compare that with an annual average of six reported shark attack deaths globally.

Krysko, who works at UF's Florida Museum of Natural History, said the captured crocodiles matched genetically, meaning they are related to one another, but didn't match Nile crocs kept at Disney's Animal Kingdom and other licensed Florida attractions. That means the crocs probably were brought to Florida illegally by an unlicensed reptile collector who either didn't contain them properly, allowing them to escape, or, more sinisterly, planted them in the Everglades in hopes they would multiply.

The Nile croc, if it became established in the Everglades, would pose another invasive threat to its teetering ecosystem. Through crossbreeding, they could endanger the smaller, less aggressive American crocodiles, which have never been responsible for a confirmed human death in the U.S. About 1,000 American crocodiles live in South Florida, mostly in mangroves and estuaries. Any hybrids would degrade the genetic integrity of the endangered American variety.

Nile crocs also are known to attack livestock, which would be bad news for cattle farms that border the Everglades.

Krysko and two co-authors, independent wildlife biologist Joe Wasilewski and UF wildlife ecology professor Frank Mazzotti, think more Nile crocs lurk unfound in the Everglades, but they aren't certain.

Allyson Gantt, a spokeswoman for Everglades National Park, where one of the reptiles was found, disagrees, saying no Nile crocs still roam the park.

Some Everglades visitors might not be aware of the differences between crocodiles and alligators, complicating efforts to confirm any remaining crocs. Crocodiles have angular snouts, and their lower teeth are exposed when their mouths are closed. Alligator snouts are rounded, with few exposed lower teeth. Nile crocs are usually bronze or brownish yellow; alligators are blackish green.

Wasilewsi said people are likely to notice the difference, or at least take photos that researchers can check later. And no, crocs and alligators can't interbreed.

Florida already has more non-native amphibians and reptiles than any region worldwide, according to the UF paper, published April 30 in Herpetological Conservation and Biology. They include Burmese pythons, a menace that quickly reproduced into the thousands and is decimating the Everglades' small mammal population.

Giant toads, iguanas and another species of crocodilian, the spectacled caiman, also live in the state. But that species grows to only about 80 pounds and feeds on fish, crustaceans and the occasional small mammals.

All three Nile crocodiles were captured in extreme South Florida.

— The first, a hatchling, was found on a front porch and sent to a Louisiana reptile exhibit.

— The second, a female measuring 4 feet, was captured at a park. Wasilewski kept it, but later gave it to another licensed researcher.

— The third was captured twice. The first trapper didn't have the proper permit, so he released the female. The croc was recaptured two years later 18 miles away by water in Everglades National Park. It was euthanized.

The UF paper said all Florida wetlands and coastal areas of Alabama, Mississippi, Louisiana and Texas would be hospitable to Nile crocodiles. They require fresh water, abundant prey and year-round warm weather.

"Doesn't that sound like Florida?" Krysko said.

Fortunately, Nile crocodiles don't reproduce rapidly. Still, the researchers said, it might only take one adult male and female finding each other for an Everglades population to become established.

"I have two words: Burmese python," Wasilewski said. "If you would have told me 15 years ago we would have an established population in the Everglades, I wouldn't have believed you."

Gator Mom vs. the World







Watch
how this protective alligator mother uses her "jaws of love" to protect
her newborns from the dangers that lurk in the Florida Everglades.
Link: https://youtu.be/IPTs2Nz3eA0





















Since today is Mother’s Day, here’s a look at the spectrum of
mother and offspring relationships on our planet. While humans are fond
of baby wraps, backpacks and strollers, other species have their own creative ways of transporting their young.
  • American alligator mothers often help their babies move around
    by letting them ride on their heads or sometimes even giving them a lift
    in their mouths.
  • Wolf spiders actually carry their egg sacs around with them and when
    the baby spiders hatch, they climb onto their mother’s abdomen for the
    first few days before heading off to live on their own. One Australian discovered this the hard way. [VIDEO]
  • This species of toad in South America embeds her fertilized eggs into her back. When they hatch, the tadpoles literally come out of her skin. [VIDEO]
  • Everyone’s favorite baby transporter, the kangaroo, has its famous stomach pouch, but I bet you didn’t know that baby kangaroos blindly crawl along their mother’s body from her uterus to the pouch right after birth. [VIDEO]
If that’s not enough of an animal fix for you, here’s a photo album from National Geographic of mothers and babies from across the animal kingdom.
And now for the rest of the week’s geek:

Hunters are killing huge Gators

Alabama hunters are killing huge gators off the Gulf Coast. 

Is that a good thing?

 
He was a whopper.

It took six men to pull a 13-foot, 9-inch alligator from Lake Eufaula in Alabama. The animal weighed in at 920 pounds at a local lumber yard in mid-August, but its girth is only now raising eyebrows and drawing gasps; it was weighed last week but started to draw national attention Tuesday.

The giant male gator is one of several monsters that were hauled out of waters during regulated hunts in Alabama, Texas and Florida in recent years, and some biologists question whether that’s a good thing
 
Big dominant males manage the habitat where they reside, keeping smaller, more aggressive males away.

“You move one animal and four or five or six smaller gators come in and fight for territory,” said Kent Vliet, an alligator biologist at the University of Florida.
. “It is a bit destabilizing in that sense.”
 
Vliet said alligator hunters should be encouraged to snag younger males to manage populations and leave the behemoths alone.

“In my mind, because so few alligators that hatch reach adult size, and even fewer reach full bull status, I think of those animals as being very valuable,” said Vliet, coordinator of the university’s laboratory in the biology department. “A lot of ecological resources have gone into making that animal. To me that’s sort of a waste.”


Humans don’t hunt that way.

[New study shows just what vicious predators humans really are]

They want the big game, the big trophy, a place in the record books. 
Scott Evans, of Center Point, and his friends, brothers Jeff and Justin Gregg, achieved that in some regard, capturing the biggest gator ever in that particular lake.

But as gators go, this beast was no state or national record. 
 
The largest alligator ever caught in the wild was a 15-foot, 9-inch giant wrangled last year in a tributary to the Alabama River.

More than likely, the world record 1,011-pound male would have dominated the more recent catch in Lake Eufaula. He probably wouldn’t have allowed him in his territory, and in the unlikely event that he did, he definitely wouldn’t have allowed him to approach females during the April to May breeding season, Vliet said.



The second largest catch, a 14-foot, 8-inch gator roped and drowned by Thomas Bass of Trinity, Tex., held the record until Mandy Stokes and a group of helpers made news with their catch last year. Bass caught his gator eight years ago, but wasn’t entered into the record kept by Safari Club International until last year.

Robert “Tres” Ammerman, a licensed practical nurse from Apopka, caught a skinny 14-foot, 3-inch male that weighed 654 pounds, in Lake Washington in 2010. It was the longest documented gator caught in Florida, according to the state Fish and Wildlife Conservation Commission.

Florida is renowned for alligators, which serve as the mascot for the state’s largest university, but the animals range the entire length of the Gulf Coast. They are also found in the Carolinas.


The American alligator is classified as threatened by the U.S. Fish and Wildlife Service, a listing that provides federal protection, But state approved management and control efforts are allowed under the designation.

Louisiana and Florida have the largest habitats, but the populations are rapidly growing in Alabama, Mississippi and Texas, Vliet said. With smaller habitats in the latter three states, population management programs were slower to start. 


[Frog, toad and amphibian populations are plummeting]

“Because they delayed the annual harvest for so long, they’ve had some very big animals,” Vliet said.
Removing them makes headlines, but the news is not always good, especially when no human has been harmed. “These are unusual animals. They have survived a long time. They tend to be wary animals. They may be older animals. It is likely that they do dominate an area, subordinate smaller males, mate with multiple females,” Vliet said.

“In a lot of ways they control the alligator population in that area. There’s no doubt in my mind that when you move an animal of this size, it has an impact on the population.”

Crocodile Threat



http://www.news.com.au/technology/science/northern-territory-crocodile-threat-revealed-at-inquest/story-fnjwkt0b-1227592870284?sv=7b0b16d80f70e292b02d5121461bbd6





Northern Territory crocodile threat revealed at inquest

CROCODILES in Northern Australia are getting bigger, are “showing no fear” of humans and are brazenly jumping at boats, according to inquest findings of two fatal attacks.
One case is believed to be the first time a crocodile has launched out of the water and killed someone on a boat, by taking him in his jaws.
The second involved a monster nicknamed ‘Michael Jackson’, who dragged a fisherman to his death by his outstretched arm. His wife gave traumatic evidence that he cried “Oh my god, I am dead” when he realised what was about to happen.
In the first attack examined by the inquest, 62-year-old Bill Scott was fishing with his wife Roslyn, son Aaron and friends on a Top End waterway in June 2014 when the unprecedented attack occurred.
Mr Scott was standing in his three-and-half-metre dinghy when a crocodile launched itself out of the water and locked its huge jaws around his left arm, shoulder and chest and dragged him into the water.
Mrs Scott was in the boat with him and told the inquest he had a “confused” look seconds before the attack — which is believed to be the first time a crocodile has attacked someone on a boat in the Territory.
The croc bumped into the boat first, causing Mr Scott to steady himself. But neither he or his wife could have predicted the horror that was about to unfold.
“This thing just came up from behind the motor and grabbed him And that was it,” Roslyn Scott said. “He was gone.”

She told the inquest the attack was so quick he couldn’t say anything and there was nothing they could do to help. There was no splashing, he simply disappeared with the crocodile into the murky brown water.
His body did float to the surface about 15 minutes later but it couldn’t be retrieved. Police and rangers later recovered his remains, counting an astonishing 23 crocodiles lurking nearby.
A large crocodile was shot the next day and its stomach was cut open. “Most of the deceased was located in the stomach of the crocodile, the only notable omissions being Bill’s left arm and clothing,” Gary Lindner, a veteran Kakadu Park Ranger, said in evidence.
The inquest, before Coroner Greg Cavanagh, also examined the death of a second fisherman, Lanh Van Tran, 57, who was attacked two months after Mr Scott on the banks of the Adelaide River.
Mr Van Tran saw his killer approaching but could do nothing to save himself.
He called out “Oh my god, I am dead” in Vietnamese just before he was dragged into the water by his left arm.
He had waded into three metres of mud that separated the water and riverbank to try and unsnag the fishing line when the crocodile struck.

His wife Thi Ban Le turned and saw a crocodile tail turn in the air. She ran to the water to help but could find no sign of her husband, having hoped to find him tangled with the fishing line.
She then drove to a nearby property to get help.
The croc that killed Mr Van Tran was later identified as one dubbed “Michael Jackson” — a big animal known in the area for its distinctive albino head and popular with tourists. Rangers caught it later that night with a spotlight with a hand and part of an arm in its mouth.
His left leg was found in its stomach with the rest of Mr van Tran’s body discovered nearby.
In his recently released findings, Coroner Greg Cavanagh said the sizes of crocodiles had continued to increase, as their numbers flourished since they become protected in 1971.
One theory advanced at the inquest, that was supported by rangers called to give evidence, was that the crocodiles were gorging themselves on the feral animals in Kakadu.
That meant the danger was greater now than ever.
“What is different from any other time is that since protection in 1971 crocodiles have become familiar with humans and boats and generally have not developed the fear of humans that once existed when humans were also predators.”
Because most tinnies were about 3.5m they run the risk of “being dwarfed” by the larger crocodiles.
“The circumstances of the death of Mr Scott are a reminder that the risks of being taken from a boat by a crocodile have also increased.”

Mr Scott’s death was likely to be the first from a boat although there had been at least one attempt before. In that case, Jeff Bolitho told of being knocked over on his boat by a 4m crocodile however he wasn’t dragged away.
“The next night the Rangers re-enacted the scene and a 4 metre crocodile came straight up the river to their boat. It showed no fear. They harpooned it,” the coroner said.
During the inquest three rangers — Garry Lindner, Calvin Murakami and Fred Hunter — gave evidence of dealing with crocodiles in the Northern Territory.
Their evidence could be summarised as; a big crocodile is a smart crocodile; if there are crocodiles in the area you will be observed by them (even if you can’t see them), and many crocodiles no longer see humans as a threat;
“The simple fact is that crocodiles are able to propel themselves from the water to take hold of their prey. Where that is from the water’s edge on land the dangers are relatively well known. However the dangers when in a boat seem not to have been well recognised as similar.”
The Parks and Wildlife Commission of the Northern Territory (PWCNT) has recorded instances of crocodiles “launching at, nudging, banging, and in some instances, biting at boats.”
The inquest heard that some waterway users were already putting safety railings on their boats before Mr Scott’s death. The process has sped up since then, including on vessels belonging to the water police who described the death as a “wake up call”.
Mr Cavanagh recommended warnings should now include the message “saltwater crocodiles can attack people in boats and the smaller the boat the greater the risk”.
He recommended PWCNT consider a greater emphasis on the hidden dangers, as both Mr Scott and Mr Van Tran had been killed by lurking crocodiles,
According to the ABC, PWCNT chief executive Andrew Bridges responded to the findings by agreeing there could be more emphasis on the hidden dangers.
He said the PWCNT would act on the findings, including to inform the public of the importance of the stability and the size of a boat.
