The squirrel, master in the art of stock management?

by Yohan Residence 2 November 2017,

According to an American study, this small animal organizes its food reserves by categories of food, as we do at home for our fridge and other closets.

Squirrels are animals that love nuts such as almonds, nuts, hazelnuts and other oilseeds. They are particularly known for their ability, not to say their relentlessness, to make provisions to spend the winter without worries of supply.

Mikel Delgado and Lucia Jacobs from the Department of Psychology at the University of California, Berkeley, USA, studied the behavior of the wild squirrel (Sciurus niger), a very common species in North America. For two years, the duo of scientists proposed different provisions to a range of 45 squirrels. The provisions were given to them sorted by varieties (ex: 4 or 5 nuts), or mixed (ex: 1 hazel nut, 1 almond, 1 nuts ...).

You should know that squirrels can store each year near 10 000 nuts and more! The results published in the journal Royal Society Open Science 10 August 2017 (PDF in English / 6 pages) demonstrate that these animals are careful to carefully sort their provisions according to the variety and placing them in different hiding places, probably to to find one's way better This is not a coincidence when one considers such a large number of commodities.

"We know that rats, monkeys, or pigeons use this technique of" chunking ", but this is the first time we see it in a species that disperses its food in hiding places. The idea is that by using this method, the squirrel decreases the amount of information it needs to remember and it allows it to better memorize it, "says Mikel Delgado.

Without a doubt, the squirrel is an expert in stock management and its organizational capacity is undoubtedly one of the most powerful of the animal kind!

Macaque monkeys also use dental wires to clean their teeth

by Brice Louvet 18 November 2017

The ability of some monkeys to use tools to feed themselves was already known. But the observation of nature in this area still has some surprises. Some were surprised to clean their teeth after a good meal, improvising floss.

How do some reptiles react to freezing temperatures? Alligators from North Carolina have demonstrated a particularly interesting prehistoric method.


George Howard's 12 alligators, a shrine owner, went to his marsh when temperatures dropped after the "weather bomb" last week. The temperature of the water was then higher than that outside.

VIDEO. A diver protected by a whale

Published on Sunday 14 January 2018

The marine biologist Nan Hauser probably had the fright of his life. While swimming near the Cook Islands in the South Pacific, a shark approached her. The humpback whale she was filming then hid it under her fin.

Image


Marine biologist Nan Hauser was frightened by a dive into the waters of the Pacific Ocean off the Cook Islands. The diver was filming a humpback whale when the behavior of the whale changed. The cetacean approached her, then pushed him. Only later did she realize that the animal was trying to protect it from a shark by "hiding" it with its tail and its fin.


Nan Hauser, who has been swimming with whales for 28 years, told his story to the British newspaper The Independent. She explains that she has never lived such a moment. "I was not sure what the whale was doing when she approached me, and it kept pushing me for more than 10 minutes. It seemed like hours. "


The biologist tried not to panic despite the unusual behavior of the animal. "I tried to get away for fear that [this male] would hit me hard or hit me with his fins or tail, it would break my bones and break my organs," she says. he had kept me under his pectoral fin, I would have drowned. "

If Nan Hauser explains that she has already heard of the altruistic behavior of humpback whales, this is the first time she has seen it with humans.

THE STAR OF THE ZOO: IT'S HIM! 15 Jan 2018 The first baby panda born in France, Yuan Meng, realized, five months after being born, his first public outing to the Beauval Zoo in the Loir-et-Cher where the public came in number for the admire. Yuan Meng, "fulfillment of a dream", with gray and pinkish white fur, appeared beside her mother, in her pen. This panda was the first to be born in France thanks to the loan of his parents, in 2012 for 10 years, by China.

Reading a bit about the lemurs of Madagascar I find:

While visiting (in 2015) in Marlow Park, in the north-east of Germany, Angela Merkel was able to feed a lemur on her shoulder. A moment that the Chancellor has seemed very funny. She was in the park to inaugurate a new area dedicated to penguins.

Extreme video: the penguin falls but is unbreakable!

It slips on the plates of ice, falls from the top of the rocks, falls in icy water, lands on its congeners ... On the coasts, the penguin knows many bowls, but almost always stands up without a scratch! The animal is robust and perfectly adapted to its environment, quite hostile to humans. Here is the video proof.

The penguins are perfectly adapted to their extreme environment, even if they sometimes look somewhat awkward. With wings that no longer allow them to fly, these birds are more marine than terrestrial, and sometimes have some difficulties to move on the continent. Although in southern waters they are amazing divers, these few images give meaning to their appointment as "penguin". Full of humor, here is a compilation of the most beautiful penguin falls filmed during the realization of the Waddle All the Way project.
..............

In this compilation, the birds of the southern waters seem clumsy. Yet not one of these falls is fatal: the bird falls, but is almost always recovering as quickly. It must be recognized that these animals are excellently adapted to harsh southern conditions. The three species are great divers. The emperor penguin is the best, able to dive deeper than 300 m and go up in minutes to the surface. His bones are extremely strong and can withstand 40 times the atmospheric pressure. Other birds (or humans) would suffer terrible barotrauma for the same type of diving. A small fall, as in the video, seems derisory.
