Peninsula Valdes in Argentine Patagonia – Killer whales Season – Fall 2017

Peninsula Valdes - Orca Season - Fall 2017

Killer whales is a beautiful spectacle in the province of Chubut and is already in full swing the first season of the year. In patagonia are 2 seasons of killer whales throughout the year; One between March and April in Punta Norte and the other between October and November in Caleta Valdés.

The 7 Loudest Animals in the World

Boatman

Engineers and evolutionary biologists in Scotland and France recorded the boatman—which is roughly the size of a grain of rice—”singing” in a tank. The aquatic insect’s songs peaked at 105 decibels, roughly equivalent to the volume of a pounding jackhammer within arm’s reach.

The chirps are loud enough that humans can hear the sounds while standing at the edge of a boatman’s pond. Fortunately for nature lovers, though, nearly all the sound is lost when the noises cross from water to air.

Remarkably, the boatman creates his songs by rubbing his penis against his belly, in a process similar to how crickets chirp. Sound-producing genitalia are relatively rare within the animal kingdom, but animals have evolved hundreds of other ways to boost their hoots, howls, and snaps.

Did you ever read about loudest animals of the world? Well, we have selected an article from Nat Geo containing a list of world’s loudest animals.

The Howler Monkey

The howler monkey is the loudest land animal. Its calls, which some say are actually more like growls, can be heard up to three miles (five kilometers) away.

The monkey’s volume comes from its enlarged hyoid bone, a U-shaped bone in the howler’s throat that “isn’t actually hooked to any of the [other] bones, so it kind of just hangs there,” said Dell Guglielmo, caretaker for two howler monkeys at the National Zoo in Washington, D.C. The enlarged bone creates a throat sac in which the monkey’s calls resonate before booming out.

Coqui Frog

Only the males of the common coqui frog sing, but their calls, recorded at peaks of a hundred decibels from three feet (a meter) away, make them the loudest known amphibians.

The nocturnal frog’s two-part “co-qui” call has a two-part meaning: Other male frogs respond to the territorial “co” part of the call, while females are attracted to the “qui.”

In the coqui’s native habitat of Puerto Rico, the frogs are considered part of the island’s natural heritage. But in Hawaii, where the frogs are quickly establishing themselves as an invasive species, residents have spent many sleepless nights due to the noisy frogs, which, in aggregate, are comparable to a lawnmower running all night.

The Blue Whale

The blue whale is the loudest mammal of them all, with vocalizations that reach 188 decibels.

Blue whales don’t have songs as complex as those of humpback whales, but their low-frequency “pulses”— some below the range of human hearing—have been recorded more than 500 miles (805 kilometers) away.

A few years ago researchers found that the whales had been lowering the frequencies of their songs even more—by up to 30 percent since the 1960s in some populations. One theory suggests that the whales no longer need to sing at “high” pitches to be heard at a distance, because the species, while still endangered, has rebounded since whale hunting was banned in 1966.

The Snapping Shrimp

The snapping shrimp doesn’t sing, chirp, wail, or hoot, but it just might be responsible for the loudest noise produced by any living being.

These shrimp stun prey by closing their specialized claws quickly enough to shoot jets of water out at 62 miles (100 kilometers) an hour, forming a low-pressure bubble of vapor behind the jet. When that bubble collapses, it produces a hot, loud mini-explosion of 200 decibels, which stuns or even kills the shrimp’s dinner.

The Oilbirds

You wouldn’t want to be around when oilbirds come home to roost—these cave dwellers, the loudest known birds, can be deafening when gathered in large groups.

Oilbirds use echolocation to navigate in completely dark caves. But, unlike the calls of most bats, the birdcalls are within the range of human hearing. Each bird can produce squawks and clicks up to a hundred decibels at close range, and colonies can contain thousands of birds.

The oilbirds appear to use echolocation only within their cave homes and not during their nocturnal foraging. This could be because their sensitivity isn’t very high: In one experiment, oilbirds flew straight into plastic discs that were 4 inches (10 centimeters) wide, but they were able to avoid 8-inch (20-centimeter) disks and larger.

The Mole Cricket

The mole cricket species Gryllotalpa vinae is the loudest of the insects. The critter uses its specialized front legs to dig a megaphone-shaped burrow. Standing inside that dugout, a cricket can chirp loudly enough that humans can hear it nearly 2,000 feet (600 meters) away.

Microphones placed three feet (a meter) from a cricket’s burrow entrance have recorded peak sound levels of 92 decibels, or about the volume of a lawn mower.

In fact, using the burrow, G. vinae is able to turn an astonishing 30 percent of its energy into sound.

“Whoever said you can’t buy happiness forgot little puppies.”  ~ Gene Hill

It´s always a joy to watch puppies at play.   Puppies are so cute, especially when they are clumsy, awkward and fall asleep in the middle of doing something!  It´s great to see their little personalities coming out.

DELIGHTFUL!

Orcas in Peninsula Valdes, Argentina

At this time of year come Orcas in Peninsula Valdez.
I had the opportunity to visit Puerto Madryn and the surrounding area, and is a lovely place.

The author of this video is Charly.
Who knew in the summer. A cameraman and photographer, who is an expert on the fauna and geography of the Peninsula Valdez.

Intentional Stranding technique to capture sea lion pups. Valdes Peninsula in Chubut Province, Argentina, is the only place in the world where this behavior can be observed annually.

Flamingo in El Calafate

Flamingos are very social birds that live in colonies that can number in the thousands, so we know in large lake Africa or America.

However, in Calafate colonies can not be counted by thousands but by tens.

But the colors stand out against the gray of the mountains, the sky blue and dark blue of the lake.

Obviously, it is to make two thousand miles to see Flamengo. But for deternse and see … may be wondering how these birds with their feet stuck in the cold waters of Lake Argentino. And while you can enjoy some good mates on the shores of the lake (recommended for tourists: Try the Mate!).

In the summer of 1911, a group of Australian scientists, adventurers and explorers set out to make history by undertaking the first Australian expedition to Antarctica, a three-year journey into the frozen unknown. Under the leadership of Dr. Douglas Mawson, they set sail for Macquarie Island and the virgin parts of Antarctica. Today, we look at what they encountered and recorded on the way not merely as a rare and fascinating glimpse of long-gone world frozen in time, but also as the source of important information that made a major contribution to how contemporary science understands the region and laid the groundwork for claims that in 1936 were formalized as the Australian Antarctic Territory.
Here are some pictures of James Francis (Frank) Hurley, the officialphotographer to the Australasian Antarctic Expedition, and Other member.

Kamchatka contains probably the world’s greatest diversity of salmonid fish, including all six species of anadromous Pacific salmon (chinook, chum, coho, seema, pink, and sockeye). Biologists estimate that a sixth to a quarter of all Pacific salmon originates in Kamchatka. Kuril Lake is recognized as the biggest spawning-ground for sockeye in Eurasia. In response to pressure from poaching and to worldwide decreases in salmon stocks, some 24,000 square kilometers (9,300 sq mi) along nine of the more productive salmon rivers are in the process of being set aside as a nature preserve.
