Banff National Park
This park is known for its rugged mountain scenery,
glacier-fed turquoise lakes and miles of untouched forests. Perfect for
hiking in summer and skiing in winter. Thrill seekers will find no
shortage of activities, from white water rafting to mountain biking. The
park’s lakes are a gorgeous aqua-blue color in summer and their
surfaces reflect the surrounding mountains. Hike the hills above Peyto
Lake and Moraine Lake for two of the most photographed scenes in Canada.
Lake Minnewanka isn’t fed by glaciers, but it’s one of only two lakes
in the area that allows boats on the water.
Helmcken Falls,British Columbia
Helmcken Falls is a 141 m (463 ft) waterfall on the
Murtle River within Wells Gray Provincial Park in British Columbia,
Canada. The protection of Helmcken Falls was one of the reasons for the
creation of Wells Gray Provincial Park in 1939. Helmcken Falls is the
fourth highest waterfall in Canada, measured by total straight drop
without a break.

Weird “dinobat” Discovered in China
A strange new dinosaur with
bat-like wings has been discovered by a farmer in China and is now helping to
shed new light on the evolution of flight. Paleontologists in China say the
impeccably preserved fossil belongs to a small dinosaur thought to have lived
160 million years ago. The bizarre looking creature had slight stiff feathers
on its body and long finger-like bones extending from each wrist that were
covered in a membrane like a bat’s wing. Further, Dinosaur with wings like a
BAT may reveal clues about the origin of flight, it’s named Yi qi is thought to
have lived 160 million years ago during the late Jurassic.
The dinosaur has an
unusual bone sticking out of its wrist and had a membrane that covered it to
form a wing much like that of a modern bat. Researchers say it is unlike any
other dinosaur, which evolved into birds, and may have glided or even been able
to fly by flapping over short distances. Therefore, the fossil was discovered
by a local farmer in Qinglong County in north China. Researchers say the
dinosaur, which would have weighted just 13 ounces and was 33cm long with wings
that spanned 60cm, may have been an early evolutionary research with flight. Yi
qi belong to the group of carnivorous dinosaurs recognized as the therapods which
includes Tyranosaurus rex and velociraptor. Therefore, these dinosaurs are
thought to have been the ancestors of modern birds. But unlike modern birds, Yi
qi was found to have a strange extra bone extending backwards from its wrist,
rather like an entirely separate group of animals that learned to fly the bats.
Professor Xing Xu, one of the world’s foremost prolific paleontologists at the
Chinese Academy of Sciences in Beijing and who led this work, said: This is actually
something for me and it is the most unexpected discovery I ever made.
Moreover, birds are descended
from dinosaurs, but how accurately the transition occurred is not really clear.
This fresh discovery is a new species of these birds like dinosaurs. This
dinosaur is completely different, and it has completely different wings from
all other birds and their close relatives. Furthermore, close to the origin of
birds there are numerous lineages trying to get into the air but there was only
one group that succeeded. It’d have said this example shows how much experimentation
close to this transition. The discovery comes in the same week as researchers
announced the discovery of a bizarre vegetarian relative of the T-Rex.
The Yi qi fossil was discovered
by a local farmer in Mutoudeng, in Qinglong County, Hebei Province in China. The
fossil has preserved stiff filamentous features on the forelimb and hind-limb,
along with patches of the membrane that once stretched across its wings. However,
it was the strange wrists and long rod-like bones that extended from them that
baffled the attention of the paleontologists. There are three main groups of
flying vertebrates - the birds, which evolved from dinosaurs, pterosaurs that
were flying reptiles that existed alongside the dinosaurs, and the bats, which
are mammals that evolved after the extinction of the dinosaurs 66 million years
ago.
Most winged avian dinosaurs to be
discovered so far all have wing structures that are similar to those of modern
birds. However, Yi qi, which is pronounced “ee chee”, appears to be a strange
hybrid between a dinosaur and a bat. This has also suggests that at the time numerous
different types of winged dinosaurs evolved wings in an attempt to fly. This has analysis by Professor Xu and his coworkers,
which is published in the journal Nature, proposes that it is likely that, the
dinosaur glided, perhaps like modern flying squirrels. The dinosaur lacked the
strong muscle attachments to the forelimb bones and its bone structure would
have interfered with the flapping and rotating movements needed during powered
flight. Instead it may have launched itself from elevated perches and glided to
the ground. If it did flap its wings it would probably have only been able to
fly over short distances.
But Professor Xu said: “We
thought giving this animal a name meaning "strange wing" was
appropriate, because no other bird or dinosaur has a wing of the same kind. We
don’t know if Yi qi was flapping, or gliding, or both, but it definitely
evolved a wing that is unique in the context of the transition from dinosaurs
to birds. It is likely that the conclusions will be controversial with other
evolutionary biologists, but it could prove hugely valuable in unravelling how
birds evolved from their dinosaur ancestors. Professor Zheng Xiaoting, from
Linyi University in Shandong who also took part in the study, said: Yi qi lived
in the Jurassic, so it was a pioneer in the evolution of flight on the line to
birds. Thus, it reminds us that the early history of flight was full of
innovations, not all of which survived.
Dr Kevin Padian, a paleontologist
at the University of California Berkeley, warned that the animal may not have
been able to fly at all. The fossil of Yi qi was discovered by a farmer working
his fields in Mutoudeng in Qinglong County in China, He also said: As for
gliding, if Yi qi’s styli-form element helped to support a membranous aero-foil,
it can be used to rebuild the planform of the wing, as Xu and colleagues have
done. But in a gliding animal, the center of lift of the aero-foil should be
fairly congruent with the center of gravity of the body if the bulk of the
animal’s weight falls too far behind the center of lift, the back end will sag
and the animal will stall.
That is clearly the case in the
authors’ reconstruction of Yi qi, but an aero-foil that was swept back more, if
anatomically possible, might have mitigated this problem. Still, we’re left in
a quandary; an animal with a bizarre structure that looks as if it could have
been used in flight, borne by an animal that otherwise shows no such
tendencies. And so far, there’s no other plausible explanation for the function
of this structure.Source: Dailymail

The Mysterious Libyan Desert Glass
The Mysterious Libyan Desert Glass can be found between the borders of Egypt and Libya. It is called Great Sand Sea, which is a massive sandy desert that is spread more than 650 kilometers from north to south and around 300 km from east to west, covering an area of even the size of Ireland. Therefore predominant winds have organized this great sand mass into enormous longitudinal crested dunes rising 100 meters high at places and stretching uninterrupted for hundreds of kilometers. It is separated by flat corridors about a kilometer or two wide.
In these stretched narrow gaps are areas where the underlying bedrock is visible. In these visible surfaces an inquisitive natural glass is found. Therefore the so called Libyan Desert Glass is the cleanest natural silica glass ever found on planet earth. The captivating glass is usually yellow in color. Though, it can be very clear or it can be a milky, and even comprise minute bubbles, white wisps, and inky black swirls. Thus, more than thousand tons of these glasses are strewn across hundreds of kilometers of bleak desert. Most of these are the size of pebbles polished smooth by the abrasive action of the blowing sand. However others are chunks of substantial size and weight. So far, the biggest piece ever found weighed about 26 kg.
Well, the natural glass, such as “Libyan Desert Glass”, can be molded either by lightning strike, or volcanic activity or meteorites striking the earth. The Libyan desert glass has been dated as having formed about 26 million years ago, which made researchers assume that the glass here was formed when a meteorite struck earth around this time, but the absence of an impact crater create problems for this theory. As a result in 2007, a circular feature was discovered using satellite pictures but proof of it being an impact crater is slim to none.

Furthermore another theory recommend an exploding comet near the surface heating up the sand beneath it to an intense temperatures resulting in the formation of a gigantic amount of silica glass. The first scientific discovery of “Libyan Desert Glass” was prepared by an Englishman named “Patrick A. Clayton” in 1932, who brought the first glass samples back to Europe for research. Nevertheless, the existence of the glass was well-known to man long before that. The local natives in the Neolithic period made tools out of the glass, and later the Egyptians used it in making jewel. A large piece of carved stone on the breastplate of the famed Egyptian pharaoh Tutankhamun was identified as none other than Libyan Desert Glass.
The Striking Scissor-Tailed Flycatcher is Only Regular “Long-Tailed Kingbird”.
The
striking scissor-tailed flycatcher is our only regular “long-tailed kingbird.”
But it is not only elegant and attractive, but also common and easy to
observe. The splendid scissor-tailed
flycatcher (Tyrannus forficatus), also recognized as the Texas bird-of-paradise
and swallow-tailed flycatcher, is a long-tailed bird of the genus Tyrannus,
whose members are collectively referred to as kingbirds. Well, the kingbirds
are a group of large insectivorous (means insect-eating) birds in the tyrant
flycatcher (Tyrannidae) family. The scissor-tailed flycatcher can be found in
North and Central America. This bird was also famous with its former Latin name
“Muscivora forficate”. The former genus word, “Muscivora” actually derives from
the Latin word for "fly" (musca) and "to devour" (vorare),
while the species name forficata derives from the Latin word for
"scissors" (forfex). The long scissortail bird is now considered to
be a member of the Tyrannus, or "tyrant-like" genus. This genus
earned its name because quite a few of its species are exceptionally aggressive
on their breeding territories, where they will feel no hesitation to attack on
larger birds such as crows, hawks and owls.
Moreover,
adult birds have pale gray heads and their upper parts, light underparts,
salmon-pink flanks and under tail coverts, and dark gray wings. Axillars and
patch on underwing coverts are red. The bird’s species extremely long, forked
tails, which are usually black on top and white on the underside, are
characteristic and unique. At maturity, the male may be up to 15 inches in
length, though the female's tail is up to 30 percent shorter. The wingspan is
15 cm and the weight is up to 43 g. Further, Lmmature birds are duller in color
and have shorter tails, whereas a lot of these birds have been reported to be
more than 40 cm. The male and
female travel together throughout their territory in search of a nest place in
open prairie, mesquite prairie, parks, gardens, pastures, croplands, roadsides
or saltmarsh edges. When they discover a potential nest site in an isolated
tree or shrub, they both hop around and test out diverse spots by pressing
themselves against the branches. They normally select an open site that’s
sheltered from the prevailing wind and often shaded by some foliage. These birds build a cup nest in isolated trees or shrubs, sometimes
using artificial sites such as telephone poles near towns. The male bird
performs a huge aerial display during courtship with his long tail forks streaming
out behind him. Both species feed the young bird and like other kingbirds,
they’re extremely aggressive in defending their nest. Normally these birds’
clutches contain 3 to 6 eggs.
In the
summer season, scissor-tailed flycatchers feed mostly on insects i.e., grasshoppers,
robber-flies, and dragonflies, which they may catch by waiting on a perch and
then flying out to catch them in flight. If they need extra food in the winter
season, they’ll also eat some berries. The bird breeding habitat normally in open
shrubby country with scattered trees in the south-central states of Texas,
Oklahoma, Kansas; western portions of Louisiana, Arkansas, and Missouri; far
eastern New Mexico; and northeastern Mexico. It is reported sightings record
occasional stray visitors as far north as southern Canada and as far east as
Florida and Georgia. The birds migrate through Texas and eastern Mexico to
their winter non-breeding range, from southern Mexico to Panama. Moreover, pre-migratory
roosts and flocks flying south may comprise as many as 1000 birds. The lovely
scissor-tailed flycatcher is the state bird of Oklahoma, and is displayed in
flight with tail feathers spread on the reverse of the Oklahoma Commemorative
Quarter. The Scissor-Tailed Flycatchers have the habits of having several human
products in its nest, such as string, cloth, paper, carpet fuzz, and cigarette
filters. Well, this beautiful Scissor-tailed Flycatcher numbers are a small
decline between 1966 and 2010, however, according to the North American Breeding
Bird Survey. A decline was noted in the mid-1970s, which was offset by an
increase in numbers during the 1980s. Moreover partners in Flight estimates a
global breeding population of 9.5 million with 92 % breeding in the United
States., and 50 % spending some part of the year in Mexico.

Scientist Discovered Species Looks Exactly Like Kermit the Frog
Down in Costa Rica, researchers
have discovered an attractive, acquainted looking new species. This transparent
newfound amphibian is a frog identified as Diane’s Bare-hearted Glassfrog,
since its underbelly is translucent and takes on the appearance of glass. Most
astonishingly, this strange creature looks just like Kermit the Frog! The frog has evaded discovery until now
because it lives in an isolated location and also because it’s mating call is
quite akin to an insect's call. Brian Kubicki, Stanley Salazar, and Robert
Puschendorf are the inventors who discovered this beautiful Kermit look-alike
between 400m and 800m up in the Talamanca Mountains, stating that its call
sounds like “a single tonal long metallic whistle-like note.” Not only did Dr.
Kubicki able to capture some vivid photos of the frog, he also decided to name
it after his mom Janet Diana Kubicki, according to the Costa Rican Amphibian
Research Center. Source: My Modernmet
