Very scenic and feast to the eyes. Maligne Lake in Jasper National Park. Canada
Very scenic and feast to the eyes. Maligne Lake in Jasper National Park Canada. It
is a visual feast. Something which is unimaginable. No photograph or
video can capture its beauty . One has to see with their own eyes. The
boat ride gives an opportunity to see the beauty of the lake with
surrounding mountains from different angles. It is one place to visit in
ones life time and a boat ride which one has to take and experience. The
water of Maligne Lake is a beautiful shade of green, almost tropical in
color. The mountain views are amazing for sure!!! Spirit Island is
actually a small peninsula surrounded by the green waters of the lake
and the Rockie Mountains. There are plenty of places to stop where
you can see wildlife in abundance and take stunning photos. You get to
leave the boat briefly at Spirit Island where you can take a short walk
before returning to the boat. It is also an area where you can hire
canoes and kayaks or just walk.

Felis Lynx
The lynx is a member of the cat family and one of the
bigger felines of North America. Lynx are best known for their short
stubby tails and the long tufts of black hair on the ears of a lynx. There
are three different types of lynx with these being the North America
lynx found in Canada and Alaska, the European lynx found in Spain and
Portugal and the Asian lynx which is found in Turkestan and central
Asia. The North American lynx is the biggest species of lynx and
some of these lynx individuals have extremely thick and fluffy looking
fur which keeps the lynx warm in the freezing Canadian winter. The
European and Asian lynx species are much smaller in size and have
personalities that resemble those of a domestic cat, rather than a large
feline.
The lynx tends to inhabit dense shrub and grasslands in the forests of North America and parts of Eurasia. The lynx hunt small mammals, birds and fish, and the lynx are prey to few predators. Although the lynx is a ground mammal, lynx are often known to climb trees or swim in order to catch their prey. Lynx hunt small mammals, birds and fish but prefer to hunt larger mammals like reindeer, deer and elk if the lynx can find and catch them. The lynx has large paws which help the lynx to balance and also give the lynx more power when pursuing potential meals. The lynx also has extremely acute hearing which allows the lynx to hear oncoming prey and predators over long distances, and the lynx also has a strong jaw and sharp teeth which the lynx uses to bite down on its prey.
Lynx are usually solitary animals and will spend their time both hunting and resting alone, however a small group of lynx may travel and hunt together occasionally. Lynx mating takes place in the late winter and the female lynx will give birth to two to six kittens after a gestation period of about 70 days. Female lynx will usually give birth to a litter a year. The young lynx kittens stay with the mother lynx for around nine months meaning that the lynx kittens will have the mother lynx to watch over them during their first winter. The lynx kittens then move out to live on their own as young adults. It is known that adult lynx will give their young the prey to play with it before they eat it as this thought to develop their hunting skills. Lynx live in dens in rock crevices or under ledges which gives the lynx a safe place to rest as well as a home for when the lynx kittens arrive and need safely looking after. Lynx do not normally take their kill back to their den, the main exception to this is when the mother lynx is providing for her lynx kittens. Lynx children love to wrestle with each other.

The Cascadas de Agua Azul (Spanish for "Blue-water Falls")
The Cascadas de Agua Azul (Spanish for "Blue-water
Falls") are found in the Mexican state of Chiapas. They are located in
the Municipality of Tumbalá, 69 kilometers from Palenque by the road
that leads towards San Cristóbal de las Casas. This waterfall
consists of many cataracts following one after another as can be seen in
the first photo in the picture gallery, taken from near the top of the
sequence of cascades. The larger cataracts may be as high as 6 meters
(20 feet) or so. The one pictured to the right is next to the bottom of
the sequence.
Waterfalls Lakes Plitvice, Croatia (National Park)
Waterfalls Lakes Plitvice, Croatia (National Park) is
among the 20 most beautiful lakes in the world to 17th place. The park
covers an area of 33,000 hectares and includes 16 lakes in succession,
connected by waterfalls.Plitvice is the oldest national park in
Southeast Europa.All'interno the park there are also many caves of which
only a small part is agibile.I lakes are formed by two rivers: the
White River and the Black River, which flow in the river Korana. The
waters of these rivers are rich in calcareous salts (mostly calcium
carbonate and magnesium carbonate), from the dissolution of carbonate
rocks forming the geological structure of sito.Questi salts are
precipitated by vegetation, forming layers of travertine , a sedimentary
rock recently. Over time, these deposits forming real natural dams that
act as barriers to water, growing by about a centimeter per year. At
one point the water pressure breaks these natural levees, opening new
paths in the ground. This mechanism, in fact common to all the calcareous water, in Plitvice has assumed a particular importance.The beauty of the National Park Plitvice, Croatia, is increased in the second round of the New Seven Wonders of Nature.

The Amazing Colors of Malayan Banded Pitta
This is one of
three separate species of banded pittas that were lumped together as one. Due
to their vocal and visual differences the species were in recent times split. The
Malayan banded pitta (Hydrornis irena) is a species of bird in the Pittidae
family. The bird can be found in Thailand, the Malay Peninsula and Sumatra. It
was previously considered conspecific with the Bornean and Javan banded pittas.
Together, they were referenced as the banded, but this is recently split
species is listed as near threatened on the basis that the constant destruction
of its habitats and capture for the illegal bird trade are suspected to be
driving a moderately rapid decline in its population. More research is needed
into the impact of these threats, the results of which could influence its Red
List status. 20-23 cm.
Moreover, the gorgeous
and amazingly colored Pitta species male has black crown and broad mask, with wide
bright yellow supercilium, becoming flame orange on the nape. The underparts
are deep blue, save for orange barring on the breast sides. Moreover upperparts
plain chestnut-brown; rump and tail deep blue. The beautiful wings are blackish-brown
with a white spot in the primaries and some white in the outer secondary’s. The
median and greater coverts are broadly tipped white. The chin and throat are
also white. However, female birds are similar except for white underparts with
fine black barring, and juveniles and immature have bold, pure white spotting
on the upper wing coverts. It is called as locally common, though now infrequent
in Thailand and decidedly local in Sumatra, though the population size has not
been quantified and further research is required.
The species’
population is suspected to be undergoing a reasonably rapid decline owing
primarily to on-going deforestation and hunting for trade. The species inhabits
lowland floodplain forest, but is also found at higher elevations, maybe up to
c.1,500 m. Indeed, it appears to depend on to a large extent on lowland
evergreen forest and swamp forest. It favors the interior of primary forest,
but is also found in secondary forest, although observations recommend that it
does not persevere well in altered habitats. Its diet perhaps comprises
invertebrates and berries, which it forages for on the ground and in understory
vegetation. Breeding probably takes place throughout the year.
In spite of some
apparent tolerance of habitat alteration, it is threatened by forest loss and
degradation, apparently driven by timber extraction and agricultural expansion,
as well as capture for the illegal bird trade either through trapping or
nest-raiding. The bird is now considered rare in Thailand, where the majority
lowland forest has been logged. Moreover, a same situation is existing in
Malaysia, where the bird has been almost disappeared from Panti Forest Reserve
since 1994. The species come about in a number of protected areas across its outsized
range, including Khao Nor Chuchi Wildlife Sanctuary (Thailand), Taman Negara
National Park (Malaysia) and Way Kambas National Park (Sumatra). No other
targeted conservation actions are recognized for this species.

Mysterious “Pyramid” spotted on Ceres
The latest photographs of Ceres
taken by the Dawn spacecraft have captured an enthralling pyramid-shaped
mountain on the surface in its second mapping orbit, from a height of 2,700
miles. As the spacecraft gets closer, more and more features are beginning to
reveal themselves, as mysterious lone mountain discovered towering over the
surface of the dwarf planet. The mysterious bright spots appear now as an array
of dots scattered across the floor of a crater however their source remains unidentified.
Though, six months ago, Ceres appeared as nothing more than a few pixels of
light to Dawn, but now it is nearing its closest orbit to the increasingly fascinating
dwarf planet. At the end of Dec 2015, the spacecraft will be just 225 miles above
the surface and lower than the International Space Station is above Earth.
Scientists
must make do with these tantalizing glimpses of the features that are waiting
on the surface. Hence, in one photograph, a pyramid-shaped peak is seen
towering over a relatively flat surface. This is very Peculiar Mountain, as
there’re few other important features like it in the surrounding again or even
the rest of the dwarf planet. However, the structure is believed to rise about 3
miles, almost equal to the height of Mont Blanc in France and Italy, the
highest mountain in the Alps. Moreover, in another photo reveals the bright spots
in greater detail. More than a few can be seen next to the largest bright area,
projected to be six miles wide. Nevertheless the ice and salt are the leading
theories for what is causing this odd reflectivity.
Dr Marc Rayman, Dawn’s mission director
and chief engineer says; it is really exciting to seeing these features come
into sharper focus, as few months ago, when Dawn starts observing its new home
from afar, we called it a bright spot. As the explorer closed in and provided
better views, we realized it was two bright spots. Now we see these are in many
numbers and it’s still not clear what is causing these strong reflections, and
I think still more data are required. However, everyone has their own personal
favorite theory, but the eventual arbiter is nature. That is, we can all
speculate, and we can offer arguments, but the answer is going to be clear
soon. Well, my money is on the remnants from ice that has sublimated, and the
salts left behind then could be what are reflecting the light. Other photographs
disclose the multitude of craters and lines strewn across the surface of this
world, situated in the asteroid belt between Mars and Jupiter. Because there’s
also evidence for past activity on the surface, including flows, landslides and
collapsed natural structures.
Though, Ceres appears to have
more remnants of activity than the proto-planet Vesta, which the Dawn
spacecraft already studied for 14 months in 2011 and 2012. Therefore, Dawn,
which arrived at Ceres on 6th March 2015, is the first spacecraft to orbit two
separate bodies in the solar system. It will remain in its current orbit until
30 June, before moving to a lower altitude of 900 miles by early August. Numerous theories are presently being touted
for what the mysterious bright white spots are on Ceres. The Hubble Space
Telescope has found over 10 on the surface, but Ceres has found that the two
most noticeable - ‘spot 5’ - are in a crater about 57 miles wide.
Moreover, another theory is that
they’re salt flats that are reflecting sunlight, left on the surface by
saltwater or by other chemical reactions. One more theory is that they’re
regions of ice, again reflecting sunlight. It is thought, that Ceres is having
plenty of ice beneath its surface, which could be uncovered when an asteroid or
comet strikes the surface. The fact these bright spots are in a crater where
such an impact occurred actually supports this theory. Therefore, another
possibility is that they’re cryovolcanoes - volcanoes that are shooting out
water or ice.
Though, the lack of a raised area around the spots steady with a
volcano suggests this might not be correct. And they could even be water vapors
ejecting from a liquid reservoir under the ground, though again present
observations - namely a lack of extra material close the spots suggests this is
not the case. The surface of Ceres has exposed
various interesting and exclusive features.
Just like icy moons in the outer solar system have craters with central
pits, but on Ceres central pits in big craters are much more common. These and
other features will let to understand the inner structure of Ceres that we
cannot sense directly.

Niagara Falls
Waterfalls are commonly formed when a river is young. At these times the
channel is often narrow and deep. When the river courses over resistant
bedrock, erosion happens slowly, while downstream the erosion occurs
more rapidly. As the watercourse increases its velocity at the edge of
the waterfall, it plucks material from the riverbed. Whirlpools created
in the turbulence as well as sand and stones carried by the watercourse
increase the erosion capacity. This causes the waterfall to carve deeper
into the bed and to recede upstream. Often over time, the waterfall
will recede back to form a canyon or gorge downstream as it recedes
upstream, and it will carve deeper into the ridge above it. The rate of
retreat for a waterfall can be as high as one and half meters per year.
Often, the rock stratum just below the more resistant shelf will be of a softer type, meaning that undercutting due to splashback will occur here to form a shallow cave-like formation known as a rock shelter under and behind the waterfall. Eventually, the outcropping, more resistant cap rock will collapse under pressure to add blocks of rock to the base of the waterfall. These blocks of rock are then broken down into smaller boulders by attrition as they collide with each other, and they also erode the base of the waterfall by abrasion, creating a deep plunge pool or gorge.

The Augrabies Falls is a waterfall on the Orange River, South Africa
The Augrabies Falls is a waterfall on the Orange River, South Africa,
within the Augrabies Falls National Park. The falls are around 60m in
height. The original Khoikhoi residents named the waterfall "Ankoerebis" "place of big noises" from which the Trek Boers, who settled here
later on, derived the name, "Augrabies". The falls have recorded
7,800 cubic metres of water every second in floods in
1988 (and 6,800 cubic metres (240,000 cu ft) in the floods of 2006.
This is over three times the average high season flow rate of Niagara
Falls of 2,400 cubic meters per second, more than four
times Niagara's annual average, and greater than Niagara's all-time
record of 6,800 cubic meters per second. The gorge at the Augrabies Falls is 240 m deep and 18 km long, and is an impressive example of granite erosion.

The Vivid Green Magpie, A crow family member, vocal sound is peep-peep whistles and chatters.
The most
beautiful green magpie (Scientists name is Cissa Chinensis,) is a member of the
crow family, approximately about the size of the Eurasian jay or a touch
smaller. The magpie is a vivid green in color, marginally lighter on the
underside and has a thick black stripe from the bill to the nape. The bird is compared
to the other members of its genus; the white-tipped tail is fairly long. This
all contrasts vividly with the red fleshy eye rims, bill and legs.
The wings are
reddish maroon. Well, the bird can be found
from the lower Himalayas in north eastern India in a broad south easterly band
down into central Thailand, Malaysia, Sumatra and northwestern Borneo in
evergreen forest including bamboo forest, clearings and scrub. The Magpie bird
naturally searching food both on the ground and in trees, and takes a very high
percentage of animal prey from myriad invertebrates, small reptiles, mammals
and young birds and eggs. It will also take flesh from a carcass. The bird
naturally built nests in trees, large shrubs and every so often in tangles of different
climbing vines. Moreover, the nests usually four to six eggs laid. Moreover,
the bird voice is quite varied but frequently a harsh peep-peep. It also likes
to frequently whistles and chatters. The Green Magpie is classified as
Least Concern, but it does not fall in more at risk category. The Green Magpie
is widespread and abundant taxa are included in this category. Source: Charismatic Planet

Puya berteroniana Blooming Blue
Strange Wonderful Things .Rare and exotic plants &
seeds .From outer space - I mean Chile - comes the amazing, rare
Bromeliad, the Blue Puya. With its massive, 7 foot flower cluster, this
is one of most outrageous plants anywhere. The turquoise-blue color is
very rare in the plant world, and it's even rarer to be combined with
orange.The Blue Puya (P. berteroniana) is a terrestrial Bromeliad
related to Pineapple. The plant forms a rosette of silvery-green leaves
about 3 feet long. The leaves are spiny, so move carefully around the
plant. The flower stalks themselves are soft, and the flowers are
silky-smooth. These other-worldly blooms appear around May or June. It
is an unforgettable experience to stand next to one of these massive,
blue stalks. The blooms are pollinated by birds, which love to sit on
the outward-pointing tips and drink the nectar inside! This species is
rare, and if you can find it, it's sometimes a similar species, Puya
alpestris, mislabeled as Puya berteroniana. Alpestris is a smaller
plant, with shorter, less impressive clusters. This is the genuine Puya
berteroniana.

Reflections on Moraine Lake, Valley of the Ten Peaks
Moraine Lake is a glacially-fed lake in Banff National
Park, 14 kilometres outside the Village of Lake Louise, Alberta,
Canada. It is situated in the Valley of the Ten Peaks, at an elevation
of approximately 1,885 m. The lake has a surface area of .5 square
kilometres (0.19 sq mi). The lake, being glacially fed, does not
reach its crest until mid to late June. When it is full, it reflects a
distinct shade of blue. The colour is due to the refraction of light off
the rock flour deposited in the lake on a continual basis.
