From Sunset Till First Light London Timelapse
A beautiful view from dusk till dawn in London from the setting of sun to the first light that brings forth the new day. We as a whole realize that dawn or day break is the point at which the sun comes up and nightfall or sunset is the point at which it goes down yet imagine a scenario where we need a more exact opportunity to allude to.
The distributed occasions of dawn and dusk allude to the second when the Sun's upper appendage, as influenced by refraction, is on the genuine skyline of an onlooker adrift level. This happens when the Sun's middle is 50 arcminutes beneath the genuine skyline, the upper appendage then, at that point being 34 arcminutes (only more than the Sun's clear width) underneath the genuine skyline.

The Stunning Aurora Borealis Northern Lights
An aurora is a natural light display that shimmers in the sky. Colourful blue, red, yellow, green, and orange lights shift gently and change shape like softly blowing curtains. Auroras are only visible at night, and usually only appear in lower polar regions.
Auroras are visible almost every night near the Arctic and Antarctic Circles, which are about 66.5 degrees north and south of the Equator. In the north, the display is called aurora borealis, or northern lights. In the south, it is called aurora australis, or southern lights.
Auroras and the Solar Wind
The activity that creates auroras begins with the sun. The sun is a ball of superhot gases made up of electrically charged particles called ions. The ions, which continuously stream from the sun’s surface, are called the solar wind.
As the solar wind approaches the Earth, it meets the Earth’s magnetic field. Without this magnetic field protecting the planet, the solar wind would blow away Earth’s fragile atmosphere, preventing all life. Most of the solar wind is blocked by the magnetosphere, and the ions, forced around the planet, continue to travel farther into the solar system.
Although most of the solar wind is blocked by the magnetosphere, some of the ions become briefly trapped in ring-shaped holding areas around the planet. These areas, in a region of the atmosphere, called the ionosphere, are centered around the Earth’s geomagnetic poles. The geomagnetic poles mark the tilted axis of the Earth’s magnetic field. They lie about 1,300 kilometres (800 miles) from the geographic poles but are slowly moving.
In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth’s atmosphere. The energy released during these collisions causes a colourful glowing halo around the poles—an aurora. Most auroras happen about 97-1,000 kilometres (60-620 miles) above the Earth’s surface.
The most active auroras happen when the solar wind is the strongest. The solar wind is usually fairly constant, but solar weather—the heating and cooling of different parts of the sun—can change daily.
Solar weather is often measured in sunspots. Sunspots are the coldest part of the sun and appear as dark blobs on its white-hot surface. Solar flares and coronal mass ejections are associated with sunspots. Solar flares and coronal mass ejections are sudden, extra bursts of energy in the solar wind. Sunspot activity is tracked over an 11-year cycle. Bright, consistent auroras are most visible during the height of sunspot activity.
Some increased activity in the solar wind happens during every equinox. These regular fluctuations are known as magnetic storms. Magnetic storms can lead to auroras being seen in the midlatitudes during the time around the spring and autumnal equinoxes. Auroras have been visible as far south as the Yucatan Peninsula in Mexico.
Magnetic storms and active auroras can sometimes interfere with communications. They can disrupt radio and radar signals. Intense magnetic storms can even disable communication satellites.
Colouring an Aurora
The colours of the aurora vary, depending on altitude and the kind of atoms involved. If ions strike oxygen atoms high in the atmosphere, the interaction produces a red glow. This is an unusual aurora—the most familiar display, a green-yellow hue, occurs as ions strike oxygen at lower altitudes. Reddish and bluish light that often appears in the lower fringes of auroras is produced by ions striking atoms of nitrogen. Ions striking hydrogen and helium atoms can produce blue and purple auroras, although our eyes can rarely detect this part of the electromagnetic spectrum.

A Delightful Feline Becomes a Close Acquaintance with a Baby Monkey
A cat comes to be a close friend of a Baby Monkey. The little cat licks the baby monkey's face comforting it while it sleeps. They look so cute together, the cat gives a big yawn at the end before relaxing next to his best friend.
Kittens are social from a very early age. They rely on interaction with the queen for survival and to learn important life skills such as grooming, hunting, feeding, and agonistic and affiliative behaviours (Figure 4-7). They also rely on interaction with littermates to learn social skills such as threat behaviours and affiliative behaviours. Kittens begin to show social behaviors as their eyes and ears open and their nerves and muscles develop enough that they can change the position of the ears, tail, body, and hair. This begins to occur from 7 days of age onward.
During the first 2 months of their lives, kittens form social relationships. These include relationships with other cats, with people, and with other animals (Figure 4-8, A–C). The kittens prefer their mother over other adult cats but will accept care from familiar adult female cats. This is seen when related queens cross foster their kittens.28 The developmental stages of the kitten and socialization with people have not been studied as thoroughly as in dogs.29 It has been suggested that kittens pass through their major developmental stages at earlier ages than dogs do,30 although more recent research into dog development has suggested that the important phase in terms of dogs’ social development may be earlier than first thought. Certainly, kittens need socialization opportunities at a very young age if they are to accept other cats, people, and other animals as part of their milieu, and research has suggested the period from 2 to 7 weeks of age is of particular importance. When kittens were raised with rats of different strains, in general they did not prey on the strain of rat with which they were raised but would attack rats of different strains,31 which illustrates how important early exposure is to the kittens’ perception of other species later in life.
There are lifelong consequences for a kitten whose social environment is impoverished. Kittens isolated starting from a young age were found to develop behavioral, emotional, and physical problems. They were fearful and aggressive, had difficulty learning, and exhibited random, undirected locomotor activity.32 They also did not play when exposed to other kittens.33 This has important implications for hand-rearing single kittens. Whereas a queen with a single kitten socializes her kitten by playing with it,34 a solo hand-reared kitten does not experience this important interaction. Where possible, single orphan kittens should be fostered onto a queen or raised with other kittens or cats that are friendly towards kittens. If these options are not available, some have suggested that euthanizing the kitten may be better than raising an animal likely to develop behavior problems.
Young kittens also practice hunting behavior in a social setting. The presence of the mother and littermates increases their interest in prey animals.35,36 Kittens learn how to deal with different species of prey from watching their mother dispatch and dismantle them. This social learning continues into adult life as they learn how to deal with novel prey species by watching other cats kill them.31 Kittens also learn a novel operant-conditioning activity faster when they watch their mother learn it and perform it.37
Play is used to practice behaviors needed for adult life. The play behaviors kittens show changes with their age and development. Social play is seen before approximately 8 weeks of age, but it gradually is replaced with play directed at inanimate objects after 8 weeks.38
After weaning, when play is directed towards littermates, it includes predatory and agonistic behaviors30 (Figure 4-9). Play bouts may end in a fight, with the fighting part of the bout becoming more prevalent.30 As kittens reach the age of dispersal, social play and interactions begin to decline.

Daring birds shield their home from reptile
Two brave birds safeguard their house from a monitor lizard who is after their eggs. The female dikkop bird spots the lizard approaching and quickly attacks him.
Defending its territory with a courageous move, it pulls on the lizard's tail. Suddenly, the male dikkop abandoning its nest comes to assist the female with a two-against-one strategy.
The monitor lizard knows that it can't win the battle and retreats to the area where it is not threatened. There it waits, hoping for them to drop their guard so he can claim his prize.

Mother goat teaches her kid a lesson in cliff climbing
She goes ahead first and the kid follows sharply behind her. The cliff is vertical and very dangerous, they both slip and slide, but by maintaining their balance the task was accomplished. It's remarkable the courage and stamina that they have to climb up such a dangerous mountain.
A goat is any ruminant and hollow-horned mammal belonging to the genus Capra. Related to the sheep, the goat is lighter in build, has horns that arch backwards, a short tail, and straighter hair. Male goats, called bucks or billys, usually have a beard. Females are called does or nannies, and immature goats are called kids. Wild goats include the ibex and markhor.
Domesticated goats are descended from the pasang (Capra aegagrus), which is probably native to Asia, the earliest records being Persian. In China, Great Britain, Europe, and North America, the domestic goat is primarily a milk producer, with a large portion of the milk being used to make cheese. One or two goats will supply sufficient milk for a family throughout the year and can be maintained in small quarters, where it would be uneconomical to keep a cow. For large-scale milk production, goats are inferior to cattle in the temperate zone but superior in the torrid and frigid zones. Goat flesh is edible, from young kids being quite tender and more delicate in flavour than lamb, which it resembles. Some breeds, notably the Angora and Cashmere, are raised for their wool (see also wool; cashmere; Angora goat); young goats are the source of kid leather.

The Effortless cascade streams mysteriously spouting over the stones
The waterfall is stunningly beautiful like aquatic blue as it flows gracefully downstream. A waterfall is a river or other body of water's steep fall over a rocky ledge into a plunge pool below. Waterfalls are also called cascades.
The process of erosion, the wearing away of earth, plays an important part in the formation of waterfalls. Waterfalls themselves also contribute to erosion.
Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.
A fall line is the imaginary line along which parallel rivers plunge as they flow from uplands to lowlands. Many waterfalls in an area help geologists and hydrologists determine a region's fall line and underlying rock structure.
As a stream flows, it carries sediment. The sediment can be microscopic silt, pebbles, or even boulders. Sediment can erode stream beds made of soft rock, such as sandstone or limestone. Eventually, the stream's channel cuts so deep into the stream bed that only a harder rock, such as granite, remains. Waterfalls develop as these granite formations form cliffs and ledges.
A stream's velocity increases as it nears a waterfall, increasing the amount of erosion taking place. The movement of water at the top of a waterfall can erode rocks to be very flat and smooth. Rushing water and sediment topple over the waterfall, eroding the plunge pool at the base. The crashing flow of the water may also create powerful whirlpools that erode the rock of the plunge pool beneath them.
The resulting erosion at the base of a waterfall can be very dramatic, and cause the waterfall to "recede." The area behind the waterfall is worn away, creating a hollow, cave-like structure called a "rock shelter." Eventually, the rocky ledge (called the outcropping) may tumble down, sending boulders into the stream bed and plunge pool below. This causes the waterfall to "recede" many meters upstream. The waterfall erosion process starts again, breaking down the boulders of the former outcropping.
Erosion is just one process that can form waterfalls. A waterfall may form across a fault, or crack in the Earth’s surface. An earthquake, landslide, glacier, or volcano may also disrupt stream beds and help create waterfalls.

Hermit crab finds luxurious homes and can't decide
How to decide which home is more suitable for it to live in. The first home needed cleaning up but was very comfortable. Then it spotted another home and was excited to try it out also.
Anatomy
Hermit crabs are invertebrates, but they do have an exoskeleton, or outer shell, that provides support for their body. They have ten joint legs, and usually, the front two are of different sizes. The large left claw is used for defence, and the smaller right claw for scooping food and water. Two pairs of sensory antennae and two compound eyes at the end of stalks provide information about their surroundings. They breathe through modified gills.
Shells
Because the hermit crab doesn’t have a very hard shell, and its abdomen is soft and vulnerable, it uses other animals' old shells for protection. Snail shells are common protection for hermit crabs. When it finds a proper shell, it pulls itself inside, leaving its head and several claws outside for locomotion, defence and feeding. The flexible body allows it to twist inside a variety of shells. When it outgrows its shell, seeks a larger one.
Moulting
Hermit crabs grow by shedding their exoskeletons and growing a new one, a process called moulting. This happens about once a year, but smaller crabs might moult more often. You probably will see signs that your crab is ready to moult. His eyes will get cloudy, he will eat and drink more, and he will dig in the sand. Moulting is stressful for your crab, and he feels safer hiding in the sand. Provide him with extra water, as well as foods high in calcium. Give him a couple of larger shells to choose from for his new home. Leave his old shell, though, as he might eat it for the nutrients.
Behaviour
Hermit crabs are fun to watch as they go about the business of being crabs. These nocturnal creatures generally are quiet during the day, but come alive after sunset. Two are better than one – despite his name, this is a social creature. Tank mates will engage in play, climb over each other and try on other shells. Place similar-sized crabs together to avoid dominant behaviour.

A Bullfrog Father Protects His Tadpoles
The little pool of water he spawns his young ones into, the water is beginning to dry up. The mother bullfrog leaves him behind to watch over the newly hatched tadpoles, he must show that he is a devoted father and dig a new channel to a larger water source to save his offspring. He must move quickly for each minute the sun rays are drying up the little pool and the tadpoles are clustered up together in the little water that remains. Finally, he succeeded in digging a channel to a larger water pool and he stands guard as the young tadpoles rush down the channel into the large pool of water and are saved.
The baritone call of the bullfrog is so deep and resonant, it resembles the mooing of a cow, hence its name. Only males emit this trademark "jug-o-rum" bellow, and their choruses can be heard during the day or night.
Size
The largest of all North American frogs, this giant can grow to a length of 8 inches or more and weigh up to 1.5 pounds. Even the tadpoles of this species can reach 6.75 inches in length.
Population Range
They are among the most wide-ranging of all North American amphibians, found in freshwater ponds, lakes, and marshes from Nova Scotia, Canada, throughout the continental United States, and as far south as Mexico and Cuba. They have even found their way to Europe, South America, and Asia.
Behaviour
Bullfrogs are typically green or grey-brown with brown spots and have easily identifiable circular eardrums, or tympanum, on either side of their heads.

Nocturnal predators, they will ambush and eat just about anything they can fit in their ample mouths, including insects, mice, fish, birds, and snakes. They sit quietly and wait for prey to pass by, then lunge with their powerful hind legs, mouths open wide.
Males are highly territorial and will aggressively guard their land.

testosterone-fueled aggression and territoriality between roosters
BIRDS ARE NATURAL FIGHTERS
While birds will fight over food, territory or mates, such fights are generally only to establish dominance within a group (the pecking order) and seldom result in serious injury. This natural behaviour is quite different from what happens in staged cockfights, where the animal’s will to survive is exploited. Winning gamebirds are a result of artificial selection—intentionally bred for maximum aggression.
COCKFIGHTS ARE PART OF OUR CULTURE/HERITAGE
While it is true that cockfighting has been practised for centuries in various countries, including the United States, "old" does not necessarily mean right or even acceptable. Heritage cannot be a defence for inexcusable, intentional abuse for the sake of entertainment. Cockfights are centred on animal suffering and apologists try to dress it up as tradition to disguise and excuse the egregious cruelty they inflict. By passing strong laws against animal fighting, federal and state governments have declared that it no longer has a place in our society.

A bullfrog establishes total supremacy over its rival
With the increase in popularity of mixed martial arts grappling has become an increasingly popular sport . But did you know many animals also grapple? Many times they do so to attract the attention of females or to procure rights to a mating territory or mate. Bullfrogs are great grapplers and they fight for their territory.

Apple tree blooming beautiful petals of pink
Tight clusters of furry silver adorn the apple tree blooms at this stage of growth. The leaves have unfurled at this point, revealing tight silver clusters that will eventually spread outward and develop into pink buds. You will be able to see tiny green flower buds on the blooms at this stage.
Apple blossoms are small to medium-sized flowers, averaging 3 to 5 centimeters in diameter, and are comprised of five ovate petals. The petals are arranged in a single layer, surrounding long, wispy yellow stamens. Apple blossoms grow in clusters of 4 to 6 buds attached to spindly branches with small lanceolate leaves.

Strange Jellyfish Glowing in the Ocean Deep
These types of jellyfish can be found in the darkest part of the ocean where the sun cannot penetrate. The first time you see one of these jellyfish glow, its pretty amazing. Bioluminescence is light produced by a chemical process within a living organism. The glow occurs when a substance called luciferin reacts with oxygen. This releases energy, and light is emitted. This is a strange phenomenon that occurs in squids, octopuses, fishes, shrimps, single-celled organisms.

Shoaling and schooling behavior of fish
A school is a group of the same fish species swimming together in synchrony; turning, twisting and forming sweeping, glinting shapes in the water. Fish does this to confuse predators and to save energy. Schooling fish are usually of the same species and the same age and size and silvery, so its difficult for a visually oriented predator to pick an individual out of a mass of twisting, flashing fish and then have enough time to grab its prey before it disappears into the shoal. Fish schools move with the individual members precisely spaced from each other. The schools undertake complicated maneuvers, as though the schools have minds of their own.

Pelican Dives into the Water To Catch Fish
A Seabird plunges in and spoons up a fish from out of the water and snags it in mid-air in its jaws, before swallowing it completely. They may form a line or a "U" shape and drive fish into shallow water by beating their wings on the surface. When fish congregate in the shallows, these birds simply scoop them up. The fish becomes easy pickings for all sorts of birds like the pelicans for example.

How Does Hermit Crab Changes it's Shell in the Ocean?
Today, we at Ocean Conservancy dive into the ever-changing world of hermit crabs. They are well-known for their ability to change shells, as they grow or as they find one that suits them better. There are two types of hermit crabs: land and aquatic. Land hermit crabs spend most of their lives on land and rarely submerge in the water. Aquatic hermit crabs spend most of their lives in the water and rarely leave for land.
Hermit crabs are crustaceans—a group of animals that have a hard shell (exoskeleton), ten jointed legs and a symmetrical segmented body. They have two compound eyes and two pairs of antennae (one pair for feeling and sensing vibrations and one pair for tasting and smelling). There are more than 1,000 species of hermit crabs, and most are native to tropical climates like the Caribbean, South America, Africa and Australia. Some hermit crabs can also be found living along the Atlantic coast of the United States. Hermit crabs are omnivores, animals that eat plants and meat. They forage for worms, plankton, algae, dead fish and whatever else they can find in the sand. Like most scavengers, hermit crabs play an important role by cleaning up their natural ecosystems.
Huzzah! They’re Not Really Hermits at All
When you think of the word “hermit,” you most likely picture someone who enjoys a solitary life without interactions with others, but the life or a hermit crab couldn’t be further from that description! Contrary to their name, hermit crabs live very social lives. They live in big groups, travel together and even meet up to search for food and shells. Perhaps, these animals should be renamed Huzzah Crabs!
When it’s time to upgrade shells, they work together as a team. The hermit crabs gather in a line from the biggest to the smallest crab. Then, the hermit crabs use a cascading effect to quickly transition out of their shells, give their shells to their smaller neighbors and accept a bigger shell from a larger neighbor, passing shells along until everyone is safe and secure in a new home. It’s fascinating.
But, not everything is sunshine and rainbows. Sometimes hermit crabs are known to violently steal a shell from another hermit crab.
A Shell Game
Hermit crabs are very resourceful. They have exoskeletons like other crustaceans but rely on other animals’ shells for additional support. A hermit crab without a shell is a rare sighting; they have a soft, spiraled abdomen that fits perfectly into shells. Every time the hermit crab molts (or sheds its exoskeleton to grow), it must find a new, bigger shell.
