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.

Sunrise Time Lapse Video
Although the Sun appears to "rise" from the horizon, it is actually the Earth's motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion is so convincing that many cultures had mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century.[3]
Architect Buckminster Fuller proposed the terms "sunsight" and "sunclipse" to better represent the heliocentric model, though the terms have not entered into common language.
Beginning and End
Astronomically, sunrise occurs for only an instant: the moment at which the upper limb of the Sun appears tangent to the horizon.[1] However, the term sunrise commonly refers to periods of time both before and after this point:
Twilight, the period in the morning during which the sky is brightening, but the Sun is not yet visible. The beginning of morning twilight is called astronomical dawn.
The period after the Sun rises during which striking colors and atmospheric effects are still seen.[2]
Angle Edit
The stage of sunrise known as false sunrise actually occurs before the Sun truly reaches the horizon because Earth's atmosphere refracts the Sun's image. At the horizon, the average amount of refraction is 34 arcminutes, though this amount varies based on atmospheric conditions.[1]
Also, unlike most other solar measurements, sunrise occurs when the Sun's upper limb, rather than its center, appears to cross the horizon. The apparent radius of the Sun at the horizon is 16 arcminutes.[1]
These two angles combine to define sunrise to occur when the Sun's center is 50 arcminutes below the horizon, or 90.83° from the zenith.[1]
Time of Day Edit
The timing of sunrise varies throughout the year and is also affected by the viewer's latitude and longitude, altitude, and time zone. These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet's movement in its annual elliptical orbit around the Sun, and the Earth and Moon's paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise.
In late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth's orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.
Variations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly.[1]
Accounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun's physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.
Neglecting the effects of refraction and the Sun's non-zero size, whenever sunrise occurs, in temperate regions it is always in the northeast quadrant from the March equinox to the September equinox and in the southeast quadrant from the September equinox to the March equinox.[4] Sunrises occur approximately due east on the March and September equinoxes for all viewers on Earth.[5] Exact calculations of the azimuths of sunrise on other dates are complex, but they can be estimated with reasonable accuracy by using the analemma.
The figure on the right is calculated using the solar geometry routine in Ref. [6] as follows: 1.) For a given latitude and a given date, calculate the declination of the Sun using {\displaystyle 0^{\circ }}{\displaystyle 0^{\circ }} longitude and solar noon time as inputs to the routine; 2.) Calculate the sunrise hour angle using the sunrise equation; 3.) Calculate the sunrise time, which is the solar noon time minus the sunrise hour angle in degree divided by 15; 4.) Use the sunrise time as input to the solar geometry routine to get the solar azimuth angle at sunrise.
Hemispheric symmetry Edit
An interesting feature in the figure on the right is apparent hemispheric symmetry in regions where daily sunrise and sunset actually occur.
This symmetry becomes clear if the hemispheric relation in sunrise equation is applied to the x- and y-components of the solar vector presented.

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.

Do Pigeons Like Music Yes or No?
Pigeons live near humans. Many are kept as pets. Others live in the cities around humans all day. As a result, they are often exposed to loud music and noises. Nevertheless, do pigeons like what they hear?
Pigeons don’t like everything they hear. They like to listen to tunes but dislike unnecessary loud noises. It may sound funny, but they have their tastes just like we do.
Many pigeon owners have said that their pets enjoy listening to classical and instrumental music most. Some even claim that their pet pigeons love to hear them singing. It is not an uncommon phenomenon.
Many birds are attracted to soothing recitation or music. This is pretty common among the birds. This is why stories like birds attracted to a singing princess were pretty common in the old days. This indicated how well the princess could sing.

Hunting Methods of the Insect-Eating Gualin
A small white heron or sometimes called gaulin which spends most of its time around cattle and livestock instead of water wading as most herons do. They feed on the insects and grubs disturbed by the grazing animals. Green Backed Herons
It is known locally as a gaulin and is thought to be one of the most intelligent of animals – it's been seen using bait to catch fish! Hummingbirds, the Gray Kingbird and the ubiquitous black bird are also regularly seen around the gully. You would see many of these birds where there are tractors and backhoes, they wait patiently when the soil is dug up to eat the small insects that surfaces out of the dirt.
