Barn Owls Are One Of The Most Widely Distributed Birds

Barn owls are one of the most widely distributed birds found everywhere around the world apart from the polar and desert regions. Although this is the case, the barn owl population is more predominant in the Southern Hemisphere due to better climate conditions for the barn owl.

Barn owls tend to measure between 25 and 40cm tall and adult barn owls can have a wingspan of up to 110cm long. The wing span of the barn owl is however dependent on the species of barn owl so some owls may be smaller, where other species of barn owl may be much bigger.

Surprisingly, these common barn owls do not make the hoot sound that can often be heard at night. Instead the owls produce a high-pitched scream and can also hiss in a similar way to a cat or snake if the barn owl feels threatened.

Barns owls can be most commonly seen in the open countryside and along river banks, fields and even the verges on the side of the road. Barn owls are nocturnal animals meaning that typically barn owls rest during the light day time hours and emerge at dusk to begin a night of hunting.

Barn owls most commonly hunt small mammals such as mice, voles and rats but barn owls also hunt fish close to the surface of the water and smaller birds in the tree tops and even in the air. Barn owls swallow their prey whole and then bring back up (regurgitate) the indigestible parts such as bones in the form of a small pellet.

Barn owls are well suited to their nocturnal lifestyle. The large eyes of the barn owl enable the barn owl to have fantastic eyesight even in the darkness of night, but barn owls also have incredibly accurate hearing. The ears of the barn owl are set with one higher than the other giving the barn owl better hearing in general but it also means that when the barn owl is hunting for prey, it can use one ear to detect noise on the ground below and the other ear is used to detect noise from the air and trees above.

Female barn owls lay a clutch of up to 7 eggs in the warm months of spring. The female barn owl nests in a hollow tree or rock, and the barn owl eggs usually hatch after about a month. The male barn owl is known to help feed the barn owl chicks and the barn owl chicks are able to fly by the time they are 12 weeks old.

Although the barn owl, is not considered to be a threatened species of animal, the barn owl population numbers have severely decreased over the years due to pollution and habitat loss as the barn owls are finding it harder and harder in some areas to find food. Despite this being true, the barn owl population in the UK is thought to be increasing again.

There are more than 30 different species of barn owl found across Europe, Africa, Asia and parts of Australia and the Americas. All barn owl species have a similar appearance but can differ great in both size and colour.

African Penguin Conservation Status And Life Today

The African Penguin is a small to medium sized Penguin species that is found along the coast of South Africa and on a number of it's surrounding islands. The African Penguin is thought to be most closely related to the Humboldt and Magellanic Penguins found in southern South America, and the Galapagos Penguin found in the Pacific Ocean near the Equator. The African Penguin was named for the fact that it is the only species of Penguin that is found breeding on the African Coast, and it is believed to be one of the first Penguin species to be discovered by humans.

The African Penguin is a fairly distinctive species of penguin with clean black and white markings and a sharply pointed black beak. The African Penguin also has black feet and a number of dot-like markings flecked across it's white chest which are said to be as unique to the individual Penguin as a Human finger print is, along with a narrow black band. The male African Penguin is generally slightly larger than their female counterparts but both are fairly similar in appearance.

One of the African Penguin's most distinctive features is that they have pink glands above their eyes which help them to cope with the temperate climates. The hotter the African Penguin gets, the more blood is sent to these glands so it may be cooled by the surrounding air, which in turn, makes these glands more pink.
The African Penguin is found on the south-western coast of Africa, living in 27 colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa, with the largest colony found on Dyer Island, near Kleinbaai. African Penguins are most densely distributed around the cold, nutrient rich waters of the Benguela Current where there is a plentiful supply of food. Although they spend much of their time at sea, African Penguins gather in nesting sites on rocky islands where they spend their days in sheltered burrows to avoid the hot sun. They are one of the only Penguin species to be found in non-freezing conditions and cope with this by burrowing, emerging at dusk and dawn, and using the pink glands above their eyes to cool the blood down.

Like many other Penguin species, African Penguins are incredibly sociable birds, with adults forming pair bonds that last for life (as long as 10 years). African Penguins can often be seen grooming one another, which is not only practical for cleaning purposes, but also for removing parasites and even just rearranging feathers, constantly strengthening the social bond between the pair. Their courtship displays are often very noisy as the male and female Penguin call to each other using a series of donkey-like sounds. African Penguins are also known to submit to a spot of bathing only a few meters from the shore, which they are thought to do quite regularly to both clean and to cool themselves down in the heat.

African Penguins begin to breed at the average age of four, when a male and female will pair up, and tend to breed together for the rest of their lives. The female African Penguin either digs herself a burrow or finds a dip beneath a rock or bush, in which she lays two eggs. The eggs are incubated by both parents for up to 40 days, when only one of the eggs will usually hatch. The African Penguin chicks are fed and kept warm by their parents constantly until they are a month old when they begin to be left on their own, forming crèches with other chicks for protection from predators. They tend to remain with their parents until they are between 3 and 5 months old, when they will leave the colony (this is dependant though on the supply and quality of food in the area). The chicks return to the colony after a couple of years to moult into their adult plumage. African Penguins generally live for between 10 and 15 years.

The African Penguin is a carnivorous animal that, like all other Penguin species, survives on a diet that is only comprised of marine organisms. Shoaling fish including Anchovies, Sardines, Horse Mackerel and Round Herrings make up the bulk of the African Penguin's diet, along with the occasional Squid or Crustacean when normal food is in short supply. The streamlined body of the African Penguin allows it to move through the water like a rocket, capable of reaching a top speed of around 20 kph when hunting for food. African Penguins catch their prey by diving into the ocean depths for around 2 minutes at a time. Although they normally go to depths of around 30 meters, it is not uncommon for them to be found hunting more than 100 meters beneath the water's surface.

The African Penguin's smaller size means that it has many predators both in the water and also on dry land. Their marine predators are primarily Sharks and Cape Fur Seals, but the biggest threat to them on land is not just to the adult Penguins, but more the vulnerable eggs and chicks. Kelp Gulls and Scared Ibises prey on them from the air and Mongooses, Snakes, and Leopards have been observed hunting them on ground. The African Penguin has also been severely affected by Human activity in their native regions, with populations thought to have taken a drastic decline, mainly due to the exploitation of their eggs for food when they were first discovered. They are also severely affected by the disruption of their natural habitats.

Penguins have more feathers than any other bird, which act as a waterproof layer keeping their skin dry. African Penguins moult once a year which they do back in their colonies. The whole process lasts for about 20 days, in which time, the African Penguins cannot swim or eat, and can lose almost half of their body weight. African Penguins are known to spend long periods of time fishing out at sea, and depending on the area, can travel between 30 and 110 km in one trip. However, those African Penguins who have chicks to feed, will rarely go that far, catching food closer to the shore, and as quickly as possible. The African Penguin is also known as the Jackass penguin, due to the donkey-like call that they make during their courtship rituals.

It is widely believed that African Penguins were one of the first Penguin species to come into contact with Humans, due to the fact that they are found on the temperate South African coast rather than in the heart of Antarctica. This however, does not seem to have worked to the bird's advantage as their eggs were stolen for food (slowing the rate of reproduction), and the guano used in nest building was harvested for fertiliser. Today, other threats face the African Penguin including competition for food from commercial fishing and oil pollution in the water. Only a small handful of nesting sites can be accessed by tourists, but the Penguin's nervous nature of people means that these areas have to be strictly monitored.

Today, the African Penguin is considered to be a vulnerable animal and has been listed as being Endangered by the IUCN. It is thought that today's African Penguin population of around 70,000 breeding pairs, is less than 10% of the population that existed in 1900. By the 1950s, the African Penguin population had halved, and it had then halved again by 1980. There is an approximate 2% decline in the African Penguin population every year, mainly due to the Human consumption of their eggs, competition for food and habitat disruption.

Afghan Hound Physical Characteristics And Interesting Facts

Afghan Hound is thought to be one of the oldest of all domestic Dog breeds, with the first records of the Afghan Hound dating back to 4,000 BC. The fast and agile nature of this Dog meant that they made excellent hunters of small game in their native Afghanistan, most commonly hunting Deer, Goats, Gazelle and Wild Boar along with seeing off larger predators such as Wolves and Snow Leopards. Their gentle nature also made this elegant sight-hound a doting shepherd, fearlessly protecting livestock from hungry predators. This beautiful but gently natured watchdog was brought to Britain in the early 1920s and it's entry to the USA followed in 1926. The elegance of the Afghan Hound meant that they quickly became highly desirable Dogs, both as pets and for show.

Afghan Hound Physical Characteristics

The most characteristic feature of this breed is the long, silky fur that covers the Afghan Hound's body, most notably on the top of it's head. Afghan Hounds are most commonly black or golden in colour although a number of colour variations now exist within the breed including brown, grey and white. The elongated head and muzzle of the Afghan Hound make them easily identifiable, along with their high hip-bones which gave the ancestors of the modern day Afghan Hound their reputation for speed and agility. The face of the Afghan Hound is usually a black-coloured mask, with a black nose and dark almond shaped eyes. The colour of the facial mask is known to vary although white is said to be discouraged as it is seen as a sign of poor breeding. They are fairly large Dogs standing on average at 68cm in height.

Afghan Hound Behaviour and Temperament

The temperament of the typical Afghan Hound tends to be aloof and dignified, but happy and intelligent and generally relatively playful. However, the Afghan Hound has a reputation among Dog trainers for having a relatively slow obedience intelligence possibly due to their slightly stubborn nature. The Afghan Hound has a leaning towards independence and owners should not be surprised if their Dog sometimes chooses to ignore commands. The modern day Afghan Hound is said to have many Cat-like tendencies, loving to laze around the house and is generally much slower than it's Middle Eastern ancestors. The Afghan Hound is seldom used for hunting in Europe and America today where they are one of the most popular domestic Dog breeds.

Afghan Hound Breeding

The Afghan Hound was first bred in the ancient deserts of Egypt and Afghanistan, where they were primarily used as hunters. The Afghan Hound was a favoured choice of Dog as they were able to outrun the majority of other animals, whilst being courageous hunters and were capable of thinking independently, often able to keep larger prey from escaping until the hunter arrived. The first domestic breeding of the modern day Afghan Hound was by an English officer station near Kabul, who later brought the Afghan Hound to the UK in 1925. A year later, the Afghan Hound was taken to America where it's beauty and elegance made it one of the most prestigious breeds of domestic Dog in the States.The average litter size of the Afghan Hound is around 7 puppies, which are blind when first born.

Afghan Hound Interesting Facts and Features

When the Afghan Hound breed was first brought to America, it's naturally independent nature led to it gaining a reputation for being untrustworthy. Today however, many of these traits are not quite as prominent in the breed as they once were. The high hip-bones of this Dog are thought to be one of the main reasons why the Afghan Hound once had a reputation for speed, making them faster at running than most other domestic Dog breeds today. The long topknot on the top of it's head, along with the small ring near the end of it's tail, are two of the most distinctive features of the mature Afghan Hound. They originate from the mountains of Afghanistan and their unique appearance provides these Dogs with vital advantages during the cold winters and hot summers. Although beautiful, this long fur takes daily care and maintenance to ensure that the coat remains healthy.

Lovely Goose Even Lives In The Wild

A lovely goose is a medium to large sized bird found in Europe, Asia and North America. There are around 29 known species of geese around the world including Canadian geese and Snowy geese.

Geese mate and build their nests in order to raise their baby geese (known as goslings) in the north during the warmer summer months and the geese then migrate south in the winter to the warmer climates when the baby geese are strong enough to fly.

Geese tend to have the same mating partners for their entire lives, and if not all of it then most of it. The bond between male and female geese partners is very strong and they will often spend most of their time together with both the male goose and the female goose building the nest and raising their young.

Geese are omnivorous birds but mainly feed on insects, grubs, small fish and plankton in the water. Geese spend a great deal of time on the water and have special adaptations such as webbed feet which make their aquatic life easier.
Geese have a number of natural predators although, due to the size and strength of a goose, predatory animals don't always have an easy time if they fancy goose for dinner. The main predators of the goose are foxes, wild dogs, raccoons and birds that predominately prey on the goose eggs and newborn baby geese. Humans are among one of the most common predators of geese, as geese are hunted all around the world for their meat and feathers.

Geese are strong and hardy birds and are known to get to old ages, even in the wild. The average lifespan of a goose is between 20 and 30 years but a number of geese individuals have been known to live for much longer.

Geese are known to have extremely strong wings as they migrate long distances every year to the warmer climates. Due to the fact that the wingspan of a goose is so large (normally one and half times the size of the goose's body), and the wings of the goose are so strong, a goose is known to be able to inflict severe damage to humans should it become threatened or annoyed!

Not only do geese flap their wings to intimidate unwanted company, but they are also known to make a loud hissing noise. If these methods of defence fail, it is not uncommon for a goose to simply charge at the intruder hissing and flapping it's wings all at the same time.

The term geese is normally used to refer to these birds in general, but more particularly a female. The term gander is generally used to refer to a male.. The baby geese are referred to as goslings and a group of geese on the ground is called a gaggle with geese flying in formation being called a wedge or a skein.

The Beautiful Peacocks That We All Love

The peacock (also known as peafowl) is a medium sized bird most closely related to the pheasant. Unlike it's common pheasant cousin that inhabits areas of the Northern Hemisphere, the peacock is found in warmer climate of the Southern Hemisphere, with the peacock being most commonly found in India.

There are three main types of peacock, the African Congo peacock, the Indian peacock and the Green peacock all of which are thought to have originated in Asia but are today found in Africa and parts of Australia. All of the three different species of peacock are knwon for their elaborate male peacocks and dull, brown female peacocks (in comparison to the males).

The male peacock is most well known for it's enormous tail feathers that fan out behind the peacock and can be nearly two meters in length. This colourful display of the peacock is thought to be used for both mating and defence purposes. The male peacock attracts a female to mate with by showing off his array of elaborate feathers, and when the male peacock feels threatened, he will fan his tail out in order to make himself look bigger and therefore try to intimidate approaching predators.

The peacock is an omnivorous bird and feeds on insects, plants, seeds, and flower heads. Peacocks have also been known to munch on small mammals and reptiles in order to supplement their diet, which ensures that they are getting the right nutrients. Peacocks have a number of natural predators in the wild that include wild dogs and cats, medium sized mammals such as raccoons and even tigers have been known to hunt peacocks.

Peacocks commonly get to about 20 years old, although some peacock individuals have been known to get to older ages particularly those peacock individuals that are in captivity. Generally, the peacock populations are not under great threat although the green peacock, is listed as being vulnerable to extinction mainly due to hunting and habitat loss.

Male peacocks are known as peacocks and female peacocks are known as peahens (in a similar way to chickens and pheasants). The male is peacock is generally about twice the size of the female peahen, and even larger when the male peacock is displaying his plumage (feathers). When the male peacock does not have his brightly coloured and very elaborate tail feathers on display, they drag behind him. This is known as a tail or a train.

During the mating season, the male peacock may mate with up to six different female peahens. The female peahen lays between 4 and 8 brown coloured eggs. The female peahen incubates her eggs by sitting on them, and the peacock chicks hatch after an incubation period of about a month. The female peacock, looks after and rears her peacock chicks on her own without any help from the male peacock.

Peacocks are most commonly found in deserts and dry savanna areas. Peacocks are also found in forests and dense foliage particularly during the breeding season when the female peacocks are trying to incubate their eggs and rear their chicks without any unwelcome predators spotting them.
