Eagles

 


Eagles are some of the largest birds. They are at the top of the food chain, with some species feeding on big prey like monkeys and sloths. Eagles have amazing eyesight and can detect prey up to two miles away. Eagles are birds of prey in the family: there are approximately 60 different species. The majority are found in Eurasia and Africa, with only 14 species found in other areas including North, Central and South America, and Australia.

How do eagle look like?

 With the exception of some vultures, eagles are generally larger than other birds of prey. They have strong muscular legs, powerful talons and large hooked beaks that enable them to rip the flesh from their prey.


Eagles vary in size. One of the smallest species, the little eagle, is around 17.7–21.7 in (45–55 cm). In contrast, Stellers’s sea eagle is around 36–42 in (91–106 cm) in size, and wingspan can reach approximately 72–96 in (2–2.5 m).

How far do eagle see? 

Sight is the strongest of all eagle senses. The eyes are large, can take up almost 50% of the head, and can weigh the same amount as a human eye. An eagles vision is 4–5 times better than that of a human. Eagle eyes are angled 30 degrees away from centre of the face, which gives eagles a greater field of view. Eagles can see five basic colours to our three, and can detect UV light.Cones are light detecting cells that are sensitive to colour. One of the reasons that eagles have better vision than humans is because their retinas, a layer at the back of the eyeball, have more cones. We have 200,000 cones per square millimetre, whereas eagles have one million.

Do eagles mate? 

Eagles are monogamous, so generally mate for life. They have strong site fidelity, so a mating pair tend to reuse the same nest year after year. Nests, composed of sticks, vegetation, and downy feathers, are built by both males and females. Location of the nest varies with species. Bald eagles for example, most likely nest in tall trees whereas as golden eagles prefer cliff faces or more open areas.

How many eggs do eagles lay?



The number of eggs laid will depend upon species, but many eagles lay between one and three eggs; four egg clutches do occur, but they are rare.

What do eagles eat? 

Eagles are apex predators, meaning they are at the top of the food chain. What eagles eat depends upon the species and the food that is available to them, but they are all carnivorous and live on a diet of meat and/or fish.

BEDBUGS

  B edbugs do not fly, but they can move quickly over floors, walls, and ceilings. Female bedbugs may lay hundreds of eggs, each of which is about the size of a speck of dust, over a lifetime. Adult bedbugs have flat bodies about the size of an apple seed. After feeding, however, their bodies swell and are a reddish color. Immature bedbugs, called nymphs, shed their skins five times before reaching maturity and require a meal of blood before each shedding. Under favorable conditions the bugs can develop fully in as little as a month and produce three or more generations per year. Hidden place of bed bugs Bedbugs may enter your home undetected through luggage, clothing, used beds and chairsr, and other items. Their flattened bodies make it possible for them to fit into tiny spaces. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy

Cat

  T he cat (Felis catus) is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat different from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are cherished by humans for companionship and their ability to kill rodents. The cat is similar in anatomy to the other felid species: it has a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey like mice and rats. Its night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language.  Although the cat is a social species, it is a solitary hunter. As a predator, it is crepuscular, i.e. most active at dawn and dusk. It can hear

SCORPIONS

S corpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Most these scorpion does have venom that can kill among of these scorpion that there venom can kill are not more than 30 species, but I would love explore the six deadliest amongst them. The first scorpion is : Deathstalker Deathstalker is the deadliest scorpion of all if this scorpion has powerful cardiotoxin and nuerotoxin it sting will lead to death if not promptly treated with antivenom even if the victim has no underlying
