Every year, we get to see millions of birds literally fly half way across the world to other destinations, only to come back to their original home a few months later. And though we may not know it, not all the birds that make this perilous journey over unknown territories survive. But that doesn’t stop them in any way; which makes us think, ‘Why do birds migrate anyway?’ Here are some possible reasons why!
We love them and pet them but when we try to take pictures, their eyes become tiny torch-lights and our well known pets look very fierce and alien to us. Dogs, just like cats and horses, have the ability to see in the dark and when a light is flashed on their eyes in the dark it starts to glow bright. The gleam in the eyes of the dogs is a natural phenomenon. They are natural hunters and hunt at night. It might seem eerie or even scary to you but the burning eyes of your dogs are just normal. Science explains the glowing dog-eyes perfectly.
National Football League players need to be focused, disciplined and very serious about their game. They cannot let anything come between them and their goal. Adverse weather and a diverted mind can change the way a player tackles the football. NFL players believe in taking extra precaution and are prepared for difficult circumstances. They have to play in very tough circumstances and sometimes even in freezing cold weather. The fanny packs are worn by the NFL players so that they can keep their hands warm even if the weather turns very cold. It is not a fashion statement but a necessity.
Success is often associated with luck and even people who are very talented seem to believe in fads based on some superstitious belief. We can often spot the baseball players wearing strange looking rope necklaces around their neck. This fashion trend has been sported by baseball players for over 10 years now. The reason why wearing rope necklaces have been such a famous fad is because many very famous and respected baseball players have worn this type of necklaces in important matches. Even in the biggest baseball sporting events like the World Series players have worn the rope necklace.
Bidding farewell to the dead is a well known custom and it consists of many age old traditions. Both the Christians and the Muslims are buried but pennies are put only at the gravestones of the Christians after burial. The desire to receive worldly goods even after death can be observed in many ancient cultures. For example in the Egyptian culture people used to make high and mighty tombs or the pyramids and fill them up with gold, jewelry and other luxury items so that they can live comfortably after passing away.
In nature nothing happens without a reason. Every substance is made up of atoms and molecules. There was a time when it was assumed that atom is the smallest part of a substance and it cannot be broken. With the progress of science we have come to know that each atom has three subatomic particles named electron, proton and neutron. The electron is negatively charged and the protons are positively charged. When an atom loses the negatively charged electrons it becomes positively charged and when new electrons enter an atom it becomes negatively charged.
The moon does not change shape. It is a satellite moving around the earth. Just like earth other planets of the solar system have their own satellites that move around them. Planets also have their own orbits and move around the sun. Earth has two different types of movements. It moves around its own axis once every 24 hours. We measure time with the help of the movements of the earth. The continuous movement of the earth and the moon creates some visual illusions. It seems that the moon is slowly disappearing from the sky leading to the creation of new moon and then it slowly comes back to its full moon avatar.
It looks eerie and even sinister the way some animal’s eyes glow in the dark. When photographed their eyes look like small balls of green or golden fire. Some animals have red or orange tints as well. Many horror stories use this phenomenon to scare us but not many of us know that the shining bright eyes of the animals are a purely biological incident. The animals that have to perform necessary tasks at night, such as hunting, need to see in the dark. This way their chances of survival increases. Dogs and cats have been domesticated but still they are nocturnal hunters and need to see in the dark.
Migration is not bound to a particular definition. We try to categorize particular movements as migration but it is not always possible. Animals change their habitats and shift their base from one place to another for different reasons. Like humans, animals also try to find the best facilities for themselves and their offspring. Generally when animals go from one place to another for some reason at a certain season, it is termed as migration. Animals and birds tend to follow a familiar route and always go to the same place for the same purpose. They are bound to the habits of migration but sometimes it is difficult to determine if their movements can be categorized under migration or not.
Nature has created us in such a way that we can perform all our tasks with the given organs. Evolution has taken care of the fact that our changing requirements are met by our capabilities. Cats are nocturnal animals that prey when darkness falls. They need to see both in daylight and in dark nights. A cat’s eye glows in the dark or at night so that it can see its ways around and can catch a rat or hunt for food. Whether you possess a pet cat or not, you have probably noticed how the eyes of cats gleam and shine in the dark and felt curious.
