Whereas animals that live in countries that have hot and humid environment whole year like Tanzania, Kenya, Nairobi most parts of African countries doesn’t migrate because they don’t need to, the temperature remains  constant.

Migration for breeding?

Up till now we learned that animal migrate to other countries for survival but do animals also migrate for other causes such as breeding to other parts of the world. The answer to this question is yes they do, because breeding requires warmth so each time when breeding season arrives several animals like fishes and Whales, Seals and other creatures move towards warm waters in order to breed and they stay with them for years until the eggs hatch and are safe enough to live on their own. This process is followed globally.

Whereas animals that are looking for warmer climates will have to travel south which will take long distance. The perfect example for long distance migratory animals is the swallows which are famous for travelling the longest distance which is 6,500 miles up to 10500 km.

This type of distance will take long time and high sources of energy to keep going. It’s very outstanding but will take hard work.

It is possible that the birds and other animals have a strong sense of magnetic fields so they move according to it

Survival of winter without migration

The process of migration is followed by various animals in order to survive cold but there are numerous animals that choose not to migrate to warm places and find ways to keep themselves warm. There are several methods to defy cold and animals have adapted them. Let’s learn about the practices and actions they take in winter months.


Bears are well known for hibernating as they waste away half of their life sleeping in a cave. They do it by decreasing their body temperature gradually while slowing down their breathing and even heart rate. Bears are known for hibernating around 6 months but they keep themselves alert and will take a break from their hibernation and check around if they sense any danger.

Apart from bear several animals take hibernation to another level for example bat they take gaps up to an hour each time they breath also they can lower their temperature almost to freezing point. 

There are many interesting facts about animals hibernating if you were shocked about birds know the exact time to migrate and how they navigate you’ll be more intrigued by the bears because they sense the winter coming even before the weather turns cold and starts eating excess food to store it when they are in hibernation. 

Modification instead of Migration

There are also various animals that choose not to move around and instead have to do some modifications like having warm feathers or a fluff out so they won’t freeze to death and they look super adorable in those fluffy feathers. These animals include turkeys, hawks, owls etc.

They store large amount of foods in the hideout. The main aim of this hideout is to protect the queen from dangers of cold, the queen is important because it carries the next generation and if anything happens to her the eggs will be wasted.

Prepared for death.

The life span of certain animals is limited on the basis of seasons and when those seasons are about to arrive the following animals such as gnats Field Crickets, hornets, hopper do not survive in winter so they prepare themselves for death and before that they lay a lot of eggs to guarantee the next generation.

Animals like larva have a backup mechanism for conditions that are extreme such as in winter they maintain their body temperature and are able to live by producing alcohol in its blood so they won’t freeze.
