Do you know why animals migrate?

Animals are a group of living things. They generally feed on organic matter, can feel, can move, can move autonomously, or can move things. Animals also have a variety of behaviors that can be seen as animal responses to stimuli. Behavior is the science of animal behavior. One of the more famous behavioral theories is the instinct theory proposed by Conrad Lorenz. The following is a detailed introduction for you to take a look!

Animal migration is an unchanging instinctive response in nature. Every year we see many birds sweeping through the sky, and that's when we know it's time for them to migrate! So do you know why animals migrate? And what are the migratory animals?

I. Birds

After scientists' exploration, do you know why animals migrate?

About 18% of the world's 10,000 species of birds migrate due to changes in climate seasons. Most of these birds fly from north to south. The northern summer is usually the season when birds feed and breed, while winter is when they migrate south to warmer places. Arctic terns, for example, migrate from north to south a distance of about 12,000 miles each year.

II. Fish

Unlike birds, fish do not always migrate long distances, as they may end up in the same location. For example, if a fish inhabits a huge lake and eventually changes its habitat, the migration will be short, however, some fish travel hundreds of miles.

III. Insects

Insect migration usually occurs between winged insects such as dragonflies, butterflies, and locusts. For these two butterflies, the group that starts the migration is not the same butterfly that completes the journey. The reason for this is that the butterflies mate and reproduce in the process, so the new generation of butterflies is the one that completes the migration.

A good example of this migration is the famous migration of horned horses in the Serengeti National Park in Africa. In addition to the horn bills, other migratory species include zebras and antelopes. Interestingly, these groups can change their direction, though depending on environmental conditions.

V. Other groups

Other animals, such as cetaceans, including dolphins, whales, and porpoises also migrate. Migrating crustaceans include the astounding Christmas Island red crab, which migrates by the millions each year.

Animals migrate for the following reasons.

1. In search of food

Food is associated with reproduction, as most animals migrate to places where there is enough food for their offspring to survive and reproduce.

2、Hibernation

Hibernation is vital to the survival of some animals, and a good example of such an animals is the little brown bat. In the summer, these creatures live in the trees, while they migrate to caves in the winter to hibernate.

3. To escape from bad weather

Most migrating birds migrate because of the change of seasons. A perfect example of this is the Arctic Tern, which, due to its migration, this bird experiences two summers in a year instead of one.

4. Reproduction

One of the most common reasons for migration is for animals to find suitable breeding grounds for reproduction. Crustaceans, such as many species of crabs live in the deep sea but go to shallow waters to breed before returning to deeper waters. Amphibians like frogs and toads alternate breeding between breeding ponds and large lakes.

Experts in this field are still unsure how animals know the right direction, although a few theories have been proposed. One theory suggests that animals use landmarks to discern direction, and examples of such landmarks include rivers and lakes.

Other scientists believe that the sun and stars are used to determine direction. The keen sense of smell of some animals may also be how animals decide the right course, while others use the Earth's magnetic field.
