What animals in nature migrate? Why do they migrate?

There are many migratory animals in nature, from fish, birds, and mammals.

When it comes to insects, there are some species that migrate, and the purpose of migration is different. Here are a few examples to illustrate the purpose of animal migration:

When it comes to migration, the first thing that comes to mind is migratory birds, and the common house swallow.

It is a type of migratory bird. Migratory birds are a type of bird that regularly migrates with the seasons, and some of them fly thousands of kilometers to migrate. Birds migrate mainly in search of wintering grounds, to escape the cold winters, and to get more food during the winter months.

Bird migration routes are generally similar, but the locations of each migration are not necessarily the same. Birds are also one of the most common migratory animals. Similar to the North American goldenrod butterfly, this insect also undergoes large-scale migrations with the seasons.

There are nomads among the human race.

They live a life of migration and migration. In fact, their way of life is the animal they graze, and they migrate with the animals. Animals that live on the grasslands migrate according to the changes in their food on the grasslands.

The most famous of these is the wildebeest on the African savannah.

In search of food, chasing the great migration of the pastures. It was a shocking sight, as the animals of the steppe migrated in search of enough food and water.

Fish also migrate, and some fish return to their birthplaces to breed, so the concentrated migration for breeding is called migration. For example, Qinghai Lake.

Among the fish.

and the famous salmon.

This is the case. Of course, fish are not the only species that migrate for breeding, sea turtles live in the sea.

The same is the case. Usually sea turtles are scattered all over the ocean, but once it is breeding season, the female turtle will gather on the beach where she was born, climb up to the beach again to lay eggs and breed, and once the eggs are laid, they will disappear into the sea again.

Migrating animals are naturally far more than just the ones mentioned above, but the purpose of animal migration is roughly due to these few reasons, migrating for climate, food, and reproduction.

First, elephants, secondly, swallows, third, East Asian locusts, fourth, fish, fifth, reindeer, they all migrate for foraging or mates, or because of the climate.

Migratory birds, some fish, African elephants, etc., all migrate because of seasonal climate change, or because of water sources and food.

Wildebeest, migratory birds, geese, swallows, and many fish migrate. In order to avoid the harsh environment, survive and eat by yourself.

Wildebeests, migratory birds, geese, swallows, and many other fish, all of which migrate. In order to avoid the harsh environment, allow yourself to survive and find something to eat.

The migratory animals are as follows:

1. Wild goose:In order to survive, geese migrate back and forth between breeding grounds and wintering grounds every year, and their migration has a strong time rhythm, and the ancient Chinese have long noticed the relationship between migratory bird migration and seasonal changes.

2. Swallow:Swallows are a migratory bird that flies in from the south in March, as if they had flown back from the south overnight, and they choose a house to nest in, then lay eggs, incubate eggs and raise broods. After a busy summer, when the weather cools down in late autumn, they fly to the warmer south to spend the winter.

3. Salmon:Salmon, also known as salmon, is a spectacular sight to be seen in Alaska every year, when tens of thousands of coarse salmon migrate from the sea to the river, gather by the river to spawn and die.

4, Butterfly King:This large orange-brown butterfly is able to migrate long distances as the seasons change. Every spring, the butterflies always fly in droves from Central America all the way to Canada; In the fall, it returns to Mexico by the same route, a journey of 4,500 kilometers that will take several months.

5. Reindeer:Reindeer are one of the longest migratory mammals of the land mammals. Reindeer do not fly as described in fairy tales, and they may be more than willing to have such abilities themselves.

In fact, reindeer have to migrate 6,000 kilometers. They pass through spruce forests and mountains in the north to the treeless shores of the Arctic Ocean, and then back the way they came.

Animal migration is an adaptive behavior that changes periodically in environmental factors. Seasonal changes in climate are the main reasons for animal migration. Due to climate change, there are often food shortages, forcing animals to migrate to other areas where food is abundant.

The migration of animals is regular, directional, and mostly carried out in large groups. Bird migrations occur periodically each year between breeding and wintering areas, mostly between the northern and southern hemispheres, and a few between the east and west. And the scale of mammal migrations is enormous, such as the reindeer's thousand-mile snow migration.

Animal migration refers to the movement of animals over a certain distance due to breeding, foraging, climate change, etc. There are two types of animal migration: cyclical and non-cyclical. Migratory animals are:

1. Invertebrates such as East Asian locusts and butterflies.

2. Sea turtles and other reptiles.

3. Mammals such as bats, whales, seals, and deer. The scale of mammal migrations is enormous. For example, in the winter of the reindeer, thousands of reindeer gather into a huge herd of deer and then move from north to south towards the edge of the forest tundra.

The following spring, the deer made their way north to the Arctic coast until they reached what they knew to be secluded in the tundra.

4. Fish. Some fish species have seasonal long-distance habitat changes. The migratory activity of fish has a proper name called migration.

Most fish species are migratory, with only a few species that do not exhibit regular migration. According to the purpose, fish migration can be divided into three types: reproductive migration, forage migration and wintering migration. Herring, grass carp, silver carp, bighead carp, large yellow croaker, small yellow croaker, and salmon all migrate reproductively.

The migration of animals is regular and directional. And most of them are integrated and carried out in large groups.
