The migratory habits of animals 10 are fast and fast

The migratory animals are as follows:

Wild geeseIn 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 comes from the south in March every year, as if they had flown back from the south overnight, and they choose a family's house to build a nest and lay eggs, incubate eggs and brood. After a busy summer, when the weather cools down in late autumn, they fly to the warmer south to spend the winter.

SalmonSalmon, also known as salmon, is found in Alaska.

Every year, there is a great migration, where tens of thousands of salmon migrate from the sea to the river, gather around 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 flock to 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.

ReindeerReindeer are land mammals.

One of the longest migration distances. 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 reach the treeless Arctic Ocean.

Coast, then return the same way.

Migratory animals include monarch butterflies and wildebeests.

Swallows, Arctic terns, reindeer.

Wait. 1. Monarch butterfly: The monarch butterfly is a large butterfly that is very common in North America. Every autumn, a large number of monarch butterflies depart from the eastern and western parts of North America and fly south.

2. Wildebeest: Wildebeest lives in central and southeastern Africa, and will migrate westward in search of fresh forage during the dry season.

3. Swallow: Swallow is a typical migratory bird. After breeding, the young birds still follow the adult birds; And gradually integrate into large groups, in the first cold wave.

Arrival in the former Yugoslavia. Migrating for wintering, it is a "nomad" in the bird family.

4. Arctic Tern: The Arctic Tern is a light seabird that can fly long distances. When it is summer in the Northern Hemisphere, the Arctic Tern is in the Arctic Circle.

When winter comes, they will fly south to reach the Southern Hemisphere.

5. Reindeer: Reindeer, both male and female have horns, and the complex branches of the horns are an important feature of their appearance, mainly according to the weather conditions and the abundance of food to migrate.

Animal migration: Animal migration refers to the migration of animals over a certain distance due to breeding and other reasons. Broadly speaking, it refers to the movement behavior of animals from one area or habitat to another.

In a narrow sense, it refers to the group long-distance movement behavior of animals in a specific time and along a certain line in order to meet certain physiological needs in the process of evolution. The migration of animals is divided into cyclical and non-cyclical migrations.

Animal migration is mainly related to climate and food, such as geese, swans, and swallows among migratory birds, which migrate south every winter and fly back to the north the following spring. Among the animals, wildebeest antelopes will also migrate en masse on a large scale for food, and at the same time, some carnivores will follow closely, forming a spectacular scene of collective migration of a variety of animals. Fish also migrate en masse in order to reproduce and feed, for example, salmon swim upstream every year to spawn, tuna schools migrate en masse in search of food, and even baleen whales migrate en masse in pursuit of prawns.

Migratory animals can be divided into: migratory birds such as sparrows, magpies, house swallows, cuckoos, etc.; Fish migration such as herring, grass carp, silver carp, bighead carp, large and small yellow croaker, salmon, etc.; mammals such as reindeer; Insects such as butterflies, kings, etc.

It depends on where it is, such as Hoh Xil in China, where Tibetan antelopes migrate. The wildebeests, antelopes, zebras and flamingos of the African savannah are migratory. Caribou in Alaska in North America, red crabs in Christmas Island, sandhill cranes in Nebraska, sockeye salmon and king chatter in Alaska, and straw-colored fruit bats are among the migratory animals.

Migratory Behavior Migratory behavior is not an instinctive activity that is unique to birds. certain invertebrates, such as East Asian locusts, butterflies, etc.; reptiles, such as sea turtles, etc.; Mammals such as bats, whales, seals, deer, and certain fish species change their habitats over long distances during the season. 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. According to the presence or absence of bird migration activities, birds are divided into migratory birds and resident birds. Resident birds stay in their birthplace all year round and do not migrate, such as sparrows, magpies, etc.

Among the migratory birds, the birds that fly to breed in summer and go south in winter are called summer migratory birds, such as house swallows, cuckoos, etc.; Birds that fly over the winter and breed north in spring are called winter migratory birds, such as some wild ducks and geese.

Wait. 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.

There are three types of fish migration according to their purpose: reproductive migration, forage migration and wintering migration. Herring.

Grass carp, silver carp.

Bighead carp, large and small yellow croaker.

Salmon are reproductively migratory. Mammal.

The scale of migrations is huge, such as the reindeer's thousand-mile snow migration. Every winter, thousands of reindeer gather in huge herds of deer that move from north to south, towards the edge of the permafrost. The following spring, they headed north to the coast of the Arctic Ocean.

In April and May, the deer arrive in what they know to be secluded in the tundra, where they raise their young. Insect migrations can sometimes do wonders, most notably the Americas-native king butterflies, which fly from Central America to Canada in the spring and back to Central America in the fall, covering a distance of 4,500 kilometers over several months. Reason:

The migratory behavior of animals is an adaptation phenomenon that allows them to meet the environmental conditions they need for a particular period of life, so that the survival of the individual and the prosperity of the race can be reliably guaranteed. Thank you.

Migratory birds: such as house swallows,Cuckoos, oriolesFish: eels that live in freshwater migrate thousands of kilometers to the depths of the ocean to spawn, while salmon that live in the ocean swim thousands of kilometers in the opposite direction into the upper reaches of rivers to spawn.

Some fish only move short distances, such as the large yellow croaker, which migrates from Dongtou Ocean in northern Fujian Province to Lu Siyang in Jiangsu waters.

I think swallows, cuckoos have a habit of migrating, hope it helps you.
