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.

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.

Appendicitis is related to gastrointestinal diseases, the first habit usually does not pay attention to eating habits, it is easy to lead to the chance of appendicitis, the second habit such as overeating, which will lead to a decrease in the stomach's tolerance, and the third habit of eating some spicy food, which will increase the chance of appendicitis.
