Animals move from one place to another because of climate changes, the availability of food, or to ensure reproduction. Another reason for migration would perhaps be to complete a lifetime (for example; salmon). For more information: http://encarta.msn.com/encyclopedia_761557464/Animal_Migration.html#s1
In some cases it is to congregate at a particular spot for breeding purposes. Salmon and eels migrate for this reason.
Also in the case of most birds it is to maintain an amenable environment to live in.
In most cases its a bit of both.
There are different types of migration, such as weather migration, mating migration, and food migration. Weather migration is when animals migrate to a different are than what they're living in if it is eaither too hot or cold. Mating migration only applies to animals that live together with the same sex only. When mating season comes, the animals migrate until they meet each other and then they mate. Food migration is when the are that an animal is living in runs low on food. So, the animal migrates to a different are that has more food.
Migration allows animals to avoid unfavorable conditions, follow resources, allows for year-round activity (avoid hibernation), and may help complete the reproductive cycle.
It can benifit by finding new mates, getting to warmer land if their home land is too cold, or even finding new food. Whe
to spend spring and summer in cooler migrate to warmer climates in the fall
Animals migrate not people.
It is known as migration.
Cattle drives are allegedly responsible for the northward migration of the pestilent Mesquite tree in the American Southwest.
In the living world, the movements are diverse. The movement of animals is a migration. For example, there is seasonal migration of migratory birds or vertical migration of soil insects. The movement of single-celled organisms is a taxis (movement of the entire body to or from the stimulus). Movement is not always associated with the ability to move, so the pollen of plants is carried by the wind or insects. Cell movements are most often associated with the organelles of movement (flagella, cilia), but they can also move passively or with someone's help.
A migration.
A Reproductive Migration is.. movement from animals from one place to another.
The instinctive movement of a population refers to the collective behavior or migration patterns that are inherent and natural to a group of organisms. It often involves factors such as seasonal changes, resource availability, mating habits, or environmental pressures that influence the movement of individuals within a population. This behavior is typically driven by survival instincts and genetic programming.
migration of animals
mostly birds but there are other animals
Migration protects animals in a variety of ways. For example, birds may migrate as it becomes too cold for them to hunt.
animals don't adapt to migration they are born knowing how to do it the act is only learned if there habitat has been or is being destroyed
animals do both
geese
Animal migration or Migration in animals
Migration of animals is usually seasonal and seasons are related to earth motion .Most animals migrate before and after winter to avoid winter .
The two types of migration are voluntary and involuntary. An example of voluntary migration would be birds flying south for the winter, involuntary migration would be animals leaving a decimated rainforest.
