Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds , mammals , fish , reptiles , amphibians, insects , and crustaceans .
Wildebeest migrating in the Serengeti. Migration, in ecology, is the large-scale movement of members of a species to a different environment.Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal migration is the best known type.
Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.
The rate of emigration has continued to grow, reaching 280 million in 2017. [15] In Armenia, for example, the migration is calculated by counting people arriving or leaving the country via airplane, train, railway or other means of transportation. Here, the emigration index is high: 1.5% of population leaves the country annually. [16]
According to Lawrence Venuti, every translator should look at the translation process through the prism of culture which refracts the source language cultural norms and it is the translator’s task to convey them, preserving their meaning and their foreignness, to the target-language text. Every step in the translation process—from the ...

The role of migration in gene flow has also been studied in many species. [7] Parasite loads affect migration. Severely infected individuals are weak and have shortened lifespans. [8] Infection creates an effect known as culling whereby migrating animals are less likely to complete the migration. This results in populations with lower parasite ...
