Detailed explanation-1: -Our climate is changing and this change is affecting wild birds and animals. Disrupted breeding, barriers to migration and increased disease transmission are just some of the threats migratory species face from Climate Change.

Detailed explanation-2: -Animal migration is the large-scale movement of a species from one place to another. Most species migrate during specific seasons, in search of food or water, or for mating reasons.

Detailed explanation-3: -migration, in ethology, the regular, usually seasonal, movement of all or part of an animal population to and from a given area. Familiar migrants include many birds; hoofed animals, especially in East Africa and in the Arctic tundra; bats; whales and porpoises; seals; and fishes, such as salmon.

Detailed explanation-4: -Global warming also influences the routes of many migratory birds and their annual migration rhythm. A lot of migratory birds change their routes, shorten or completely cancel their journey as a result of changing temperatures.

Detailed explanation-5: -Animals migrate so that they can survive; it is a form of adaptation. Many habitats have wet/dry or cold/hot seasons and are therefore difficult to survive in all year round, so the animals have to either move away (migrate) or hibernate in the winter.
