What kind of animals live in migration?

Seasonal migrations occur in many species of insects, birds, marine mammals, and large herbivorous mammals. These migrations often provide the animals with more favorable conditions of temperature, food, or water. Many birds and a fewbats of cold and temperate regions migrate to warmer areas during the winter. Herbivores of cold regions, such aswapiti (elk), caribou, andmoose, have summer and winter ranges; many herbivores of warm regions, such as the African antelopes, migrate seasonally to avoid drought. These migrations may involve a change of latitude, of altitude, or both.
