Several kind of animals do migration, the regular movement from one place to another place in order to holding out their life. Bird migration particularly draws much attention to the observer for century. Through migration, it can be seen how each species responds to develop and spread out into ecological niche that can provide the possible conditions to breed and raise young.

During the warm season, birds commonly travel to higher latitudes of the Northern Hemisphere that has optimal environment to breed, meanwhile during the non-breeding season they come back to lowest latitudes. Seabirds species are the only one that has different route migration to the higher latitudes of Southern Hemisphere to breed. Many species of migratory birds like arctic tern who flies 24,000 miles during migration, have trans-equatorial route, while they live at arctic regions in Northern Hemisphere during breeding season and spend the rest of the year at antarctic waters in the Southern Hemisphere. A ptarmigan, a form of arctic grouse, only have small distance migration who spend breeding season on arctic peaks and the winter season in neighboring valleys, and suffer patiently from coldest conditions.

During migration, Birds have different length of their ability to fly each day, it is more likely about six to eight hours and some birds undertake much longer from that depend on geographic feature in their route. Recently, researcher discovered about bird migratory navigation that drive them to specific destination. For nocturnal bird, which travel at night, use stars as their navigation but diurnal birds which travel at the day, use sun and geographic features as their navigation. Birds is predicted that has sense of time because they use sun and stars that move constantly at twenty-four hours.
