Bird migration is interesting object to be observed, because migration is a good example to know nature's response for species to make change into all possible place for living. There are two kinds of birds, land bird and seabird. Both of them migrate from one half of the earth to the other half when the breed and the rest period come. However, the seabirds travel to the southern hemisphere for nesting while the land birds are in the northern hemisphere. Based on their ways to migrate, bird migrations consist of two types: nocturnal migrants and diurnal migrants. Nocturnal migrants, traveling at night, navigate by looking at the star, and when clouds obscure the sky, they may stop flying. Diurnal migrants, migrating during the day, navigate by looking at the sun and landforms.
