World Migratory Bird Day celebrates bird migration in America. Bird migration is a regular seasonal movement often north and south along flyway between breeding and wintering grounds. Some birds are obligate, meaning they travel by instinct, the same time every year. Other birds are facultative, which means they migrate more with conditions of the moment, they are more flexible by days or weeks, depending if the weather warm or cold.
