Comedy starring Steve Martin, Jack Black and Owen Wilson as three men in different stages of life competing to become champion birdwatchers. Stu (Martin) is a successful business executive on the brink of retirement. Brad (Black), the youngest of the three, works as a computer programmer but lacks direction and focus in his life. Meanwhile, the obsessive and unscrupulous Kenny (Wilson) will stop at nothing to hold onto his title of World's Greatest Birder. As they travel the length and breadth of North America as participants of the 'Big Year' competition, in which birders compete to spot the greatest number of bird species in the United States over the course of one year, the three men discover as much about themselves and each other as they do about America's bird population.
