My Big Year is your personal radar for birds you haven’t seen — on Big Years, Big Days, and Life Lists, across the places you actually bird.

Built by a retired software developer, it was his tool for a Maine Big Year record (2021) and later helped him and his wife reach 708 species in the Lower 48 (2024). This release opens that workflow to birders across major regions — not just one state.

List where you bird

United States & Canada (states, provinces, counties / equivalents)
ABA & ABA Continental
AOU (37 countries & territories)
Europe (50 countries)
South America (16 countries)
Create multiple lists at once. Mark a bird seen at the smallest circle and watch it ripple to higher lists you track.
