Total by year and by species

Total banded raptors by species by year from IBO’s Boise Peak and Lucky Peak banding stations combined. Rank represents the current year rank out of a total of 33 years (counting 2025). Note, the first three years rank lower as there the trapping protocol varied (different sites, different, hours, etc.). Also, starting in 2014, we shifted the starting date 10 days earlier.
