North American bird banding program longevity records

Longevity in wild birds refers to the longest-lived individual of any particular species. This measure of age can reflect important life history traits and identifying differences in longevity patterns between species can reveal unique threats or conservation needs. Because it requires the identification of individual birds, longevity can usually only be measured through banding or marking of individuals. A bird’s age can generally be determined at the time of banding and then recalculated whenever the bird is subsequently recovered, recaptured, or resighted. The North American Bird Banding Program (NABBP), comprised of the U.S. Geological Survey Eastern Ecological Science Center Bird Banding Laboratory (BBL) and Canada’s Bird Banding Office (BBO), curates a vast dataset of all North American bird banding records, as well as subsequent encounters of banded birds reported by banders and members of the public. Although not all bird populations are banded equally and band encounters are only reported voluntarily, the NABBP is thus uniquely situated to catalogue and report longevity records for bird species under our purview.
