How can I get bird banding and encounter data, and longevity records, from the Bird Banding Laboratory?

Banding and encounter data are available for research purposes. Individual banding data records exist electronically starting in 1960. Pre-1960 banding data are available only for birds that have been encountered. Individual encounter data are available from 1913. To make a data request go to the Banding and Encounter Data page.

Longevity records shows recorder holders for each bird species and bird species group (wild birds only) for North American and Central Pacific species known to the BBL. These record holders come from data collected across 100+ years. The list shows record holders (which were verified by the lab) and does not provide a list of the oldest birds within in these species.
