Detailed Description

A map of where previously-banded birds were found in 2021, in pink, a total of almost 120,000 encounter and recapture records. An “encounter” is any observation of a previously-banded bird, of which a “recapture” is a special case where the bird is captured by a permitted bander, either the person who originally banded the bird or someone else.
