Bird Encounters from 2021
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 band

Banding and Encounter of an Pacific Golden Plover
A Pacific Golden-Plover (Pluvialis fulva), like the one pictured, was originally banded with a USGS federal leg band in Alaska and then encountered in Japan several months later. Currently the BBL is working together with Japan's banding scheme to ensure bird movement data, like this, gets recorded from both schemes.
