Comparison between 2019 and 2020 of number of birds banded

Figure 1 & 2. The total number of birds banded, recaptured, and encountered per month for 2020 and 2019 (data submitted to the BBL as of 2/12/2021). “Banded” refers to when a bird receives its unique federal band from a permitted bander. An “encounter” is any observation of a previously-banded bird, of which “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.
