Summaries of Banding and Encounter Data

• Use this form to retrieve total numbers of birds banded and encountered by species, country, year, and state/province.


• Certain records are not included in these totals due to the fact that they contain inexact data. Examples include unknown encounter dates and reports of bands found or purchased.


• Encounter counts listed by state/province are those that were encountered within the state/province in the designated year regardless of where or when they were banded.


• For countries other than United States and Canada, data are summarized only at the country level; states or provinces are not selectable.


• Because bands are occasionally replaced on birds, the counts of banded birds may be slightly inflated by birds who have worn more than one band.


• There may be a slight delay in retrieving the data.


• The data on this page are updated every Monday.
