How to request bird banding data

The North American Bird Banding Program database holds over 70 million banding records and over 3 million encounters dating from 1908. Birds banded in Canada are most often encountered in the USA, Canada and Mexico but they are regularly encountered in Central and South America, the Caribbean, Greenland and Iceland and occasionally encountered in Russia, Europe, Africa and Asia.

While banders are encouraged to analyze and publish the results of their banding activities, the Banding Office also encourages use of banding data by others. These data are gathered for the primary purpose of facilitating migratory bird research in North America and are available free of charge upon request, from the Banding Office.

Bird banding data have been gathered at a significant cost to the many banders who cooperate in the North American Bird Banding Program. Banders have certain proprietary interests in the data they produce. To protect their interests, policy and data release statements are included with each request, describing current limiting criteria for data use.

Pre 1960’s data are summarized but are not generally included in data requests unless specifically requested. Information may be withheld for species of conservation concern such as species at risk. Additional justification and approvals may be required to receive these data.
