Banding and encounter data are gathered and filed for the primary purpose of facilitating migratory bird research in North America. Therefore, all conservation agencies, universities, private organizations and individuals are encouraged to request banding and encounter information.
Files of banding data are maintained in Ottawa, Ontario by the Bird Banding Office of the Canadian Wildlife Service and at the Bird Banding Laboratory in Laurel, Maryland. Researchers in Canada should request information from the Canadian Wildlife Service while those in the United States should contact the Bird Banding Laboratory. In Canada, a data request form (Request for Data on Bird Banding and/or Recoveries), available from the Banding Office, should be completed. Normally data will be supplied free of charge for legitimate research purposes.
These files are updated annually in late August and are usually available for use in early October.
