Canadian Wildlife Service - National SiteNational Wildlife Research CentreMigratory Bird Populations Division - Bird Banding Office Reporting Banded BirdsReporting Goose CollarsResearchers who study goose populations will often mark individual birds with goose collars of various colours and alphanumeric codes. Researchers use different colours to indicate the flyway or a special project. Because geese aggregate on wintering grounds, it is possible to see several colors in one area. Collars are large enough that they can be easily read from a distance with binoculars or a telescope. When recording information from a collared goose, the more information that you can provide, the more likely the individual bird can be identified or marking project determined. It is important to take care when recording the information as codes may be vertical, horizontal, or some combination. Providing a sketch of the collar with character placement can be useful or stating whether the numbers or letters run vertically or horizontally can also improve accuracy of reporting.Important information to record: * Collar colour, code, code colour, and orientation of codes on the collar * Date the bird was observed * Exact location the bird was observed * Species age and sex of the bird if known * Your name, address, telephone number and e-mail addressReport your observations by calling the Bird Banding Office toll-free 1-800-327-2263 (1-800-327-BAND), by sending an e-mail message to the Bird Banding Office, or by writing a letter to:Bird Banding OfficeNational Wildlife Research CentreCanadian Wildlife ServiceOttawa, Canada K1A 0H3You will receive a certificate of appreciation telling you where and when the bird was collared, its age, whether it was male or female, and who collared it.
