* Alpha Codes are also known as 'banding codes' (not AOU codes, which are numeric) ** Safe dates represent a window when a singing male is assumed not to be in migration, and therefore on territory. Some atlases do not use safe dates, because they prefer (given present knowledge) not to assume migration or territorial status of all individuals. Safe dates generally apply to the Possible breeding category only when used. |
