In order to assess the level of confidence in the link made, as well as the time and effort taken to make the link, the Secretariat introduced a tag recapture link status code to identify the level of effort involved in linking a tag recapture to its tagging event. For the 2011 season 673 tags have been returned; 37% provide an exact match with tag numbers held in the database, 22 % provide an exact match with tag numbers but had inconsistent ancillary data . For those tags that did not provide exact or unique matches only 63 (9%) could not be successfully linked using additional information.
