Abstract
Since the previous document concerning this work (document FISHERIES/2011/SWG-PEL/01) was submitted, tag-sighting data for adult birds for earlier years has been included in the model likelihood as described in document FISHERIES/2011/SWG-PEL/02 (after consultation with the holders of the tagging data, it was confirmed that our previous interpretation of the capture history database was appropriate). Also, some immigration has been allowed over the period 1989 to 1999 as the additional tag-recapture data provide the further information required to render this immigration estimable.
