Wintering Areas and Recovery Rates of Brünnich’s Guillemots Uria lomvia Ringed in the Svalbard Archipelago
We mapped wintering areas and estimated the recovery rates of Brünnich’s guillemots (thick-billed murres) ringed in Svalbard during 1954–98. Recoveries were reported from Iceland, Greenland, and Newfoundland. An intensive hunt occurs annually off Greenland and Newfoundland, and more than 95% of the...
