Abstract

Common eider (Somateria mollissima) nest counts in Breiðafjörður Bay in West Iceland in the two archipelagos Brokey (95 islands over 123 years) and Purkey (39 islands over 27 years) along with size information on islands and their distance from mainland. Information on presence/absence of invasive American mink (Neogale vison) and native arctic fox (Vulpes lagopus) as well as the Atlantic Multidecadal Oscillation index (AMO) is provided, too.
