Description
Summary: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. ... : All islands were visited over the span of 1–2 weeks every breeding season each year, depending on weather and the number of people available. For Brokey and Purkey, nests were counted and located by 6–12 and 2–5 people per year, respectively. The only years missing are the years 1946–1950 in the Brokey archipelago. ...
