The breeding behavior of goldeneyes in eastern Schleswig-Holstein has been recorded intensively since 1971. Since last 44 years this population showed that nestboxes were often used by two females within the same breeding season. In addition, individual females successfully incubated replacement clutches after losing their first clutch during incubation. This behavior has only rarely been described in detail for goldeneyes. Influencing factors and causes of this behavior are probably a continuous, climate-driven extension of the breeding season and possibly an increasing breeding density. Qualities of the affected females as well as effects on fitness are discussed and future perspectives of this behavior are shown. At least in northern Germany Goldeneyes appear to be able to achieve a higher reproductive rate in a prolonged breeding season through better use of their limited nesting space and by renesting, and thus adapt to the consequences of climate change.
