Brood Parasitism and Nest Takeover in Common Eiders
Abstract Conspecific brood parasitism (CBP) is an alternative breeding tactic that occurs in many brood‐tending animals and can have important fitness effects for both host and parasite. We use protein fingerprinting of egg albumen to distinguish the eggs from different females and to estimate the f...

In 11 (41%) of the mixed clutches another female laid before the host started laying, corroborating the hypothesis that takeover of nests started by other females accounts for many of the mixed clutches in this population.
