Spatial relatedness and brood parasitism in a female-philopatric bird population
The spatial structure of relatedness between individuals in a population can be crucial for social selection and evolution. Here we analyze a female alternative reproductive tactic, conspecific brood parasitism, in relation to spatial relatedness among females in a Baltic Sea population of the commo...

The spatial structure of relatedness between individuals in a population can be crucial for social selection and evolution.
