- Brood merging and conspecific brood parasitism are common in some waterfowl and New World quails. A previously unrecognized, unusual similarity between them—female-biased natal philopatry and local relatedness—may enable indirect inclusive fitness gains in brood parasitism and merging. New World quails offer a rare possibility to test the role of female-biased natal philopatry in brood parasitism, brood merging, and other aspects of sociality and to help clarify the evolution of these traits.
