Abstract
In some species of polygynous songbirds, males assist in feeding nestlings of their first (primary) female but ignore offspring of subsequent (secondary) mates. A number of adaptations important in minimizing the disadvantages of a secondary status in female Bobolinks (Dolichonyx oryzivorus) have been discovered.Keywords
