We reviewed the literature and compiled a comprehensive list of hybrids from the wood warbler family Parulidae, a diverse radiation of songbirds with divergent plumage traits. We used our compilation to analyze modes of inheritance in wing bar patterns and carotenoid coloration. Finally, we described an unusual hybrid from the...
