Sexual dichromatism and the extent of male carotenoid-derived plumage coloration in breeding season North American passerine birds was analyzed by phylogenetic statistical methods. Passerines as a whole and five passerine subclades were analyzed by both independent contrasts and simulation methods. In passerines as a whole, carotenoids and sexual dichromatism are positively correlated irrespective of analysis method. In three of the subclades, the correlations are significant by a clear… Expand
