GrrlScientist presents Pretty Boys Have All the Chicks posted at Living the Scientific Life, saying, "Everyone is familiar with sexual dichromatism in birds; you know, the gorgeous, colorful male who is paired with the drab female or two. It has been observed in birds that, when males and females differ dramatically in appearance, the females are preferentially mating with a few "pretty boys"; those that have elaborate plumage colors or ornamentation. As a direct result of female breeding preferences, these "pretty boys" sire more offspring than those males with less colorful plumage, thus driving the evolution of sexual dichromatism in the population. This behavior concurrently drives evolution of a polygynous breeding system in the population. But what about those birds that are monogamous yet still show strong sexual dichromatism? How did they get to be that way?"
