In the case of Agelaius phoeniceus, sexual selection acts strongly on males and affects just those traits in which males differ most from females, viz. size, aggressiveness, plumage, and song. The action of sexual selection on male redwings is mediated through female choice and competition among males. There is also some evidence of sexual selection acting on females, through the process of female competition.-from Author
