Szukana fraza: [Abstract = "Male birds often possess conspicuous or colourful plumage traits which are thought to function either in mate choice or as status signals which indicate their competitive ability. Many studies have confirmed that the size or expression of these traits is positively correlated with their success at attracting mates, their social dominance, or their fitness. However, relatively few studies have examined plumage variation in females, likely because it is much less pronounced than in males."]
