“…Numerous studies have identified male plumage traits associated with strong female preferences and increased fitness (Byers et al, 2010; Møller, 1988; Rodríguez et al, 2006; Ryan et al, 2019; Searcy & Andersson, 1986). In contrast, relatively few studies have found relationships between female visual signals and fitness proxies, but see: (Amundsen et al, 1997; Bulluck et al, 2017; Cain & Ketterson, 2011; Jawor et al, 2004; Pap et al, 2019). Likewise, many studies have examined the fitness correlates of male song (Catchpole & Slater, 2003; Gil & Gahr, 2002), but only a handful have looked at how female song impacts fitness (Brunton et al, 2016; Cain et al, 2015; Kleindorfer et al, 2016b; Krieg & Getty, 2016a).…”
