The effect of coccidial infection on iridescent plumage coloration in wild turkeys (2005, background): “Instead, expression of melanin pigments seems to relate to the social status of the individual (Senar 1999; McGraw et al. 2003).”
How feather colour reflects its melanin content (2005, background): “Several hypotheses have been proposed for how melanin colours may signal quality, involving hormonal (Buchanan et al . 2001), dietary (McGraw 2003) or social ( McGraw, Dale & Mackillop 2003 ) mechanisms, but to date there are few experimental tests of or support for any of these.”
The antioxidant function of many animal pigments: are there consistent health benefits of sexually selected colourants? (2005, background): “Several experimental studies have probed aspects of ornamental colour development in animals (particularly for melanins), but rather than address the benefits of pigmentation, they instead have targeted the costs of coloration (reviewed in McGraw et al. 2002, 2003).”
Testosterone and melanin-based black plumage coloration: a comparative study (2008, background): “Thus, T-dependence of bib size may well explain why larger-bibbed males are more dominant throughout the year (reviewed by Senar 2006) and why males that interact more aggressively during molt grow larger bibs (McGraw et al. 2003).”
Dietary amino acids influence plumage traits and immune responses of male house sparrows, Passer domesticus, but not as expected (2005, background): “Our concern about this was confirmed by evidence that aggression can affect the development of the bib (McGraw et al. 2003).”
Assessing the function of house sparrows' bib size using a flexible meta-analysis method (2007, background): “The variation we observe in the bib size of house sparrows may be largely due to environmental factors during and prior to a molt, such as nutritional conditions (Veiga and Puerta 1996; Poston et al. 2005), rearing conditions (Griffith et al. 1999a), social conditions ( McGraw et al. 2003; Jensen e”
Diet quality affects an attractive white plumage pattern in dark-eyed juncos (Junco hyemalis) (2007, background): “A similar phenomenon was demonstrated in house sparrows (Passer domesticus), in which groups that were more aggressive during molt grew larger chest badges, a melaninbased trait that is used as status signal (McGraw et al. 2003).”
Testosterone upregulates lipoprotein status to control sexual attractiveness in a colorful songbird (2006, methodology): “We measured plasma T, plasma cholesterol, plasma carotenoids , and beak color in a captive, nonbreeding population of 13 males (see McGraw et al. 2003a for housing conditions and diet).”
Feather-Degrading Bacteria: A New Frontier in Avian and Host–Parasite Research? (2008, background): “…Bacteria and Feather color exPression Feather color can communicate information about the nutrition (Hill and Montgomerie 1994), immunocompetance (Saino et al. 1999), endoparasite load (Hamilton and Zuk 1982), age (Siefferman et al. 2005), and dominance (McGraw et al. 2003) of the signaler.”
Dietary mineral content influences the expression of melanin-based ornamental coloration (2007, unknown): “There is a large literature on how hormonal (e.g., testosterone, luteinizing hormone; reviewed in Ralph 1969; McGraw 2006), genetic (reviewed in Roulin 2004; Mundy 2006), and social (Korzan et al. 2000; McGraw, Dale et al. 2003; Tibbetts and Dale 2004) processes shape melanin color expression in a”
MELANIN ORNAMENTS, HONESTY, AND SEXUAL SELECTION (2003, background): “…mentioned, individuals with experimentally altered melanin ornaments frequently experience aggression from unaltered conspecifi cs. House Sparrows that interact frequently with conspecifi cs during molt grow larger badges (McGraw et al. 2003), but whether badge color changes is not known.”
Testosterone, dominance signalling and immunosuppression in the house sparrow, Passer domesticus (2003, background): “This result is supported by the recent finding that seasonal increases in bib size are affected by the number of aggressive interactions prior to the onset of moult, probably through the effects of testosterone ( McGraw et al. 2003 ).”
