Carotenoid-based epaulettes reveal male competitive ability: experiments with resident and floater red-shouldered widowbirds (2003, background): “Similarly, in the field, males with experimentally enlarged epaulette signals successfully established territories and received fewer aggressive intrusions from conspecifics than males with blackened or reduced signals ( Pryke & Andersson 2003 ).”
Melanin- versus carotenoid-based sexual signals : is the difference really so black and red? (2006, background): “…widowbird, Euplectes ardens, REVIEW 759 and the red-shouldered widowbird, Euplectes axillaris, the expression of the carotenoid-based red plumage is a status signal and predicts the outcome of experimental dominance interactions between males (Pryke et al. 2002; Pryke & Andersson 2003).”
Seeing red: morph-specific contest success, and survival rates, in a colour-polymorphic agamid lizard (2007, result): “This concurs with a large number of studies across taxa, for example, Gouldian finch, Erythrura gouldiae (Pryke & Griffith 2006), widowbirds, Euplectes axillaris ( Pryke & Andersson 2003 ), cichlids (Evans & Norris 1996) and human sports (Hill & Barton 2005).”
Female American goldfinches use carotenoid-based bill coloration to signal status (2009, background): “Among birds, there are only a few known examples of such signals, most of which have been found in males (Pryke et al. 2001; Pryke and Andersson 2003; Pryke and Griffith 2006; Griggio et al. 2007; see Murphy et al. 2009 and Crowley and Magrath 2004 for examples in females).”
Armaments and ornaments in the rock sparrow: a possible dual utility of a carotenoid-based feather signal (2006, background): “…for each morphological trait measured in this study (i.e., yellow patch size; body size, expressed as wing length; tarsus length; body mass) by calculating the difference in feeding time and the difference in each morphological trait between each pair of males used in each dominance trial.”
The interrelationships between resource-holding potential, resource-value and reproductive success in territorial males: How much variation can we explain? (2008, methodology): “More common, but still found in only four studies (Lebas 2001; Andersson et al. 2002; Forstmeier 2002; Pryke and Andersson 2003a, b), was the use of PCA to distil several measures of one trait-type (e.g. structural) to a single variable representing, for example, body size (e.g. tarsus, culmen and…”
