Metabolic rates of aggressive and submissive phenotypes are colour blind in the polymorphic Gouldian finch.

Abstract excerpt

Evidence from a number of species suggests that behaviours associated with social rank are positively correlated with metabolic rate. These studies, however, are based on metabolic measurements of isolated individuals, thereby ignoring potential effects of social interactions on metabolic rates. Here, we characterised three pertinent metabolic indices in the two predominant genetic colour morphs of the Gouldian...
