ABSTRACT Colorful traits play an important role in animal communication. Melanin‐based colorations are the most extended color animals and produced by two types of endogenous melanic pigments: eumelanins pheomelanins, last ones being least studied context The production pheomelanin requires a semi‐essential amino acid, cysteine, which is also used for synthesis antioxidant, glutathione. Hence, it has been proposed that glutathione may compete cysteine available organism. In case, pheomelanic predicted to be less intense when individual facing oxidative challenge, therefore, they would provide information on status bearer. Here, we experimentally evaluated this hypothesis using male Japanese quails ( Coturnix japonica ) as model study, species with pheomelanin‐based plumage breast cheeks. During feather growth, individuals were exposed one three possible conditions: Control (saline), challenge Escherichia coli lipopolysaccharide injections), or exogenous (paraquat injections). Contrary predictions, found that: (1) Birds from groups exhibited feathers after experimental manipulation, magnitude change did not differ among groups. (2) There was no effect treatments proportion reduced/oxidized glutathione, index status. (3) Lipid peroxidation lower birds paraquat experiencing stronger decline than other (4) Cysteine total levels decreased differences per group decline. Taken together results do support plays key at determining variation intensity colorations.
