To understand their ultimate signaling functions, it is important to identify the proximate mechanism promoting variation in coloration. Carotenoid‐based colors combine structural and pigmentary components, but the importance of the contribution of structural components to variation in pigment‐based colors (i.e., carotenoid‐based colors) has been undervalued. In a field experiment with great tits (Parus major), we combined a brood size manipulation with a simultaneous carotenoid supplementation in order to disentangle the effects of carotenoid availability and early growth condition on different components of the yellow breast feathers. By defining independent measures of feather carotenoid content (absolute carotenoid chroma) and background structure (background reflectance), we demonstrate that environmental factors experienced during the nestling period, namely, early growth conditions and carotenoid availability, contribute independently to variation in yellow plumage coloration. While early growth conditions affected the background reflectance of the plumage, the availability of carotenoids affected the absolute carotenoid chroma, the peak of maximum ultraviolet reflectance, and the overall shape, that is, chromatic information of the reflectance curves. These findings demonstrate that environment‐induced variation in background structure contributes significantly to intraspecific variation in yellow carotenoid‐based plumage coloration.The experiment was financially supported by the Swiss National Science Foundation (grant 31-53956.98 to H.R.) and conducted under a license provided by the Ethical Committee of the Office of Agriculture of the Canton of Bern, Switzerland.
