Description	In the present study we compared the health- and stress-indicating capacity of melanin-based feather ornamentation and putatively carotenoid-based skin ornamentation in a single species – the grey partridge (Perdix perdix). In captive males, we firstly verified the carotenoid content of the red-coloured skin tissue behind the eye by chromatography (HPLC). Secondly, we assessed the individual health status of all males by examining differential leukocyte count, the frequency of immature erythrocytes, malaria prevalence and proinflammatory immune responsiveness to phytohaemagglutinin (PHA). Both the size of the melanin-based ornament and red chroma of the carotenoid-based ornament were related to the heterophil:lymphocyte (H/L) ratio. Hence, in the grey partridge both redness of the skin ornament and area of the feather ornament may serve as honest indicators of individual health and long-term stress. However, the two ornamental components were unrelated to each other, and the directions of their assoc In the present study we compared the health- and stress-indicating capacity of melanin-based feather ornamentation and putatively carotenoid-based skin ornamentation in a single species – the grey partridge (Perdix perdix).
