The health signalling of ornamental traits in the Grey Partridge (Perdix perdix)

Popis výsledku v původním jazyce

Birds express various secondary ornaments that can indicate individual condition and health. Amongst these, red-coloured carotenoid-based ornaments are supposed to be particularly valuable predictors of individual quality, due to their sensitivity to oxidative stress. Nevertheless, melanin-pigmented traits might also signal health and immune functions. Both types of ornaments may be either skin-based or feather-based, each differing in their dynamics. 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), a vulnerable avian species of the European agricultural landscape. 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
