Carotenoid-based ornaments are often considered reliable(honest)individual condition signals because their expression implies physiological costs unaffordable for low-quality animals(handicap signals).Recently,it has been suggested that efficient cell respiration is mandatory for producing red ketocarotenoids from dietary yellow *** implies that red colorations should be entirely unfalsifiable and independent of expression costs(index signals).In a precedent study,male common crossbills,Loxia curvirostra,showing a red plumage reported higher apparent survival than those showing yellowish-orange *** plumage redness in this species is due to ketocarotenoid accumulation in ***,we correlated the male plumage redness(a 4-level visual score:yellow,patchy,orange,and red)and the body morphology in more than 1,ooo adult crossbills captured in 3 Iberian localities to infer the mechanisms responsible for color evolution.A principal component analysis summarized morphometry of 10 variables(beak,wing,tarsus length,etc.).The overall body size(PC1)and the length of flight feathers regarding body size(Pc3)showed significant positive relationships with plumage *** redness was barely correlated with bill shape measures,suggesting no constraint in acquiring carotenoids from pine ***,large body sizes or proportionally long flying feathers could help carotenoid acquisition via social competition or increased foraging *** longer flight feathers might also be associated with a specific cell respiration profile that would simultaneously favor flying capacities and enzymatic transformations needed for ketocarotenoid *** a phenotypic profile would agree with the hypothesis of ketocarotenoid-based colors acting as individual quality index signals.
