Effects of tail chroma and nitrogen ratios on greater covert colour values. Relationship between A) Tail chroma values and residual greater covert chroma values that control for the effects of sex, age and nitrogen isotope ratios in greater covert feathers, and B) Nitrogen isotope ratios in greater covert feathers and residual greater covert chroma values that control for the effects of sex, age and tail chroma values.
