Shank Color and Barred Plumage in Columbian-Colored Chickens
Poultry Science, 1955 Abstract MANY females produced from crosses of barred columbian, (B S e), males and red, e, females develop a greenish shank coloration by the broiler age of 8 to 12 weeks after hatching. This greenish shank coloration, often designated as “willow,” may vary in incidence from 12 to 80% of the females at the broiler age.

Microstructures amplify carotenoid plumage signals in colorful tanagers [PDF]
, 2019 AbstractRed, orange, and yellow carotenoid-colored plumages have been considered honest signals of condition. We comprehensively quantified carotenoid signals in the social, sexually-dimorphic tanager genusRamphocelususing scanning electron microscopy (SEM), finite-difference time-domain (FDTD) optical modeling, liquid chromatography–mass spectrometry (
