Dietary Carotenoid Supplementation Affects Orange Beak but not Foot Coloration in Gentoo Penguins Pygoscelis papua
International audience Red, orange, and yellow carotenoid-based coloration abounds in birds, with over half of all avian orders known to display it in some form. Penguins (Order Sphenisciformes), however, are one order of birds for which the proximal causation of ornaments is unclear, i.e., whether...
