Plumage color degradation indicates reproductive effort: an experiment. [PDF]
Sci Rep, 2023 AbstractPlumage color has traditionally been regarded as a static ornamental trait, but evidence is accumulating for significant color changes without molt that typically reduce the conspicuousness of ornamentation. In some species, the social partner seems to increase its reproductive investment if the color trait is experimentally enhanced ...

Association between Synonymous SNPs of SOX10 and Plumage Color and Reproductive Traits of Ducks [PDF]
Animals, 2022 Mutations in the SOX10 gene affect the plumage color of chickens and pigeons. The mutation also causes abnormal pigmentation of the skin and hair color, as well as postnatal growth retardation and reproduction problems in humans and mice.

Environmental and social correlates of the plumage color polymorphism in an urban dweller, feral pigeon (Columba livia f. domestica) [PDF]
Scientific ReportsWe examined how urban environments affect the abundance, proportion, and diversity of plumage color morphs in feral pigeons. Five major plumage color morphs (black, blue, white, red, and mixed) were counted in sixty 25-ha plots in Poznań City (Poland ...
