Melanism (dark coloration) is a condition resulting from a greater than normal expression of the eumelanin pigments in the plumage (Gill 1990). The dark coloration can be advantageous to raptors by increasing the feathers’ resistance to bacterial degradation (Goldstein et al. 2004). conversely, abnormally dark pigmentation can reduce success in pairing by disguising key species-identification cues (Garcia 2003) and decrease lifetime reproductive success by increasing mortality (kruger and…

Are simple plumage traits sufficient for species discrimination by harrier males
TLDR
Evidence is provided that the Montagu's harrier Circus pygargus and the hen harrier C. cyaneus are able to recognise plumage features of their own and the sibling species.
Lifetime reproductive success in common buzzard, Buteo buteo: from individual variation to population demography
TLDR
Most phenomena on all levels from individual breeding attempts over lifetime reproductive success to population demography can be explained by the fitness differences between the colour morphs with the intermediate morph maintaining the current population renewal potential.
Colour polymorphism in birds: causes and functions
TLDR
Findings support the hypothesis that colour polymorphism probably evolved under selective pressures linked to bird detectability as affected by variable light conditions during activity period as well as selective agents may be prey, predators and competitors.
Conserved Genetic Basis of a Quantitative Plumage Trait Involved in Mate Choice
TLDR
Phylogenetic reconstructions of variant MC1R alleles in geese and skuas show that melanism is a derived trait that evolved in the Pleistocene.
Convergence in pigmentation at multiple levels: mutations, genes and function
TLDR
This work shows that different genes can be responsible for convergent phenotypes even among closely related populations, for example, in the pale beach mice inhabiting Florida's Gulf and Atlantic coasts and shows how convergence can occur at different genetic levels.
