Association of Tyrosinase (TYR) and Tyrosinase-related Protein 1 (TYRP1) with Melanic Plumage Color in Korean Quails () [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2013
TYR (Tyrosinase) and TYRP1 (Tyrosinase-related protein 1) play crucial roles in determining the coat color of birds. In this paper, we aimed to characterize the relationship of TYR and TYRP1 genes with plumage colors in Korean quails.

Plumage Color Patterns of an Extinct Dinosaur [PDF]

open access: yesScience, 2010
Dinosaur Plumage Coloration and appearance provide important behavioral and evolutionary information in animals. However, for the most part, we do not know the coloration of fossil terrestrial animals. Li et al.

Extreme offspring ornamentation in American coots is favored by selection within families, not benefits to conspecific brood parasites [PDF]

open access: yes, 2019
Offspring ornamentation typically occurs in taxa with parental care, suggesting that selection arising from social interactions between parents and offspring may underlie signal evolution.

Sexual dichromatism and assortative mating by multiple plumage color traits in wild Chestnut Thrush

open access: yesAvian Research, 2022
Sex differences in plumage color are common in bird species. Some bird species are regarded as sexually monochromatic in human visual systems, and in recent years, some species are found to be of cryptic (to human) sexual dichromatism by ...

The Growth Pattern of Brazilian Canela-Preta Chickens with Different Plumages Reared in Two Rearing Systems [PDF]

open access: yesBrazilian Journal of Poultry Science, 2023
Growth pattern is essential for economically efficient poultry production. In this study, we aimed to describe the growth curve of chickens of the Canela-Preta breed reared in two different rearing systems, considering their different plumage colors ...

The Genetics of Seasonal Migration and Plumage Color [PDF]

open access: yesCurrent Biology, 2016
Details on the genetics of behavioral and quantitative phenotypes remain limited to a few organisms. Such information is central to understanding both adaptation and speciation, as many of these phenotypes reduce gene flow between taxa [1-3]. Hybrid zones provide an ideal arena for studying this topic, as they consist of recombinant genotypes that ...

Selection and Crossbreeding in Relation to Plumage Color Inheritance in Three Chinese Egg Type Duck Breeds () [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2014
In China and South East Asia, the duck (common duck) is important in egg production for human consumption. Plumage color is a breed characteristic and of economic importance, together with egg production.

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

open access: yes, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.

Integration of spectral reflectance across the plumage: implications for mating patterns. [PDF]

open access: yesPLoS ONE, 2011
In complex sexual signaling systems such as plumage color, developmental or genetic links may occur among seemingly distinct traits. However, the interrelations of such traits and the functional significance of their integration rarely have been examined.

Methods for correcting plumage color fading in the Barn Swallow [PDF]

open access: yes, 2008
It is necessary to correct plumage color fading when comparing the plumage coloration of birds captured at different times during the breeding season. We proposed two methods for correcting plumage color fading and compared them using the throat feathers
