Sexually selected male plumage color is testosterone dependent in a tropical passerine bird, the red-backed fairy-wren (Malurus melanocephalus). [PDF]
BACKGROUND: Sexual signals, such as bright plumage coloration in passerine birds, reflect individual quality, and testosterone (T) may play a critical role in maintaining signal honesty.

Assessment of the Expression of Phenotypic Traits in Male and Female Indigenous Chickens (Gallus gallus domesticus L.) in Rajshahi, Bangladesh [PDF]
This study aimed to identify and describe phenotypic traits of indigenous chicken (Gallus gallus domesticus L.) populations in five market sites in Rajshahi City, Bangladesh: Shaheb Bazar (S1), Court Bazar (S2), Vodra Bazar (S3), Binodpur Bazar (S4), and

Social environment affects acquisition and color of structural nuptial plumage in a sexually dimorphic tropical passerine. [PDF]
Structural colors result from the physical interaction of light with organic materials of differing refractive indexes organized at nanoscale dimensions to produce significant interference effects.

Investigation of MC1R SNPs and Their Relationships with Plumage Colors in Korean Native Chicken [PDF]
The melanocortin 1 receptor (MC1R) gene is related to the plumage color variations in chicken. Initially, the MC1R gene from 30 individuals was sequenced and nine polymorphisms were obtained. Of these, three and six single nucleotide polymorphisms (SNPs)

Ultraviolet plumage colors predict mate preferences in starlings [PDF]
Avian plumage has long been used to test theories of sexual selection, with humans assessing the colors. However, many birds see in the ultraviolet (<400 nm), to which humans are blind. Consequently, it is important to know whether natural variation in UV reflectance from plumage functions in sexual signaling.
