Production of plumage ornaments among males and females of two closely related tropical passerine bird species

DOI: 10.1002/ece3.3000
Abstract: Abstract The evolution of elaborate secondary sexual traits (i.e., ornaments) is well‐studied in males but less so in females. Similarity in the appearance of ornaments between males and females supports the view that female ornaments… read more here.

White eye patches of female wood ducks, Aix sponsa, vary markedly in size and may reflect individual status or condition

DOI: 10.1016/j.anbehav.2020.06.023
Abstract: Research into plumage ornaments and plumage signals of individual state has focused primarily on males, while variation among females has received far less attention. White patches of plumage around the eye (eye patches) are a… read more here.

Pigeons in the sun: Thermal constraints of eumelanic plumage in the rock pigeon (Columba livia).

DOI: 10.1016/j.jtherbio.2020.102601
Abstract: In wild vertebrates, several species exhibit eumelanic color polymorphism with the coexistence of dark and light morphs. The maintenance of such polymorphism suggests the existence of a selective balance between the morphs and a large… read more here.

DOI: 10.1016/j.ygcen.2018.10.015
Abstract: The production of high quality secondary sexual traits can be constrained by trade-offs in the allocation of energy and nutrients with other metabolic activities, and is mediated by physiological processes. In birds, the factors influencing… read more here.

DOI: 10.1038/s41467-021-21340-y
Abstract: Genome-wide variation in introgression rates across hybrid zones offers a powerful opportunity for studying population differentiation. One poorly understood pattern of introgression is the geographic displacement of a trait implicated in lineage divergence from genome-wide… read more here.

DOI: 10.1080/1828051x.2017.1413598
Abstract: Abstract Padovana female chickens of two plumage varieties, chamois (PC) and silver (PS) and their cross (PC male × PS female) were reared from 1 d until 200 d of age, when they were slaughtered. PC has… read more here.

Female and male plumage color is linked to parental quality, pairing, and extrapair mating in a tropical passerine

DOI: 10.1093/beheco/araa154
Abstract: Sexual selection has been proposed to drive the evolution of elaborate phenotypic traits in males, which often confer success in competition or mating. However, in many species, both males and females display such traits. Studies… read more here.

Plumage brightness and uropygial gland secretions in barn swallows
Sign Up to like & getrecommendations! Published in 2019 at "Current Zoology"
DOI: 10.1093/cz/zoy042
Abstract: Abstract The uropygial gland has been hypothesized to play a role in sexual signaling through a “make-up” function derived from the effects of secretions from the gland on the appearance of the plumage and bare… read more here.

DOI: 10.1098/rsif.2022.0920
Abstract: Until recently, and when compared with diurnal birds that use contrasting plumage patches and complex feather structures to convey visual information, communication in nocturnal species was considered to follow acoustic and chemical channels. However, many… read more here.

When to measure plumage reflectance: a lesson from Collared Flycatchers Ficedula albicollis

DOI: 10.1111/ibi.12609
Abstract: Sexually selected colour traits of bird plumage are widely studied. Although the plumage is replaced only at one or two yearly moults, plumage colour has long been shown to change between moults. Nevertheless, most studies… read more here.

Males in seemingly female-like plumage do not mimic females: UV reflectance reveals temporal cryptic dimorphism in a manakin species exhibiting delayed plumage maturation

DOI: 10.1111/jav.01467
Abstract: Manakins (Pipridae) are neotropical birds that usually exhibit delayed plumage maturation (DPM). Thus, while plumage of most adult male manakins is brightly conspicuous, subadult males and females are basically dull-olive green. Although sexual dichromatism in… read more here.
