SUMMARY Iridescence is produced by coherent scattering of light waves from alternating layers of materials of different refractive indices. In birds, iridescent colours are produced by feather barbules when light is scattered from alternating layers of keratin, melanin and air. The structure and organization of these layers, and hence the appearance of bird species with different types of plumage iridescence, varies extensively. One principal distinction between different types of iridescent… 

Iridescent structural colour production in male blue-black grassquit feather barbules: the role of keratin and melanin

These models indicate that both the keratin and the melanin layers are essential for production of the observed colour, influencing the coherent scattering of light, and stress the importance of considering natural variation when characterizing such photonic structures.

Evolutionary transitions and mechanisms of matte and iridescent plumage coloration in grackles and allies (Icteridae)

Optical models imply that rearrangement of melanin granules in barbules is a mechanism for shifts between black and iridescent colours, and that the relative simplicity of this mechanism may explain the lability of plumage colour state within this group.

Evolution of brilliant iridescent feather nanostructures

The evolution of thin melanin layers unlocks color-producing possibilities, more than doubling the range of colors that can be produced with a thick melanin layer and simultaneously increasing brightness.

Nanostructural self-assembly of iridescent feather barbules through depletion attraction of melanosomes during keratinization

Light and electron microscopy is used to compare the ontogeny of iridescent male and non-iridescent female feathers in blue-black grassquits and finds that nanostructural organization of male barbules occurs late in development, following death of the barbule cell, and is thus unlikely to be under direct cellular control, contrary to previous suggestions.

Mechanisms of evolutionary change in structural plumage coloration among bluebirds (Sialia spp.)

The morphology of blue rump barbs is similar among the three species, with an outer keratin cortex layer surrounding a medullary ‘spongy layer’ and a basal row of melanin granules, while in rusty barbs, melanin is present only in the cortex.

Decreased hydrophobicity of iridescent feathers: a potential cost of shiny plumage

Using light microscopy, spectrometry, contact angle goniometry and self-cleaning experiments, it is shown that iridescent feathers of mallards, Anas platyrhynchos, are less hydrophobic than adjacent non-iridescence feathers, and that this is primarily caused by differences in barbule microstructure.

Achieving luster: prenuptial molt pattern predicts iridescent structural coloration in Blue-black Grassquits

Colors in feathers are produced by pigment deposition or by nanostructures within barbs or barbules. In the absence of pigments or nanostructures, light is scattered incoherently, producing white

Proximate bases of silver color in anhinga (Anhinga anhinga) feathers

Colors of living organisms are produced by selective light absorption from pigments and/or by light scattering from highly ordered nanostructures (i.e., structural color). While the physical bases of

Plumage iridescence is associated with distinct feather microbiota in a tropical passerine

This study is the first to point to structural plumage coloration as a factor that may significantly regulate feather microbiota, and suggests that distinctive nanostructure properties of iridescent male feathers or different investment in preening influence feather microbiota community composition and load.



Structural colours from the feathers of the bird Bostrychia hagedash

Iridescence in the bird Bostrychia hagedash is interesting in the sense that instead of the usual single, fairly narrow, reflection peak seen for many birds and insects, up to six strong peaks were

Plumage Reflectance and the Objective Assessment of Avian Sexual Dichromatism

This study revealed previously unnoticed sex differences in plumage coloration and the nature of iridescent and noniridescent sex differences, which has important implications for classifications of animals as mono‐ or dimorphic and for taxonomic and conservation purposes.

Spectral reflectance and directional properties of structural coloration in bird plumage.

To study the optical and visual properties of structural plumage colours, the reflectance spectra of feathers were recorded and in particular their directional properties were recorded.

Nanostructure predicts intraspecific variation in ultraviolet–blue plumage colour†

Observations show that the precision of nanostructural arrangement determines some colour variation in feathers, particularly within the spongy layer of feather barbs.

Multiple sexual ornaments in satin bowerbirds: ultraviolet plumage and bowers signal different aspects of male quality

The findings support the multiple messages hypothesis of multicomponent signals: Female satin bowerbirds should assess both male and bower features to choose the highest quality mates.

Iridescent Colors of Hummingbird Feathers

The reflectance spectra of iridescent hummingbird feathers were measured spectrophotometrically for many species, and the structure of the iridescent parts of such feathers investigated by electron

Concordant evolution of plumage colour, feather microstructure and a melanocortin receptor gene between mainland and island populations of a fairy–wren

With the possible involvement of a melanocortin receptor locus, increased melanin density may mask the blue–producing microstructure in black island males, resulting in the divergence of plumage coloration between mainland and island white–winged fairy–wrens.


The results support recent findings that structural plumage coloration is condition-dependent, and this type of coloration may be an honest signal of male quality in the Blue-black Grassquit.


Two-dimensional Fourier analysis of transmission electron micrographs of the medullary keratin of UV-colored feather barbs of the Blue Whistling Thrush demonstrates that the Myiophonus medullaries keratin is ordered at the appropriately nanoscale to produce the observed UV hues by coherent scattering.

Carotenoids need structural colours to shine

It is shown that some yellow plumage colour is created both by reflection of light from white structural tissue and absorption of light by carotenoids, so that structural components of feathers contribute substantially to yellow ‘carotenoid’ displays.
