Vibrational spectroscopic analyses of unique yellow feather pigments (spheniscins) in penguins.
Many animals extract, synthesize and refine chemicals for colour display, where a range of compounds and structures can produce a diverse colour palette. Feather colours, for example, span the visible spectrum and mostly result from pigments in five chemical classes (carotenoids, melanins, porphyrins, psittacofulvins and metal oxides). However, the pigment that generates the yellow colour of pe...
متن کاملAnnual, sexual, size- and condition-related variation in the colour and fluorescent pigment content of yellow crest-feathers in Snares Penguins (Eudyptes robustus)
Colourful plumages observed in many birds provide ideal systems for investigating the control and function of animal signals, because we can identify the molecular currency (e.g. pigments, tissue structures) and thus the challenges associated with the production of the trait. To date, most attention has been paid to the signalling costs and benefits of the common pigmentary (e.g. carotenoidandm...
متن کاملDistribution of unique red feather pigments in parrots.
In many birds, red, orange and yellow feathers are coloured by carotenoid pigments, but parrots are an exception. For over a century, biochemists have known that parrots use an unusual set of pigments to produce their rainbow of plumage colours, but their biochemical identity has remained elusive until recently. Here, we use high-performance liquid chromatography to survey the pigments present ...
متن کاملRed-winged blackbirds Agelaius phoeniceus use carotenoid and melanin pigments to color their epaulets
Over the past three decades, the red-winged blackbird Agelaius phoeniceus has served as a model species for studies of sexual selection and the evolution of ornamental traits. Particular attention has been paid to the role of the colorful red-and-yellow epaulets that are striking in males but reduced in females and juveniles. It has been assumed that carotenoid pigments bestow the brilliant red...
متن کاملSpectral tuning of Amazon parrot feather coloration by psittacofulvin pigments and spongy structures.
The feathers of Amazon parrots are brightly coloured. They contain a unique class of pigments, the psittacofulvins, deposited in both barbs and barbules, causing yellow or red coloured feathers. In specific feather areas, spongy nanostructured barb cells exist, reflecting either in the blue or blue-green wavelength range. The blue-green spongy structures are partly enveloped by a blue-absorbing...
