Birds' feathers also go grey with the age
A study from the Ecological Pyrenean Institute (IPE-CSIC) and the Doñana Biological Station shows that some birds’ feathers turn white with the age.
? The study was carried out in natural...

Impairment of mixed melanin-based pigmentation in parrots
Parrots and allies (Order Psittaciformes) have evolved an exclusive capacity to synthesize polyene pigments called psittacofulvins at feather follicles, which allows them to produce a striking...

A source of exogenous oxidative stress improves oxidative status and favors pheomelanin synthesis in zebra finches
Some organisms can modulate gene expression to trigger physiological responses that help adapt to environmental stress. The synthesis of the pigment pheomelanin in melanocytes seems to be one of...

Juvenile pheomelanin-based plumage colouration has evolved more frequently in carnivorous species
Distinctive pheomelanin-based plumage colouration in juvenile birds has been proposed as a signal of immaturity to avoid aggression by older conspecifics, but recent findings suggest a detoxifying...

A negative association between melanin-based plumage color heterogeneity and intensity in birds
Even though plumage diversity is one of the most diverse phenotypic traits in nature, the reasons why some species exhibit more distinctive colors than others are poorly known. In the case of...
