Die Lipochromf~orbung der Vogelfedern ist im allgemeinen sehe widerstandsf:Shig; ihr Verblassen ist sogar an alten B~ilgen kaum zu merken. Eine Ausnahme bildet cfie rosenrote TSnu~_g, welche wir an ,den weiBen Federn des Pelikans, der RosenmSwe und verschiedener anderer VSget so sehr bewurrdern. Bei langem Liegen in Sammlungen verblaBt diese F/irbung stark, in manchen F/illen bis zum v511igen Versehwinden. Je stKrker die F/irbung entwickelt ist, desto l~nger hKlt sie vor. Bei alten RosenmSwen… 
Über die Rosafärbung bei Schneehühnern
Diese Erscheinung ist mittlerweile bei allen Schneehfihnern, also auch bei Alpenschneehuhn (L. mutus) und Weifschwanzschneehuhn (L. leucurus) in Alaska beobachtet worden (IRVING 1960). IRVING
Greater flamingos Phoenicopterus roseus use uropygial secretions as make-up
It is shown not only that the colour of feathers of greater flamingos Phoenicopterus roseus became more colourful due to the application of carotenoids from uropygial secretions over the plumage but also that the feathers became more colours with the quantity of pigments applied over them, thus providing evidence of cosmetic coloration.
Astaxanthin is responsible for the pink plumage flush in Franklin's and Ring-billed gulls
It is hypothesized that some gulls turn pink because they acquire unusually high amounts of astaxanthin in their diets at the time of feather growth, and the increase in sightings of pink Ring- billed Gulls since the late 1990s with the introduction of pure, synthetic astaxantina to the diets of hatchery-raised salmon.
The Pink Feather Blush of the Roseate Tern
A pink blush apparently characterizes the plumage of the Roseate Tern for most of the year, often being more prominent in January/February during the non-breeding season than in breeding birds in May.

Cosmetic Coloration in Birds: Occurrence, Function, and Evolution
It is argued that the need for preserving plumage condition and hence signaling content might have given rise to a novel type of sexual signal: cosmetic coloration, which is more widespread than currently realized and occurring in at least 13 bird families.
