In contrast to the conventional work of museums, Featherbase is much more oriented towards the general public, allowing not just enrolled scientists the opportunity to gain access to the collection, but anyone with an interest in studying birds and their feathers.
Featherbase also frequently collaborates with scientific or educational organizations by offering images, data or teamwork in general.
Featherbase works completely independently, without administrative affiliation, and first and foremost without commercial interests.
We are a non-profit making entity and funded entirely by our own contributors. Featherbase Since the 20th century, scientific ornithology has been closely linked to the conservation of birds.
Merops albicollis White-throated bee-eater. Amazona arausiaca Red-necked Parrot. Calyptorhynchus funereus Yellow-tailed Black-Cockatoo.
Amazona guildingii St. Vincent Parrot. Turdus eunomus Naumann's Thrush. Grebes are peculiar in their habit of ingesting their own feathers and feeding them to their young.
Observations on their diet of fish and the frequency of feather eating suggest that ingesting feathers, particularly down from their flanks, aids in forming easily ejectable pellets.
Contour feathers are not uniformly distributed on the skin of the bird except in some groups such as the penguins , ratites and screamers. Filoplumes and down may arise from the apterylae.
The arrangement of these feather tracts, pterylosis or pterylography, varies across bird families and has been used in the past as a means for determining the evolutionary relationships of bird families.
The colors of feathers are produced by pigments, by microscopic structures that can refract , reflect, or scatter selected wavelengths of light, or by a combination of both.
Most feather pigments are melanins brown and beige pheomelanins , black and grey eumelanins and carotenoids red, yellow, orange ; other pigments occur only in certain taxa — the yellow to red psittacofulvins  found in some parrots and the red turacin and green turacoverdin porphyrin pigments found only in turacos.
Structural coloration    is involved in the production of blue colors, iridescence , most ultraviolet reflectance and in the enhancement of pigmentary colors.
Structural iridescence has been reported  in fossil feathers dating back 40 million years. White feathers lack pigment and scatter light diffusely; albinism in birds is caused by defective pigment production, though structural coloration will not be affected as can be seen, for example, in blue-and-white budgerigars.
The blues and bright greens of many parrots are produced by constructive interference of light reflecting from different layers of structures in feathers.
In the case of green plumage, in addition to yellow, the specific feather structure involved is called by some the Dyck texture. In some birds, feather colors may be created, or altered, by secretions from the uropygial gland , also called the preen gland.
The yellow bill colors of many hornbills are produced by such secretions. It has been suggested that there are other color differences that may be visible only in the ultraviolet region,  but studies have failed to find evidence.
The reds, orange and yellow colors of many feathers are caused by various carotenoids. A bird's feathers undergo wear and tear and are replaced periodically during the bird's life through molting.
New feathers, known when developing as blood, or pin feathers , depending on the stage of growth, are formed through the same follicles from which the old ones were fledged.
The presence of melanin in feathers increases their resistance to abrasion. They observed that the greater resistance of the darker birds confirmed Gloger's rule.
Although sexual selection plays a major role in the development of feathers, in particular the color of the feathers it is not the only conclusion available.
New studies are suggesting that the unique feathers of birds is also a large influence on many important aspects of avian behavior, such as the height at which a different species build their nests.
Since females are the prime care givers, evolution has helped select females to display duller colored down so that they may blend into the nesting environment.
The position of the nest and whether it has a greater chance of being under predation has exerted constraints on female birds' plumage.
Since the female is the main care giver in some species of birds, evolution has helped select traits that make her feathers dull and often allow her to blend into the surroundings.
The height study found that birds that nest in the canopies of trees often have many more predator attacks due to the brighter color of feathers that the female displays.
Birds develop their bright colors from living around certain colors. Most bird species often blend into their environment, due to some degree of camouflage, so if the species habitat is full of colors and patterns, the species would eventually evolve to blend in to avoid being eaten.
Birds' feathers show a large range of colors, even exceeding the variety of many plants, leaf and flower colors. The feather surface is the home for some ectoparasites, notably feather lice Phthiraptera and feather mites.
Feather lice typically live on a single host and can move only from parents to chicks, between mating birds, and, occasionally, by phoresy.
This life history has resulted in most of the parasite species being specific to the host and coevolving with the host, making them of interest in phylogenetic studies.
Feather holes are chewing traces of lice most probably Brueelia spp. They were described on barn swallows , and because of easy countability, many evolutionary, ecological, and behavioral publications use them to quantify the intensity of infestation.
Parasitic cuckoos which grow up in the nests of other species also have host-specific feather lice and these seem to be transmitted only after the young cuckoos leave the host nest.
Birds maintain their feather condition by preening and bathing in water or dust. It has been suggested that a peculiar behavior of birds, anting , in which ants are introduced into the plumage, helps to reduce parasites, but no supporting evidence has been found.
Feathers are both soft and excellent at trapping heat ; thus, they are sometimes used in high-class bedding , especially pillows , blankets , and mattresses.
They are also used as filling for winter clothing and outdoor bedding, such as quilted coats and sleeping bags. Goose and eider down have great loft , the ability to expand from a compressed, stored state to trap large amounts of compartmentalized, insulating air.
Bird feathers have long been used for fletching arrows. Colorful feathers such as those belonging to pheasants have been used to decorate fishing lures.
Feathers of large birds most often geese have been and are used to make quill pens. The word pen itself is derived from the Latin penna , meaning feather.
Feathers are also valuable in aiding the identification of species in forensic studies, particularly in bird strikes to aircraft.
The ratios of hydrogen isotopes in feathers help in determining the geographic origins of birds. The poultry industry produces a large amount of feathers as waste, which, like other forms of keratin, are slow to decompose.
Feather waste has been used in a number of industrial applications as a medium for culturing microbes,  biodegradeable polymers,  and production of enzymes.
Some groups of Native people in Alaska have used ptarmigan feathers as temper non-plastic additives in pottery manufacture since the first millennium BC in order to promote thermal shock resistance and strength.
Historically, the hunting of birds for decorative and ornamental feathers including in Victorian fashion has endangered some species and helped to contribute to the extinction of others.
Eagle feathers have great cultural and spiritual value to American Indians in the US and First Nations peoples in Canada as religious objects.
In the United States the religious use of eagle and hawk feathers is governed by the eagle feather law , a federal law limiting the possession of eagle feathers to certified and enrolled members of federally recognized Native American tribes.
In South America, brews made from the feathers of condors are used in traditional medications. Members of Scotland's Clan Campbell are known to wear feathers on their bonnets to signify authority within the clan.
Clan chiefs wear three, chieftains wear two and an armiger wears one. Any member of the clan who does not meet the criteria is not authorized to wear feathers as part of traditional garb and doing so is considered presumptuous.
During the 18th, 19th, and early 20th centuries, there was a booming international trade in plumes for extravagant women's hats and other headgear.
Frank Chapman noted in that feathers of as many as 40 species of birds were used in about three-fourths of the ladies' hats that he observed in New York City.
Conservationists led a major campaign against the use of feathers in hats. This contributed to passage of the Lacey Act in , and to changes in fashion.
The ornamental feather market then largely collapsed. More recently, rooster plumage has become a popular trend as a hairstyle accessory, with feathers formerly used as fishing lures now being used to provide color and style to hair.
These feathers are dyed and manipulated to enhance their appearance, as poultry feathers are naturally often dull in appearance compared to the feathers of wild birds.
Feather products manufacturing in Europe has declined in the last 60 years, mainly due to competition from Asia. Feathers have adorned hats at many prestigious events such as weddings and Ladies Day at racecourses Royal Ascot.
The functional view on the evolution of feathers has traditionally focused on insulation, flight and display. Discoveries of non-flying Late Cretaceous feathered dinosaurs in China,  however, suggest that flight could not have been the original primary function as the feathers simply would not have been capable of providing any form of lift.
In one fossil specimen of the paravian Anchiornis huxleyi , the features are so well preserved that the melanosome pigment cells structure can be observed.
By comparing the shape of the fossil melanosomes to melanosomes from extant birds, the color and pattern of the feathers on Anchiornis could be determined.
This pattern is similar to the coloration of many extant bird species, which use plumage coloration for display and communication, including sexual selection and camouflage.
It is likely that non-avian dinosaur species utilized plumage patterns for similar functions as modern birds before the origin of flight.
In many cases, the physiological condition of the birds especially males is indicated by the quality of their feathers, and this is used by the females in mate choice.
This suggests that the pennibrachium was a secondary sex characteristic and likely had a sexual function. Feathers and scales are made up of two distinct forms of keratin , and it was long thought that each type of keratin was exclusive to each skin structure feathers and scales.
However, a study published in confirmed the presence of feather keratin in the early stages of development of American alligator scales.
This type of keratin, previously thought to be specific to feathers, is suppressed during embryological development of the alligator and so is not present in the scales of mature alligators.
The presence of this homologous keratin in both birds and crocodilians indicates that it was inherited from a common ancestor.
This may suggest that crocodilian scales, bird and dinosaur feathers, and pterosaur pycnofibres are all developmental expressions of the same primitive archosaur skin structures; suggesting that feathers and pycnofibers could be homologous.
Several non-avian dinosaurs had feathers on their limbs that would not have functioned for flight. Another theory posits that the original adaptive advantage of early feathers was their pigmentation or iridescence, contributing to sexual preference in mate selection.
The majority of dinosaurs known to have had feathers or protofeathers are theropods , however featherlike "filamentous integumentary structures" are also known from the ornithischian dinosaurs Tianyulong and Psittacosaurus.
However, it is believed that the stage-1 feathers see Evolutionary stages section below such as those seen in these two ornithischians likely functioned in display.
Since the s, dozens of feathered dinosaurs have been discovered in the clade Maniraptora , which includes the clade Avialae and the recent common ancestors of birds, Oviraptorosauria and Deinonychosauria.
In , the discovery of a feathered oviraptorosaurian, Caudipteryx zoui , challenged the notion of feathers as a structure exclusive to Avialae. Present on the forelimbs and tails, their integumentary structure has been accepted [ by whom?
