Colorful feathers such as those belonging to pheasants have been used to decorate fishing lures. 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. [52]
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...

Plumage (from Latin pluma 'feather') is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes.
If the green pigment in Jacana is truly turacoverdin, then the pigment must have evolved independently in this order. This is further supported by the fact that the pigment in Jacana is located only in the remiges, while in all musophagid and galliform species, the pigment is found mainly in body feathers. [6]
A few years ago, Maria McNamara was invited to Brussels by fellow paleontologist Pascal Godefroit and presented with an intriguing opportunity.
The tail feathers are used to control flight acting as rudder and brake, only some of these feathers are as firmly attached as the bird's primaries. Contour feathers are arranged on the body of the bird in the manner of roof tiles. The tips of these feathers are waterproof and help protect the bird from the elements, while the inner parts of ...
