Feather function and the evolution of birds
Biological Reviews of The Cambridge Philosophical Society, 2022 The ability of feathers to perform many functions either simultaneously or at different times throughout the year or life of a bird is integral to the evolutionary history of birds.

The feather degradation mechanisms of a new Streptomyces sp. isolate SCUT-3
Communications Biology, 2020 Feather waste is the highest protein-containing resource in nature and is poorly reused. Bioconversion is widely accepted as a low-cost and environmentally benign process, but limited by the availability of safe and highly efficient feather degrading ...

Feather versus non-feather bedding for asthma [PDF]
Cochrane Database of Systematic Reviews, 2000 Two recent epidemiological studies have reported that children using non-feather pillows suffered from more frequent episodes of wheeze than those using feather pillowsTo evaluate the efficacy of using feather bedding in the control of asthma symptoms.The Cochrane Airways Group asthma clinical trials register, derived from MEDLINE, EMBASE and hand ...

The Airlines’ Recent Experience Under the Railway Labor Act [PDF]
, 1960 Silky-feather has been selected and fixed in some breeds due to its unique appearance. This phenotype is caused by a single recessive gene (hookless, h). Here we map the silky-feather locus to chromosome 3 by linkage analysis and subsequently fine-map it

Feather growth rate and mass in nearctic passerines with variablemigratory behavior and molt pattern [PDF]
, 2012 Bird species vary greatly in the duration of their annual complete feather molt. However, such variation is not well documented in birds from many biogeographic areas, which restricts our understanding of the diversification of molt strategies.

Progress in Microbial Degradation of Feather Waste
Frontiers in Microbiology, 2019 Feathers are a major by-product of the poultry industry. They are mainly composed of keratins which have wide applications in different fields. Due to the increasing production of feathers from poultry industries, the untreated feathers could become ...

Images and Models of Thought [PDF]
, 2017 One really extraordinary ability of the mind is its capacity to match objects and form plausible hypotheses from just a few elements that we see through our eyes. We recognize a feather even if it is mostly covered by a book sitting on top of it. Even if

Feather arrays are patterned by interacting signalling and cell density waves
PLoS Biology, 2019 Feathers are arranged in a precise pattern in avian skin. They first arise during development in a row along the dorsal midline, with rows of new feather buds added sequentially in a spreading wave.

Carotenoid metabolism strengthens the link between feather coloration and individual quality
Nature Communications, 2018 Thirty years of research has made carotenoid coloration a textbook example of an honest signal of individual quality, but tests of this idea are surprisingly inconsistent.

Water bathing alters threat perception in starlings. [PDF]
, 2012 The majority of bird taxa perform water bathing, but little is known about the adaptive value of this behaviour. If bathing is important for feather maintenance then birds that have not bathed should have poorer feather condition, compromised escape ...
