Feather corticosterone levels on wintering grounds have no carry-over effects on breeding among three populations of great skuas (Stercorarius skua) [PDF]
, 2014 Environmental conditions encountered by migratory seabirds in their wintering areas can shape their fitness. However, the underlying physiological mechanisms remain largely unknown as birds are relatively inaccessible during winter.

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

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

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 ...

Across-Line SNP Association Study for Direct and Associative Effects on Feather Damage in Laying Hens [PDF]
, 2010 An association study between SNP markers and feather condition score on the back, rump and belly of laying hens was performed. Feather condition score is a measure of feather damage, which has been shown to be closely related to feather pecking behaviour

Early feather pecking as a form of social exploration:the effect of group stability on feather pecking and tonic immobility in domestic chicks [PDF]
, 2002 In two lines of White Leghorns that differ in their propensity to feather peck, feather pecking was already present I day after hatching. A significant line difference developed within 3 days and this difference remained in the following weeks. There was

Exposing image forgery by detecting traces of feather operation [PDF]
, 2015 Powerful digital image editing tools make it very easy to produce a perfect image forgery. The feather operation is necessary when tampering an image by copy–paste operation because it can help the boundary of pasted object to blend smoothly and ...

First record of feather-loss disorder in Antarctic penguins [PDF]
, 2014 Little is known about diseases affecting Antarctic wildlife (Kerry & Riddle 2009). Understanding the patterns, causes and effects of disease in these populations is crucial as many of these species are already threatened by rapid environmental changes ...
