Does feather corticosterone reflect individual quality or external stress in arctic-nesting migratory birds? [PDF]
PLoS ONE, 2013 The effects of environmental perturbations or stressors on individual states can be carried over to subsequent life stages and ultimately affect survival and reproduction. The concentration of corticosterone (CORT) in feathers is an integrated measure of

Assessing costs of carrying geolocators using feather corticosterone in two species of aerial insectivore [PDF]
Royal Society Open Science, 2015 Despite benefits of using light-sensitive geolocators to track animal movements and describe patterns of migratory connectivity, concerns have been raised about negative effects of these devices, particularly in small species of aerial insectivore ...

Research Note: Quantifying corticosterone in turkey (Meleagris gallopavo) feathers using ELISA
Poultry Science, 2020 The measurement of corticosterone in feathers is an appealing tool for assessing glucocorticoids in wild and domestic bird species. Feather corticosterone measurements can be performed noninvasively and can provide a means for comparing glucocorticoid ...

Validation of an Alternative Feather Sampling Method to Measure Corticosterone [PDF]
Animals, 2020 The most common feather sampling method for feather corticosterone measurement is by plucking the feathers from the bird’s skin. This procedure performed on living, restrained birds is qualified as an animal experiment according to German/European ...

Effects of feather processing methods on quantity of extracted corticosterone in broiler chickens
Journal of Animal Science and Technology, 2020 Corticosterone is known as a biological stress index in many species including birds. Feather corticosterone concentration (FCC) has increasingly been used as a measure for chronic stress status in broiler chickens.

Effects of Small Increases in Corticosterone Levels on Morphology, Immune Function, and Feather Development [PDF]
Physiological and Biochemical Zoology, 2010 Stressors encountered during avian development may affect an individual’s phenotype, including immunocompetence, growth, and feather quality. We examined effects of simulated chronic low-level stress on American kestrel (Falco sparverius) nestlings ...
