Does feather corticosterone reflect individual quality or external stress in arctic-nesting migratory birds?
International audience 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 hypothalamic-pituitary...

International audience The effects of environmental perturbations or stressors on individual states can be carried over to subsequent life stages and ultimately affect survival and reproduction.

Common eiders and greater snow geese replace all flight feathers once a year during the pre-basic molt, which occurs following breeding.
