Sexually and socially selected signals are predicated to express the present and past
condition of individuals and thereby their capacity to cope with environmental challenges.
The concentration of corticosterone in feathers (CORTf) has been validated as a marker of
activation of the hypothalamic-pituitary axis in birds during feather development.
Measurements of CORTf can thus express the physiological stress of migratory birds during
non-breeding periods of the annual cycle when feathers moulted in the wintering range are …
