Stable immune function during moult regardless of age-specific moulting strategy in a European passerine
Moult, the regular replacement of feathers, is a resource-intense avian annual-cycle stage. Resource allocation to support feather regrowth may require downregulation of other physiological processes, such as immune function, which is critical for preventing disease-related mortality. At the same time, the emergence of new feathers may increase the risk of skin injury and infection, potentially re
