Growing new feathers is quite stressful on your birds body. Feather growth requires massive amounts of nutrition, especially proteins, amino acids and calcium. Low levels of Vitamin A also result in skin and feather problems. Feather stress bars are caused when a a bird experiences stressors and / or vitamin deficiency while a new feather is growing.
While it is common to see stress bars in chicks or baby birds, stress bars in adult parrots should be taken seriously. If you notice stress bars on feathers, carefully think back about what stressful event may have occurred. If you are unable to remember a stressful event, the culprit may be an inadequate diet. More often than not, inadequate diet is responsible.
Numerous stress bars and general poor feather condition may warrant a trip to the avian vet. Your vet will want to assess wither the stress bars are related to poor nutrition or illness and help you address the cause before it becomes a chronic or serious problem.
Avian vets are specialist in bird care and they can properly advise you on bird nutrition and creating the optimum environment to help your parrot thrive.
