Medical Causes of Feather Damaging Behavior

Area of Science:

• Avian Medicine
• Veterinary Dermatology
• Animal Behavior

Background:

• Feather damaging behavior (FDB), including feather picking and plucking, is a prevalent and challenging issue in captive parrots (psittacines).
• Identifying the root causes of FDB is crucial for effective treatment and improving the welfare of these birds.
• Medical conditions, ranging from primary skin and feather diseases to systemic illnesses, can precipitate FDB.

Purpose of the Study:

• To review the clinical approach for identifying underlying medical conditions associated with feather damaging behavior in captive psittacines.
• To focus on the medical etiologies of FDB as documented in current avian literature.
• To discuss the key components of a multifaceted therapeutic strategy for managing medically-induced FDB.

Main Methods:

• A comprehensive review of the current scientific literature on feather damaging behavior in psittacines.
• Application of the VITAMIN D diagnostic algorithm to categorize and present potential medical causes of FDB.
• Discussion of therapeutic principles for managing FDB originating from medical conditions.

Main Results:

• Feather damaging behavior in parrots can stem from various primary or systemic medical conditions.
• The VITAMIN D algorithm provides a structured framework for investigating the medical differential diagnoses of FDB.
• Effective management requires addressing the underlying medical cause and implementing a comprehensive treatment plan.

Conclusions:

• Medical conditions are significant contributors to feather damaging behavior in captive parrots.
• A systematic diagnostic approach, such as the VITAMIN D algorithm, is essential for identifying these medical causes.
• Multifaceted therapeutic strategies targeting the underlying medical issues are key to successfully managing FDB.
