Feather Destructive Behavior
Também conhecido como: Feather Picking, Feather Chewing, Self-Mutilation, Feather Plucking
Em resumo
Feather destructive behavior is a challenging avian condition where birds damage their own plumage or skin due to medical or psychological issues, requiring a comprehensive veterinary workup.

TL;DR. A ave mastiga, arranca ou danifica as próprias penas por causas médicas ou de stress; exige estudo veterinário sistemático.
Perda de penas no corpo com cabeça intacta é o padrão clássico.
O que é?
Feather destructive behavior is a sign of medical or psychological distress, not a single disease. Normal preening escalates to chewing shafts, plucking, or skin self-mutilation. Intelligent social species (African greys, cockatoos, macaws) are at higher risk when enrichment is poor.
Causas e fatores de risco
Medical: local pain, skin infection, parasites, heavy metals (lead, zinc), viruses affecting feather growth. Behavioral: boredom, isolation, stress (moves, loss of mate, noise, predator seen at a window). Often mixed.
Sinais a vigilar
- Intact head feathers (cardinal)
- Chewing under wing, thighs, or breast (common)
- Unilateral pattern (occasional; may suggest local pain)
- Skin self-mutilation (emergency)

Canudos mastigados e pele exposta: destruição ativa, não muda normal.
Como os veterinários diagnosticam
History (diet, cage, toxins), pattern exam. CBC, radiographs, PBFD test, fecal/Giardia, follicle biopsy if needed, blood lead and zinc. Rule out medical causes before labeling pure behavior.
Opções de tratamento
Treat medical cause first. Enrichment: foraging, rotating toys, bathing/misting, 10-12 h dark sleep. If needed, doxepin or clomipramine under supervision with environment change.
Prognóstico
Excellent if medical cause resolves early. Guarded in chronic habit; follicles may be permanently damaged. Untreated self-mutilation: guarded to poor.
Prevenção
Ongoing enrichment, stable routine, quality formulated diet, annual avian exams, avoid aerosols, PTFE fumes, and heavy-metal toys.
Quando chamar o veterinário
Any new feather loss or chewing. Emergency: bleeding, open wounds, or self-mutilation.
