Feather Destructive Behavior

TL;DR. Burung mengunyah, mencabut atau merosakkan bulunya sendiri kerana sebab perubatan atau stres; siasatan veterinar sistematik diperlukan.

Kehilangan bulu pada badan dengan kepala utuh ialah corak klasik.

Apakah itu?

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.

Punca dan faktor risiko

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.

Tanda

• Intact head feathers (cardinal)
• Chewing under wing, thighs, or breast (common)
• Unilateral pattern (occasional; may suggest local pain)
• Skin self-mutilation (emergency)

Batan dikunyah dan kulit terdedah: kemusnahan aktif, bukan molting normal.

Diagnosis

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.

Rawatan

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.

Prognosis

Excellent if medical cause resolves early. Guarded in chronic habit; follicles may be permanently damaged. Untreated self-mutilation: guarded to poor.

Pencegahan

Ongoing enrichment, stable routine, quality formulated diet, annual avian exams, avoid aerosols, PTFE fumes, and heavy-metal toys.
