Feather Destructive Behavior
Også kendt som: Feather Picking, Feather Chewing, Self-Mutilation, Feather Plucking
Kort sagt
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. Fuglen tygger, plukker eller beskadiger egne fjer af medicinske eller stressrelaterede årsager; systematisk dyrlægeudredning kræves.
Fjertab på kroppen med intakt hoved er det klassiske mønster.
Hvad er det?
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.
Årsager og risikofaktorer
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.
Tegn
- Intact head feathers (cardinal)
- Chewing under wing, thighs, or breast (common)
- Unilateral pattern (occasional; may suggest local pain)
- Skin self-mutilation (emergency)
Tyggede skafter og blottet hud: aktiv ødelæggelse, ikke normal fældning.
Diagnostik
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.
Behandling
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.
Prognose
Excellent if medical cause resolves early. Guarded in chronic habit; follicles may be permanently damaged. Untreated self-mutilation: guarded to poor.
Forebyggelse
Ongoing enrichment, stable routine, quality formulated diet, annual avian exams, avoid aerosols, PTFE fumes, and heavy-metal toys.
Hvornår ringe til dyrlægen
Any new feather loss or chewing. Emergency: bleeding, open wounds, or self-mutilation.
