Claims
- *[Paraphrased derived summary — non-Open-Access source.]* Lead poisoning is common in pet birds and free-ranging birds (especially waterfowl). In pets it usually follows ingesting household metals — blinds, costume jewelry, mirror backings, bird toys, hardware cloth, curtain weights.
- *[Paraphrased derived summary — non-Open-Access source.]* Zinc poisoning is also frequent in pet birds. Sources include galvanized toys, chains, mesh, bells, keys, and pennies (post-1982). Galvanized wire is mostly zinc but may also contain lead.
- *[Paraphrased derived summary — non-Open-Access source.]* PTFE (polytetrafluoroethylene) gas poisoning is common in birds kept in or near kitchens: overheated nonstick cookware releases the gas at about 280°C (536°F).
- *[Paraphrased derived summary — non-Open-Access source.]* Ingested lead breaks down in the ventriculus and is then slowly released into the GI tract and bloodstream.
- *[Paraphrased derived summary — non-Open-Access source.]* Lead is stored in soft tissue and bone and is excreted slowly over time.
- *[Paraphrased derived summary — non-Open-Access source.]* Lead poisoning disrupts many biochemical processes in birds.
- *[Paraphrased derived summary — non-Open-Access source.]* Signs vary with dose and may include anorexia, weight loss, regurgitation, diarrhea, depression, ataxia, weakness, seizures, blindness, polyuria, and polydipsia.
- *[Paraphrased derived summary — non-Open-Access source.]* Diagnosis rests on clinical signs, biochemical and hematologic findings, blood lead levels, and imaging.
