The Danger
-
When a bird nibbles at cage bars, toxic materials may be ingested. Toxic cage materials become dangerous when a bird chews or nibbles on the cage bars, accessories or locks. This common behavior among birds results in the ingestion of potentially poisonous substances contained in the cage materials.
Zinc
-
Because brass contains zinc, zinc toxicity becomes an issue when a bird ingests flakes or bits of brass or brass coating material. Zinc toxicity can lead to liver, kidney and pancreatic damage and is sometimes fatal.
-
Copper
-
Copper is another metal in brass which is potentially toxic for birds. Although copper toxicity is not as common as zinc poisoning, copper nevertheless poses a threat when ingested.
Symptoms
-
Loss of appetite, excessive thirst, depression, dark green diarrhea and, with large birds, vomiting are signs that a bird may have ingested unsafe levels of zinc or copper.
Avoiding the Problem
-
Avoiding cage materials such as brass helps ensure a bird's health. To avoid the possibility of brass toxicity, bird owners should investigate a cage's materials before making a purchase. They should also take care to avoid cage accessories and toys which contain potentially toxic materials such as brass.
