Which symptom is NOT typically associated with lead poisoning?

Excessive feather shedding is not typically associated with lead poisoning in birds. Lead poisoning primarily affects the nervous system, blood cells, and kidneys, leading to symptoms that manifest through various physiological effects. Common symptoms of lead poisoning can include high blood pressure, weakness, and renal failure, all of which stem from lead's toxic effects on the body.

In avian species, excessive feather shedding could be indicative of other health issues, such as nutritional deficiencies, parasites, or environmental factors, rather than being a direct symptom of lead toxicity. Understanding the specifics of lead poisoning helps in identifying the correct signs and symptoms, highlighting that feather loss does not align with the typical manifestations of this type of poisoning.
