What is a common symptom of lead poisoning in raptors?

Shaking and weakness are indeed common symptoms of lead poisoning in raptors. When a raptor ingests lead, either through prey that has been exposed to lead or by scavenging carcasses or fragments containing lead, the toxic metal disrupts various physiological processes. One of the critical impacts of lead is on the nervous system as well as muscular functions, leading to tremors or shaking, and a general weakness due to the bird's inability to coordinate movements properly. This can hinder their ability to hunt or fly effectively, severely impacting their health and survival.

Other symptoms associated with lead poisoning can include lethargy and other neurological symptoms, but shaking and weakness are particularly prominent because they directly reflect the influence of lead on the nervous system and muscular control. These signs are crucial for falconers and wildlife rehabilitators to recognize, as timely intervention can be life-saving for affected birds.
