Editor’s Note: The American Kestrel is part of the CROW CAW (Case A Week) series, which tells the stories of the patients at the Clinic for the Rehabilitation of Wildlife on Sanibel Island, the dangers they face, and how we can help protect all of our wildlife. Read previous cases here.
American Kestrels are the smallest falcon in North America and year-round residents in southwest Florida. Their diet includes large insects, small mammals, birds, and snakes.
This male American Kestrel, patient 24-4813, was brought to CROW because its wing looked injured. During his intake exam, CROW’s hospital staff noted that he was dehydrated, and his grip strength was weak–one side being weaker than the other. A blood test revealed this patient suffers from lead poisoning. Staff administered an IV, pain medication, and lubricant to help his dry eyes.
Lead poisoning is a serious threat to birds. Symptoms include weight loss, neck and limb weakness, muscle tremors, paralysis of the legs, and problems walking or flying. With birds of prey, like this American Kestrel, lead poisoning is often the result of the bird eating an animal (or animals) who have eaten lead shot or fishing gear.
While this patient was initially quiet in his enclosure, he is now progressing. His hydration is much better, and he is standing and vocal. CROW’s hospital staff continues to monitor his lead levels weekly, hoping to note improvements with each retest.
