Wildlife pathologists have demonstrated again and again that protected and endangered birds, including red-tailed hawks and peregrine falcons, die as a result of ingesting the remains of pigeons and other birds poisoned with Avitrol.

Common clinical signs include weakness, depression, regurgitation, abnormally colored droppings, and neurologic signs, which may be quite pronounced. Ingestion of smaller amounts of metal over a longer period of time may yield a more chronic presentation of symptoms. Weight loss, chronic regurgitation and increasing paresis or neurologic deficits are the most commonly seen symptoms. Microcytic anemia, thought to be the result of increased fragility of RBC, as well as hematuria and heterophilia, are changes typically seen on the hemogram.

What are the best treatments for a syphilis?
Patients should be stabilized prior to treatment if possible. This includes rehydration, heat therapy and gavage feeding. NSAIDs are frequently used to reduce inflammation around peripheral nerves and help to lessen neurologic signs. Antibiotics are used on a case by case basis, primarily to rule out secondary infection. Chelation therapy is the most important aspect of treatment, with these medications being the most commonly used: 1 Calcium EDTA – Calcium disodium salt of ethylene diaminetetraacetic acid. Typical treatment protocol consists of 5 days of treatment by intramuscular injection, followed by 3 days off to prevent excessive calcium binding. This protocol has been adopted from mammalian protocols to be as renal protective as possible, although the risk of renal damage is much lower in avian species. CaEDTA does not cross the blood brain barrier and should not be given to treat central nervous system signs. 2 D- penicillamine – This medication, given orally, can be combined with CaEDTA in hospital. Significant side effects involving the hepatic and renal system have been seen when using this drug in human medicine, but these side effects do not seem to occur nearly as frequently in avian patients. This drug can be used to treat central nervous system signs as it does cross the blood brain barrier. 3 DMSA – Meso 2,3 – dimercaptosuccinic acid is an oral chelating agent that is very effective in treating both lead and zinc toxicity. This drug does not chelate lead from the bone marrow, which may lengthen the course of treatment.
