Avian Botulism

Avian botulism is a neurological disease affecting birds, caused by the ingestion of toxins produced by the bacterium Clostridium botulinum. This bacterium produces several types of botulinum toxin, which can paralyze the muscles of affected birds, leading to symptoms such as weakness, inability to fly, difficulty swallowing, and loss of coordination. The condition often arises in wetland habitats, where decaying organic matter provides ideal conditions for the bacteria to thrive. Bird populations, especially waterfowl and shorebirds, can suffer significant mortality during outbreaks. Avian botulism is typically associated with environmental factors, including drought or flooding, that lead to the accumulation of decaying material and conditions for the bacterial proliferation. The disease contributes to wildlife management challenges, particularly in maintaining healthy bird populations in affected ecosystems.
