The cause of 17000 birds dying at Sambhar lake in Rajasthan was botox, which led to avian botulism, a report said. Botulinum toxin, better known as botox, paralyzes muscles.
Birds were found paralyzed over wings and legs, showing neck-drooping syndrome. “Omnivore and insectivore species were most affected,” said the investigation report submitted on Thursday by the Indian Veterinary Research Institute (IVRI) on migratory birds at Sambhar.
Late October, Rajasthan woke up to one of India’s worst avian catastrophes. There were bird carcasses on the banks of the Sambhar Lake, a 230 square kilometer saltwater body. Birds died at a fast rate.
