    Officials said they suspect water contamination as one of the reasons for the deaths but were awaiting viscera test reports.
    Thousands of migratory birds of about ten species were found dead around Sambhar Lake, the country’s largest inland saltwater lake near Jaipur, sending shock waves among locals and authorities.

    Officials said they suspect water contamination as one of the reasons for the deaths but were awaiting viscera test reports. Though the official toll was 1,500, locals claimed the number of dead birds could be as high as 5,000.

    “We have never seen anything like that. Over 5,000 birds died mysteriously all over the place,” 25-year-old Abhinav Vaishnav, a local bird-watcher, told PTI.

    They alerted state forest officials who found around 2,400 dead birds -- including 20 migratory species that flock to the lake each year.
    ...
    So far, wildlife authorities haven't established the cause of the deaths. But one possibility is high saline and alkaline levels in the water, in an area where salt is manufactured, according to Ashutosh Arora, a senior official in the state's Animal Husbandry Department.

    The samples have been sent for analysis, said Ashok Sharma, joint director of the State Disease Diagnostic Center. "At this moment we suspect that there was some level of toxicity and high level of salinity in the drinking water -- we will have more details once the report comes from Bhopal," said Sharma.

    Thousands of migratory birds affected in the last week.
    After the death of hundreds of migratory birds in the marshland of Rajasthan’s Sambhar Salt Lake, environmentalists here have called for urgent action to find out what is causing the loss of avian lives. The decomposed carcasses of birds have indicated that the deaths had occurred over the last one week.

    The dead birds belonged to about 10 species, which migrate annually to water bodies in India from the cold northern regions of Central Asia. The Sambhar Salt Lake, situated 80 km south-west of Jaipur, is the country’s largest inland saline water body which attracts thousands of migratory birds every year.

    Tourism & Wildlife Society of India (TWSI) honorary secretary Harsh Vardhan, who visited the lake on Tuesday, told The Hindu that the carcasses were collected in a tractor-trolley and buried in a ditch.

      Bacterial infection may be behind Sambar bird deaths, says Bikaner institute
      The death toll of birds on Thursday rose to 4,800 around the lake spread across 198 square kilometers, with the forest department disposing 538 bird carcasses. The forest officials said the death toll could rise in the coming days once a search for dead birds in the water starts.

      A Bhopal-based laboratory has ruled out avian flu as the cause of deaths of birds in India’s biggest inland salt lake at Sambar, in Rajasthan, even as a Bikaner-based institute has said bacterial infection that spreads among birds could be the possible cause for the deaths, officials said on Thursday.

      The death toll of birds on Thursday rose to 4,800 around the lake spread across 198 square kilometers, with the forest department disposing 538 bird carcasses. The forest officials said the death toll could rise in the coming days once a search for dead birds in the water starts.

        Apreliminary forensic report has indicated that the mysterious death of more than 4,800 migratory birds at the country's largest inland water saltwater lake near Jaipur was caused by botulism, a serious and fatal illness that affects the nerves, officials said on Friday.

        A 70-member disaster management team is at Sambhar Lake, a key wintering area for tens of thousands of migratory birds, to dispose of the carcasses so that botulism does not spread to other birds. Also, a dozen teams from the Animal Husbandry Department are closely monitoring the situation.

        Initially, it was suspected that the birds died due to avian flu but the report from a laboratory in Bhopal has ruled this out.
