The Nilgiris District in Tamil Nadu is home to a rich biodiversity and a large population of tigers. However, in the past two months, 10 tigers have died in the district due to various reasons.

  • This has raised concerns among conservationists and officials about the welfare and survival of the big cats.

What are the Reasons for Tiger Deaths in Nilgiris?

  • Starvation and Infection:
