Year after year, the condition of birds, which are one of the most obvious indicators of the state of the natural environment, is deteriorating further, due to factors like habitat destruction and unsustainable development over the last couple of decades.

The latest Red List of birds released by International Union for Conservation of Nature (IUCN) for 2015 shows that a total of 180 bird species in India are now threatened, as against 173 last year. Only one species has moved out of the Red List.
