below information refers to the mainland india, i.e., excluding andaman, nicobar and other islands.

mainland india holds 1222 species of birds from 100 families.

though the region is not most species-rich globally, it is perhaps family-richest, an equally important aspect of avian diversity.

an attempt to share a few aspects of this richness from a threat-to-extinction point of view.
