Collisions between birds and buildings represent one of the most significant yet under-recognised human-induced causes of avian mortality worldwide. In the United States alone, it is estimated that over one billion birds die annually from such collisions. This concern takes on particular significance in India, which supports extraordinary avian diversity, with over 1,380 recorded species, including numerous endemics and globally threatened taxa and lies at the crossroads of major global migratory flyways, most notably the Central Asian Flyway, used annually by millions of birds moving between Arctic breeding grounds and the wetlands, forests, and grasslands of the Indian subcontinent.
