The Hidden Threat: Indian Birds Colliding with Glass Structures Lack Research and Data

In India, an increasing number of birds are falling victim to collisions with glass surfaces, a silent crisis that has yet to be systematically documented. The plight of these avian creatures is particularly concerning given the lack of comprehensive data on the phenomenon, which has been well-studied in other parts of the world, such as North America.

Peeyush Sekhsaria, an architect and passionate birdwatcher, recalls an unsettling incident from 2007. While at a tourist lodge in Coorg, he heard a thunderous ‘blast-like sound’ as an emerald dove flew into a window. This was not a sleek modern skyscraper, but a regular building, highlighting that the danger extends beyond urban environments to various structures throughout the country.

The fundamental issue lies in how birds perceive glass. Transparent panes can appear as unobstructed airspace to them, while reflective surfaces mimic the appearance of trees and sky. This creates a deadly illusion, leading to fatal collisions that occur at high speeds. The absence of data makes it difficult to understand the scale of this problem in India. In stark contrast, studies in North America estimate that over a billion birds die each year due to similar accidents.

Sporadic reports of bird collisions have emerged across different states in India. For example, in Gujarat, incidents involving migratory rosy starlings crashing into glass were reported, while in Meghalaya, long-tailed broadbills were found dead after hitting a car showroom’s glass façade. These occurrences often circulate informally within birdwatching communities and social media platforms but lack formal documentation.

Ecologist Ashwin Viswanathan from the Nature Conservation Foundation emphasizes the urgent need for research on this issue. Without systematic data collection and analysis, the real impact of glass collisions on bird populations in India remains largely unknown. As urbanization continues to escalate and glass façades become more prevalent in architecture, there is a pressing need for awareness and mitigation strategies to protect our avian friends.
