Typical opening: Near Shivaji Nagar, anti-bird spans range from small AC or window closures to wider balcony and utility-side runs depending on the active bird route.
Building mix: shop-front ledges, mosque-side lanes, lodge balconies, compact service windows, and market-facing utility openings across Commercial Street, Russell Market, Infantry Road, and Cunningham Road side central market streets
Outdoor conditions: market dust, pedestrian crowding, delivery movement, crows, mynas, sparrows, and pigeons using signboards and old ledges, plus airflow, dust, drying use, balcony plants, and repeat bird movement near the opening
Common layout cue: Shivaji Nagar market-side bird control with central market anti-bird closure with signboard-edge reading, old-ledge returns, and quick-clean access
