Typical opening: Around Kothanur, anti bird net work: 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: north-east apartments, villa lanes, Hennur-side balconies, basement stilt windows, and shaded utility openings across Hennur, Thanisandra, Nagawara, and K Narayanapura side north-east homes
Outdoor conditions: ramp airflow, tree litter, damp shaded corners, crows, mynas, sparrows, parakeets, and pigeons using slab edges and rails, plus airflow, dust, drying use, balcony plants, and repeat bird movement near the opening
Common layout cue: Kothanur shaded-slab bird hygiene with north-east anti-bird closure with ramp-side reading, shaded-corner returns, and breathable finish
