What creates the risk here
Sonnenahalli homes need anti-bird nets when west residential homes, university-side balconies, apartment pockets, open compound utility windows, and tree-side sit-outs face university-road dust, tree litter, scooter movement, crows, mynas, sparrows, and pigeons using shaded rails and roof corners. The issue is repeated mess from different birds around the same ledge, rail, pipe gap, drying side, AC pocket, or utility opening.
