Your question could be answered from various points of view. My reply covers one:
One of the problems that buildings make for birds takes place when reflecting glass facades are utilized in buildings (especially high-rise buildings). Flying birds can't distinguish such huge solid objects, and consequently hit them. This may harm birds seriously. However, in some buildings this problem has been tackled by attaching stickers or other objects to the glazing so that birds can see them
