Clear and reflective architectural glass in residential and commercial structures in urban, suburban, and rural landscapes can be a passive invisible killer of birds worldwide. Our collective evidence reveals that clear and reflective windows of all sizes are theorized to be invisible to potentially all birds due to what have been defined as fly-through conditions, reflected habitat conditions, or black-hole effect. The amount of glass and associated vegetation that attract potential victims best explain the number of casualties at any specific building.
