Abstract
A window unit is designed to prevent or reduce bird collisions therewith. The window unit may include first and second substrates (e.g., glass substrates) spaced apart from one another, wherein at least one of the substrates supports an ultraviolet (UV) reflecting coating for reflecting UV radiation so that birds are capable of more easily seeing the window. The UV reflecting coating is preferably patterned so that it is not provided across the entirety of the window unit. By making the window more visible to birds, bird collisions and bird deaths can be reduced. The UV reflecting coating is designed to have high UV reflectance across a large range of viewing angles.
