This invention relates to an insulating glass (IG) window unit designed to prevent or reduce bird collisions therewith. The IG window unit includes at least first, second and third substrates (e.g., glass substrates). 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, and wherein at least two of the substrates are laminated to one another via a polymer-based laminating film (e.g., of or including PVB, EVA, or SGP) that may have a high UV absoprtion. The UV reflecting coating is preferably patterned so that it is not provided across the entirety of the IG window unit. By making the window more visible to birds, bird collisions and bird deaths can be reduced. The provision of the laminated substrates in the IG window unit is particularly advantageous for bird collision windows, because it can further reduce bird collisions by providing an increased contrast ratio, improve durability, and improve processing.
