Bird collisions with windows or other glazings are minimized or prevented with a glazing comprising as least one substrate with a UV reflectance coating deposited over the substrate in a patterned arrangement comprised of a plurality of stripes, and each of the plurality of stripes has a thickness that changes by 10 nm or less over every 1 mm in width. Such an arrangement of stripes having soft edges are less apparent, and thus more aesthetically pleasing, when compared with a similar arrangement of stripes formed with hard edges, while providing an effective deterrent to bird collisions. The glazing may also be utilized as part of a laminated glazing or insulated glazing unit. A method of manufacturing the glazing is also provided.

A coated article is provided, having a coating supported by a glass substrate where the coating includes at least one color and/or reflectivity-adjusting absorber layer.
