Abstract: Clear or tinted window panes of glass or plastic having a pattern of dots, vertical lines, horizontal lines or a combination of vertical and horizontal lines in a regular pattern on a surface of the pane, the pattern being visible to the avian eye to prevent birds from striking or colliding with the window pane and having optical characteristics of a minimum of 20% ultraviolet reflection separated by ultraviolet absorption.

Abstract: Through various means, a visible or invisible uniform pattern to the normal human eye is created in sheet (flat pane) glass or plastic. The patterns are visible to the normal avian eye but may or may not be visible to the normal human eye. The elements forming the pattern: (1) uniformly cover an entire pane (sheet) of flat glass or plastic, (2) are of any shape or size, and (3) are separated by 5 centimeters (2 inches) or less and arranged in horizontal rows, vertical columns, both horizontal rows and vertical columns, or any other parallel arrangement of elements with similar spacing and variously angled from either or both the horizontal row and vertical column orientation. The elements forming the pattern are visible to birds viewing clear or tinted sheet (flat pane) glass or plastic. The patterns create a visual warning about the glass hazard in the environment.
