Hang ribbons or other material in strips no more than five centimeters apart on the outside of windows for the full width of the glass. Use window film which reduces the reflection and transparency of the glass but still allows you to see through your windows from the inside. Since hawk silhouettes work much better when they move, make your silhouettes from sheet aluminum or wood and hang them by chain or rope from an overhang. Etch images onto the exterior surface of glass. When building a dwelling or replacing a window, install the window angled downwards so as to reflect the ground.
Most birds naturally avoid webs.
If the attractant is very close to the house, the bird cannot build up enough momentum to injure itself should it hit the window.
