ABSTRACT:
A passive method for protecting flying birds against the danger of colliding into transparent barriers is disclosed. The method involves placing on the transparent barrier an image of the center portion of the web of an orb web building spider especially including in the image an adornment on the web known as the stabilimentum. The stabilimentum is known to be an advertisement by the spider for the purpose of deterring birds from flying into the web, an event which both animals wish to avoid. When the spider web image is placed on the transparent barrier, flying birds will take evasive action and thus avoid harmful collisions. Since the spider web image is mostly transparent, it does not block out a large portion of the transparent barrier.
