And I never thought of you as trying to portray such a standard. We have to work within the confines of the written word only and it can lead to misunderstandings.

Another curious tactic used is to stick a couple of decals (about a metre in diameter each) that resemble open eyes towards the base of the wind towers. This apparently puts off eagles because they don't like to be stared at so they fly away from the towers. I have not seen any studies that completely confirm their effectiveness but I know the staring eyes were being used in Spain a few years ago along with the black blades. by one of the major power companies there.
