Yes I am. And if you can't see the fact that it isn't the size it's the flash that attracts them then you are stuck on stupid. The original version is the most effective and it's just a large flat blade that spins. The blades are anywhere from 5' long to in some permanently built cases 12' long. Ever seen a duck with a 12' wingspan. And like I said earlier, if you don't shoot and scare the duck they often just fly right into the blade. Ever hear of flagging geese? Where guys stand out in a field with a large white cloth tied to a pole and they wave it back and forth in the air to bring geese in.
Waterfowl and raptors have some of the best eyesight in the animal kingdom. Their center vision is 10X and their peripheral vision is normal. They can see a grain of corn on the ground from 60 yards away. With that kind of eyesight you think a bird can't tell the size of something as large as a windmill blade? Of course they can, it's not about the size it's all about the flash.
