I think you have to understand that some of these birds look at the farmers' fields as very easy to get at and free food. In a natural habitat, they would be foraging somewhere else. I think one of the things we've seen develop over the years is that the wildlife have become very adapted to finding an easy and cheap food source, and farmers' fields are that source. Putting things like cannons in place is not designed to harm the birds; it's designed to move them to a more natural habitat to do the feeding. Maybe the birds are a little bit like us. They're sometimes a little bit lazy to go and work for their food. The cannons are only designed to move them there.
I can actually give you a concrete example on our own farm. Thirty years ago, we had very few sandhill cranes in our area. You might have seen one or two. Now there will be thousands and thousands of them that come. One of the big challenges we have now is when we plant corn. When the corn comes out of the ground this far, they don't just snip it off; they pull it out by the roots, and they'll just walk right down the rows. But if you put the cannons in and chase them off, they'll go into the wetlands and other areas and find their food there. It's just a matter of recognizing that it's the economic value that has to be considered on the agricultural side, that there are times when we have to move those species someplace else.
