That’s One Way to Deal With a Problem

When I was in grad school, I remember several conversations across many classes on building against infestation, both external and internal. We learned about innovative ways different museums discouraged bird roosting on their buildings.

I must say, though, for all the ways we discussed in class, none seem to be as interesting as the National Park’s new method for keeping birds out of Casa Grande. They’ve trained a hawk to scare off other birds, and are taking actions to encourage other raptors into the area to help.

This seems like a very non-lethal, environmentally sound idea. My question, though, is how are they keeping the raptor excrement from replacing the problem it was supposed to be helping stamp out?
