Woodpeckers

Is it legal to require tenants to list their specific species when they're filling out a rental application, or could they potentially try claiming some sort of discrimination? The grandhuman is a bit upset that my woodpecker tenant has invited a batch of his woodpecker friends to move in here and install holes right next to his. Of course, I'm thrilled to have more tenants, but the grandhuman is complaining terribly. So, I was thinking if I knew the woodpeckers' species, well, did you know there are some woodpeckers you absolutely can't evict no matter what?
