Cats also don't work. The pigeons eventually kill them by pretending not to notice then flying away at the last moment while the cat is in mid air. The cat then plunges n stories down again and again.

I don't think the pigeons will attack your network any time soon in the foreseeable future.

I'm very disappointed there is no video of this weapon in action.

A fun expansion would be to play a soft sound before shooting for familiar customers.
