How To Catch A Bunch Of Pigeons

There is nothing I hate more than cleaning my car and then having a pigeon poop on it.  Not to mention this type of thing usually happens within the first day.  However when I watched this video I couldn't help feeling sorry for these pigeons. 

These two fellows were hired by the city of Barcelona to help remove pigeons that were pooping on buildings and landmarks.  This is the coolest bit of net gun gadgetry I have seen in a while.  Video after the break.
