My street has a lot of pigeons and they cause a lot of problems. Most houses on the street are back-to-back design, built around 1900s when it was a popular way of cramming large numbers of people into an urban space, with slate roofs and flat roofs over dormer bedrooms. Every roof has large amounts of bird poo, showing where the birds try to hide from the wind. My house recently had a few slates missing and the pigeons got into the roof-space to nest. Since the slates were immediately above (and behind) the dormer bedroom, I couldn't see the hole until one day part of my ceiling fell in because of water damage, from said hole. After I got the roof fixed, some of the pigeons were trapped in the roof and came out through the only gap left - into my spare bedroom. Between getting the windows open and setting most of them free, a couple were so dazed by the experience that when I manhandled them out of the window, they fell like bricks, 30 feet to the ground and promptly expired. However, I still want to teach them a lesson. I guess that shooting an air rifle in a crowded urban location will get the attention of the police pretty quickly so I'm looking for another way to kill the b*stards. Oh and is it legal to kill wild pigeons?
