My dad hated the Bulbuls that would nest in the orange tree that was outside his bedroom. He bought a pretty nice air pistol and scope just for them. 
I've seen the pigeon ticklers mentioned below. They them all over where the birds like to roost, esp high up in steel hangars. Everytime I see them, I think to myself, "who the hell gets to go up there and get those stinking flying rats down". It's funny too, because I've only seen pigeons skewered in them. Guess other birds are smarter and stay away. Haha
Pigeons are the reason the term “Bird Brain” came about.

The pest control guy had metal mesh, about quarter inch openings and about 6” wide in about 10’ long rolls. He used self tapping screws to attach it like a skirt. Before he attached the skirt he used a garden hose and a brush on a long stick to flush all the pigeon droppings, nest, eggs, etc. down my rain gutters. Then he flushed the rain gutters out of all that crap. He sprayed disinfectant around as well. He also used the mesh to cover a couple of areas where the roof made perfect pigeon nesting areas. He (NAZ Pest Control) charged me $200 for the whole job. He estimated 87 linear feet and 2 hours to do the job.
His competition (Friendly Pest Control) came out on Tuesday morning (8:00am) and was 30 mins late, didn’t call to let me know he would be late, and didn’t get me the estimate until late Wednesday afternoon. Within 5 minutes of Friendly leaving my house, his office texted me and complained that my Hawaii phone number was coming up an international number and they couldn’t call me from their business phone. Then they went on to ask me to contact them so they could set up a date and time for their guy to come out for an estimate. Since their guy had just left I ignored their text. Then on Wednesday late morning I got an e-mail from them letting me know that they scheduled their guy to come out on Thursday to give me an estimate. I finally called them and asked them why I had not gotten my estimate yet. And they said because their guy had not come out yet. And I told them their guy was out on Tuesday morning and was late and I still don’t have an estimate. Then I asked her why they were so confused? So she says, let me straighten this out and I’ll call you back. I told her I don’t want a call, I want the estimate they promised me. Then late Wednesday afternoon I finally got an email from the owner apologizing for the confusion and he attached the estimate. The estimate was for 185 linear feet, didn’t state how many hours it would take and came out to $1,467.00. What they don’t know is that when they finally sent the estimate NAZ Pest Control was already on my roof doing the work.
By 6:00pm NAZ had sent me his invoice and I paid it with my credit card.
Funny story. Back in the 80’s I worked all over Los Angeles. In downtown LA near the 10 and 110 intersection is a small lot with both McDonalds and Burger King side by side. They shared the parking lot. The route into and out of the lot was in between the buildings. And of course they had outside tables. It was not uncommon for the pigeons to come up to the tables looking for food. Only something was weird about these pigeons. They were totally FAT AND GREASY LOOKING!!! When the cars drove in and out they didn’t fly to get out of the way. They ran. Maybe because they couldn’t fly? I don’t know. But I have never seen pigeons like this before. It goes to show you what a continuous diet of French fries will do to you.
