They're clever birds but people have some luck with special traps and also
sometimes with shooting them (I tried the latter earlier this spring with an
air rifle but never had any luck hitting the target). The males are the ones
you really want to eliminate.
Anyway, you can learn much more about this and related issues if you

I too have a bunch of those terrorist birds and would love to hear anyones
advice of getting rid of them ...... as in KILLING them!!!
Two days ago I had a terrorist bird (house sparrow) peck a hole in the sole
tree swallow egg in the nest box close to my house and throw it on the
ground. He then began attacking the female swallow in her box. He's not
bothering them any more and there are now two eggs in the box.
