>>884323You should probably look at break barrel ones, that way you don't have to pump them 20 times to take down a sparrow. Gamo makes a lot of nice stuff for like $100-$150.
There's a co2 Crosman rifle, I think 1077? That one is fun for going after birds because you don't have to pump it every time. I have taken out a opossum with it. You will get around 20 shots from a co2 cartridge before it significantly loses power.
