There are these:

Either of these should put an end to a feral pigeon. The Urban is make in the UK by BSA (owned by Gamo) and has a superbly made barrel and it is essentially an all metal rifle, very high quality. The new Arrow is mostly plastic but reports are it too is accurate. It is not a BSA made rifle. Both will need a pump or other high pressure air source to operate them. No recoil, very quiet, very accurate. The Urban runs around 22 to 30 fpe depending on how it is set up. I think the Arrow is running around 18 fpe (foot pounds of energy) as delivered.
Consider that CCI .22 CB Short is 32 fpe at the muzzle, the Gamo Urban is right there at reaching up to 30 fpe. Most of your little springers in the .177 size and even .22 are running about 12 fpe. A healthy Benjamin 392 at 8 pumps is about 14 to16 fpe.
