Yes, but the first shot would damage it. A few shots will kill it. I think it's illegal to kill a bird without a special license to hunt/kill animals.
Nerf gun
400fps can kill a bird from about 10 yards away. I have a 880 powerline daisy It will go through the bird. So ya it can
Yes
you can kill a cat,dog,bird,possibly a person that's all i know
350FPS would be sufficient
It is likely. a close range headshot would do the trick.
Not likely, but it could. You could kill someone by throwing a rock at them. Worked for Goliath.
Yes. So could a gun
Yes it potentially could.
The matter of fact is that no an airsoft gun can not kill a person, but it can kill insects such as ants, butterflies, and leaves, also paper, and plastic toilette paper are in harms way. Unless you beatn sombody with the butt of the gun mercelessly until they suffered so much head trauma they died
A Daisy Buck BB gun can potentially kill a bird if it hits a vital organ or causes significant trauma. However, it is not recommended to use this type of gun for hunting birds as it may not provide a humane and quick kill. It's best to use appropriate firearms or air rifles for hunting birds.
Machine Guns, like any other gun (with the possible exception of an air soft gun) could seriously harm, and even kill you if at point blank range. Any gun could kill you, so, yes. a machine gun is powerful.
