The one that the man is carrying!
410 or 20 gauge, the make of the gun depends on what you like
It will depend on what you are hunting and which brand of shell your shotgun patterns best.
I would use either a modified,or improved cylinder,choke for close in small bird hunting.

A shotgun is the only legal firearm for duck hunting in the US.
a rifle.Please ignore the previous answer.The best firearm for hunting game birds is a shotgun.They come in single shots,pump action,semi-auto,over under,and side by side configuration.You will have to decide which fits you best.most upland birds are hunted with a 20 gauge,while most bigger birds including pheasent,and geese will best be served by a 12 gauge shotgun.
modified
The best deer hunting gun you can use Ceaser Garuni. That gun is all good and all but it is too expencive and so if you want a great gun and you don't want to waste money you need a Browning BPS Deer Hunter. deer hunting is boring go for birds!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You must keep hunting. Catching birds or chimpowaws works best.

You would have to define best for WHAT? A .300 Winchester Magnum may be a great gun for shooting at 900 meters, but is useless for hunting birds in flight. The over and under shotgun is great for birds in flight, but hard to carry under a jacket as a defensive firearm. Bottom line- there IS no ONE best firearm.
