Using archery to take game animals is known as "bow hunting". Bow hunting differs markedly from hunting with firearms, as distance between hunter and prey must be much shorter to ensure a humane kill. The skills and practices of bow hunting therefore emphasize very close approach to the prey, whether by still hunting, stalking, or waiting in a blind or tree stand. In many countries, including much of the United States, bow hunting for large and small game is legal. Bow hunters generally enjoy longer seasons than are allowed with other forms of hunting such as black powder, shotgun, or rifle. Usually, compound bows are used for large game hunting due to the relatively short time it takes to master them as opposed to the longbow or recurve bow. These compound bows may feature fiber optic sights, stabilizers, and other accessories designed to increase accuracy at longer distances. Using a bow and arrow to take fish is known as "bow fishing".
