Depending upon their method of work, some dogs (pointers and setters) are tasked to detect game, and some (spaniels) to purposefully startle ("flush") game. When the birds are forced to flee out of concealment and into the open, either by the hunter or the dog, the hunter then attempts to shoot down the birds on the wings to render them flightless, also known as "wingshooting". Once downed, the game is usually either incapacitated or immobilized, and is then retrieved with a dog (retrievers) or by the hunter himself.
