How is birdshot characterized in terms of its design and purpose?

Birdshot is characterized by its design and purpose as being specifically created for bird hunting, utilizing multiple small pellets that spread out upon firing. This spread is advantageous when targeting birds in flight, as it increases the chances of hitting a moving target over a wider area. The small pellets are effective for quail, pigeons, and other small game, as they minimize the risk of damaging the meat while still being lethal enough to bring down the bird.

In contrast, the other options do not accurately reflect the intended use or design of birdshot. A single solid pellet describes a type of ammunition more in line with slug rounds, which are used for larger, more dangerous targets. Buckshot, which consists of larger pellets, is intended for larger game and personal defense rather than small bird hunting. Lastly, while birdshot can be used for target practice occasionally, it is not exclusively designed for this purpose, as its primary function is hunting small game.
