Peck is a term that can refer to a variety of meanings, but it is commonly associated with a small, quick bite or strike, often made by birds. For example, birds like sparrows and woodpeckers use their beaks to peck at food or surfaces. This action helps them forage for insects or seeds and can also be a way to communicate or establish territory. In another context, "peck" is a unit of measurement for dry volume, primarily used in agriculture. One peck is equivalent to about 8 dry quarts or 9 liters. It is often used to measure fruits and vegetables, such as apples or peaches, when sold in bulk.
