Midwestern US Forest

The lush, green forest is coming alive under the canopy of bird calls. Birds of varying sizes and colors and beginning their daily ritual of call and response. Among the branches of dense trees, patches of color can be seen as their wings beat gracefully in midflight. A forest, also referred to as a wood or the woods, is an area with a high density of trees. As with cities, depending on various cultural definitions, what is considered a forest may vary significantly in size and have different classifications according to how and of what the forest is composed.[1] A forest is usually an area filled with trees but any tall densely packed area of vegetation may be considered a forest, even underwater vegetation such as kelp forests, or non-vegetation such as fungi, and bacteria. Tree forests cover approximately 9.4 percent of the Earth's surface (or 30 percent of total land area), though they once covered much more (about 50 percent of total land area).
