The National Aviary's Wetlands habitat is one of three immersive areas allowing visitors an unparalleled view into habits and behaviors of the birds living freely within the exhibit, including American Flamingos, Brown Pelicans, and Roseate Spoonbills.

Wetlands occur naturally on every continent except Antarctica, and play an important role in water purification, flood control, and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life.

The water found in wetlands can be saltwater, freshwater, or brackish. Subsets of wetlands include swamps, marshes, and bogs.
