Wetlands birds are a diverse group of species that inhabit areas with shallow water, such as marshes, swamps, and estuaries. Egrets, herons, and stilts are all examples of wetland birds. Egrets are long-legged wading birds with long, slender necks and long, pointed bills. Herons are also long-legged wading birds, but they have shorter necks and thicker bills. Stilts are small wading birds with long, thin legs and short wings. All three of these species can be found in wetlands around the world.
