The Everglades is surrounded by human development, including the cities of Miami and Fort Lauderdale. Its wetlands and wildlife draw large numbers of birders, anglers, boaters, and other outdoor enthusiasts. The Everglades also provides critical, and often undervalued, benefits to people, called ecosystem services. The Everglades is internationally known for its extraordinary wildlife. More than 360 bird species can be found in Everglades National Park alone. The Everglades is known for its many wading birds, such as white and glossy ibises, roseate spoonbills, egrets, herons, and wood storks. It also hosts huge numbers of smaller migratory birds. Some birds, such as the snail kite, wood stork, and Cape Sable seaside sparrow are threatened or endangered species.
