Accelerated development of water-control structures and unnatural water-delivery schedules in the 1960s has sharply reduced the number of birds since that time. Modern water-control programs in south Florida have so greatly changed the flooding and drying patterns of the Everglades that the survival of Wood Stork nesting colonies is in question. The Everglades of the 1930s, largely undrained and without complex water-control structures, supported a nesting of population of 5,000 to 15,000 pairs of Wood Storks. Hydrologic conditions resulting from water-management activities in recent years often have been unfavorable to support Wood Stork feeding and nesting requirements.Ī Wood Stork is easy to identify by its black, bald head. When the natural hydrologic cycle is upset by human-controlled water-management activities, Wood Storks fail to feed and nest successfully because a breeding pair of Wood Storks will not attempt to nest if sufficient food is not available. The feeding behavior of Wood Storks has evolved over many thousands of years to reflect the natural conditions of the Everglades.

In the marsh habitat of the Wood Stork, the effectiveness of this feeding technique increases as fish are concentrated in pools by seasonal water-level declines that result from the prolonged winter dry periods. Each breeding pair of these large birds requires about 440 pounds (200 kg) of fish per breeding season. Its bill snaps shut with a 25-millisecond reflex action - the fastest known for vertebrates - whenever it touches prey. The stork sweeps its submerged bill from side to side as it walks slowly forward.

Often the water is muddy and full of plants, conditions that obscure prey from sight. A stork locates food - mostly small, freshwater fish - not by sight but by tactolocation, or groping with its bill in shallow water. The Wood Stork used to thrive in south Florida because it is a specialized species that prefers tropical and subtropical habitats with distinct wet and dry seasons. Storks were once more abundant in the wetlands of south Florida than in any other region throughout the southeastern states.

When it touches prey, its bill snaps shut with a 25-millisecond reflex action.Īlthough the status of the Wood Stork has been downlisted from endangered to threatened, the Everglades ecosystem is still endangered. Because it is much easier to count and record the biology of one or more indicator species than it is to measure the more complex workings of an ecosystem, close monitoring of carefully selected species provides important information about the health of the entire system.Ī Wood Stork feeds by tactolocation, which means by groping with its bill in shallow water. The quality and quantity of the required environment directly determines the well-being and the number of that species. Indicator species serve as excellent messengers of the past, present, and future because their specific habitat requirements are so closely associated with one particular environment. The Wood Stork serves as an indicator species for restoration of the Everglades ecosystem.

The species was downlisted from endangered to threatened in June 2014, reflecting a successful conservation and recovery effort spanning three decades. It is the only stork breeding in the United States and was placed on the Federal Endangered Species list in 1984. The Wood Stork ( Mycteria americana) is a large, bald-headed wading bird that stands more than 3 feet (0.9 meters) tall, has a 5 foot (1.5 meter) wing spread, and weighs 4 to 6 pounds (1.8 to 2.7 kg).
