100,000 - 1,000,000 individuals
Comments: Total adult population size is unknown but presumably exceeds 100,000 (BirdLife International 2010).
The U.S. population comprises less than 10 percent of the global population (Meyer and Collopy 1990). Meyer (1995) estimated U.S. population at 800-1,150 pairs, or about 3,200-4,600 individuals at the end of the breeding season (Meyer and Collopy 1990). Florida probably supports 60-65% of the U.S. population (Meyer 1995). South Carolina's population, which lost more than 70% of known nesting habitat in 1989 because of Hurricane Hugo, has about 10-15% (or 110 pairs) of the total U.S. population; other southeastern states probably have fewer than 100 pairs each; no known data for other populations.
