Thousands of dusky seaside sparrows once inhabited the natural salt marshes around Merritt Island and the area along the St. Johns River in southern Florida.

From the 1940s onward, pesticides, pollution, and habitat loss caused the subspecies’ population to decline precipitously. By 1979, just six males remained. Why were the remaining birds eventually relocated to Walt Disney World theme park? Discuss
