The endangered Cape Sable Seaside Sparrow is one of South Florida's most imperiled species. The range of the diminutive bird is found almost entirely within the boundaries of Everglades National Park. Because sparrows construct their nests near the ground, the artificial manipulation of water in these areas can have significant implications for breeding populations.

As Everglades restoration moves forward, the health of sparrow populations can serve as a relative indicator of success. Proper management decisions rely upon the best science possible. Over the years, CESI has funded several intensive studies on the natural history and status of the sparrow. This project documents some of the most exhaustive research ever conducted on the species.
