Water levels are tightly managed in many wetland regions in South
Florida, with flood gates controlling water flow in parts of the Everglades. The flood gates were opened after heavy rains in the winter of 2016, inundating areas where water levels have been relatively low for decades. Sparrows in

This bird requires aquatic prairie with low water levels and open areas. Sea level rise, alterations in water flow caused by water management practices in South
Florida, and natural processes such as hurricanes, have caused water level changes and flooding, reducing available habitat.

Courtship behavior includes males chasing females and offering them food and nesting materials. Females may initiate the process by approaching males and begging. Male and female raise their clutch of young together, and may remain together for the next clutch.

The Cape Sable seaside sparrow is 13 to 14 centimeters (5.1 to 5.5 in) in length. The back is dark olive-gray and the tail and wings are olive-brown. Adults are light gray on the belly to almost white with dark olive-gray streaks on the breast and sides.

The bird is strongly influenced by water levels. Water level rise effectively halts breeding activities, in part because nests are suspended just off the ground. Daily water level shifts even affect behavior, subduing vocalizations by territorial males.
339:
Males are very territorial, claiming a patch of prime breeding habitat and defending it. Most vocalizations are produced by the males, which perch and call loudly to defend territory and advertise to females.
