Their loud call, a harsh “kek-kek-kek” note, often elicits a clattering chorus of responses. A subspecies of the clapper rail found only in the Florida Keys, the mangrove clapper rails are genetically distinct from clapper rail population found elsewhere in the state. Species Status Assessment Class: Birds Family: Rallidae Scientific Name: Rallus elegans Common Name: King Rail Species synopsis: King rail is closely related to clapper rail (Rallus longirostris) and interbreeding between the two has been the subject of considerable scientific speculation. Clapper Rails have inconsistent pigmentation among individuals, but both females and males can be identified by a grayish-brown body with dark stripes lining the belly. by Genevieve Nuttall Conserving healthy future habitat in the Florida Keys as sea levels rise and human communities begin to shift is important for this species. Current regulations have helped population numbers remain stable, but Clapper Rails are still susceptible to the effects of wetland pollution and degradation, and they will not thrive in damaged marsh areas. The northern range of Clapper Rails does not extend much past Connecticut, so we are lucky to have the opportunity to see these birds in our state!

This degree of specialty may limit this bird’s ability to adapt to new sources of food in shifting ecological communities due to climate change. Flight is low and fluttering over short distances. Restoring high elevation marsh areas, including following a major storm or disturbance event, is an important aspect of protecting mangrove clapper rail nesting habitat. Each species account is written by leading ornithologists and provides detailed information on bird distribution, migration, habitat, diet, sounds, behavior, breeding, current population status, and conservation.
