Clapper Rail Identification, All About Birds, Cornell Lab of

The loud, clattering outbursts of Clapper Rails are a signature sound of saltmarshes and mangroves in eastern North America and the Caribbean. It’s much rarer to catch sight of these large, chestnut-and-gray rails, as these shy birds emerge only briefly onto mudflats and quickly vanish again into the dense marsh grasses. King Rails can be very similar, but are typically more brightly colored and favor freshwater marshes.
