About These Birds
Black Rail
Black Rail (Laterallus jamaicensis) is a tiny 10–15 cm, secretive rail of North and South America. Very dark charcoal-black with reddish-brown nape and white spotting on back; red eye. Breeds in coastal salt marshes and freshwater marshes; winters further south. Declining sharply due to marsh loss and sea-level rise.
White Swamphen
White Swamphen (Porphyrio albus) is an extinct all-white swamphen formerly endemic to Lord Howe Island, Australia. Known from specimens collected around 1790 and early drawings; had reduced wings indicating flightlessness or near-flightlessness. Extirpated by hunting after European discovery. Related to Australasian Swamphen.
