The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
The King Rail is the freshwater cousin of the saltwater-loving Clapper Rail. King Rails are at home anywhere there is a large cattail marsh. The biggest existing threat to King Rails is probably the draining of marshes across its breeding range, which extends across much of the eastern U.S. and barely into Ontario. Adding to this threat, Audubon's climate model projects an 87 percent loss of current winter range by 2080, dispersing suitable wintering climate space across the interior of the eastern US. While birds in the U.S. may be forced northward, it remains to be seen how birds currently wintering throughout coastal Mexico and Cuba, outside of the model's analysis, may respond.
