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.
There are people who’ve been birding for decades and have never laid eyes on a Yellow Rail. This tiny, straw-colored bird found in dense, marshy grasslands and rice fields is seldom detected, especially in the winter when it is silent. Audubon's climate model forecasts a 100 percent loss of current winter range by 2080. Perhaps most important for the survival of this species is preventing the large-scale draining of marshland. That practice caused the extinction of a subspecies of Yellow Rail in central Mexico, which no longer hosts the species at all.
