Explain your response as it relates to the specific ecosystem. Possibly on the west coast, the marshland habitat is being compromised in several ways. The bays that it uses in California are being drained and polluted. Humans are moving into the area insuring an unsettling habitat for these fairly reclusive birds. These are its breeding areas. Without an area to raise its young its population will continue to decline. Finally, it is so closely related to the king Rail that they freely interbreed and produce viable young. They are considered the same species by some scientists. On the East coast they have a little more leeway. Their breeding grounds aren't being impinged upon so greatly. They have a lot more area to survive. Both coast's rails occupy coastal grounds from the North through the South American shorelines including the islands in between.
