Sinopsis

Reelfoot Lake in western Tennessee, near the Mississippi River, was created by the New Madrid earthquakes on December 16, 1811, and February 7, 1812. The shallow lake that resulted is ideal habitat for the Great Blue Heron. Shallow water is important, because the birds' method of hunting for food involves standing motionless in water and spearing fish, frogs, and other animals that happen to come its way. Trees like the bald cypress, which grow in shallow water, are also important to these birds, since herons build their nests in the trees over water. Usually, several pairs of birds build nests in die same area. Changes in water level, fertilizer, and pesticide run-off from agricultural land, and use of die heron habitat for recreational purposes all have an influence on the success of the Great Blue Heron. These interacting factors illustrate the theme of this text: Interrelationships.
