Most have elaborate and noisy courting displays or "dances". While folklore often states that cranes mate for life, recent scientific research indicates that these birds do change mates over the course of their lifetimes (Hayes 2005), which may last several decades. Cranes construct platform nests in shallow water, and typically lay two eggs at a time. Both parents help to rear the young, which remain with them until the next breeding season[1].
Some species or populations of cranes migrate over long distances; others do not migrate at all. Cranes are gregarious, forming large flocks where their numbers are sufficient.
