Wattled cranes are generally silent, and when they do call, the voice is high-pitched and somewhat squeaky. Siberian cranes have soft flute-like calls that are simpler in structure than the call of other Grus species. Sarus have the loudest and shrillest calls of cranes, and brolgas have the lowest calls. As its name suggests, the whooping crane has a penetrating call that carries for great distances over the wetlands. The voice of the Gruinae cranes is modified by coiling of the trachea in the sternum.
Sandhills and Eurasian, and to a lesser extent black-necked and hooded, apply iron-rich mud to their backs that stains the feathers a reddish-brown color. With the neck lowered while incubating, a painted crane blends with the pile of mud and dead wetland vegetation that constitutes the nest. Undoubtedly, they are much less obvious to predators than are white cranes. In contrast to the wattled and Grus, the blue and demoiselle cranes often lay their eggs on the ground in grasslands and do not build a nest.
