Generally, cranes are large birds, ranging from a length of 90 cm to 150 cm. Anthropoides virgo is known to be the smallest crane, with an average adult length of 90 cm. Cranes are recognized for their long necks and legs, their streamlined bodies, and long rounded wings. Demoiselle cranes can be distinguished by specific physical features and other unique characteristics. Most cranes have bare, red skin patches on their heads, however, demoiselles have a completely feathered head with a white line that extends from the corner of their red eye, to the back of their head. During display, they can elongate these feathers on the sides of their head. With feathery gray areas ranging from the crown to the nape, the bird has a dark underside, with black legs and toes. The main distinguishing features of A. virgo are their short toes and bills. Adapting to run in the grassland habitat, the toes have evolved to be shorter, as the shorter bills can forge for food more efficiently in upland areas. The length and positioning of the trachea can also distinguish a demoiselle crane from other cranes; Demoiselles have a trachea that makes a slight indentation on the sternum.
After hatching, demoiselle chicks are silver gray, and as they develop into a juvenile demoiselle, they become predominately Grey at the time of fledging. This color assists in camouflaging the bird. Once developing into an adult, they appear as previously described above. An important fact about A. virgo is that the male and female are mono morphic - identical in their external features; however, the males are usually larger.
