Quick Answer
The Greater Crane (Grus grus) is larger and has a more extensive range than the Lesser Crane (Grus virgo), with a distinctive red crown on its head and a more robust build. The Lesser Crane is generally smaller and has a grey crown. These differences distinguish the two species.
Physical Characteristics
The Greater Crane is the larger of the two species, reaching heights of up to 1.7 meters (5.6 feet) and weighing between 4-6 kilograms (8.8-13.2 pounds). In contrast, the Lesser Crane stands at approximately 1.4 meters (4.6 feet) tall and weighs between 2.5-4 kilograms (5.5-8.8 pounds). The Greater Crane also has a greater wingspan, typically between 2.3 and 2.5 meters (7.5-8.2 feet), compared to the Lesser Crane’s wingspan of approximately 2 meters (6.6 feet).
Habitat and Distribution
The Greater Crane is found throughout Europe, Asia, and parts of Africa, while the Lesser Crane has a more restricted range, primarily inhabiting the steppes and grasslands of Eastern Europe, Russia, and parts of Western Asia. The Greater Crane is a migratory species, traveling from its breeding grounds in the Arctic tundra to its wintering grounds in Africa and southern Europe, whereas the Lesser Crane is a partial migrant, with some populations remaining in their breeding grounds year-round.
Diet and Behavior
Both cranes are omnivorous, feeding on a variety of plants, insects, and small animals. However, the Greater Crane tends to feed on more aquatic plants and insects, whereas the Lesser Crane feeds on a wider range of terrestrial plants and invertebrates. In terms of behavior, the Greater Crane is known for its elaborate courtship displays, which involve complex dancing and calling rituals, whereas the Lesser Crane’s courtship behavior is more subdued and less well-documented.
