Cranes are a family of large, long-legged and long-necked birds in the order Gruiformes. There are 15 species of cranes, which are found on every continent except South America and Antarctica. Cranes are known for their graceful and elegant appearance, and they are often associated with long-distance migration and wetland habitats.
Cranes are generally large birds, ranging in size from the demoiselle crane (Anthropoides virgo), which is about 90 cm (35 inches) tall and has a wingspan of about 170 cm (67 inches), to the Sarus crane (Grus antigone), which is up to 1.8 meters (6 feet) tall and has a wingspan of up to 2.5 meters (8 feet). Cranes have long, thin legs and long, thin necks, and they are often found standing on one leg.
Cranes are omnivorous, feeding on a variety of plant and animal matter including seeds, grains, insects, worms, and small vertebrates. They are known for their elaborate courtship displays, which often involve dancing and vocalizations. Cranes are also known for their long-distance migrations, which can take them thousands of kilometers between their breeding and non-breeding habitats.
Cranes are found in a variety of habitats including wetlands, grasslands, and forests. Many species of cranes are considered to be at risk of extinction due to habitat loss, hunting, and other human activities. Conservation efforts have been successful in increasing the populations of some crane species, but many species are still considered to be at risk.
