“Cranes dance to attract a mate!”

Cranes are a collection of tall bird species with long legs. There are 15 different species of these birds in the world, usually having brown, white or gray coloring. Different species of these birds live across every continent except South America and Antarctica, typically breeding in the north and flying south to warmer climates for the winter. America’s largest bird is a whooping crane, standing five feet tall and spreading wings up to seven feet. They are known for being highly social birds that perform elaborate dances to attract lifelong mates.

5 Crane Facts

  • There are 15 species of cranes in the world today
  • The birds fly with necks and legs outstretched
  • These birds are omnivores
  • Their flight takes them as high as 26,000 feet off the ground

Scientific Name

Red-Crowned Crane

Cranes were named for their characteristic hoarse cry; they can be found across five continents


Fifteen different species of these birds live across five continents. All of these magnificent birds belong to the class Aves, order Gruiformes, superfamily Gruoidea, and family Gruidae. The name crane is of Germanic origin, the words Kran in German and kraan in Dutch. At the same time in history, in the 16th century, the world developed through Middle English as crane. The word means to “cry hoarsely.” Now, the word is also used to describe someone stretching out their neck or limbs like the bird, as in, “He craned his neck.”


Types of Crane birds

Asian and Africa are home to the greatest varieties of crane species

As part of the order Gruiformes, cranes are also related to rails also known as Rallidae, finfoots or Heliornithidae and limpkins or Psophiidae. Scientists believe that the existing genera of cranes including Antigone, Balearica, Grus, and Leucogeranus, emerged on the evolutionary scene about 20 million years ago during the early part of the Miocene (which itself lasted between 5.33 – 23 million years ago).

Asia is home to the largest number of species – eight. Next in line is Africa, which is home to five species, two of which are somewhat arboreal, while North America is home to two – as is Australia.

Subspecies of these birds and their warm-season habitats include:

  • Common crane:  This avian is capable of measuring 51 inches in length and weighing over 13 lbs. It has a wingspan of about 8 feet and is the only species found in Europe.
  • Red-crowned crane: Known for the patch of red skin on their crowns, these birds are capable of growing to 5 feet 2 inches in height and weighing up to 23 lbs. They can be found in east Asia.
  • Sandhill crane: This species has a maximum height of 4 feet 6 inches and an average weight of 10 lbs. It is generally gray and can be found in Siberia and North America.
  • Sarus crane: Its claim to fame is its status as the tallest flying bird with a maximum height of 5 feet 11 inches. Found in India, Southern Asia, and Australia, it is capable of weighing up to 26 lbs.
  • Whooping crane: This species is capable of reaching a height of 5 feet 3 inches and weighing 19 lbs. Its wingspan is about 7 feet 7 inches and it is native to North America.
  • Demoiselle Crane of northwest Africa, Ukraine and southern Russia, central and eastern Asia
  • Blue Crane of South Africa and Namibia
  • Wattled Crane of Ethiopia, South Africa, and southern Africa
  • Siberian Crane of western Siberia and northeastern Siberia

Appearance & Behavior

Sarus crane

The sarus crane is the longest flying bird in the world.

Thes birds are the world’s tallest flying birds that range in size from only 35 inches long to 69 inches long. The Demoiselle – is the smallest and Sarus Crane is the longest. But the heaviest one is the Red-Crowned Japanese Crane, which weighs up to 26 pounds before flying south for the winter or north for summer. The birds all have long legs, long necks, large wings, and streamlined bodies. They vary in wingspan, with their wings having a rounded appearance. Males and females look the same, but males are a bit larger.

The feathers and markings vary according to their habitat. Open wetland birds typically feature more white in their coloration than species from forests or small wetlands. The birds living in the forest or small wetland habitats feature more grey. The white birds generally grow larger, too. Smaller forest birds with their darker coloring can blend into their environment better while nesting. Of these forest dwellers, Sandhill – and common cranes apply mud to their feathers to better hide from predators.

All of these bird types except the Blue and Demoiselle cranes feature bare skin on their faces. They use this skin to communicate with other birds by expanding and relaxing their muscles. This activity also changes the color of their face. Blue, Wattled, and Demoiselle cranes can move the feathers on their head to signal their flock, too.

These birds have special throat features that help them communicate, too. Some have a shorter windpipe that only presses gently upon a bone in their chest. Others have a longer windpipe that presses deeply into the bone in their chest. Still other species of cranes have fused bones of the windpipe and chest that give more power to their calls. In this last group, the calls can travel for as far as several miles. 

These birds’ calls include a large vocabulary. They start learning these special calls that work like human language from the time they hatch. Their first calls beg for food from parents and signal that they are content or need parents’ attention. They soon learn alarm calls and calls signal that they are about to launch into flight. They recognize each other by their calls and even form duets.

During breeding season, these birds become very territorial and stay on their own territory full time. During non-breeding season, many species of these birds form large flocks, socialize, engage with each other and feed together. The birds that eat mostly plants feed in flocks, but the ones eating meat feed in family groups and rejoin the flock for rest or travel. It is important for these birds to stick together in groups to keep them safe when resting, protect their young and socialize.

Cranes can be found on every continent except Antarctica and South America

These birds live on all continents except South America and Antarctica. Africa and East Asia have the most variety for these birds living in one region. Africa has eight species, whereas East Asia has six during its peak season. With 15 different species among the broader family of cranes, each type has its own preferred habitat.

Most of them need wetlands for their survival, as well as broad, open areas. The majority also nest in the shallows of wetlands, while some nest there but move their chicks to grassy lands for daytime feeding. Only the two types of African crowned cranes do not roost in wetlands. Instead, they roost in trees.

Not all of these birds migrate with changing seasons. Some are sedentary, which means they stay in one region throughout the year. Of those that fly to warmer weather for winter, many travel thousands of miles to their breeding habitats.

These birds are omnivores. They can eat both animals and plants. Preferred foods on land include seeds, nuts, acorns, leaves, berries, and fruit. They also eat insects, birds, small reptiles, small mammals, snails, and worms. While living in wetlands, they feed on roots, tubers, rhizomes, snails, frogs, and small fish. Their diet is highly adaptable according to their location, time of year, and food availability. However, the birds with shorter beaks prefer dry upland foods and the ones with longer bills prefer wetland foods.

The birds feeding in wetlands dig for tubers and rhizomes. This requires them to stay in one place for a long period of time as they dig and expand a hole searching for these foods. They also lower their heads and move very slowly forward with their bills probing for insects and small animals.

To reduce competition, two species living near each other adopt their own habitats. This prevents overfeeding on available foods and ensures all have access to nutrition. For example, in China, Siberian cranes feed in shallow water and mudflats while their neighboring White Naped cranes feed on the edges of the wetlands. At the same time, Hooded cranes in this same area feed on meadows and agricultural fields, sharing the fields with common Eurasian cranes.

Predators & Threats

Eagles are some of the few predators capable of targeting cranes


Because adult birds are so large, few predators challenge them in their natural habitats. But some predators do exist and include other large birds of prey, such as owls and eagles. They also include foxes and wildcats. Chicks are highly vulnerable to these ground-based predators.

People take over their habitat and threaten these birds through urbanization. This affects population numbers by driving cranes away from their breeding, roosting, nesting, and feeding grounds.

Reproduction, Babies, & Lifespan

These birds are monogamous. This means they have a lifelong mate. They typically find this mate during their second or third year of life. But they do not successfully breed for several years. To attract a mate, young birds perform a mating dance. They flap their wings, bow, jump, and throw small sticks or plants.

During their first breeding attempts they often fail. Sometimes this period of failure leads to a “divorce” of the birds to find new mates. As long as they breed successfully, a male and female will stay together in their lifelong pairing.

Scientists studied Sandhill cranes in Florida. Of these 22 pairs, seven couples stayed together for 11 years. Of the 15 that did not stay together, just over half of the relationships ended because of one of the birds’ death. About 18 percent of the birds divorced and scientists could not track 29 percent of the pairs.

These birds breed according to the individual breeding season of their species. The season depends on local climate and conditions. Migrating birds breed immediately upon arriving in their summer habitat from late spring to early summer. Tropical birds typically prefer to breed during wet or monsoon seasons.

The eggs hatch about a month after laying. When the chicks hatch, their parents feed them until the babies can fly away from the nest. This is typically after two months. Young birds can reproduce at three to five years of age.

Wild birds typically live for 20 to 30 years. In captivity, a Siberian crane lived for 83 years.
