Differences between Crane and Eagle

Crane Crane
Eagle Eagle

Crane and Eagle are two classes of birds that belong to the Gruidae and Accipitridae families respectively.

Cranes are graceful tall birds with long neck, long legs, and long bill. They are ancient birds. Their fossil, assessed to be 2.5 million years old, have been found in Florida. Cranes are wading birds that resemble Herons. They are generally white, gray, or brown in color. Their forehead is a bright red, while their bill is large and pointed. The Crane family consists of 15 species.

Eagles are one of the largest and powerful birds on the planet. They are revered as mythological birds in several cultures of the world. There are about 60 species of Eagles, prominent among them being Harrier Eagles, Hawk Eagles, Martial Eagles, American Bald Eagle, and Sea Eagles. Eagles are at the top of the food chain. They have splendid eye sight and can see as far as three kilometres beyond. Their heads are fully feathered and usually white. The birds have wide wings, strong feet, and curved nails. Their plumage is usually brown in color, while their hooked beaks are orange. Eagles are known for their fearlessness and strength.

Where are Crane and Eagle found?

Cranes prefer grasslands, wetlands, marshes, canals, ponds, and shallow waters. Nevertheless, they can also be found near agricultural fields. They are not intimidated by humans. Cranes are a common sight across the world, except Antarctica and South America.

Eagles live near waterbodies like lakes, rivers, and seas. They prefer to perch, roost, and nest on tall trees. Most Eagle species are found in Europe, Asia, and Africa. About 11 of them exist in North and South America, while a couple of them are from Australia.

What do Crane and Eagle eat?

Cranes are omnivores. They mostly eat fish, rodents, and insects. When they are close to wetlands, they eat worms, snails, and tiny invertebrates. In dry places, they eat grains, nuts, leaves, seeds, berries, small reptiles, and insects.

Eagles are largely carnivores. Their diet depends on the species and geography. They generally eat mammals and birds. The ones living near water bodies also prey on aquatic animals, gulls, and seabirds. Eagles are fierce hunters but they also steal food from other Eagles and birds. However, they rarely eat dead meat.

  • Both Crane and Eagle eat Squirrels.
  • Gophers are commonly eaten by Crane, but not by all Eagle.
  • Crane do not eat Baby Ducks while Eagle eat Baby Ducks.
  • Mice are eaten by both Crane and Eagle.

Size of Crane and Eagle?

When it comes to size, Cranes are thought to be the tallest flying birds in the world. They generally grow up to four to five feet tall. They also have a wide wingspan of about nine feet. The Whooping Crane is the tallest bird in the USA with a height of five feet. The Sarus Crane is the tallest flying bird in the world at 5.12 feet.. Eagle is a well-built bird. Its size depends on the species. The male is generally three feet tall with a wingspan of 6.6 feet. The female Eagles are larger with a height of 3.5 feet and wingspan of eight feet. The largest of all Eagle species is the Giant Philippine Eagle.

The average weight of Cranes is 6.6-13.4 pounds. The Red Crowned crane is considered to be the heaviest of all Crane species at 20 pounds. while The weight of Eagles varies according to their species. The average weight of male Eagles is six to nine pounds, while it is 10-15 pounds for females. Steller’s Sea Eagle is the heaviest species with a weight of 14.75 pounds.

Where do Crane and Eagle nest?

Cranes generally build their nests in shallow freshwater and marshy areas. The nests are made of weeds, grass, and plant material. However, Crowned Cranes build their nest in low trees, while Sandhill Cranes construct them in the Arctic. Cranes lay two eggs at a time, with the incubation period being 28-30 days. Both male and female partners engage in rearing the young ones, which live with them until the following breeding season.

Eagles build huge nests on top of trees by weaving sticks and branches. Both male and female collaborate to construct the nests besides taking turns to incubate the eggs. It takes about 35 days for the eggs to hatch. The little ones fledge when they are 10-12 weeks old.

How long do Crane and Eagle live?

The average lifespan of Cranes is 20-30 years. Mortality is high among younger Cranes of less than three years due to predation. A Siberian Crane had lived up to the age of 62 at the National Zoological Park, Smithsonian Institute, USA. A Siberian Crane lived longer – it was 83 years old when it died.

The lifespan of Eagles differs based on their species. On an average it is 14-35 years in the wild. The Eagle that lived the longest in the wild was 31 years and eight months old. It lived in North America. The longest-lived Eagle in captivity was in Europe. It lived for 46 years.

Are Crane or Eagle migratory birds?

Some species of Cranes migrate long distances, while some of them are non-migratory. Some Siberian Cranes fly from western Siberia to south India, while Common Cranes migrate across Europe and Asia. Some species also migrate to northeast India. Sandhill Cranes are considered to migrate the longest distance, travelling between Siberia and Mexico every year. Other species like Demoiselle Cranes, Hooded and Red Crowned Cranes also migrate long distances to countries like China, Russia, and Japan each year.

Not all Eagles are migratory. If the weather, water, and food supply are favorable, they remain in the same territory. They migrate if food is in short supply or if winters become too cold for them. The place they migrate to depends on wind currents. Bald Eagles from Alaska usually migrate southward during August-January, while the ones near the Great Lake and in the Canadian region travel eastward. Eagles from Africa move around the Red Sea, passing by Suez, Egypt, and Israel. The ones in Europe are likely to move south towards sub-Saharan Africa. Within Asia, Eagles migrate from their breeding grounds during winter to places in China, Korea, Japan, and India.

Do Crane and Eagle fly in flocks?

A group of Cranes is called a sedge. Cranes, especially the Sandhill species, form large flocks. They are gregarious birds that congregate together during migration and winters. However, they prefer solitude and live in pairs during the breeding season.

A flock of Eagles is known as convocation. Eagles are social and sometimes roost in groups. However, they are known to fly and hunt solitarily. At times when they have to maintain altitude and stay within the thermal column, they fly in circles. Bald Eagles are observed to fly in groups during migration.

Are Crane or Eagle protected?

In the USA, Sandhill and Whooping Cranes are protected under the Migratory Bird Treaty Act. Cranes are protected in the UK, where they had become extinct about 400 years ago. The Common Crane or Grus Grus is a protected species in the European Union. The Great Sarus Crane is protected in India along with efforts of conservation of other migratory species.

Eagles are protected across the world. Killing, hunting, or capturing them is a punishable offence. It is also illegal to destroy their nests or trade the birds.

Are Crane or Eagle endangered?

Cranes were widespread in the world. However, their population is gradually declining, especially of some species. This can be attributed to loss of wetlands and marshes, rise in deforestation and urbanization, hunting of birds for meat and feathers, inadequate regulations for conservation, collision of birds with electric power lines, and fatigue and death of birds during migration. The Siberian Crane is the most endangered species. Whooping Crane, Blue Crane, and Hooded Crane are other species that are facing the danger of extinction.

All Eagle species are not endangered. Bald Eagles were once endangered in the USA, however conservation laws have helped a recovery in their population and they are no longer endangered. Bald Eagles population however faces threat from hunting, trapping, loss of habitat, and use of pesticides. The Great Philippine Eagles are an endangered species with only about 400 of them remaining.

Can Crane and Eagle fly?

Cranes are considered to be the tallest flying birds in the world. They fly with their head and neck stretched out and legs trailing behind. During migration, they fly 200 miles in a day using the warm air to achieve height and drift. These birds can fly at an altitude of 16,000-26,000 feet above sea level. Demoiselle Cranes migrate over the Himalayas at an altitude of 26,000 feet to enter India. The Siberian Crane flies almost 10,000 miles in a year for migration.

Eagles are remarkable flyers. They have large and widespread wings. The bird uses thermals to soar high and fly without flapping its wings. Eagles fly at a speed of 20-30 miles an hour. They are capable of flying up to 125 miles without stopping. During migration, Bald Eagles travel about 225 miles in a day.

Can Crane and Eagle swim?

Cranes cannot swim as they do not have webbed feet. The chicks however swim and follow their parents in the marshes. Adult Cranes avoid deep waters and generally live near shallow waters where they can wade through with their long legs.

Eagles can swim, although they are not regular swimmers. When an Eagle captures a prey in water and it is too heavy to carry, or it is unable to fly carrying it, it swims by using its feathers like oars. However, it has to get out of water quickly as the feathers become wet and heavy.

Mating patterns among Crane and Eagle

Cranes generally start breeding once they are three to five years old. They breed once a year during the breeding season. They perform elaborate dances involving sophisticated footwork during courtship. They also perform unison calling, which according to scientists strengthens the bond between the male and female besides defend territory. Both partners engage in picking up straws and plant material to build the nest. They even use the same nest for multiple years.

Eagles reach sexual maturity at the age of four or five years, when their head and tail become white. In the breeding season, Eagles perform many mating rituals. The prominent among them is the Cartwheel Courtship Flight or the Death Spiral, where two Eagles fly high, clasp each other’s talons and spin down while challenging one another to let go of the grasp. This is a display of their strength and arrogance. The male and female partners build the nest together. The female generally lays one to three eggs at a time. Both partners take turns to incubate the eggs.

When is the mating season for Crane and Eagle ?

The breeding season depends on geography and species. In the case of migratory species, it is usually during the summer. In the case of other species, the breeding season corresponds with the monsoon.

There is generally no particular mating season. Eagles mate throughout the year. However, in the case of Eagles that migrate, mating takes place as soon as the partners return to their nesting place.

Do Crane and Eagle mate for life?

Most cranes mate for life. They are monogamous for life or until one of them dies. The partners may break up and find new ones if breeding attempts fail.

Eagles mate for life. The partners are faithful to each other and stay monogamous until one of them dies.

How do Crane and Eagle sleep?

Cranes sleep at night, usually with one or both legs in water and head bent down. They sometimes also sleep while standing on the ground. Cranes however sleep closer to their nests during the breeding season in order to protect the eggs and little ones from predators.

Eagles sleep either while standing or laying down. If they have to sleep while standing, there is a locking mechanism in their feet that allows them to stay in one position. In winters, Eagles roost in communities and on large trees to maintain body heat. During the breeding season, they sleep closer to the nest to keep guard.

Can Crane and Eagle be eaten?

Cranes are edible and are widely consumed by humans since ancient times. It is recorded in history that the Christmas feast hosted by King Henry II in 1251 involved the meat of more than one hundred cranes. Some countries still allow hunting and consumption of Cranes.

People from different cultures are known to have consumed Eagles. The practice still exists among some tribes although the bird is protected and killing it for food is prohibited. In the USA, a few hundreds of tribes are allowed to request for a permit to kill Eagles.

Can you hunt Crane or Eagle?

Hunting Cranes is allowed in several states of the USA. It is also allowed in Canada with the acquisition of a permit. However, hunting the birds is not allowed in some countries like India. Unregulated hunting and easy to obtain hunting permits allow people to kill Cranes for their meat and feather.

Hunting Eagles for falconry was a common practice in ancient times. However, modern conservation and protection laws do not allow hunting and killing of the birds.

Can you feed Crane or Eagle?

Feeding wild animals and birds in public places is not permitted in places like USA, Singapore, and Dubai. In captivity, Cranes are fed worms, small fish, lizards, and insects besides grains, berries, and fruits.

Feeding birds in public places is discouraged in many countries like the USA, Singapore, and Dubai. In captivity, Eagles are generally fed with rats, rabbits, chicken, and meat.
