Differences between Crane and Egret
Crane and Egret are two classes of birds that belong to the Gruidae and Ardeidae 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.
Egrets are birds that symbolise purity and strength. They belong to the species of Herons. These birds have white plumage that were used in earlier times for dress and trade. Egrets differ from other species of Herons by their mating displays and the pure white plumes they develop in the breeding season.
Where are Crane and Egret 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.
Egrets live close to wetlands, be it fresh or salt. You can find them near seas, rivers, marshes, ponds, and thick forests. They were originally found in Europe, Asia, and Africa but have later spread across the world. As they cannot survive colder weather, they are not distributed in Antarctica and the Arctic.
What do Crane and Egret 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.
Egrets are carnivores that source their feeds generally from water systems. So, their diet mostly includes fish, water insects, frogs, snakes, and crustaceans. However, Egrets sometimes also hunt on land and eat insects, grasshoppers, and rodents.

Size of Crane and Egret?
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.. Egrets are smaller than Herons. They are a little less than three feet tall and have wings that measure 1.3-1.7 metres.
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 An adult Egret usually weighs 1.1-3.3 pounds.
Where do Crane and Egret 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.
Egrets generally build large and messy nests in their colonies that even consist of birds of other species. The nests are usually constructed on shrubs or lowly trees, typically 10-40 feet from the ground. It is mostly the male egret that establishes the nesting area by creating a nest platform. Both the male and female egrets incubate the eggs for a period of around 24 days.
How long do Crane and Egret 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.
Lifespan of an Egret is up to 15 years in the wild. The younger ones could face high mortality due to climate, migration, predators, and siblicide. The oldest Great Egret lived for almost 23 years in the state of Ohio.
Are Crane or Egret 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.
Egrets become residents in warmer locations. However, in regions where they cannot withstand the cold, they tend to migrate after the breeding season. Migration usually happens from Europe to Africa and south Asia and from northern parts of the USA to central and southern America.
Do Crane and Egret 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 group of Egrets is known by different names, such as colony, siege, skewer, wedge, and congregation. Egrets are sociable and hunt in flocks. But they can also remain isolated. They generally gather during sunsets and roost in colonies.
Are Crane or Egret 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.
Governments across the world have taken measures to protect Egrets under wildlife conservation and migratory bird laws. Egrets are protected in various countries like the USA, UK, China, Taiwan, China, Russia, India, and France.
Are Crane or Egret 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.
The population of Egrets dwindled to near extinction in the 19th century owing to devious hunting of the birds for their plumes. However, introduction of protection and conservation laws have helped in resurgence of their population. Egrets can now be commonly found in wetlands and coasts across the world. They are not an endangered species.
Can Crane and Egret 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.
Egrets start flying when they are six to seven weeks old. They are dynamic flyers with an ability to cover 25 miles in an hour. They tuck their neck in and hold their legs freely in flight. They are capable of flying long distances during migration.
Can Crane and Egret 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.
Egrets are generally wading birds. They rarely swim to catch their preys. Further, they have non-webbed feet that makes swimming difficult for them.
Mating patterns among Crane and Egret
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.
Egrets acquire heightened beauty during the breeding season – the reason for which bird watchers yearn to catch a glimpse of them during this time. The birds start mating when they are two or three years old. Each breeding season of the year, the male egret selects a nesting area where it builds a nest platform. It then displays its special long white plumes to find a mate for courtship. Egrets generally breed in their colonies and seldom in solitary pairs.
When is the mating season for Crane and Egret ?
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.
The mating season for Egrets is usually October-December in the southern hemisphere and March-May in the northern hemisphere. They breed only once a year.
Do Crane and Egret 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.
Egrets are monogamous during each breeding season. However, they may not stay with the same partner every year. They are known to have multiple partners in their lifetime.
How do Crane and Egret 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.
Egrets sleep at night while standing on one foot in water to sense vibrations from predators. They keep their heads retracted under a wing. They generally roost in flocks to stay safe from attacks.
Can Crane and Egret 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.
Egrets used to be eaten in earlier times in some parts of Africa. However, they no longer can be hunted for their meat. It is illegal and will invite hefty fines.
Can you hunt Crane or Egret?
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.
Egrets were hunted ruthlessly until late 19th century for their plumes. This led to their near extinction. Nevertheless, new anti-hunting, conservation, and migratory laws adopted across the world have saved the species. Egrets are widespread and a common sight now.
Can you feed Crane or Egret?
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 wild animals and birds in public places is not permitted in places like USA, Singapore, and Dubai. In captivity, Egrets can be fed with fish, eggs, insects, earthworms, and meat.
