Differences between Crane and Seagull

Crane and Seagull are two classes of birds that belong to the Gruidae and Laridae 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.

Seagull is the vernacular form for the bird Gull. Known to be clever, these birds are mostly large in size with grey or white plumage. They have big black marks on their head and wings. Their beaks are usually yellow in color with a red spot and a hook at the tip. Bigger Seagulls have pink legs, while the smaller ones have red or black legs. The birds have webbed feet. There are over 40 species of Gulls across the world.

Where are Crane and Seagull 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.

Gulls are water birds. They are typically found near coasts, especially during summers. However, they have become common even at inland waterways like rivers, reservoirs, and lakes. They can adapt to any region as long as there are food sources there. Consequently, Gulls are visible even inside cities and towns. Gulls exist everywhere in the world. They have been found even near Antarctica and the Arctic.

What do Crane and Seagull 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.

The natural diet of Gulls includes fish and other aquatic animals. Besides, it includes land animals like insects, worms, mice, and reptiles. However, Gulls are scavenging birds and can eat just about anything. They have been observed eating fruits, vegetables, and even chips, bread, and spaghetti. Gulls are one of the very few birds that can drink both salt and fresh water. The salt ducts and glands in their beaks act as desalination filters and help the birds to pass up excess salt.

• Both Crane and Seagull eat Fish.
• Both Crane and Seagull eat Frogs.
• Both Crane and Seagull eat Lizards.
• Both Crane and Seagull eat Snakes.

• Mice are eaten by both Crane and Seagull.

Size of Crane and Seagull?

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.. The size of Gulls depends on the species. The smaller ones are generally about one foot long, while the larger ones could measure about 1.5 feet. The average wingspan of the birds is 2.9-3.3 feet.

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 Gulls varies drastically for different species. The Little Gull weighs just about 4.2 ounces. On the other hand, the Great Black-beaked Gull weighs 3.8 pounds.

Where do Crane and Seagull 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.

Gulls build their nests in their habitats. It could be at cliffs, coasts, islands, trees, and rooftops as long as they are safe, have food sources nearby, and inaccessible to predators. The nests are built using grass, twigs, and plant material. The eggs take about three weeks to hatch. The young ones are active and fledge when they are five to six weeks old.

How long do Crane and Seagull 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.

Gulls have a short lifespan. They live for 8-20 years in the wild. The longest-lived Gull was from Denmark and lived for 33 years and eight months.

Are Crane or Seagull 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.

Gulls are generally migratory. They move from northern hemispheres during winter to regions where there are abundant food sources. The birds from Canada and North America move to the tip of South America or parts of USA where the temperature is not freezing. The Black-Headed Gull migrates from UK to southern Europe, the Middle East, and Africa. Similarly, Gulls migrate from China to Thailand, and from Russia and Siberia to the Indian subcontinent. Some Gulls living on French and Spanish coasts and other warmer regions do not migrate. Additionally, Gulls that have settled in cities where they get easy access to food from human refuse, safe nesting places in rooftops, and warmth from buildings may not migrate.

Do Crane and Seagull 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 Gulls is called a squabble, screech, scavenging, or colony. Gulls live in groups, consisting of a few birds or even up to a thousand. They unite to drive away predators. Besides, they adopt different body language and sounds to communicate with each other. Gulls stay with their flocks almost throughout the year.

Are Crane or Seagull 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.

Seagulls, their nests, and eggs are protected under various laws across the world. Harming these in any way is considered a punishable offence.

Are Crane or Seagull 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.

Some species of Gulls are endangered. According to the International Union for Conservation of Nature, the Chinese Black-Headed Gull and Relict Gull are vulnerable to extinction, while Heermann’s Gull and White-Eyed Gull are threatened. The population of Glaucous-winged Gull has declined by 50 percent in Georgia Basin, while the numbers of Gulls in Canada and the UK are also falling drastically. This has been attributed to loss of habitat, pollutants, and poor food quality.

Can Crane and Seagull 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.

Gulls are highly skilled in flying. They have expert control on wind and thermals, and can execute complex manoeuvres. They can fly at speeds of up to 28 miles per hour. The birds fly extremely long distances during migration. Gulls are capable of flying during the night as well. When there are changes in air pressure due to an oncoming storm or earthquake, Gulls gather in circles to regulate their focus and balance.

Can Crane and Seagull 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.

Gulls are also adept swimmers. They can live comfortably both on land and water. They have webbed feet and can swim well both in sea and fresh waters. However, they do not swim too far in the seas. They usually swim in search of food.

Mating patterns among Crane and Seagull

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.

Gulls start mating when they are about four years old. The heads of the Gulls are in pure white, black, brown, or gray color in the breeding season. They are known to mate both inland and on coasts, however copulation occurs on land at breeding sites. The courtship involves complex dances, rituals, and articulations. The Gulls mate until the female can lay an egg. They build their nests in colonies. Both male and female partners incubate the eggs for about 30 days.

When is the mating season for Crane and Seagull ?

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 breeding season for Gulls is usually March-July every year. The birds gather at breeding colonies few weeks before the onset of the season.

Do Crane and Seagull 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.

Gulls are monogamous and stay with the same partner throughout their lives. They even return to the same breeding site every time.

How do Crane and Seagull 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.

Gulls generally sleep during the night. However, they are scavengers and are known to be awake and flying even in the night. In natural habitats, they sleep on beaches, rivers, and lakes. The city-dwellers sleep in parks and rooftops. Gulls usually roost in groups to stay safe from predators.

Can Crane and Seagull 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.

Gulls were consumed in the past by Inuit, Alaskan, Hare, and other cultures for survival. The meat of the birds is not considered appetizing. Further, it is illegal to hunt and eat Gulls under modern laws.

Can you hunt Crane or Seagull?

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.

Cultures in the northern hemisphere have hunted Seagulls in large numbers in bygone times. Some cultures have killed the birds for food. However, Gulls are not permitted to be hunted under existing laws.

Can you feed Crane or Seagull?

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.

It is illegal to feed Gulls in public in some countries like the USA and Singapore. In countries like the UK, France, and India where feeding Gulls is allowed, the governments request the people to not feed processed food to the birds as it will harm their health. Gulls are scavengers, but it is advised to feed them healthy food like fish, worms, mice, and meat.
