Crows are particularly known for their cleverness. They have great discerning abilities and have excellent self-control. They can make their own tools, solve problems, remember faces, mimic sounds, and prank other animals. They are also trainable. There are around 40 species of crows across the world.
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 Crow and Seagull found?
The natural habitat of Crows include grasslands, forests, mountains, agricultural regions, and deserts. They like locations where there are trees. However, these birds are highly adaptable and exist everywhere. They are common sight even in big cities. Crows can be found in all parts of the world. The exceptions are South America and Antarctica.
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 Crow and Seagull eat?
Crows are omnivores. They are both predators and scavengers. They can eat anything. They eat rodents, reptiles, small mammals, worms, insects, and eggs besides grains, fruits, nuts, and human food.
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.

Size of Crow and Seagull?
When it comes to size, The size of crows varies for different species. Jackdaw Crow is the smallest with a length of 13-15 inches and wingspan of 27 inches. Thick-billed Raven is the largest among the species. It is 28 inches long with a wingspan of 45 inches.. 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.
Thick-billed Raven is the largest among crow species. It weighs 2.5-3.3 pounds. On the other hand, the weight of Jackdaw Crow, the smallest Crow, is eight ounces. 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 Crow and Seagull nest?
Crows build their nests in colonies. The male and female partners start building their nest about a month before the breeding season. Their offspring from previous breeding seasons assist them in nest building. The nests are constructed intellectually, with stronger material laid at the bottom for reinforcement. Crows use all kinds of material available around them to construct the nests. They would include twigs, sticks, hay, plant material, aluminium and copper wire, plastic threads, and wood pieces. The nests are usually placed in tall trees and hidden between trunks for improved safety. However, in cities, crows make their nests in inaccessible parts of tall buildings and billboards. The female incubates the eggs for about 18 days, during which time her partner and other offspring feed her. The newly hatched chicks fly when they are about four weeks old but continue to be fed by their parents and siblings for a longer time. The younger ones live with their parents until they start breeding on their own and sometimes even until they are five years old.
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 Crow and Seagull live?
The average lifespan of Crows is 11-15 years in the wild and over 20-30 years in captivity. Again, this is dependent on the species and the location they live in. Crows in North America are known to live over 30 years.
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 Crow or Seagull migratory birds?
Crows are partially migratory. Those in southern hemisphere are mostly residents. While some birds migrate short distances during winters, some others stay put even in frigid temperatures. Some of them may migrate to breed and some may travel to escape increased urbanization.
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 Crow and Seagull fly in flocks?
A flock of Crows is called a murder. Crows are sociable birds. They live in groups of varying sizes and always roost in flocks. The birds also have their own families consisting of two to 15 members. Different families communicate and cooperate with each other.
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.

They are listed as critically endangered. Efforts to conserve them are underway.
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 Crow and Seagull fly?
Crows usually fly along the same lines every day. They are joined by their flocks as they fly for hunting or towards their roosting sites. They can fly at a speed of 30-60 miles an hour. During migration, some species travel up to 1,740 miles.
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 Crow and Seagull swim?

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.
