Differences between Jackdaw and Seagull

Jackdaw and Seagull are two classes of birds that belong to the Corvidae and Laridae families respectively.

Jackdaws are small, strong, intelligent, and curious birds that look like Crows. They are quick in picking up new skills. They are characterized by black beaks and black plumage that has a purplish tinge. The plumage of the male birds is likely to become grey as they age. The black legs are strong with four toes and long sharp talons. The eyes are black, while the irises are white. The birds are known for the shrill calls they make.

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 Jackdaw and Seagull found?

Jackdaws are highly adaptable birds. They can be found in forests, open fields, gardens, and cities. The birds exist in most parts of Europe besides north Africa, western Asia, and the Himalayas. Few of them were reported to have been spotted in North America in 1984. A species of Grackle is referred to as Jackdaw in the USA.

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 Jackdaw and Seagull eat?

Jackdaws are omnivorous. They eat insects, worms, eggs, spiders, snails, small mammals, reptiles, berries, seeds, and fruits. The birds also eat carrion and waste from bins and landfills.

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.

Size of Jackdaw and Seagull?

When it comes to size, Jackdaws are 1.11-1.27 feet long. They have a wingspan of 2.3 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.

Jackdaws are not heavy although they are sturdy. They weigh about 8.8 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 Jackdaw and Seagull nest?

Jackdaws are not fussy about their nests. They construct them with sticks and twigs and cover them with moss, hair, or dung. They build the nests in holes and cavities of trees, chimneys, buildings, and rooftops. They may also use nests built by other birds. The eggs are bluish green in color with brown spots. The female incubates them for about 18 days. After hatching, the chicks are dependent on the parents for food. The male and female share the responsibility of feeding them. The chicks fledge when they are 28-35 days old but continue to be reliant on the parents for food for another four weeks. The eggs in the brood hatch asynchronously. When the last egg hatches, the earlier hatched chicks are probably old enough to fledge. Therefore, the parents may abandon the new-borns speculating that they may not survive.

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 Jackdaw and Seagull live?

The average lifespan of Jackdaws is five years. The Western Jackdaw or Eurasian Jackdaw found in Europe, parts of Africa, central Asia, and Himalayas is known to live up to 20 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 Jackdaw or Seagull migratory birds?

Not all Jackdaws are migratory. The ones in the UK are mostly residents or may travel a few miles during winter. Western Jackdaws from northern Europe may move south. The Jackdaws living in northern Africa are also mostly residents. The ones from Russia may travel to north-west Europe.

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 Jackdaw and Seagull fly in flocks?

Clattering or train refers to a group of Jackdaws. They are extremely gregarious and follow a hierarchy in their colonies. Jackdaws spend most of their time with their community. They forage, roost, and move around in groups. Research shows that the birds communicate efficiently through their eyes and also engage in sophisticated communication. They are capable of warning each other about predators or human attacks. They can remember human faces, perform tricks, and steal things. The birds also share their food and objects, a trait that is unusual in birds.

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 Jackdaw or Seagull protected?

Are Jackdaw or Seagull endangered?

The International Union for Conservation of Nature has listed Jackdaws as species of least concern. There was a reduction in their population in the UK during 1970s, but the numbers have recovered in the 21st century. Jackdaws presently flourish in all habitats they live in.

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.
