Differences between Sparrow and Wren

Sparrow and Wren are two classes of birds that belong to the Passeridae and Troglodytidae families respectively.

Sparrows are one of the most commonly found birds in the world. They are petite birds with a round head and small beak that is shaped like a cone. Their plumage is either brown or grey with white streaks. The feather on their belly is usually white. The birds have a long and stiff tail. An interesting fact about Sparrows is that they have a bone in their tongue. As these are perching birds, they have clawed feet with three forward-pointing and one backward-pointing toe. Sparrows are songbirds that make chirping sounds. There are over 140 species of these birds in the world. They are generally classified as Old World species and New World species. Sparrows are mentioned in mythology and the Bible. Their earliest fossils, found in caves in Israel, are dated back to over 100,000 years.

Wrens are tiny song birds. They have a loud voice. The songs of these passerines are considered to be very pleasant. Hence, they are also known as musician wren, flutist wren, and song wren. Wrens are round and stout. The wings, tail, and back are brown, while the belly is greyish white. There are numerous streaks and spots all over the body. The tail is short and firm. The bill is thin and slightly bent at the tip. The legs are thin and long with feet adapted for perching. The family of Wrens includes 88 species. House Wren, Winter Wren, Rock Wren, Cactus Wren, Eurasian Wren, Giant Wren, Spotted Wren, and Bewick’s Wren are a few of them.

Where are Sparrow and Wren found?

Sparrows prefer thick forests, open fields, agricultural farms, and fringes of forests. However, a large population of Sparrows also live in the parks, gardens, and buildings of cities. The Old World species of Sparrows originally belong to Asia, Africa, and Europe. The New World species have been introduced in North America, South America, Australia, and New Zealand.

Wrens live in open forests, orchards near streams, mountains, gardens, shrubs, and towns. Their species are spread across the world. They can be found in Canada, North America, and South America. The Eurasian species exist in parts of Europe, Africa, and Asia. The name Wren is also used for other distinct birds in Australia and New Zealand.

What do Sparrow and Wren eat?

Sparrows are omnivores. They largely eat seeds and grains like cereals, wheat, rice, oats, and corn. They also eat insects and worms. Occasionally the birds eat human food refuse.

Wrens are either omnivores or insectivores. They chiefly eat insects, worms, spiders, small lizards and frogs. Some of them also eat fruits, berries, and vegetables.

Size of Sparrow and Wren?

When it comes to size, The size of Sparrows depends on the species. The average size is however 0.5-0.6 feet in length. Chestnut Sparrow is the smallest Sparrow with a length of 0.4 feet, while the Parrot-billed Sparrow is the largest with a length of 0.59 feet.. The size of Wrens depends on the species. The smallest Wren is the White-bellied Wren, which is about 10 centimeters long. The Giant Wren, the largest of the species, is around 22 centimeters long. The Eurasian Wren is one of the smallest birds in Europe. It is eight to 12 centimeters long.

The average weight of the Sparrow is 0.84 ounce. The weight of the Chestnut Sparrow is 0.5 ounce and that of the Parrot-billed Sparrow is 1.5 ounce. while The White-bellied Wren weighs about 0.32 ounces, while the Giant Wren is around 1.8 ounces in weight.

Where do Sparrow and Wren nest?

Sparrows build their nests in holes and cavities of small trees, in shrubs, and buildings. They prefer their nests to be closer to the ground. The nests generally look spherical and measure eight to 10 inches in diameter. The female and male partners construct the nest using straw, twigs, roots, leaves, grass, paper, thread, wool, and feather. The eggs are completely white, or bluish white, or greenish white with brown spots. Both partners incubate the eggs. The eggs hatch in 10-14 days. The young ones that are fed by both parents fledge in about two weeks.

Wrens build their nests in hollows of trees, rocks, and buildings. Nests, shaped like domes, are usually made using leaves, twigs, moss, feathers, and other plant material. In most Wren species, the male makes the structure of the nest with the female finishing it up. In other species, the male constructs several nests and the female chooses one to lay the eggs. It may take one to two weeks to build the nests. Wren eggs are pinkish white or pinkish grey with brown speckles. The female takes the responsibility of incubating the eggs for 12-15 days. Once the eggs hatch, both parents take turns to feed the nestlings. The young ones will be able to fledge when they are 12-18 days old but follow the parents for few days to learn about foraging and safeguarding themselves from predators.

How long do Sparrow and Wren live?

Sparrows are known to live for four to seven years. Some species can even live up to 20 years. The House Sparrows live until 23 years in captivity.

The life expectancy of Wrens depends on the species. The average lifespan is two to seven years. The longest known living Wren was eight years old when it was captured for banding in 1986 in California.

Are Sparrow or Wren migratory birds?

Not all Sparrows are migratory. The ones from Canada, North America, northern parts of Europe, and east Asia migrate during winters. The House Sparrows typically do not migrate as they do not encounter harsh weather or scarcity of food in any time of the year. Among the migratory species, American Tree Sparrow migrates from North America and Canada to the USA, while the Savannah Sparrow travels from Alaska to the USA. In northern and central Europe, migration takes place among Eurasian Tree Sparrow that relocates to Africa. The Russet Sparrow is a species from Himalayas that spends its time in south-east Asia during winters.

Most Wren species are migratory. The ones in North America and Canada migrate to the USA and Mexico in winters. They will go back north during March-May. Wrens in the UK are mostly residents. Wren species from northern Europe travel about 1,500 miles to spend their winters in the south. Even in Asia, the same migration pattern occurs. Only the birds from the northern hemisphere typically travel during winters.

Do Sparrow and Wren fly in flocks?

A group of Sparrows is called a flock. The birds are highly sociable. They live in colonies of about 20 birds, which may even extend to about a 100. The birds are always found in groups, foraging, flying, and roosting together. Their nests are also built next to each other during the breeding season. Sparrows are also intelligent birds. They are known for cooperation and teamwork. The birds work together to find food, build nests, preen feathers, and remove lice and parasites from their skin. They chirp incessantly to let their group know about where they are. As Sparrows are tiny birds, living in large flocks also helps in intimidating the predator and also mobbing the predator if required.

A group of Wrens is usually addressed as a herd. Wrens are solitary birds. They forage alone or in pairs. Sometimes they can be spotted in very small groups. On cold nights, however, they roost in packed clusters for warmth. Wrens are extremely territorial. They do not welcome other birds having their nests near theirs. Some species, like the House Wren, are also very aggressive. They can even be acrimonious towards their own species, other birds, and also humans.

Are Sparrow or Wren protected?

Not all species of Sparrows are protected. For example, the House Sparrow is not protected in the USA. It has partial protection in the UK, where shooting it with a licence is allowed. The species is fully protected in Canada.

Wrens are protected under the Migratory Bird Act in the USA and Canada. They are protected in the UK as part of conservation efforts. The bird also appears in the European Union’s list of threatened birds requiring special protection.

Are Sparrow or Wren endangered?

Sparrows are not endangered but their numbers are on a steep decline. Factors affecting the population of Sparrows are loss of habitat, scarcity of food, urbanization, radiation from mobile towers, pollution, use of pesticides in farmlands, and hunting.

Wrens are not primarily endangered birds. Some species like Sedge Wren, Bewick’s Wren, Niceforo’s Wren, Apolinar’s Wren, Fairy Wrens, and Emu Wren are either threatened or endangered. Wrens have a short lifespan, during which time they face threats such as attacks from predators, risk of dying from cold weather, and long flights during migration.

Can Sparrow and Wren fly?

Sparrows fly by taking off directly, flapping their wings, and folding their legs. Their average flying speed is 24-31 miles an hour. The altitude range they can fly at varies for different species. While most of them normally fly at around 500 feet, some fly at around 2,000 feet. During migration they fly 5,000-20,000 feet high and cover 15-600 miles in a day. Sparrows fly in flocks because they are tiny birds and flying in groups supports energy conservation. It will also help them spot and threaten predators. On the ground, Sparrows are commonly seen hopping. They jump forward and backward for scraping mud, leaves, or grass with their toes and search for food underneath.

Wrens are active birds. They are always hopping, running, or taking short flights in search of food. When they have to fly, they take off directly by beating their wings vigorously. Wrens can fly at maximum speed of 20-25 miles an hour. In winters, some species travel as much as 1,500 miles.

Can Sparrow and Wren swim?

Sparrows are not regular swimmers. However, they can swim fast to escape from danger. Some species like the House Sparrow can even swim under water. Sparrows regularly bathe in water, sometimes even in a puddle. They wiggle in water to loosen up the dirt on their feathers and to control body temperature.

Wrens are not water birds. They are also tiny birds without webbed feet. So, they do not swim.

Mating patterns among Sparrow and Wren

Depending on the species, Sparrows start mating when they are five to nine months old. The birds mate in small colonies. During courtship, the male hops around the female with inflated chest, raised tail, and slouched wings. He also chirps and sings for her. The partners copulate until the female can lay eggs. They produce nearly four broods in a breeding season. The female lays one to eight eggs in a clutch. Both partners incubate the eggs and raise the chicks.

Wrens generally attain sexual maturity when they are about a year old. The male perches at the nesting sites that he has prepared, singing throughout the day to attract a partner. The female chooses a nesting site and fills in more twigs, grass, and feathers to complete the nest. This is an indication of her approval to pair with the male. The female Wren raises two broods every breeding season with each clutch consisting of three to 10 eggs. While the female mostly incubates the eggs, the male shares responsibility to feed and protect the young ones.

When is the mating season for Sparrow and Wren ?

The mating season for sparrows depends on geography. It can range from March to August. The courtship can begin as early as January.

The breeding season for Wrens differs as per species and geography. Typically, it is between April and July each year.

Do Sparrow and Wren mate for life?

Sparrows mate for life. They remain monogamous throughout their life and return to the same nesting territory every year. When one of the partners is lost or dies, the surviving partner finds another mate within a few days.

Wrens are not monogamous. The partners are bonded until they raise a brood. They usually stay together until their young ones fledge. While the male may seek another pair much earlier, the female waits until she has completed her maternal duties.

How do Sparrow and Wren sleep?

Sparrows roost in large groups while perching on trees. They may even shelter inside tree holes and cavities. They draw together to stay warm on cold nights. Their usual sleeping posture is head tucked inside plumped up feathers.

Wrens choose cosy and protected locations for sleeping at nights. These locations could include tree holes, bird boxes, corners of buildings, and deserted vehicles. In winters, the birds roost in flocks, huddling to keep warm.

Can Sparrow and Wren be eaten?

Sparrows are widely consumed by people. They are a delicacy in French, Italian, Japanese, and German cuisines. As the law in most countries provide protection only to some species of Sparrows, obtaining the bird meat for food is not restricted.

There are no known instances of humans eating Wren meat. This could be because these birds are tiny with very little flesh. Further, modern laws in many countries prohibit killing of Wrens.

Can you hunt Sparrow or Wren?

Sparrows are hunted for their meat. They are considered a pest by farmers, who kill them to save their crops. Hunting Sparrows is allowed in some countries, while killing them with a licence is permitted in few others.

Hunting of the birds is against the law in several countries. However, Wren Day or Hunt the Wren Day is a tradition followed in many parts of Europe in the month of December. On this day, people hunt Wrens and hang them on top of poles.

Can you feed Sparrow or Wren?

Sparrows can be fed with a mix of seeds, corn, millets, fruits, and insects.

In some countries, it may not be legal to offer food to birds at public places. At bird feeders, the best food you can give Wrens is crickets, worms, peanuts, and berries.
