Differences between Owl and Wren

Owl and Wren are two classes of birds that belong to the Tytonidae and Troglodytidae families respectively.

Owl is a large nocturnal bird. It has a round and flat face with hooked beaks, static eyes, and large ears. Its neck is flexible and can turn over 180 degrees on both sides. This allows the bird to look around and backward even with its fixed eyes. The bird cannot see color but its visual clarity is sharp. Its ears are asymmetrical but acute in discerning sounds from different dimensions. Owl is commonly seen standing in upright position. Its plumage is soft and heavy. The color varies for different species, from grey to brown to reddish brown. The plumage mostly have markings on them, camouflaging the owl amidst dense foliage. The fossils of owls are dated back to over 65.5 million years. At present, there are about 250 species in the Owl family.

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 Owl and Wren found?

Owls live in diverse habitats such as forests, mountains, plains, and deserts. The Snowy Owl lives in the frigid regions of North Pole. Species like Great Horned Owl and Barred Owl can be found in cities. Owls can be found in all countries of the world except Antarctica.

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 Owl and Wren eat?

Owls are carnivorous birds. Their diet depends on food sources in their environment. Owls eat insects, rodents, crabs, snails, small birds, fish, amphibians, and reptiles.

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 Owl and Wren?

When it comes to size, The owls measure 0.4-2.3 feet in length with a wingspan of 1-6.6 feet. Elf Owl, which is the smallest in the family, is about 0.5 feet tall. Blakiston Fish Owl, the largest Owl species, is 2.3 feet tall.. 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 weight of Owls varies for different species. Elf Owl weighs about 1.5 ounce, while the large North American Owl weighs about 8.8 pounds. while The White-bellied Wren weighs about 0.32 ounces, while the Giant Wren is around 1.8 ounces in weight.

Where do Owl and Wren nest?

Owls do not build nests. They use holes in trees, quiet places in barns and buildings, caves, natural cavities in river banks, and nests of other birds to lay their eggs. The female Owl starts incubating the eggs when the first one is laid. She lays eggs two to three days apart. Consequently, the eggs do not hatch synchronously. In the nesting season, the female develops additional feathers, called brood patch, on her belly to provide warmth during incubation. The eggs hatch 32 days after incubation. The young ones fledge when they are six to eight weeks old.

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 Owl and Wren live?

The average lifespan of Owls in the wild is five to 12 years. Larger Owls may live longer, sometimes up to 25 years. The oldest Owl, which was a female Great Horned Owl, turned 50 years in 2012. She lived in captivity at the San Francisco Zoo.

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 Owl or Wren migratory birds?

Not all Owl species are migratory. Some relocate to warmer regions during winters. However, some Owls remain in their territories even in winters. The Great Gray Owl and the Great Horned Owl of Canada are resident species. The Snowy Owl that lives in the North Pole migrates to Canada and USA during winters. In Europe, the Scops Owls migrates to the tip of the Sahara Desert. The Short-Eared Owl is another migratory Owl from India that travels long distances, sometimes even crossing oceans.

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 Owl and Wren fly in flocks?

A group of Owls is called a parliament. Owls are extreme loners and prefer solitary existence. They rarely flock aside the breeding season. They sometimes roost in small groups or in pairs for warmth in cold temperatures.

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 Owl or Wren protected?

Owls are protected in most countries like the USA, UK, India, Canada, and Japan. They do not enjoy protection in some countries, while in some others only the endangered species are protected.

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 Owl or Wren endangered?

Some species of Owls are endangered and face threat of extinction. These include Pernambuco Pygmy Owl, Siau Scops Owl, Forest Owl, Moheli Scops Owl, Congo Bay Owl, and Long-Whiskered Owlet. The population of Owls is threatened by loss of habitat, lack of food sources, hunting, and climate change.

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 Owl and Wren fly?

Owls are known to fly without making any sound. The comb-like design on the edges of their feathers and their large wings enable them to fly noiselessly. They fly slowly, without flapping their wings too much. Some species of Owls fly at a speed of just two miles an hour, while the faster species can reach 40 miles per hour.

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 Owl and Wren swim?

Owls are not natural swimmers. They do not have webbed feet. However, they can manage to swim if they happen to accidentally fall in water.

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

Mating patterns among Owl and Wren

Owls start mating when they are two to three years old. During the mating season, the male and female Owls perform mating dances. They also hoot mating calls that boost their bond and keep away other Owls from their territory. The male may get a prey as offering to the female to woo her. In some species, partners may engage in giggling and snapping of bills as part of mating ritual. The female may lay one to 15 eggs in a breeding season, however not all at once. It is her responsibility to lay eggs, incubate and hatch them. Once the chicks are born, the male may fetch food for them and give it to the female.

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 Owl and Wren ?

The mating season for Owls is generally spring every year. However, some species mate during winter months.

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

Do Owl and Wren mate for life?

Owls are devoted partners. They mate for life. They also use the same nesting site year after year.

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 Owl and Wren sleep?

Owls are nocturnal birds. They sleep either on trees or on the ground while standing and keeping their eyes closed. Most species are awake during the night when they hunt. They mostly sleep during the day.

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 Owl and Wren be eaten?

Humans are not known to have consumed Owls. The birds do not have much meat on them. Their taste is known to be unpalatable.

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 Owl or Wren?

Owls are typically not hunted. Only in cases when they cause trouble, people hunt them or capture them and release them in the wild. Hunting or harming Owls is not allowed in many countries.

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 Owl or Wren?

Most countries do not permit owning or feeding of Owls. In captivity, the birds are fed rodents, chicken, meat, and worms.

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.
