Differences between Emu and Wren

Emu and Wren are two classes of birds that belong to the Dromaiidae and Troglodytidae families respectively.

Emu is the second largest bird in the world. It is largely depicted in Australian mythology and folklore. The bird is characterized by its long neck and legs. The legs are powerful with each foot having three forward-facing toes. The plumage of Emus is dishevelled. It is usually greyish brown with black tips for absorption of ultra violet radiation. The feathers are silky, soft, and absorb water. The tail feathers are however stiff and are used to intimidate predators. Emus are terrestrial and have small vestigial wings. Emus have exceptionally large eyes that are red with black iris. They have two eyelids – while one blinks, the other blocks dust. The beaks are short and strong. They are used for plucking rough foliage.

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 Emu and Wren found?

Emus live in woodlands, deserts, eucalyptus forests, and regions covered with shrubs. The birds exist only in Australia. Two of their subspecies once existed in King Island and Tasmania. They are now extinct.

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 Emu and Wren eat?

Emus are carnivores although they primarily eat plants. The birds typically eat healthiest parts of the plants, such as fruits, berries, flowers, leaves, grains, and seeds. When accessible, they also eat insects, lizards, snakes, mice, and rodents.

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.

Here are a few pointers about the eating patterns between Emu and Wren

• Neither Emu nor Wren eat Fish.
• Both Emu and Wren eat Frogs.
• Both Emu and Wren eat Lizards.
• Emu do eat Snakes while Wren may not eat Snakes.
• Neither Emu nor Wren eat Turtles.
• Neither Emu nor Wren eat Squirrels.
• Emu and Wren do not eat Gophers.
• Both Emu and Wren do not eat Baby Ducks.
• Emu do eat Mice while Wren may not eat Mice.

Size of Emu and Wren?

When it comes to size, Emus are only smaller than Ostriches. They are about 5.8 feet in height.. 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.

Emus are well-built birds. The male birds weigh about 71 pounds, while the females weigh around 81 pounds. while The White-bellied Wren weighs about 0.32 ounces, while the Giant Wren is around 1.8 ounces in weight.

Where do Emu and Wren nest?

Emus nest on the ground as they cannot get on top of trees or buildings. The nests rest on the surface of the ground or in shallow craters dug up by the partners. The male Emu usually builds the nest with grass, twigs, and leaves. The nests are typically one to two meters in diameter. Emu eggs are dark green with blue spots when they are laid. They eventually turn greyish or brownish owing to exposure to sunlight. The male bird incubates the eggs continuously without food or water and loses considerable weight by the time the eggs hatch. The young ones emerge in about 56 days. The chicks of Emus are five inches tall and about 17.6 ounces in weight when they hatch. They are born with brown and white stripes that fade after three months. During this time, they will not be able to regulate their body temperature. Hence, their father takes care of them for nearly six months. The chicks stay with the father and their siblings for about one and a half years.

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 Emu and Wren live?

The average age of Emus is 10-20 years in the wild. In captivity, they live up to 35 years. The oldest known lived Emu was 38 years old.

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 Emu or Wren migratory birds?

Emus are nomadic birds. Their migratory pattern depends on their location in Australia. The birds from western parts relocate to south-west in winters and north-east in summers. However, the Emus in eastern parts of the country do not migrate long distances. They do not follow a standard migratory pattern. It is understood that food sources and weather are the chief factors that drive the migration of Emus. They either migrate in pairs or in flocks.

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 Emu and Wren fly in flocks?

A flock of Emus is known as a mob. These birds are solitary, shy, and curious. They may also fight amongst themselves. They live alone most of the time. The exception is when they pair up during the breeding season. Also, when they have to travel in quest for new food sources, they form large flocks.

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 Emu or Wren protected?

Emus are protected in Australia. Capturing Emus from the wild is illegal. However, they can be reared in farms with a licence. Emus are commercially bred in the country as trading of their meat, eggs, feathers, and oil is widespread.

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 Emu or Wren endangered?

Emus exist in large populations in Australia. They are listed as species of least concern by the International Union for Conservation of Nature and Natural Resources. Emus however face several threats. Birds like eagles and hawks attack Emu chicks, while snakes and other predators steal eggs from the nest. Migrating Emus often get killed in large numbers at dog fences of agricultural lands. Further, some of them also die in road accidents. Forest fires, drought, and loss of habitat due to urbanization and claiming of forest land for cropping are other threats that these birds confront.

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 Emu and Wren fly?

Emus are flightless birds. Their bone structure does not support flying. Further, they are too heavy to lift themselves for aviation. Emus are nevertheless great sprinters. Their powerful legs, calf muscles, and toes permit them to run as fast as 30 miles an hour. They flap their wings for balance while running. Emus travel long distances in search of food and for migration. They do this on foot, covering nearly 310 miles each time. On a daily basis, the birds commute about 15 miles.

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 Emu and Wren swim?

Emus are not regular swimmers. However, they can swim well if they have to with the help of their strong legs. They enjoy swimming and waters. They also like to bathe by rolling themselves in shallow waters and shaking up to remove water from their soaked feathers.

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

Mating patterns among Emu and Wren

Emus become sexually mature when they are 1.5 to two years old. During courtship, the male makes the first move by encircling the female with his dances and head movements. When the female accepts the proposal to mate, she strides around the male by making specific calls. The partners strut together, surround each other, dance together, tilt their heads bashfully, and flutter their feathers as part of mating. The female lays an egg per three to four days in the nest built by her partner. She generally lays 30-50 eggs each breeding season. The male incubates the eggs and takes care of the hatched chicks by feeding and protecting them.

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 Emu and Wren ?

Mating season for Emus occur during February-June although they start pairing in December and January.

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

Do Emu and Wren mate for life?

Emus are monogamous socially as they live with their partners most times of the year. However, after mating with a male and laying eggs at his nest, the female mates with new partners and lays multiple clutches of eggs at different nesting sites. During this time, her original partner carries out his duties of incubating the eggs and raising his chicks. For this reason, Emu symbolizes fatherhood in the folklore and culture of Australia.

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 Emu and Wren sleep?

Emus retire for the day after sunset. They lay down on the ground to sleep. While the younger birds stretch their neck perpendicular to the body, the adults generally fold the neck, resting it on their back. The eyes remain closed when the birds are in slumber. While asleep, Emus also arrange their feathers in a such way that if it rains, the water flows down. The birds do not sleep uninterruptedly until sunrise. They wake up once in about two hours for defecating and feeding.

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 Emu and Wren be eaten?

Emu meat is widely consumed and relished. It is considered to be rich in proteins, vitamin C, and iron. While it is illegal to capture Emus from the wild for their meat, rearing of the birds for meat and eggs is permitted.

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 Emu or Wren?

The laws in Australia do not allow hunting of Emus in the wild. However, culling of the birds on private properties under a licence is permitted.

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 Emu or Wren?

In captivity, such as breeding farms, Emus are fed with vegetables, insects, worms, and poultry feed.

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.
