Mandarin Duck

 One of the world’s most attractive duck species is also one of the oldest. For hundreds of years Mandarin Ducks have been found in the forests of Asia and, in the West, they have been kept and bred for more than 200 years.

Appearance

The drake is by far the more spectacular bird with a swept back erectile crest on top of its head. The drake’s forehead is greenish black and the crest area is purple with a white splash on the side of the head. The breast is maroon with a base colour of chestnut. Slightly curled wing feathers, known as ‘sails’, sit up along the back and are coloured bright orange. The hen is grey with a small crest.

They are small birds, weighing only 500g which is just about the size of a homing pigeon. Mandarin ducks also have sharp claws on their webbed feet which means they can perch and nest high up in trees in their native state. Captive Mandarin ducks are usually fenced and their wings pinioned (the tip of the wing removed) to prevent them from flying.

Temperament

Variable, and probably depends on the amount of handling the duck receives.

Health and feeding

Feed Mandarin ducks incorrectly and they will not raise any babies. Most people who own Mandarin ducks rarely produce any ducklings, blaming it on past in-breeding. This is nonsense. The birds fail to breed because they have fatty deposits around their testicles or ovaries caused by poor diet. If Mandarin ducks can find budgie seed or parrot seed, they gorge themselves on it and become quite unhealthy.

Correct feeding entails dividing the year into two bits: the lean non-breeding period and the breeding period. During the lean non-breeding period (mainly in winter) the birds should be fed meagre rations of wheat, corn, sorghum and natural grassy forage.

During the breeding season, from early Spring, feed chicken grower crumbles and supplement the feeding with insects and natural forage.

This general principle of a “Rising Plane of Nutrition” stimulates successful breeding in dogs, cats, horses, cattle, humans and many other species. Clean drinking water is essential.

Breeding

Mandarin ducks demand very specific breeding sites preferring to nest near water and, ideally, with the nest box accessed from the water, ie: facing a pond or lake, and raised on a platform a meter or more above ground level, reached by a ramp. In the wild the ducks may nest 20m up trees. Females are considered good mothers if permitted to raise their own babies.

It’s also important that the ducks aren’t too fat leading up to breeding season, as they will not breed if carrying too much weight. A simple diet of grower pellets (available from stock supplies and pet shops) is all they need prior to and during the breeding season.

Mandarin Duck Facts

1. What is a mandarin duck?

Mandarin ducks are small, colorful ducks that originated in East Asia. Their name is Chinese, but they also have a lot of cultural significance in places like Japan and Korea.

They can currently be found all around the world thanks to travelers in the 19th century who established colonies of mandarin ducks in the west.

2. Where have I seen a mandarin duck before?

You might be familiar with mandarin ducks as “wedding ducks.” Since they mate for life, they’re a popular symbol of love and fidelity in Asian countries.

In the olden days, a man might buy or catch a pair of mandarin ducks to give to his bride’s family; in recent times, however, couples just use pictures and carvings of mandarin ducks as wedding decorations. They are always presented in pairs.

You might also recognize mandarin ducks as a general symbol of romance. There are lots of idioms about them in various languages:

  • In China, “yuanyang xi shui” (鸳鸯戏水) means “two mandarin ducks playing in water” and refers to an affectionate couple.
  • In Japan, “oshidori fufu” (鴛鴦夫婦) means “husband and wife mandarin ducks” and is used in the same way as the phrase “a couple of lovebirds.”

3. What does a mandarin duck look like?

Mandarin ducks are known for their vivid coloring. They’re waddling little rainbows of red, orange, purple, blue and green, and if you look closely, you can spot some burgundy highlights as well.

In an interesting twist, only the males of the species have this eye-popping plumage. The females are mostly gray and white.

Another distinctive feature of the mandarin duck is the presence of “sails” on its back. These are actually large, upright feathers, but they look so much like the sails of a boat that the comparison is unavoidable.

4. Do mandarin ducks have gills?

No. As members of the duck family, mandarin ducks don’t have gills.

You only hear this word around them because of their unusual neck feathers that have a ruffled, accordion-like appearance. They really stand out from the usual smooth-necked ducks, so some people refer to them as “gills.”

5. What do mandarin ducks eat?

Mandarin ducks love grains, seeds, acorns and other forms of plant life. They aren’t total vegetarians, however, especially in the summer when lakes and ponds are teeming with life.

They enjoy everything from frogs to fish, and they have no qualms about chasing down a tasty snail. They’ve even been known to catch small snakes!

Their diets are a bit more restricted in winter, especially in cold-weather regions. This is when they’ll turn to their trusty grains, pines, seeds, and weeds.

When in captivity, mandarin ducks are usually fed plants and small insects. Some zoos will toss in things like baby carrots and bean sprouts for a treat.

6. Can you feed mandarin ducks? What can you feed them?

If you spot a mandarin duck at your local park, you might be tempted to fling them the crusts of your sandwich.

7. How big is a mandarin duck? How much do they weigh?

Mandarin ducks are mid-sized birds. They usually measure about 15-20 inches across with a wingspan of 25-30 inches. They can weigh up to 1.5 pounds.

8. Do mandarin ducks molt?

Like many other waterfowl, male mandarin ducks undergo a molting process. This means that they periodically shed their feathers and grow new ones.

They’ll look a lot like their female counterparts at this time; without their coat of many colors, they have a simple gray or brown appearance. This is called their “eclipse” plumage.

9. How long do mandarin ducks live?

There hasn’t been a lot of research into the lifespans of mandarin ducks. Some sources say that they live around 6-7 years; others think that they can clock around 10 years.

According to the Animal Aging and Longevity Database, their maximum recorded longevity is 10.4 years, but it’s suggested that they might have the potential to live twice as long.

10. Are mandarin ducks rare or endangered?

The good news is that mandarin ducks aren’t endangered. They’re classified under “least concern” in the extinction hierarchy of the International Union for Conservation of Nature (IUCN).

The bad news is that their population is on the decline, so you might want to keep an eye on their status in upcoming years.

11. Are mandarin ducks protected?

Since they aren’t endangered, mandarin ducks don’t have any special protections in place. According to the IUCN, there are about 65,000-66,000 mandarin ducks thriving in zoos and wetlands around the world.

12. Are mandarin ducks related to wood ducks?

Yes. Mandarin ducks and wood ducks are the only two species under the “aix” classification of duck.

Their family tree breaks down like this:

  • Class: Aves (birds)
  • Order: Anseriformes (waterfowl)
  • Family: Anatidae (ducks, geese, swans)
  • Genus: Aix (mandarin ducks and wood ducks)

Mandarin ducks are known as aix galericulata, and wood ducks are called aix sponsa.

13. Can you eat a mandarin duck? What do they taste like?

Mandarin ducks are safe to eat in the sense that they won’t make you sick. However, everyone agrees that they taste terrible!

Maybe it’s because of their diet of worms and weeds; maybe there’s just something naturally repulsive about their meat. But one of the reasons that they’re doing so well in the wild is because they aren’t being hunted for food.

14. Are mandarin ducks monogamous? Do they mate for life?

Yes. Once a mandarin duck finds a partner, they remain with that partner until their death.

This is why they’re seen as such romantic symbols in traditional Asian cultures; they represent a lifelong commitment.

15. How many eggs do mandarin ducks lay?

Female mandarin ducks lay between 9-12 eggs at a time. Most of them create their own nests in the holes and cavities of densely-wooded trees.

But mandarin ducks have also been known to participate in “egg-dumping” where they lay their eggs in another female’s nest. This can result in nests with dozens of eggs jostling for space!

16. What is the mandarin duck habitat? Do mandarin ducks nest in trees?

Mandarin ducks do enjoy nesting in trees. The coverage provides warmth, stability, and safety from predators.

When they’re not laying eggs, however, you’ll mostly find mandarin ducks making habitats in the low grasses and woodland areas surrounding bodies of water. They also like marshes, swamps, lagoons, and water meadows.

17. How do mandarin ducks treat their young?

Mothers are the primary caregivers of baby mandarin ducks. After laying their eggs, they’ll protect the nest for 28-33 days until everyone hatches.

Then, the moms will jump to the ground and encourage their ducklings to do the same. Even when the trees are very tall, it doesn’t hurt the babies to take the plunge. Their fluffy padding and low body weight protect them from damage.

Fathers are a bit more hands-off when it comes to child rearing. They might protect the nest during the initial egg-laying stages, but they usually leave before the ducklings are born. They have to go and molt.

18. Where do mandarin ducks live? Are mandarin ducks found outside of Asia?

Mandarin ducks are naturally found in China, Japan and the lower parts of Russia. There’s also a sizeable population in Great Britain because of those early-century travelers that we’ve already discussed.

Amusingly, there are also scattered settlements of mandarin ducks in various U.S. states. It’s believed that these rogue birds escaped from captivity and started breeding in the wild. Their populations aren’t huge, but they cause a stir whenever they pop up in unexpected places.

19. Do mandarin ducks fly?

Mandarin ducks are extremely skilled fliers. In fact, they’re known for their maneuverability; one of the reasons that females make their nests in trees is because they’re able to fly and perch in places where other creatures struggle to go.

It isn’t all business, however. Mandarin ducks also take to the air to play games of tag. They’ll chase each other through the trees and along the water in a way that looks like fighting but is actually just fun.

20. Can mandarin ducks swim?

Of course! All ducks can swim. That’s why they have webbed feet.

In the case of mandarin ducks, they’re just as adept at swimming in the water as they are at flying through the air, and they aren’t afraid to stick their whole heads underwater when searching for food.

21. Do mandarin ducks sound like ducks found in America? What sound does a mandarin duck make?

Here’s one of those fun mandarin duck facts that you can share at parties: Mandarin ducks don’t quack.

They make small, almost chirping noises while going about their daily activities, and they can let loose shrill and alarm-like sounds to signal danger, but they don’t quack like North American ducks.

There are also subtle differences between male and female mandarin duck sounds, but you have to have an experienced ear to distinguish them.

22. Are mandarin ducks loud?

Mandarin ducks are known to be quieter than other ducks. But all bets are off when a predator is near! They’ll sound the alarm to others in the flock by making a high-pitched call.

23. Are there any cool mutations found in mandarin ducks?

Yes! Though they’re known for their colorful plumage, some mandarin ducks are born with recessive genes that turn them completely white.

They still have the “sails” on their back, and their neck feathers are still ruffled like gills, but nothing is pigmented. They aren’t albino, but it’s thought that the whiteness is probably caused by something similar like leucism.

24. What are some of the threats facing mandarin ducks?

They might not be endangered, but there are still a few things that can hamper growth in mandarin duck communities:

Natural predators can kill and eat them. They’re vulnerable to minks, otters, polecats, eagle-owls and raccoon-dogs.

Loggers are destroying their habitats. While they can live without trees, it’s difficult to nest without them, and this translates to lower population levels over time.

Some hunters kill them as prizes for their beauty. Other hunters might mistake them for different duck species without realizing that mandarin ducks won’t be a tasty dinner.

25. How do mandarin ducks protect themselves from predators?

On the “fight or flight” scale, mandarin ducks choose the latter. They’ll quite literally fly away from danger.

Things get a bit more complicated when it’s a mother protecting her young.

Since she can’t just book it, she’ll usually pretend to be injured to draw the predator away from her babies. This gives the ducklings enough time to waddle or fly away, and their mother will rejoin them when it’s safe.

26. Do mandarin ducks have any mating rituals?

Mandarin ducks have a very specific way of attracting a mate.

The male uses his colorful plumage to catch a female’s eye, and he’ll engage in preening and shivering behavior to signify both his interest and intent. He’ll also raise his “sail” feather in a courtship ritual.

27. Can I keep a mandarin duck as a pet?

This is one of those lesser-known mandarin duck facts that surprises people when they learn it, but yes!

If you live in the right kind of environment, you can buy mandarin ducks and keep them on your property. They’re more free-range animals than house pets, but as long as you provide fresh water and nesting boxes, they’ll be content.

American Goldfinch

Starting in spring and continuing through much of summer, male goldfinches are a bright lemon yellow with black foreheads, black wings and white markings above and beneath their tails. (Females are olive above and dull yellow beneath.) Come winter, both sexes turn a drab brown—so dull they often are mistaken for sparrows. The change occurs through the process of molting. The American goldfinch is the only finch species that molts its body feathers twice a year, once in late winter and again in late summer.

Late Breeders

Frequent molting is both time-consuming and physiologically taxing for the birds. Some scientists suggest this may be the reason goldfinches breed so late in the season—rarely beginning in earnest until mid-July. Another possibility is that the birds wait to nest until thistle, milkweed and other plants have produced fibrous seeds, which goldfinches not only eat but also use to build their nests.

Goldfinches are among the strictest vegetarians in the bird world, selecting an entirely vegetable diet and only inadvertently swallowing an occasional insect. This diet helps protect goldfinches from cowbirds: Though the parasitic birds may lay eggs in goldfinch nests, the hatchlings cannot survive long on an all-seed diet.

Color and Fitness

 Choosy female goldfinches prefer to mate with males that have the brightest plumage. “Color matters”.

Why? One possibility stems from the fact that the male’s color comes from carotenoid pigments (the chemicals that make carrots orange) that he acquires through his diet. By selecting the brightest males, females also may be getting the best food providers for their offspring.

Growth of Chick Emperor Penguin : When Parent Stop Feeding

 Penguins are some of the most unusual birds on earth. These semi-aquatic, flightless hunters can thrive in nearly any climate, from the tropics to the tundra. The penguin life cycle is fascinatingly intricate, especially that of emperor penguins. These birds are one of the few animal species that can live and breed in frigid Antarctica.

Many species of penguins exist, but one of the most well-known and fascinating is the emperor penguin. These penguins live and breed in frigid Antarctica. Parents feed chicks regurgitated food and keep them warm inside of brood pouches, until the chicks develop cold-resistant down.

Matting and Breeding in Antarctica

Male penguins give courtship displays to females, which involve calls and bobbing head movements. If a female is impressed by his display, she will join him, signaling to the rest of the colony that they have formed a mated pair.

Emperor penguins live in colonies all their lives, though they only huddle together when weather gets harsh. Adult emperor penguins cannot breed until they are around three years old, and usually wait around two to three years after reaching sexual maturity to begin the process of finding a mate.

Emperor Penguin Eggs

Female penguins lay just one egg at a time. The eggs have thick shells, to insulate them from the cold. Most birds nest either in trees or on the ground. However, emperor penguin eggs would freeze in the open air, which means that the female penguin must pass her egg to her partner’s brood pouch as soon as she lays it. This process is dangerous, since the egg will die within moments if it touches the frigid ground. 

Once the transfer is complete, the female penguins leave together, for the sea. The males watch after the egg for most of its incubation, until the females return around two months later. During this time, males may lose up to half their body weight.

When the female returns, the egg, or in some cases, the newly hatched chick, is transferred to the mother’s pouch, and the males leave to find food for themselves and their families.

From chick to breeding adult, emperor penguins have one of the most complex life cycles of any bird, due to the extreme conditions they must bear, especially during mating season. Because of their physical and behavioral adaptations, these incredible birds are able to reproduce and thrive in some of the harshest conditions on earth.

Chicks

    Emperor penguins are the tallest and heaviest penguins in the world, with newborns weighing around 11 ounces, and usually being around a foot long. For comparison, the world’s smallest penguin species, the little penguin, is around this size when fully grown. Emperor penguin chicks come into the world during the harsh Antarctic winter, the most frigid winter on earth with temperatures that can easily drop to -100 degrees Fahrenheit. Because of this, and because chicks do not develop proper down (warm, insulating feathers) until a few weeks of age, they must spend the first few weeks of their lives being warmed by their parents. Male and female emperor penguins have an insulated pouch, called a brood pouch, between their feet, just below their bellies. Chicks must stay in this pouch until their down develops, about 45 days after they hatch.

Colonies

Emperor penguin chicks are born into large groups called colonies. Penguins of all species are social, and stick together in colonies, even those that live in tropical climates. Emperor penguin colonies spread out in summer, but huddle together for warmth in winter. 

 Sometimes, chicks hatch while their mothers are away, collecting food. The chick’s father may feed the chick a kind of “milk” (produced by special glands in his throat) to help the chick survive until the mother returns. Flamingos, pigeons and emperor penguins are the only birds on earth that can produce such “milk.” Even other species of penguin are not capable of producing it.

Once the mother returns, the father penguin carefully transfers their chick to her brood pouch (the adults touch toes and nudge the baby from one pouch to another) and then leaves himself, to find food at sea. The mother penguin feeds her chick the food she gathered during her time away, by regurgitating, or vomiting, food into the chick’s mouth. Once a chick’s down develops, it will leave the brood pouches of its parents and join other chicks in its colony, huddling in a group called a crèche for warmth. The chick’s parents will still return, in shifts, to feed the chick during this time.

Growth of Chick : When Parent Stop Feeding

Over the course of a few months, emperor penguin chicks grow to between 3 and 4 feet tall. Their baby down falls out and is gradually replaced with adult feathers. This process is called molting. Once a penguin chick has most of its adult feathers, its parents stop feeding it. As spring arrives, the penguin parents leave for the sea. Chicks must go without food until their adult feathers completely come in, which can take up to a month, at which point they are able to trek to the sea themselves and hunt.

Waterproof Feathers

     Like all penguin species, adult emperor penguins have sleek, waterproof feathers. This is vitally important because emperor penguins do all of their hunting in the water. All penguin species eat a diet of mostly seafood, and emperor penguins are no exception. 

They can eat all manner of aquatic animals, from squid to crabs to fish. Their bodies are built for hunting underwater, from their strong flippers to their webbed feet. Despite their large size, adult emperor penguins are very fast underwater, which helps them hunt quick prey such as Antarctic silverfish. It also helps them avoid predators such as leopard seals and killer whales.
