The first thing one must accept when trying to learn about the dodo is that we'll probably never know that much about the flightless bird, which died out over 300 years ago in one of the first—if not the first—man-made extinctions. Still, careful study of surviving documents and specimens, as well as a little science, have revealed a bit about the dodo. 

1. THE DODO LIVED ON MAURITIUS.

Part of a chain of three islands east of Madagascar in the Indian Ocean, Mauritius was discovered by the Portuguese in 1507; they set up a base but soon abandoned the island. But it was the Dutch who named it, after Prince Maurice van Nassau, in 1598—which was also when they found the dodo. Vice Admiral Wybran van Warwijck described the bird in his journal: 

Blue parrots are very numerous there, as well as other birds; among which are a kind, conspicuous for their size, larger than our swans, with huge heads only half covered with skin as if clothed with a hood. These birds lack wings, in the place of which 3 or 4 blackish feathers protrude. The tail consists of a few soft incurved feathers, which are ash coloured.

In 1634, Sir Thomas Herbert (who had visited Mariutius in 1627) described the dodo in his book A Relation of Some Yeares Travaille into Afrique and the Greater Asia:

First here only ... is generated the Dodo … her body is round and fat, few weigh less than fifty pound. It is reputed more for wonder than for food, greasie stomackes may seeke after them, but to the delicate they are offensive and of no nourishment. Her visage darts forth melancholy, as sensible of Nature's injurie in framing so great a body to be guided with complementall wings, so small and impotent, that they serve only to prove her bird. The halfe of her head is naked seeming couered with a fine vaile, her bill is crooked downwards, in midst is the trill [nostril], from which part to the end tis a light green, mixed with pale yellow tincture; her eyes are small and like to Diamonds, round and rowling; her clothing downy feathers, her train three small plumes, short and inproportionable, her legs suiting her body, her pounces sharpe, her appetite strong and greedy. Stones and iron are digested, which description will better be conceived in her representation.

He drew the bird, too.

2. ITS MONIKER CAME FROM THE PORTUGUESE.

The Dutch called it walghvodel, or "disgusting bird," because of the toughness of its flesh. "The longer and oftener they were cooked, the less soft and more insipid eating they became. Nevertheless their belly and breast were of a pleasant flavour and easily masticated," van Warwijck wrote in 1598. But the name that stuck, according to Clara Pinto-Correia in her book Return of the Crazy Bird, was derived from the ancient Portuguese word dondo (the modern word is doido) meaning idiot or fool. Pinto-Correia also says that by the end of the 17th century, there were a staggering 78 words for the bird. It had a number of scientific names—Carl Linneaus tried to name it Didus ineptus, or "inept dodo," in 1766—but the one that stuck was Raphus cucullatus (Latin for "bustard" and "hooded," respectively), which was given to the dodo in 1760.

3. IT MAY HAVE BEEN MONOGAMOUS.

It was described as "loyal to its mate and dedicated to its chicks." They also may have lain only one egg at a time in ground nests. That slow reproduction (as well as the fact that the eggs made for easy meals for predators) spelled disaster for the species.

4. THOUGH PLACID AND UNAFRAID OF HUMANS, THE DODO WAS CAPABLE OF DEFENDING ITSELF.

In Crazy Bird, Pinto-Correia relates the slaughter of the dodos, which was occurring long before anyone settled at Mauritius; in one account, sailors killed as many as 25 birds to bring back to the ship. But there is one description of the birds fighting back: "One sailor wrote that if the men were not careful, the birds inflicted severe wounds upon their aggressors with their powerful beaks," Pinto-Correia writes.

5. DODOS WENT TO EUROPE.

No one knows for sure how many—Julian Pender Hume, an avian paleontologist at the Natural History Museum in London, estimates that four or five were shipped with only one or two arriving alive, while others estimate that as many as 14 or 17 birds may have made the trip. But there is evidence at least a few made it there alive. One may have been brought to Europe by Admiral Jacob Cornelius van Neck, who sent the bird to Prague and Hapsburg Rudolf II, monarch of Austria and King of Bohemia and Hungary, in 1600 (more on that in a bit).

Theologian and writer Sir Hamon L'Estrange saw one dodo, displayed as a public attraction, in London in 1683. He wrote:

It was kept in a chamber, and was a great fowle somewhat bigger than the largest Turkey Cock, and so legged and footed, but stouter and thicker and of a more erect shape, coloured before like the breast of a young cock fesan, and on the back a dunn or deare colour. The keeper called it a Dodo, and in the ende of a chymney in the chamber there lay a heape of large pebble stones, wherof hee gave it many in our sight, some as big as nutmegs, and the keeper told us she eats them (conducing to digestion).

6. THE DODO WAS ILLUSTRATED AS FAT AND AWKWARD, BUT IT (PROBABLY) WASN'T.

When we imagine a dodo, we often think of a depiction from one painting in particular—the one at the top of this post. It was created by Rudolf II's one-time court painter, Roelandt Savery, in 1626 (and gifted to the British Museum by George Edwards in 1759). According to Pinto-Correia, Savery left the court after Rudolf's death and afterward often painted the bird from memory, which probably led to inaccuracies. It's also not known if Savery painted a live bird or created his paintings from contemporary accounts and dead specimens.

At any rate, scientists believe the birds were probably drawn from overfed captive subjects or from overstuffed specimens; it's also possible that in the wild, the birds' weight fluctuated dramatically depending on the availability of food.

The first reconstruction of a dodo was put together in 1865 by Richard Owen at the Natural History Museum using fossilized bones and an outline of the bird from one of Savery's paintings. His reconstruction and a scientific description were published, but three years later, Owens realized he had been wrong. It was too late to change public perception, though. Modern evidence suggests that the dodo would have been more upright, with a thinner neck and breast—because flightless birds don't need large muscles in the breast.

7. THE LAST DODO WAS SEEN IN JULY 1681.

Englishman Benjamin Harry, first mate on the British vessel Berkeley Castle, was the last person to spot a dodo on Mauritius and write about it:

Now having a little respitt I will make a little descripti: of ye island first of its Producks and yns of itts parts—ffirst of winged and feathered ffowle ye less passant, are Dodos whose fflesh is very hard, a small sort of Geese reasona...

Sometime after that—just eight decades after the Dutch landed—the bird succumbed to exctinction brought on by hunting, habitat destruction, and the introduction of invasive species like rats and pigs.

8. THERE ARE NO COMPLETE SPECIMENS FROM A SINGLE BIRD.

The dodo skeletons you see at museums have been assembled from sub-fossilized remains. At one point, though, there was a complete specimen. The bird belonged to John Tradescant and was gifted to the Oxford University Natural History Museum in the 1680s. Today, only the head—which still has soft tissue—and the foot remain; the museum burned the rest of the bird on January 8, 1755 because of severe decay, unaware that it was the last complete specimen in the world.

9. AND MANY PEOPLE DIDN'T BELIEVE IT ACTUALLY EXISTED.

You can hardly blame naturalists living 150 years after the dodo's extinction for believing it was a creature made up by sailors. As Hugh Edwin Strickland and Alexander Melville wrote while making their case for the existence of the bird in The Dodo and Its Kindred, published in 1848:

So rapid and complete was their extinction that the vague descriptions given of them by early navigators were long regarded as fabulous or exaggerated, and these birds … became associated in the minds of many person with the Griffin and the Phoenix of mythological antiquity.

10. IT WAS BASICALLY A BIG PIGEON.

During its life and after its extinction, scientists couldn't make up their minds just what kind of bird the dodo was—they grouped it with chickens, vultures, eagles, penguins, or cranes. But a few scientists, including Johannes Theodor Reinhardt, Hugh Edwin Strickland, Alexander Gordon Melville, and Samuel Cabot, thought the bird more closely resembled young pigeons—and they were right. In 2007, biologist Beth Shapiro performed analysis on a DNA sample carefully extracted from the leg bone of the Oxford remains and found that the dodo is a distant relative of the pigeon.

11. IT HAD TWO COUSINS THAT ALSO WENT EXTINCT.

One was the solitaire (Pezophaps solitarius)—so named because it was rarely seen with other birds—a gray and brown flightless bird with a long neck, about the size of a swan, that lived on Rodrigues. It was wiped out by the 1760s. The other was the so-called "white dodo" of Réunion (Didus borbonicus, later called the Réunion Sacred Ibis,Threskiornis solitarius), a yellowish-white bird with black-tipped wings. In an account from 1614 (published in 1626), English sailor John Tatton described the bird as "a great fowl of the bigness of a Turkie, very fat, and so short-winged that they cannot fly, being white, and in a manner tame … In general these birds are in such abundance in these islands that ten sailors can amass in one day enough to feed fourty." At least a couple of the birds were shipped to Europe in 1685, but after that, there are no more accounts; in an 1801 survey of Réunion, none of the birds were found.

11 Facts About French Bulldogs

These cute little dogs are enjoying a serious comeback. Here’s the scoop on the fourth most popular dog breed in America. 

1. FRENCH BULLDOGS HAVE ROOTS IN ENGLAND.

The French bulldog’s origins are murky, but most sources trace their roots to English bulldogs. Lace makers in England were drawn to the toy version of the dog and would use the smaller pups as lap warmers while they worked. When the lace industry moved to France, they took their dogs with them. There, the English bulldogs probably bred with terriers to create bouledogues français, or French bulldogs. 

2. THEY WERE BRED TO BE GREAT COMPANIONS.

Frenchies are affectionate, friendly dogs that were bred to be companions. Although they’re somewhat slow to be housebroken, they get along well with other dogs and aren’t big barkers. The dogs don’t need much exercise, so they are fine in small areas and enjoy the safety of a crate.

3. THEY CAN'T SWIM.

As a result of their squat frame and bulbous head, French bulldogs can’t swim, so pool owners should keep a watchful eye on their pups. Keep in mind that if you plan a beach vacation, your furry friend might feel a little left out. 

4. FLYING IS A PROBLEM FOR THEM, TOO.

French Bulldogs are a brachycephalic breed, meaning they have shorter snouts than other dogs. These pushed-in faces can lead to a variety of breathing problems. This facial structure, coupled with high stress and uncomfortably warm temperatures, can lead to fatal situations for dogs with smaller snouts. Many breeds like bulldogs and pugs have perished while flying, so as a result, many airlines have banned them. 

Luckily there are special airlines just for pets, like Pet Jets. These companies will transport dogs with special needs on their own flights separate from their owners. There's a human on board to take care of any pups that get sick or panic. 

5. THEY MAKE GREAT BABYSITTERS.

When a baby orangutan named Malone was abandoned by his mother, the Twycross Zoo in England didn’t know if he would make it. Luckily, a 9-year-old French bulldog named Bugsy stepped in and took care of the little guy. The pair became fast friends and would even fall asleep together. When Malone was big enough, he joined the other orangutans at the zoo. 

6. THEY'RE SENSITIVE TO CRITICISM.

Frenchies are very sensitive, so they do not take criticism lightly. If you scold a French bulldog, it might take it very seriously and mope around the house. French bulldogs respond better to positive reinforcement and encouragement. 

7. THEY'RE A TALKATIVE BREED. 

French bulldogs might not bark much, but they do like to “talk.” Using a complex system of yawns, yips, and gargles, the dogs can convey the illusion of their own language. Sometimes they will even sing along with you in the car. 

8. THEY HAVE TWO STYLES OF EARS.

Originally, French bulldogs had rose-shaped ears, similar to their larger relative, the English bulldog. English breeders much preferred the shape, but American breeders liked the unique bat ears. When a rose-eared bulldog was featured at the Westminster Kennel Club in 1897, American dog fanciers were very angry

9. THIS CONTROVERSY LED TO THE FORMATION OF THE FRENCH BULL DOG CLUB OF AMERICA.

The FBDCA was founded in protest of the rose-shaped ears. The organization threw its first specialty show in 1898 at New York City’s famed Waldorf-Astoria. The FBDCA website described the event: “amid palms, potted plants, rich rugs and soft divans. Hundreds of engraved invitations were sent out and the cream of New York society showed up. And, of course, rose-eared dogs were not welcomed.”

The somewhat catty efforts of the club led to the breed moving away from rose-shaped ears entirely. Today, French bulldogs feature the bat-shaped ears American breeders fought to showcase. 

10. MOST FRENCH BULLDOGS ARE BORN THROUGH ARTIFICIAL INSEMINATION. 

Due to their unusual proportions, the dogs have a little trouble copulating. Males have a hard time reaching the females, and they often get overheated and exhausted when trying to get things going. As a result, a large majority of French bulldogs are created through artificial insemination. While this measure makes each litter of pups more expensive, it also allows breeders to check for potential problems during the process. 

French bulldogs often also have problems giving birth, so many must undergo a C-section. The operation ensures the dog will not have to weather too much stress and prevents future health complications.

11. CELEBRITIES LOVE FRENCHIES.

Frenchies make plenty of appearances in the tabloids. Celebrities like Lady Gaga, Hugh Jackman, and The Rock have all been seen frolicking with their French bulldogs. Even Leonardo DiCaprio has one—aptly named Django. Hugh Jackman’s Frenchie is named Dali, after the way the dog’s mouth curls like the famous artist’s mustache.

What’s That Thing That Hangs Off a Turkey’s Face?

That thing is called a snood. And it's there to let the other turkeys know that its owner is kind of a big deal.

When a male turkey—known as a tom—wants to mate, he faces two hurdles. One is his potential mates, the female turkeys (a.k.a. hens). In the realm of turkey mating, the hens wield the power of choice and the toms have to get their attention and win the opportunity to reproduce. Come mating season, a tom will strut around, gobble, puff out his chest, fan his tail, and drag his wings to attract the hens, who then pick which of the toms they’ll mate with.

The second problem for a tom looking for love is the other toms in the area. They’re all competing for the same limited number of hens. Sometimes a good mating display isn’t enough to win a mate, and toms will attack and fight each other to secure a hen. 

This is where the snood comes in. That goofy-looking piece of dangling flesh helps a tom both with choosy hens and with competition from rival males. Having a long snood almost always means that a hen will want to mate with him and that another tom will back down from a fight.

DUDES AND THEIR SNOODS

When two toms are trying to establish dominance, they’ll size each other up. Then they'll either fight, or one will flee.

In the late 1990s, Richard Buchholz, an animal behaviorist who focuses on turkeys, wanted to figure out which, if any, characteristics of a tom turkey could predict how they fare in dominance fights. That is, did bigger turkeys tend to win more scuffles? Did older ones? He also wanted to see if the turkeys used any of these predictive cues when sizing each other up. He looked at various characteristics of dominant toms that fight and win, and compared them to those of subordinate toms that lose fights or run from them. Of all the characteristics he looked at, only “relaxed snood length” seemed to be a reliable predictor of how a tom would do in bird-vs-bird combat. The dominant males, the ones who won fights and got a choice mate, had longer snoods.

With that in mind, Buchholz looked at how toms reacted to other toms with snoods of varying sizes. The birds tended to avoid confrontation with other males with longer snoods, and wouldn’t even feed near them. A big snood, this suggests, says to the other turkeys that this is a tom you don’t want to tangle with. Buchholz noted that snood length correlates with age, body mass, and testosterone, so, to competitors, the snood could be a good indicator of a tom’s aggressiveness, age/experience, size, and overall condition and fighting ability.

IN THE SNOOD FOR LOVE

Once the males have established who’s going to have a chance to mate, the final choice goes to the hen. While the mating display is the main draw for getting a hen to check him out, a tom’s snood helps him out again here.

Like it did for the other males, a tom’s snood signals a lot of information to a female assessing potential mates—it indicates how old and how big he is, and even says something about his health. In another study, Buchholz found that longer-snooded toms carried fewer parasites. If a hen wanted to choose a mate with good genes that might help her offspring grow large, live long, and avoid parasites, a tom’s snood is a good advertisement for his genes. In that study, hens showed a clear preference for toms with longer snoods. In another experiment years later, Buchholz found that healthy hens again showed a strong preference for long snoods and that hens with their own parasite problems were less picky about snood length and checked out more potential mates—perhaps, Buchholz thinks, because the hens recognized their own susceptibility to infection and were willing to invest more time searching for a tom with genes for parasite resistance that would complement their own—but still showed some preference for longer ones.

While a snood might look goofy to us, for a turkey, it’s integral to the mating game, signaling to other toms that they should get out of his way and letting hens know that he’s got what they’re looking for.
