This is America’s 250th birthday, and in signature Commonplace Fun Facts fashion, we’re celebrating the nation’s history with the proper combination of patriotism, curiosity, and a fascination with the quirky stories that generally don’t make it into the textbooks.

This is Part 4 of our series of 250 fun facts about America. In Part 1, we looked at presidents and politicians. In Part 2, we explored wars, disasters, and decisions that probably needed another meeting. In Part 3, we traveled through all 50 states without stopping for gas or snacks, while maintaining that we were never lost — we were just taking the scenic route.

Now we turn to the non-human players in our national drama and share 50 fun facts about animals that shaped American history.

That may sound like an unlikely little detour, but animals have been playing a role in American history from the beginning. They have served as national symbols, military heroes, presidential pets, transportation systems, conservation warnings, disaster scapegoats, scientific test subjects, movie stars, mail clerks, fire-prevention mascots, and, in some places, elected officials. This is both a beautiful tribute to the animal kingdom and proof that democracy is more pet-friendly than originally advertised.

Some of these creatures were heroic. Some were famous. Some were unfairly blamed. All of them left pawprints, hoofprints, wingbeats, claw marks, or other assorted evidence on the great American experiment.

National Symbols, Founding-Era Animals, and Other Creatures Who Got Involved Early

1. The bald eagle became America’s great national symbol long before it became the official national bird. The bald eagle appeared on the Great Seal of the United States in 1782, showing up with arrows, an olive branch, and the general expression of a bird that has read the Constitution and is prepared to enforce it. Oddly enough, Congress did not formally designate it as the national bird until 2024. Nothing says “swift national action” like a 242-year follow-up memo. One famous eagle associated with U.S. coin design was named Peter. His preserved body is on display at the U.S. Mint in Philadelphia, where Mint artists still study him when working on eagle designs.
2. Benjamin Franklin did not seriously campaign for the turkey as the national bird. The familiar story is not quite right. Franklin did criticize the bald eagle in a private letter and called the turkey a more respectable bird, but he was not mounting a formal turkey-for-president campaign. Still, it is a fun thought: America could have spent two centuries rallying beneath the noble gobble.
3. The rattlesnake became one of America’s earliest political symbols. Benjamin Franklin’s “Join, or Die” cartoon used a severed snake to urge colonial unity. Later, the rattlesnake appeared on Revolutionary imagery, including the famous “Don’t Tread on Me” theme. Nothing says “let’s discuss representative government” quite like a venomous reptile with boundary issues.
4. Beavers helped lure empires into North America. The North American fur trade was driven in large part by European demand for beaver pelts, especially for felt hats. This means that a major chapter of colonial history was shaped by diplomacy, commerce, wilderness survival, and Europe’s inability to leave headwear alone.
5. Cod helped build New England. Cod fishing was so important to colonial New England’s economy that Massachusetts eventually honored the fish with the famous “Sacred Cod” in its State House. It is one of those rare moments when politicians unironically acknowledge that something in the State House smells fishy.
6. Horses carried the Revolution. The American Revolution depended on horses for cavalry, couriers, supply movement, reconnaissance, and those dramatic late-night rides that teachers use to keep students awake. Paul Revere gets the poem, but the horse did the legwork, which feels like something the horse’s agent should have negotiated better.
7. George Washington once returned an enemy general’s dog. After the Battle of Germantown, American soldiers found a dog belonging to British General William Howe. Washington returned it under a flag of truce, proving that even during a war for independence, there was still room for basic decency and canine diplomacy. We explored that story in George Washington and the Dogs of War.
8. George Washington’s horses became part of his Revolutionary legend. Washington rode several horses, but Nelson and Blueskin are the two most closely associated with him. Nelson was reportedly steadier under fire, while Blueskin looked magnificent but was harder to manage. In other words, even the Father of His Country had to choose between reliability and photogenic drama.
9. Seaman, Meriwether Lewis’s Newfoundland, joined the Corps of Discovery. Seaman was more than a mascot on the Lewis and Clark Expedition. He hunted, guarded the camp, alerted the party to danger, and generally behaved like the only expedition member who never needed Dr. Rush’s Thunderbolts. Read more about Seaman in Seaman the Dog: Lewis and Clark’s Four-Legged Explorer.
10. A prairie dog made it all the way from the Great Plains to Thomas Jefferson. Lewis and Clark sent a live prairie dog east to President Jefferson, who received it as part of the expedition’s flood of specimens, reports, and “you are not going to believe what we found” discoveries. The little animal helped introduce eastern scientists and politicians to the strange abundance of the American West.

Animals of the Frontier, the West, and America’s Expanding Map

11. The American bison shaped the history of the Plains. For many Native nations, the bison was central to food, clothing, shelter, tools, trade, and spiritual life. The destruction of the bison herds was not merely an ecological catastrophe; it was also part of a devastating assault on Plains cultures. In 2016, the bison became the national mammal of the United States, which is at least an acknowledgment, though the bison would probably have preferred better treatment the first time around.
12. Mustangs became symbols of the American West. Descended largely from horses brought by the Spanish, mustangs became icons of freedom, frontier life, and public-land debates. They are beautiful, stubborn, difficult to manage, and constantly at the center of arguments, which means they may be the most American animal on this list.
13. Mules helped build the West. Mules hauled wagons, supplies, mining equipment, military cargo, and people through places where horses sometimes struggled. They rarely get the glamorous statues, but they did much of the work.
14. The U.S. Army tried using camels in the Southwest. In the 1850s, the Army imported camels to see whether they could handle desert travel better than horses and mules. The camels did well enough, but the Civil War interrupted the experiment, and the animals were eventually sold off or abandoned.
15. A pig nearly started a war between the United States and Britain. The Pig War of 1859 began after an American settler shot a British-owned pig on San Juan Island. Troops arrived, tempers rose, diplomats got involved, and no one was killed except the pig, who remains one of history’s least-appreciated international crisis managers. We covered the Pig War in Tales from the Great and Glorious Pig War of 1859.
16. Seabird eggs caused an armed conflict off the California coast. The Egg War of 1863 erupted on the Farallon Islands, where rival groups fought over the lucrative business of collecting seabird eggs for San Francisco markets. The Gold Rush gave California money, population growth, and the confidence to turn breakfast ingredients into a shooting war.
17. Birds helped launch America’s modern wildlife refuge system. In the late 1800s and early 1900s, egrets and other birds were slaughtered for feathers used in women’s hats. The plume trade helped inspire bird-protection activism and the creation of federal wildlife refuges, beginning with Pelican Island in 1903. For the full fashionable disaster, see The National Wildlife Refuge System and How Fancy Women’s Hats Helped Create It.
18. Old Abe the eagle became a Civil War mascot. Old Abe, a bald eagle, served with the 8th Wisconsin Volunteer Infantry and accompanied the regiment through numerous battles and marches. Soldiers treated him as a symbol of courage, which seems fair, since most birds prefer not to spend their day around artillery.
19. Comanche became one of the most famous horses in U.S. military history. Comanche, Captain Myles Keogh’s horse, was found badly wounded after the Battle of the Little Bighorn and became famous as the only living survivor found from Custer’s five-company command. He was not the only survivor of the entire American force at Little Bighorn, since Reno and Benteen’s commands survived elsewhere on the battlefield.
20. The California grizzly became a state symbol after disappearing from California. The grizzly bear remains on California’s state flag, looking powerful, independent, and very much not present. The last confirmed California grizzlies were gone by the early 20th century. It is a bold state-branding strategy: celebrate the animal after making the place largely unsuitable for it.

Military Animals, Working Animals, and Government Ideas That Sound Like Someone Lost a Bet

21. Sergeant Stubby became one of America’s most famous war dogs. Stubby served with American troops during World War I, warning soldiers of gas attacks, locating wounded men, and becoming a beloved mascot and celebrity. He was not technically filling out leave forms and attending staff meetings, but frankly that probably improved morale.
22. Cher Ami helped save trapped American soldiers in World War I. Cher Ami, a carrier pigeon serving with the U.S. Army Signal Corps, carried a vital message from the “Lost Battalion” despite being wounded. His mission helped prevent American artillery from firing on its own men. We told his story in Cher Ami: The Heroic Pigeon of WWI Who Saved Nearly 200 Lives.
23. Pigeons were once serious military communications technology. Before secure radios became dependable, trained pigeons could carry messages through conditions that defeated wires, runners, and other systems. It is easy to laugh now, but when the alternative is “shout over artillery,” a bird with a tiny backpack starts to look like a defense contractor.
24. Sergeant Reckless carried ammunition in Korea. Reckless, a small Mongolian mare serving with the U.S. Marines during the Korean War, carried ammunition to the front and helped evacuate wounded men. She learned routes so well that she often made trips without a handler. This is impressive and also deeply embarrassing to anyone who still gets lost inside a parking garage.
25. Chips the dog became a World War II hero. Chips, a U.S. Army dog, became famous after breaking away from his handler during the 1943 invasion of Sicily, charging a hidden machine-gun nest, and helping force the surrender of enemy soldiers. He was awarded the Distinguished Service Cross, Silver Star, and Purple Heart, but the honors sparked controversy because military decorations were not supposed to go to animals. The Army eventually allowed Chips to keep his medals while declaring that no more medals would be awarded to dogs. Chips later received posthumous recognition with the PDSA Dickin Medal in 2018, proving that even the military bureaucracy can eventually sit, stay, and do the right thing.
26. Sinbad became the Coast Guard’s four-legged sailor. Sinbad, a mixed-breed dog aboard the Coast Guard cutter Campbell, became a mascot, morale booster, and full-fledged shipmate during World War II. He even had his own service record. Some humans have accomplished less with more résumés.
27. Nemo A534 protected his handler in Vietnam. Nemo, an Air Force sentry dog, was wounded during a Viet Cong attack in 1966 but continued guarding his injured handler. His survival and fame helped draw attention to the role of military working dogs, who were often asked to do dangerous work and then received far less honor than they deserved.
28. The U.S. Navy has trained dolphins and sea lions for military work. Dolphins and sea lions have been trained to locate mines, recover objects, and assist in harbor defense. It sounds like the rejected plot of a Saturday morning cartoon, but it is real. We looked at that and other unlikely animal missions in Spy and Military Animals.
29. The United States seriously considered bat bombs during World War II. Project X-Ray attempted to use bats carrying tiny incendiary devices to start fires in enemy cities. The project was strange, ambitious, and exactly the sort of thing that makes you check whether the adults were out of the room. Read more in Bat Bombs: The Wild WWII Weapon That Almost Changed History.
30. The CIA tried to turn a cat into a spy. Acoustic Kitty was a Cold War project that attempted to outfit a cat with listening equipment and train it for espionage. The program failed for the same reason every cat owner could have predicted for free: the cat had its own priorities. We covered the furry fiasco in Acoustic Kitty: the CIA’s Failed Attempt to Train Cats as Spies.

Presidential Pets, Political Animals, and Creatures Who Wandered Too Close to Power

31. John Quincy Adams supposedly kept an alligator in the White House. The story goes that the alligator was a gift from the Marquis de Lafayette and spent some time in a White House bathroom. Historians approach the details carefully, but the legend endures because “presidential bathroom alligator” is not the sort of phrase civilization can simply discard. For more executive animal weirdness, see Presidential Pets.
32. Abraham Lincoln’s dog Fido became part of the Lincoln legend. Fido stayed behind in Springfield when Lincoln went to Washington, but he remained closely associated with the family’s pre-presidential life. His story later took a darkly ironic turn when he, like Lincoln, died violently. See Abraham Lincoln’s Dog Fido: The Faithful Pet With a Tragic Ending and Abraham Lincoln: Animal Lover-in-Chief.
33. Abraham Lincoln spared a turkey before turkey pardons became a White House tradition. Lincoln’s son Tad reportedly pleaded for the life of a turkey named Jack, who had been intended for Christmas dinner. Lincoln granted the reprieve. It was not yet the modern annual turkey pardon, but it was an early example of presidential clemency being extended to poultry.
34. William Howard Taft kept a cow at the White House. Pauline Wayne supplied milk for the Taft family and became one of the last presidential cows. Today, this feels odd, but at the time it was practical. Before grocery delivery apps, America’s largest president looked at the dairy supply chain and said, “Bring the cow here.”
35. Woodrow Wilson’s sheep grazed the White House lawn during World War I. The sheep saved labor during wartime and their wool was auctioned to raise money for the Red Cross. This is one of the few times in history when sheep contributed more to a national crisis than several committees.
36. Calvin Coolidge’s raccoon Rebecca escaped Thanksgiving dinner and became a pet. Rebecca was sent to the White House as potential holiday food, which was apparently something people did before casseroles became sufficiently complicated. The Coolidges adopted her instead, giving America one of its strangest and most charming First Pets.
37. The teddy bear began with Theodore Roosevelt refusing to shoot a bear. During a 1902 hunting trip in Mississippi, Roosevelt declined to shoot a bear that had been tied up for him. A political cartoon followed, toy makers seized the moment, and “Teddy’s bear” became a national craze. We touched on that story in Part 3 of this series.
38. Lincoln’s horse Old Bob followed him one last time. Old Bob was one of Abraham Lincoln’s horses from his Springfield years, when Lincoln used horses for travel before the presidency turned his commute into a national crisis with paperwork. After Lincoln’s assassination, Old Bob was brought out for the Springfield funeral procession, draped in mourning cloth and led behind Lincoln’s coffin by Rev. Henry Brown. Today, Lincoln and a horse are honored in bronze at President Lincoln’s Cottage in Washington, D.C., where a life-size statue shows Lincoln with his horse, recalling his wartime rides between the Cottage and the White House. Even Lincoln’s horse got a monument. Somewhere, Fido is probably demanding equal statue time.
39. Clay Henry the goat served as mayor of Lajitas, Texas. Lajitas, Texas, became famous for electing a goat named Clay Henry as mayor after a saloon-fueled 1980s political feud turned into an actual campaign. The first Clay Henry eventually won office, became a tourist attraction for his ability to guzzle longneck bottles, and then died in a deeply undignified goat-family scandal involving his son, Clay Henry Jr. The mayoral line later continued with Clay Henry III and Clay Henry IV, making Lajitas possibly the only town in America where “goat mayor” became less of a joke and more of a governing tradition. Democracy is many things, but in Lajitas, it apparently includes hooves, horns, and term limits enforced by barnyard chaos.
40. Trouble the dog inherited millions from Leona Helmsley. When hotel magnate Leona Helmsley died, her Maltese, Trouble, became one of America’s most famous wealthy pets. The trust was later reduced, but the dog still lived better than most of us.

Famous Animals, Disaster Animals, and Conservation Lessons with Fur, Feathers, and Public Relations Problems

41. Balto became a national hero after the 1925 serum run to Nome. Balto led the final team that brought diphtheria antitoxin into Nome, Alaska, during a deadly outbreak. The story became legend, complete with headlines, statues, and cinematic levels of frozen whisker drama. We explored the full story in The Great Race of Mercy.
42. Togo may have deserved more credit than Balto. Balto got the statue, but Togo and musher Leonhard Seppala covered one of the longest and most dangerous portions of the serum run. History often works this way: one dog does the brutal middle miles, another dog arrives for the closing shot, and public relations handles the rest.
43. Owney the dog became the mascot of the Railway Mail Service. Owney rode mail trains across the country in the late 1800s, collecting tags and becoming a beloved postal mascot. He was basically a furry frequent traveler, except he did not complain about legroom or boarding groups.
44. Rin Tin Tin helped save Warner Bros. Rin Tin Tin was rescued from a World War I battlefield and became one of early Hollywood’s biggest animal stars. His films helped Warner Bros. financially during its early years. We included him in our look at the highest-paid dogs in show business.
45. Hollywood animal actors eventually led to serious animal-safety rules. For much of early film history, animal safety was not exactly handled with modern care. Today, the “No Animals Were Harmed” certification rests on a detailed system of rules and oversight. We took a deep dive into those rules in No Animals Were Harmed.
46. Topsy the elephant was electrocuted in a notorious public spectacle. Topsy, a Coney Island elephant, was killed by electrocution in 1903, and the event was filmed by Edison’s company. The story is often tangled up with myths about the “War of the Currents,” but the reality is still grim enough without adding extra mythology. Not every animal in American history got a heroic statue. Some got turned into warnings.
47. Mrs. O’Leary’s cow was blamed for the Great Chicago Fire. The famous story says the cow kicked over a lantern and started the 1871 fire. The evidence is extremely doubtful, and the cow has long since been morally acquitted by anyone not committed to anti-bovine propaganda. We examined the legend in The Great Chicago Fire of 1871: Was Mrs. O’Leary’s Cow the Culprit?.
48. Martha the passenger pigeon became a symbol of extinction. Passenger pigeons once darkened American skies in unimaginable numbers. By 1914, the last known passenger pigeon, Martha, died at the Cincinnati Zoo. Her death became one of the most powerful reminders that “too many to disappear” is not a conservation plan. Read more in The Passenger Pigeon: How the Most Numerous Bird on Earth Became a Memory.
49. Smokey Bear turned one rescued cub into a national fire-prevention icon. The real Smokey was a bear cub rescued from a New Mexico wildfire in 1950. He became the living symbol behind one of the most successful public-service campaigns in American history. We covered the story in Smokey Bear: The Orphan Cub, Wartime Mascot, and Federal Fire Safety Icon Who Told Us Not to Burn Everything Down.
50. Yellowstone wolves became one of America’s most famous wildlife restoration stories. Wolves were reintroduced to Yellowstone in 1995 after decades of absence. Their return affected elk behavior, scavenger patterns, and broader ecological debates. It also reminded Americans that ecosystems are complicated, which is nature’s polite way of saying, “Please stop assuming you understand the whole machine because you found one lever.”

Fun Facts About Animals: One Nation, Under Eagle, With Liberty and Occasional Goat Mayors

Animals have been present at nearly every stage of American history. They carried messages, pulled wagons, fought wars, delivered medicine, inspired toys, helped create conservation laws, appeared on flags, guarded presidents, saved soldiers, starred in movies, and occasionally got blamed for urban disasters they almost certainly did not commit.

They also remind us that history is never just the story of human beings making decisions in rooms. Sometimes the room has a dog under the table. Sometimes the lawn has sheep. Sometimes the battlefield has a pigeon. Sometimes the mayor is a goat.

And sometimes, if we are very fortunate, the animals make the humans look slightly more sensible by comparison.

This brings us to 200 fun facts in our 250-fact celebration of America’s semiquincentennial. That leaves 50 more to go. What do you think the final chapter in this series should cover? If we have learned anything during this series, it is that there is no shortage of fun facts about the USA.
