Crab Facts: Claws, Shells & Secret Behaviors
Crabs are crustaceans found on every continent with over 7,000 species. Discover why crabs walk sideways, trade shells, and grow claws stronger than jaws.

Pigeons are intelligent birds with remarkable navigation abilities that served as war heroes saving thousands of lives. Discover pigeon history, myths debunked, and surprising intelligence.
Pigeons rank among the most misunderstood animals despite serving as war heroes saving thousands of soldiers' lives. These intelligent birds navigate across hundreds of miles home, recognize all twenty six letters of the alphabet, and distinguish paintings by Monet versus Picasso.
Pigeons suffer from an unfair reputation as dirty disease carriers, but scientific evidence contradicts this stereotype. Research shows pigeons carry fewer diseases transmissible to humans than most urban animals including rats, mice, and even pets. The "rats with wings" phrase coined in a 1960s propaganda campaign successfully demonized pigeons despite lacking scientific basis.
Over 100,000 pigeons served in World War I with ninety five percent success rates. In October 1918, 194 American soldiers trapped behind enemy lines faced friendly fire from Allied artillery. GI Joe prevented a bombing that would have killed over 1,000 British troops in Italy, flying twenty miles in twenty minutes.
Pigeons possess extraordinary navigation abilities scientists still cannot fully explain. Homing pigeons return from locations up to 1,000 miles away at sustained speeds of fifty to sixty mph. They see ultraviolet light and polarized light patterns invisible to humans.
Pigeons demonstrate intelligence often overlooked due to their common status. Shown works by Monet and Picasso, pigeons categorize each artist's style and apply this knowledge to paintings they have never seen. Pigeons pass mirror self recognition tests showing self awareness found only in great apes, dolphins, and elephants.
Pigeons represent one of the earliest birds domesticated by humans, beginning 5,000 to 10,000 years ago in the Middle East. By 3000 BC, Egyptians kept large pigeon houses. Selective breeding created over 300 fancy pigeon varieties.
City pigeons descended from domestic birds bred by humans, not wild invaders. They are feral domestic animals like stray cats. Their wild ancestor is the rock dove.
Pigeons were among the first birds domesticated by humans, beginning 5,000 to 10,000 years ago.

Pigeon racing remains a popular sport with devoted enthusiasts globally.
War pigeon monuments honor their service in multiple countries.
Before the 1960s propaganda campaign, pigeons were widely respected as intelligent, loyal birds. They served as critical military messengers, racing champions, and symbols of peace. Ancient civilizations revered them, and their domestication predated most other birds.
After the 'rats with wings' campaign successfully rebranded pigeons as pests, public perception shifted dramatically despite lacking scientific basis. Urban pigeons faced extermination efforts and negative stereotypes. However, recent research documenting their intelligence and the propaganda origins has begun restoring appreciation for these historically valued birds.

They saved thousands of soldiers. War pigeons delivered over 100,000 critical messages with 95 percent success rates.
Rats with wings is propaganda. The phrase came from 1960s building owners, not science. Pigeons carry fewer diseases than rats.
They recognize Monet from Picasso. Pigeons can categorize paintings by different artists and apply knowledge to unseen works.
City pigeons are not wild. They descend from domesticated birds, making them feral like stray cats.
They navigate 1,000 miles home. Pigeons use magnetoreception, sun position, landmarks, and possibly smell simultaneously.
32 received military medals. More pigeons won the Dickin Medal for gallantry in WWII than any other animal.
No, pigeons are not particularly dirty or disease ridden. Research shows they carry fewer diseases transmissible to humans than rats, mice, and many pets. Pigeons groom constantly and possess antibacterial feathers. Disease transmission to humans is extremely rare. The dirty reputation stems from 1960s propaganda, not science.
