During the Cold War, American intelligence agencies used some pretty unusual tools to gather information on the Soviet Union. While high-tech gadgets like the Tecina camera, which could fit inside a cigarette box, and the massive Big Bird spy satellite were impressive, one of the most surprising tools was the humble pigeon.
Pigeons have an amazing ability to find their way home from hundreds of miles away, making them perfect for espionage. In the 1970s, the CIA took advantage of this by attaching tiny cameras to pigeons in a secret operation called Takana. These cameras automatically snapped pictures as the pigeons flew, capturing images that were often more detailed than those taken by satellites, since pigeons fly much closer to the ground.
The tricky part was figuring out how to release these spy pigeons without being noticed. Creative methods included letting them go from inside a trench coat, through a hole in a parked car, or even out of a car window while driving at 50 miles per hour. The exact number of pigeons used for intelligence during the Cold War is still a mystery, as many documents remain classified.
Pigeons have been trusted for their navigation skills for thousands of years. Despite some misconceptions, pigeons are real animals with a natural range that includes Europe, North Africa, and Asia. In captivity, they can live over 15 years and fly up to 700 miles in a day at speeds of 90 miles per hour. These traits have made them valuable to humans throughout history.
In ancient Egypt, pigeons were used to announce the arrival of important visitors. In 2350 BC, King Sargon of Akkad used pigeons to send messages if his messengers were captured. Throughout the Middle Ages, pigeons were the fastest way to send mail until the telegraph was invented. Even after new communication technologies emerged, pigeons played crucial roles in military operations.
During World War I, pigeons delivered messages when telegraph wires were at risk of being cut. In World War II, the British used nearly 250,000 pigeons across their defense services. They even trained birds of prey to avoid attacking these pigeons. British intelligence dropped pigeons over occupied Europe with questionnaires, allowing resistance fighters to send back valuable information. One pigeon even returned with a 12-page report for Winston Churchill.
Pigeons were so important during the war that they received medals for their service. The Dickin Medal, awarded for bravery, was given to 53 animals during World War II, with 32 going to pigeons, including the American bird G.I. Joe.
Training pigeons for military use was straightforward. If pigeons are raised in a specific loft and gradually taken farther away, they learn to return home from almost any location. Intelligence services used this to release pigeons over targets of interest.
Scientists have long been fascinated by how pigeons navigate so well. Some believe pigeons use the sun as a compass, while others think they rely on major landmarks. Another theory suggests pigeons use the Earth’s magnetic fields, possibly sensing them with tiny particles of magnetite in their beaks.
Some researchers propose that a pigeon’s sense of smell is crucial for navigation. Studies show that pigeons with impaired olfactory senses struggle to find their way home. Recent research suggests pigeons might create mental maps based on smells.
Despite their skills, pigeons can still get lost, a phenomenon known as release site bias. Researcher John Hagstrom found that pigeons might use sounds to navigate. He discovered that geography at certain sites prevented pigeons from hearing infrasounds that could guide them home. When atmospheric conditions changed, allowing the sounds to be heard, the pigeons successfully returned.
While pigeons aren’t perfect navigators, their abilities have been respected for centuries. Often seen as urban nuisances today, pigeons have played significant roles in saving lives, especially during World War II. For example, G.I. Joe, a pigeon, delivered a crucial message that prevented an air attack, saving many lives.
In warfare, communication is key. The Allies’ ability to transmit and interpret information was crucial in winning World War II. The Battle of Britain, the first entirely aerial battle, highlights the importance of effective communication. For more on this topic, you can explore the series “Battle of Britain” on Nebula, produced by Real Engineering, which delves into the communication innovations during the war.

Throughout the Cold War, American intelligence agencies employed a variety of unconventional tools to spy on the Soviet Union, ranging from large to small. One notable device was the Tecina camera, which could fit into a cigarette box, allowing it to be discreetly brought into meetings. A fake silver dollar served as a hiding space for small secret documents, while the giant spy satellite known as Big Bird captured images of the USSR from space. However, perhaps the most unconventional tool of the Cold War was not a high-tech device, but rather a common animal: the pigeon.
Pigeons were invaluable assets for espionage due to their remarkable homing ability, which enables them to navigate back to a specific location from hundreds of miles away. In the 1970s, the CIA harnessed this navigational instinct by attaching miniature cameras to spy pigeons in an operation known as Takana, which remained classified until 2019. These battery-operated cameras took pictures automatically at set intervals as the pigeons flew, and the pigeons could capture around 140 images. In trial runs, about half of the photos were of good quality, often providing more detail than satellites or reconnaissance planes, as pigeons fly much closer to the ground.
The challenge was finding ways to release the spy pigeons behind enemy lines without detection. Methods included releasing the birds from inside a trench coat, through a hole in the floor of a parked car, and even from the window of a car traveling at 50 miles per hour. The exact number of pigeons that provided intelligence during the Cold War remains unknown, as those documents are still classified.
Pigeons have an incredible sense of direction, a trait humans have relied on for millennia. Despite common misconceptions, pigeons are indeed real animals. While the common pigeon is now a familiar sight worldwide, its native range includes Europe, North Africa, and Asia. In captivity, they can live for over 15 years and can fly as far as 700 miles in a day, reaching speeds of up to 90 miles per hour. These qualities have made pigeons highly valuable to humans throughout history.
In ancient Egypt, pigeons were released from incoming ships to announce the arrival of important visitors. In 2350 BC, King Sargon of Akkad had his messengers carry homing pigeons to alert the government if they were captured. Pigeons served as a mail service throughout the Middle Ages and were the fastest couriers available until the invention of the telegraph. Even after new communication technologies emerged, pigeons retained a significant role in military operations.
During World War I, both sides used pigeons to deliver messages, as telegraph wires were vulnerable to attack. In World War II, the British employed nearly a quarter of a million pigeons across various branches of the defense services. Birds of prey along the coast were even trained to avoid attacking the pigeons. British intelligence operated a secret pigeon service, dropping thousands of birds over occupied Europe with questionnaires attached to their legs. Those working with the resistance against Nazi Germany could then return the pigeons with valuable information about German radar stations, rocket launch sites, and troop movements. One pigeon even returned with a 12-page intelligence report addressed to Winston Churchill.
Pigeons were so valuable during the war effort that they received medals for their service. Throughout World War II, the Dickin Medal was awarded to 53 animals for displaying conspicuous gallantry and devotion to duty, with 32 of those medals going to pigeons, including the American bird G.I. Joe.
During the Cold War, spy pigeons were released in Moscow to gather intelligence on priority targets within the Soviet Union. A 1976 report indicated that the shipyards at Leningrad, where the Soviet Union built advanced submarines, were a key target. Unfortunately, the secrets the pigeons may have uncovered remain classified.
The military’s training process for these pigeons was relatively straightforward. If pigeons are raised in a specific loft—a building where they spend their early weeks without leaving—and then gradually taken farther away, they naturally learn to navigate back to the loft from almost any location, even when hundreds of miles away. Intelligence services could then release pigeons in locations where they would cross over targets of interest.
Scientists have long sought to understand how pigeons navigate so effectively. Some researchers proposed that pigeons use a solar compass, relying on the sun’s position relative to their loft. Experiments have shown that pigeons do use the sun as part of their navigational system, but it is not the only factor. Pigeons also seem to develop routes based on major landmarks, although their vision is not the sole determinant of their navigation.
Another hypothesis suggests that pigeons use the Earth’s magnetic fields for navigation. The planet’s molten metallic outer core generates electric currents, creating a magnetic shield around the Earth. Experiments indicated that pigeons might have tiny particles of magnetite in their beaks, allowing them to sense magnetic fields.
Additionally, some researchers believe that a pigeon’s sense of smell plays a crucial role in navigation. Studies have shown that pigeons with impaired olfactory senses struggle to find their way home, while those that can detect magnetic fields generally do not. Recent research has mapped airborne volatile organic compounds around a pigeon’s home, suggesting that they may create a mental map based on smells.
Despite their impressive navigational abilities, pigeons can still get lost, a phenomenon known as release site bias. One researcher, John Hagstrom, investigated this issue and proposed that pigeons might use sounds to navigate. He created an acoustic map of various release sites and discovered that the geography of one site prevented pigeons from hearing the infrasounds that could guide them home. The only time the birds successfully returned from that site was when atmospheric conditions changed, allowing them to hear the sounds.
While pigeons may not be perfect navigators from every location, their abilities have been respected and utilized by humans for centuries. Despite being seen as urban nuisances, pigeons have played significant roles in saving lives, particularly during World War II. One notable example is G.I. Joe, a pigeon that delivered a crucial message to call off an impending air attack, saving the lives of at least 100 soldiers and countless civilians.
In the context of warfare, communication is vital. World War II was largely won due to the Allies’ superior ability to transmit and interpret constantly changing information. The Battle of Britain, the first battle fought entirely in the air, exemplifies the importance of effective communication. For more on this topic, you can explore the series “Battle of Britain” exclusively on Nebula, produced by our partner channel Real Engineering. The series delves into the invention of the doubting system, which revolutionized communication operations during the war.
