When we think about fascinating creatures on Earth, pigeons might not be the first to come to mind. However, these birds are more interesting than you might think. Let’s dive into the world of pigeons and discover why they are so special.
Charles Darwin, the famous scientist who introduced the theory of evolution, thought pigeons were pretty important. In his book “On the Origin of Species,” he used pigeons as an example to explain his ideas. Why pigeons? Because they show how much a species can change over time. Just like dogs come in many shapes and sizes, pigeons have been bred into various forms from their wild ancestor, the rock dove.
Before pigeons became city dwellers, they lived on seaside cliffs. When cities were built, pigeons moved in because buildings seemed like cliffs to them. People liked having pigeons around and often fed them. Over time, some pigeons escaped and adapted to city life, becoming the pigeons we see today.
You might not think pigeons are smart, but they have some surprising abilities. Their brains might be small, but their eyes are huge compared to their size. Pigeons can see more colors than humans, thanks to their five color receptors. They can remember up to a thousand images, tell the difference between different art styles, and even recognize correctly spelled words.
During World War II, a psychologist named B.F. Skinner tried to train pigeons to help guide bombs. Although the project didn’t succeed, it showed how pigeons could be trained to do complex tasks. Pigeons have also been used as messengers for centuries. They have an incredible ability to find their way home, using visual maps, the Earth’s magnetic field, the sun, and even smells.
Have you ever wondered why you never see baby pigeons? They do exist, but they stay in their nests until they’re big enough to fly. This is why we mostly see adult pigeons around.
Pigeons are everywhere, but there’s so much more to them than meets the eye. They played a role in Darwin’s groundbreaking ideas about evolution and continue to amaze us with their intelligence and adaptability. Next time you see a pigeon, take a moment to appreciate this remarkable bird. And remember, wildlife is all around us, so stay curious and keep exploring!
For more amazing stories about urban wildlife, check out the BBC series “Planet Earth II,” which features pigeons and their interactions with predators like peregrine falcons. You can find more information on their website.
Create a poster that illustrates the evolution of pigeons from their wild ancestor, the rock dove, to the various breeds we see today. Use images and descriptions to show how selective breeding has changed their appearance over time. Present your poster to the class and explain the connection to Charles Darwin’s theory of evolution.
Take a walk around your neighborhood or a local park to observe pigeons in their urban habitat. Note where they gather, what they eat, and how they interact with their environment. Write a short report on how pigeons have adapted to city life and compare it to their natural cliff-dwelling behavior.
Conduct a simple experiment to test pigeon intelligence. Create a puzzle or maze using cardboard and see if pigeons can find their way to a small food reward. Record your observations and discuss what this reveals about their problem-solving abilities and memory.
Research a historical event where pigeons played a significant role, such as during World War II. In groups, create a short skit or role-play to demonstrate how pigeons were used as messengers or in other capacities. Present your skit to the class and discuss the impact pigeons had on communication and warfare.
Investigate why baby pigeons are rarely seen. Research their nesting habits and development stages. Create a presentation or infographic that explains where baby pigeons are typically found and how they grow into the adult pigeons we commonly see.
Here’s a sanitized version of the transcript:

Human history is intertwined with some of Earth’s remarkable species, but there is one graceful creature that stands out. Only when seen in its ideal habitat can we truly appreciate this king among birds. Behold: the noble pigeon. If you think they’re only known for being a nuisance, then think again.
In “On the Origin of Species,” Charles Darwin presented an idea that changed the world. He knew if he was right, this idea would turn science on its head, so in chapter 1, he chose pigeons as his very first example. Over giant fossil armadillos. He had a good reason, and if you think otherwise, then you’ve never seen fancy pigeons. These are the birds that caught Darwin’s attention because underneath all that feathery fashion is just one species, like dogs with wings instead of rats with wings. All of that variation was derived from one ancient mold: the wild rock dove.
Thousands of years before they were scavenging in urban areas, these birds were found on seaside cliffs. But as soon as cities emerged, they moved in, because to a pigeon, a building is just a cliff with better architecture. Pigeons are uniquely suited to city life, but they were only able to thrive in urban areas because we brought them there. Why? Because we liked feeding them. In fact, from Egypt to Rome to the early 20th century, the main roles of a pigeon were as a food source or as pets for people who bred them into various shapes.
Over time, a few of these domestic birds escaped and returned to a “wild” life, but they never left the city. However, our perception of pigeons changed significantly along that journey. Watch pigeons pecking at the sidewalk, and you might not think they’re the smartest birds. They can’t solve puzzles like crows or mimic speech like parrots. A pigeon’s brain is only about the size of a fingertip, but like most things in nature, there’s more to the story. Most of their skull is taken up by their eyes: if they were the size of humans, their eyes would be as big as grapefruits. Those large eyes have five color receptors compared to our three, allowing them to see things we can’t even imagine.
One pigeon named Linus was trained to remember nearly a thousand images. Pigeons can distinguish between a Monet and a Picasso, and they can even evaluate the quality of a child’s drawing. They can identify correctly spelled words among misspelled ones. They can also arrange groups of objects in numerical order, which may seem simple to us, but pigeons have a remarkable ability to understand numbers.
During World War II, psychologist B.F. Skinner attempted to train pigeons to assist in navigation for bombs. He trained them to keep an image centered on a tiny screen by pecking at it, connecting this to a navigation system. He envisioned creating explosive missiles guided by pigeons, and he built several prototypes with funding from a cereal company, but the project never took off.
Pigeon navigation extends beyond these experiments. Like human city-dwellers, pigeons are commuters, flying out in the morning to find food and returning at night. They are strongly bonded to their homes, and this instinct has led us to use them as messengers for centuries. Before Paul Reuter founded a global news service, he used pigeons to deliver news. During World Wars I and II, racing pigeons with names like Cher Ami and GI Joe were awarded medals for delivering messages under fire.
How are pigeons so adept at finding their way home from unfamiliar places? Various experiments have shown that pigeons use visual maps, Earth’s magnetic field, the angle of the sun, and even scents to navigate. However, when scientists disrupt these senses, some pigeons can still find their way home. What we do know is that pigeons utilize multiple senses, possibly even some we have yet to discover.
Even though pigeons are ubiquitous, there’s one thing you rarely see: baby pigeons. They do exist, and they are not particularly attractive. But this serves as a reminder that even a bird that is everywhere only gives us glimpses into its life. Darwin’s ideas about natural selection were born on a voyage around the world, but you don’t have to travel to exotic places to appreciate evolution’s wonders. Darwin understood this, which is why he chose the pigeon to introduce the world to his theory. If you know where to look, wildlife is all around us; just make sure to keep your mouth closed if you look up to admire it. Stay curious.
I want to thank our friends from BBC Earth for helping us create this episode, as pigeons look amazing in slow motion. Some of pigeons’ oldest enemies have followed them into cities: birds of prey. Scientists are studying peregrine falcons for “Planet Earth II,” the sequel to the groundbreaking BBC series. It’s part of an entire episode dedicated to urban wildlife. Of course, birds of prey aren’t the only urban predators of pigeons. For “Planet Earth II,” the team filmed a pigeon hunt that you have to see to believe. You can find “Planet Earth II” on BBC One in the UK and coming soon to BBC America. For more information, check out their website.
