Telephone wires: Pigeons. Parking lots: Pigeons. Building ledges: Pigeons. Why do so many cities have flocks and flocks of pigeons?
How did these hardy birds become one of the most abundant species on the planet? Learn how pigeons took over the world with this TED-Ed lesson by evolutionary biologist Dr. Elizabeth Carlen and Doctorate of Veterinary Medicine student Joanna Moles:
“Seeing their meat as a protein source and their nitrogen-rich poop as the perfect fertilizer, humans brought pigeons into captivity as far back as 10,000 years ago. We then tapped into other traits. Pigeons are naturally speedy and possess a powerful homing instinct that drives them to navigate long distances back to the location they consider “home.” So we began developing pigeon posts and breeding and training them for racing. In a hobby called “pigeon fancying,” people selected for traits like head plumage and fabulously feathered feet.”
“As we carried pigeons around the world, they escaped or were released, forming the wild urban flocks we’re familiar with today. Pigeons are now one of the most abundant, widespread species on the planet, managing to thrive in chaotic cities.”
