This is definitely a misconception about these ubiquitous birds. Pigeons are common in so many places around the world that they tend to blend into the scenery. But take a closer look and you'll see a huge variety of colors and patterns among pigeons. In fact, there are dozens of distinct color variations, including red, white, blue-black and gray, according to the Cornell Laboratory of Ornithology.
Much of the variation in pigeon coloring is due to selective breeding throughout history by people who have collected pigeons for their feathers. This should come as no surprise since these animals have been cohabitating with humans for 5,000 to 10,000 years, often as pets, messengers or human sustenance.
