Although there are plenty of flightless bird species on Earth, the Parlor Roller pigeon is believed to be the only one selectively bred by humans until it lost its capacity to take to the skies and developed a completely new and bizarre means of getting around – backflips.
Seeing a parlor roller pigeon roll on the ground, you would think it was having some sort of seizure, but in reality, the birds are rolling on the ground because it comes naturally to them. No one knows exactly how or when the breed was created, but experts and enthusiasts speculate that its origins can be traced back to mid-19th century Scotland when someone probably encountered a specimen with a slight tendency to roll on the ground and decided it was worth emphasizing via selective breeding. It is believed that over years of selective breeding, pigeons that rolled over long distances were obtained.
