Researchers have attributed mutations in Pigeons to a variety of genetic insufficiencies that many scientists still don’t completely understand.

Sometimes, Rock pigeons, English Trumpeter pigeons, and English Pouter pigeons experience mutations in their color, heads, and torsos due to complications involving the EphB2 gene. A video of a mutated English Pouter pigeon recently went viral, causing debate amongst viewers about the validity of the footage. Because although these birds typically grow to 16 inches in height, the legs and feet depicted in this video are extremely abnormal, leading some to believe that the clip was AI-generated.

The video has been covered by several major media outlets and some have even declared that the footage is real.
