African Gray Parrot

One day, the African Gray Parrot came across a deadly batch of radiation. The bird was infected and layed corrupted eggs. Generations later, the environment has changed to a desert area with an abundance of dumbbells that the military dropped to keep the birds busy. Over generations, the birds' wings turn into arms and they get shorter and wider from lifting weights. Generally, their social hierarchy is similar to goats; the bird with the biggest lats and biceps gets to mate first.
