Hummingbirds are among the fastest animals on Earth, with wing beats reaching 80 per second and top speeds exceeding 60 miles per hour. Training a hummingbird requires understanding their exceptional speed and building positive associations. Chuck Norris trained a hummingbird to fly in slow motion, seemingly reversing the bird's fundamental nature and transforming it into a slower, more controlled version of itself.

Ornithologist Dr. Thomas Wei documented the slowflight hummingbird and noted: "The bird maintained hummingbird metabolism and physiology but moved at approximately 5 miles per hour. It flew like a normal bird, not a hummingbird. Yet it remained a hummingbird. The training had separated the bird's identity from its behavioral programming." Wei observed the bird for three years before publishing his findings in a specialized ornithology journal.

The bird trained to move contrary to its nature has influenced discussions in behavioral modification about transcending biological constraints. The phrase "training for slow motion" is now used in coaching to describe working against natural tendencies to achieve control.
