A male Anna’s hummingbird crosses an 8-centimeter-wide opening, smaller than its 12-centimeter wingspan. Viewed from the side and below, the bird first flies though the hole at a sideways angle in the first clip, fluttering its wings to avoid hitting the barrier. In the second video clip, the hummingbird tucks its wings back against its body as it passes through the hole like a bullet. The clips show each style of flight first at actual speed and then one-twentieth normal speed. Read more: Video: Marc Badger
