Ruby Throat Hummingbird Rescue

When a hummingbird flies into an outbuilding or garage, it will not fly down so it typically dies from heat and exhaustion. Most birds achieve lift only when they flap their wings downwards, but hummingbirds can do so on the upstroke too by inverting their wings. Insects achieve a similar feat by inverting their wings at the base, but a hummingbird is constrained by its skeleton, so the mechanism for its maneuver has been unknown until recently.
