Sign in to continue reading. This means the air is moving more quickly over the top surface of the wing, reducing air pressure on the top of the wing and creating lift. In terms of aerodynamics, there are four forces that greatly influence bird flight. A birds wing produces lift and thrust during the downstroke. A hummingbird can fly up to 60 miles per hour in a steep courtship dive, but speeds of 20-45 miles per hour are more common in straight, steady flight.
