Hummingbirds can fly right, left, up, down backwards,
and even upside down. While other birds get their flight power from
the downstroke only, hummingbirds have strength on the up-stroke as
well. Most hummingbirds flap their wings about 50 or so times a second.
This means all we can see is a blur. The Magnificent Hummingbird is
an exception. Sometimes it flaps it wings slow enough for individual
wing beats to be perceived.
