What is the Central Idea of the passage?
What's that humming sound?  Could it be hummingbird, the only bird capable of backward flight?  Hummingbirds have many unique flight habits that distinguish them from other birds.  Most birds flap their wings up and down to fly, but the hummingbird moves its wings forward and backward very rapidly in a figure eight pattern.  This allows the hummingbird to hover in position, fly upside down, and move about very rapidly.  And while other birds have to push off with their feet to begin flying, and work their ways up to their top speeds, the hummingbird can both start flying at maximum speed and stop flying instantaneously.  After you've seen a hummingbird in flight, it's unlikely that you'll mistake them for another bird.

• Birds and hummingbirds are very different.
• Hummingbirds make a humming sound.
• Hummingbirds wings fly in figure eight patterns.
• The hummingbird flys in a totally unique and unusual way.
