can't walk or hop, but it can zip backward, forward, sideways, and upside
down. It can even hover in mid-air as it sips nectar from flowers! Few
other birds can do any of these things. What's his secret?
A few adaptations help him do this. Unlike other birds, a hummingbird's
wings attach to its body only at its shoulder joints. This enables
the bird to move its wings in all directions and rotate them 180 degrees.
Its large set of flight muscles attached to a large breastbone provide
the "oomph" to do this and more!
Like a Hummer!
your hands out to the side, palms down, and create a "figure
8." Here's how: Bring your hand forward and then up as
you turn your palms up. Make sure your thumbs lead the way.
As your hands go back, down and around, you'll come back to
where you started. Imagine doing this 50 to 80 times a second
as you take a long drink!
a hummer's "upstroke" muscles are as strong as its "downstoke"
muscles, it can hover in mid-air. To do this, it turns its wings over
and back in a figure eight shape.
Did you know that a hummingbird flies with its hands? It has a short,
thick upper bone (like the top of our arms) called a humerus.
But its "handbones" are very long. These support its large
primary feathers and let it quicky move its wings without bending
them. As it flies, its wings beat so fast (about 75 beats per second)
that they sound like they're humming! One Journey North observer said,
"It's very noisy when flying. It almost sounds like a little
propeller plane!" Click here to listen >>.
