A hummingbird can stand still, or hover, in the air because its wings move very fast.  When hovering, a hummingbird’s body assumes a nearly vertical position.  Its tiny wings “scull” the air, gaining lift from what is more of a forward-and-backward movement than the more typical up-and-down flapping of other birds.  The hummingbird’s unique wings enable it to remain suspended in midair as it reaches into flowers with its long, slender bill and its even longer tongue, to sip the nectar or to gobble up insects.– Dick Rogers
