The wing is made flat on the bottom and curved on the top. The air underneath has a shorter distance to go to get to the end of the wing, that is straight so. The air over the top has further to go because of the curve so the air travels faster. This causes 'low preasure' above the wing. This makes the air around the wing rush in and 'sucks' the wing up causeing lift.
The exact same thing happens on a bird wing except they do not have engines to push them forward. So the bird flaps its wing to push the air behind them and down which gives them lift and pushes them through the air.

Why don't birds flap their wings sometimes?
Birds ride thermals, as you would if you took a balloon ride. This saves energy. Imagine the hummingbird, who flies 3000 miles one way during migration. It takes too long to stop and eat all the time, so they ride the thermals. Different sizes and shapes of birds allow for differences in the way they fly. These differences are also helpful in identifying birds in the field. For example, ducks flap their wings very quickly, geese at a steady pace, and pelicans flap a few times and then glide for a few seconds. Generally, birds with larger wings do not have to flap as often but do not fly as quickly as birds with smaller wings.
