However, weeks before they migrate, birds fill their bellies with energy-rich foods. In fact, a bird's entire being has adapted to a life of soaring through the air. This is called thrust. The bird reduces its angle of attack and partially folds its wings on the upward stroke so that it passes through the air with the least possible resistance. One of the most unique flying animals is Wallaces flying frog, which uses an incredibly unusual method to stay in the air. If you want to play in the hawkwatching arena, you're going to have to rethink your concept of a field mark. So smaller-winged birds (and planes) need to fly faster to maintain the same lift as those with larger wings. Also, when they sleep or rest, the birds tuck their bills under their wing feathers in order to breathe in this warmer air. Getting the air to move over and under the wing also requires the wing to be moving. Birds such as the Anhingas lose heat rapidly from their bodies, so by spreading their wings and turning their backs on the sun, they can absorb solar energy to heat themselves. Others may use a running take-off from the ground. This means the air is moving more quickly over the top surface of the wing, reducing air pressure on the top of the wing and creating lift. More brightly-colored birds may also find mates more easily. The power for this comes when the massive chest muscles pull the wings down. feathers that spread out, creating slots that allow the bird to catch vertical columns of hot air called thermals and rise higher in the air.
