When birds are attacked or frightened they can drop some of their tail feathers. Lift does exactly what it sounds like; it lifts objects off the ground when everything is just right. 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.
