If the object (airplane / bird) maintains a slightly negative angle of attack, it can make part of the lifting force contribute to boost by countering the resistance. On the average that the remaining lift is not much less than the force of gravity, the object is long maintained in the air. You can talk about an extremely slow controlled descent or glide.
