Common Redshank (Tringa totanus) in flight, using its alula (bastard wing, or winglet) to slow it down without risking stalling in preparation for landing, Djupivogur, Austurland (Eastern Region, East Iceland), Iceland
The alula is the equivalent of our thumb, is freely movable, and usually bears between 3 and 5 small flight feathers. Normally the alula is held flush against the wing, but when flying slowly or landing, the bird moves it slightly upwards and forwards, creating a small slot on the wing's leading edge. This allows the wing to achieve a greater than normal angle of attack – and thus lift – without resulting in a stall.
