If you are truely letting them fly, you will see them increase their wing's angle of attack, slow down, and "flare" before landing.

Not only that, they slide extend their alula forward which is like a leading edge slat to preserve air flow at slower speed. You can see it in the photo above the orange on the wing. Those feathers sticking up are acting as a leading edge slat. It is really quite amazing. I've done a lecture comparing airplanes to birds, you can check it out here if you find this sort of stuff interesting.
