As the feather sheaths break open exposing the true feathers, the young swifts preen continuosly to condition the new plumage. Tiny bits of the discarded sheath can be seen floating free in the tower. The last sheaths to break open are those on the head and face of the babies -- giving them a "frosty-faced" appearance.
