The use of the word preen to mean the tidying of a bird's feathers dates from Late Middle English. It appears to be a variant of the word prune; one now-obsolete definition of prune meant "anoint", based on the Latin ungere, which had the same meaning.

Why do birds over preen?
Over-Preening
If your bird preens too often, especially when he's not molting, he may end up damaging his feathers. Frayed, broken and missing feathers are signs of over-preening. Stress, anxiety and boredom, as well as health problems, can all cause your bird to preen too much.
