Narrative:

After liftoff from ZZZ we received one aural stall warning followed by continuous stick shaker. Returned for a VFR landing at ZZZ without declaring an emergency and without incident. At the gate, the mechanics found the stall vane on the captain's side bent back. I don't know when it was damaged. It could have been when the jetbridge was moved for departure or before, or it is possible we hit a bird or something like that. The flight eventually canceled due to lack of parts.
