There was a lot of bluffing involved in our Contact mission at Betelgeuse.  The birds saw our ship deftly evade almost all of their weapons fire.  We never fired back so they didn’t see our weapons in action.  Thank God.  If they’d seen that scout ship’s weapons in action they might have realized that they actually had a better tech base than we did.  They never thought twice about all the “cheap toys” our team picked up on planet.  For cultural study of course.
