To some extent, bats are the ultimate LBJs. Probably a brown bat; they're the most widespread. (Remember, I used to live in Austin, which is Bat Central; one can't help but acquire a little bat knowledge if one lives only half a mile from THE Bat Bridge.)
And throwing mealworms (fresh or freeze-dried, depending on one's level of squeamishness, which you probably have very little of) also works...
