It's amazing how many people I meet who think "prepping" is buying that overpriced freeze dried crap.  I tell them they're great if you're climbing Mt. Everest.  Otherwise, I'll take that can of Dinty Moore Beef Stew and a bag of wheat and sourdough starter.
I once fed my neighbor a sparrow sandwich, and she liked it (until I told her what the filling was).  Sparrows and starlings are everywhere, and it doesn't take a genius to learn how to trap them.  Not a lot of meat on them, but when you have a dozen of them, it'll work.  Best of all, there are no restrictions on how many of them you can catch.  ( But check your local laws, just in case.)

Now you know the reason for the English saying of "Four and 20 Blackbirds baked in a Pie".  Meat pies are very big in England even today.  They are mostly Pork or Steak and Kidney now though.  In living there threer yearsI could never find a Black Bird one, but they damm sure had enough of them flying everywhere there.
