Southern front porch philosophy: but don’t shoot a mockingbird

It is rather interesting to essentially confirm, by way of a 100 year old local historian of Monroe county Alabama, that the attitude, thought to not kill a mockingbird or other songbirds – from at least a century ago, at a place in the country where hunted game were eaten – was local to the county, and rather adapted by Harper Lee than created by her. Told to young Southern boys when they got their first gun.

Would seem to me to be an instance of Southern front porch philosophy.
