Thanks, @August West. If you are able to find and post a link to what NC defines as songbirds/not songbirds, I'll include a link to that in my summary.NORTH CAROLINA
LEGAL FOR NON-GAME SPECIES
Per e-mail conversation with DNR:
DNR: "There are no relevant regulations because a slingshot is not a legal weapon to take game in the state of North Carolina."
ME: "Thank you. Does this mean that non-game "nuisance" species, such as rats, starlings, European house sparrows, etc. also may not be taken with a slingshot?"
DNR: "Rats are not game animals so it probably is not against the law to use a slingshot to kill them. In North Carolina it is against the law to kill songbirds of any kind including starlings and sparrows."
The use of the word "probably" by the DNR representative scares me.
Whoever emailed you does not know what he is talking about. English Sparrows and Starlings are not considered song birds and may be shot on sight.
