Hi Robert,,,,,
Here is a passage I copied directly from the New York State Environmental Conservation Law that I believe will answer your question concerning the status of Common Grackles in New York State....................
"Small Game and Furbearer Seasons and Regulations
Protected Wildlife:
In New York State, nearly all species of wildlife are protected. Most species, including endangered species, songbirds, hawks and owls are fully protected and may not be taken. The few unprotected species include porcupine, red squirrel, woodchuck, English sparrow, starling, rock pigeon, and monk parakeet. Unprotected species may be taken at any time without limit. A hunting license is required to hunt unprotected wildlife with a bow or firearm."
So as you can see in NY State the Common Grackle is not legally considered an "unprotected species" and is therefore afforded legal protection under the law. There is however one exception,,,,,,,,, the Environmental Conservation Law does allow the Common Grackle to be killed during the months of June, July, August, September and October by any crop owner, any employees of the crop owner actively employed in the tending of said crops or by the owner of the land on which the crops are growing,,, provided it can be shown that the Grackles are in fact destroying or damaging the crop.
I'm not posting this to get involved with who shoots grackles and who doesn't, I only concern myself with the critters that I hunt and shoot,,,, it's just that you asked a question about the laws in New York regarding Grackles and I happen to know the answer since part of my occupation involves these laws.
