Down here(Florida) gracckle heads are black/ dark purple/ mallard duck neck green. Well, theyre black, that's the head's color. Today I saw a squirrel lifting it's leg to urinate like a male dog. And when I shot at it a grackle flew up from the othe side of my yard. I hit the squirrel but it was a tiny rock so it didnt kill it. My main supply of rocks is from my neighbor's pond and I haven't jumped the fence in a while. I need to get to Wal-Mart to get some ammo. Or BPS I'm going there this weekend to shoot my bow.
