Re: poisoning Starlings ... be aware that it may be a legal means of control in one area but not another. And, what's to keep other birds and critters from ingesting the poison? This is a paragraph from the page Skiekitty linked to:
Legal Status
European starlings are not protected by federal law and in most cases not by state law. Laws vary among states, however, so check with state wildlife officials before beginning a control program. In addition, state or local laws may regulate or prohibit certain control techniques such as shooting or the use of toxicants.
