Yes, baiting for coyotes is legal in NY. Set up at dusk and try to wait them out (boring to me, I can't last more than 2 hours). If you need to pinpoint when they are visiting, set up a trail camera and note what time they are using the bait site. That is when you want to be there. You may want to call at the bait site as well (see Predator Xtreme Oct 08 issue: Bait & Pitch for Coyotes)
