Hunted yesterday morning. Three locations. No dice. Did three sets this morning. One this evening 545-730pm with no luck. Showed a house. Checked some parking lots for ice. Just finished another set on my property. Nothing. I have tried every mix of calls I know. Evenings I try to start with a distress a couple minutes, cut straight to coyote locator. Sit and listen. If nothing, I go for some female howls, female invitation, and throw in a male challenge bark here and there. I am stumped. I know they are in the area because I cut two sets of tracks this morning. A set each on two different properties. Best I can figure is they were running their loops last night after it stopped snowing. They may have "been" in the area last night, but that doesn't mean they weren't 2-3 miles away this morning when I was calling. Oh well. I will be persistent now because I don't like to lose. I will get one yet. It is February. Prime time!
