I've called them at all parts of the day, but probably have better luck in the morning, but that may be I have hunted more in the mornings. If they are hungry or in the mood, they can be called. If not hungry or in the mood, they will stay napping and ignore you.
@Jagermeister. Agree with this. They can be killed all times of the day. What is best? It fluctuates so much, not sure why, maybe time of year. I don’t keep track of any data, but for awhile I was having great luck from 9-11, and then for while I had better luck in the evenings, but lately I’ve had better luck in the mornings, so I think the short answer is anytime. Middle of the day, I believe to be better in the timber. They are likely sleeping, but definitely chilling and not hunting. You get in the timber with them and light up a howl 150 yards away, you’re gonna piss them off and they’ll come to fight you. Like I mentioned before, check out the mfk videos. I don’t like to let them ignore me. Every coyote will have a trigger, you just have to find it. Food, fock, or fight. He may not be hungry and might not be horny, but he’s still territorial and so is she and if you get into an alpha pair, and you get a little aggressive with your vocals, you’ll probably get at least one interested and if one comes, a lot of times, you’ll get the whole group.
@BC-Buck, when you say you can’t get them to cross a field, are you seeing them stop at the edge, are you hearing them, like they are answering you but don’t come. Basically how do you know you can’t get them to cross? They can be finicky, especially with decoys. If they’ve gotten shot at and missed with a decoy and they see that decoy out in the field, they won’t come to it. I think I had this happen a couple weeks ago. I called one to the edge of the field and he sat and watched. I strongly believe there were other coyotes with him still in the timber. There were turkeys that I saw go into the timber just prior to my set. 20 minutes later I heard a weird Turkey sound which now I’m convinced was a coyote going after it. At 22 minutes, I saw the coyote sitting at 325 yards, all I could see was head and ears. I would have had to move a fair amount to get the shot so opted to wait him out and see what he’d do. He kept looking to the caller and looking back, over and over. I played several different sounds to get him to come, but he sat there for 7 minutes deciding what to do before turning and going back to the timber. I’m pretty sure the decoy freaked him out and he’s probably see a decoy and possibly mine before. But I’ve killed way more dogs within 20 yards of the decoy, so I’ll probably continue using it, just not on that particular set. If you don’t use a decoy, try adding it and seeing if it helps them to commit.
