you can call and find them 24hrs a day 8 days a week. just a matter of the type of calling you use along with the time of the day. i like to let the animal distress do the job if it's early morning or just before sunset. sheridan was right about the wary "slackers" looking for a meal at sunrise and sunset and animal distress will call them in best IMO. for mid afternoon, they'll be bedding down and sleeping. perfect time to piss one off with a couple howls and challenge barks. if the coyote has a full stomach and is all nuzzled in it's chosen bedding spot, they'll be pissed to hear another stranger coyote walking around in their territory. just don't overdo either calling. keep it fairly simple. for night hunting, i like to stick with quiet distress calling first. if you don't see or hear anything after maybe 20-30mins, try a howler for a few and see if anything answers back. home this was helpful.
