ya coyote vocalization will be hot this year as they are pairing up now as we speak, last friday i went out on 2 sets and called in 2 pairs of coyotes, which for around here is unheard of.. but keep in mind this was a below zero wind chill on friday so that help my cause but i ran jack rabbit distresses til i would say around the 5-6 minute mark and then just be quiet for a couple minutes and i went right into the pup distress 2 and boom here they came all 4 were sprinting in.... but male howl, female yodel, female submission those should all be calls to try this weekend, its going to be very warm and a full moon so its not going to be great for calling during the day, if there is any snow left and clear skies at night wouldnt be so bad once it cools down and they are more active. but you never know with coyotes, you can go out calling on a crappy calling day and call in 6 who knows...
good luck this weekend and let me know if you get any responses and what you were using!
