howls can be very tricky! i would say a person really needs to study what howls are what before just going out there and throwing out a series of howls! throw out the wrong howl and alot coyotes will not come. 99% of the time they dont run from a baby rabbit screaming. sometimes just making it easy is the best way.
at times coyotes howl all during the day, but not most the time. how many times have you heard a coyote howling besides at daybreak or sunset??? no reason for it if that isnt what they do naturally. this time of year you can stack them up with just simple distress. rabbit will do you fine.
