The aggressive howl is a quicker howl that starts fast and ends abruptly. The quicker it starts and the faster it ends, the more aggressive the sound and the more upset the coyote. This is the sound that we’re all too familiar with. We all have had a female “dawg” stand there for 5 or 10 minutes and tell the world just what she thinks of us. Those barks and quick howls you hear are all very aggressive sounding noises.
Male vs. female
As far as the difference between male and female sounds, the female is higher pitched than the male and she does most of the talking. If a male is paired up with a female you won’t hear much out of him. She’ll do enough talking for the both of them. Usually only when a male is by himself will he do much talking, and you’ll know it by the long heavy sounds of his barks and howls.
The male is the more aggressive of the two as far as coming to a coyote call, and he would much rather come in and get the rabbit or pick a fight than stand out there and talk about it.
By putting some friendly barks and howls together, we can make one of the most useful sounds to the predator caller, the integration call. This predator call is used to get a coyote or a group of coyotes to respond to you, or they may just come slipping in to see who is making those sounds. The latter usually only happens when the Integration Call is combined with a few prey-in-distress calls.
The integration call goes like this: two long friendly howls a friendly bark, a short pause then a short friendly howl and last a long friendly howl. You can put two of these sequences together but usually no more than that. There is nothing wrong with changing the position of the barks and howls to get a coyote sound you are more comfortable with. Wait five minutes and repeat.
If still no answer, you may try to salvage the stand by throwing out a few prey sounds and wait five minutes to see if a dawg shows up. If not, it’s time to leave onto another bunch of coyotes.
