I have not seen the E.L.K. vid yet. Might have to pick one up.
I have to agree with Jerry though. I haven't seen a vid that I felt could take a novice and give him the tools he needs. It is just not something you can watch and go out and do. You have to put some time in annoying the wife, kids, dogs, cat's, and neighbors with your dedicated practice. LOL
Both of Randy Andersons vids were very strong in the howling dept. I recommend them highly.
Sceerys vid could help identify the different sounds that coyotes make, if you stay awake. LOL. Learning the difference between a warning bark and hunting bark is certainly a plus. heh heh
The two best things I did to help my howling was:
#1 If you don't own a couple recordings of coyote vocalizations, get a couple. Then grab your open reed and try to imitate it. It won't be perfect but you will be surprised how close you can come. A couple Johnny Stewart tapes can help a lot. Lone howl, challenge, pup distress would be a great start. You could buy all three for under $30 and listen till your hearts content.
#2 My favorite is simply going out night calling. The coyotes are much more talkative at night. I just start off with some friendly lone howls and try and imitate the responses.
Nothing is as valuable as getting in the field and experimenting. You will quickly find out what does and does not work.
Good luck
