You can take what Bob Mc said to the bank. Also, you will have to spend more time scouting your calling areas, and most importantly, learn the habits and idiocincrouscies(sp) of your quarry. He is NOT a coyote, and can not be called like one. This is the biggest mistake most would-be lion callers make. They dont know what makes a lion tick, and, they dont walk enough, and, they have little idea of how to call one. Sure, some guys can call one in 3 or 4 times in a lifetime while trying to call coyotes or fox or bobcat. But to call 10 to 25 a year, you must KNOW what,when,where,why, and how to do it. Most men just dont have the inner fortitude to push themselves to the limit or to spend the time it takes to learn how do these numbers. The 17 lions I called in for clients last year was the hardest work I have ever done in my entire life. The 25 I called in the year before were much easier to do as the weather was much more favorable. Last year the weather was horrible for calling lions consistantly. Few know how weather can affect your calling success on the big cats. Your home state of NM has a tremendous lion population, and some areas are overrun with way too many cats. Calf. and AZ also have too many lions. My advice, use more lion vocalizations than prey calls and your success rate will skyrocket.
For what it's worth,
