It is humbling.
I had to quit watching DVDs taken in warmer climates and conditions because it wasnt realistic for our typical december prime coyote taking here. I liked some you tube vids I saw of local guys. Papio creek is just to north of me and his late season techniques and terrain is spot on to where I trap. But I've also just put in the time and learned what works for me too.
Some days I stare at empty sets and wonder if I was way off on location, then couple empty checks later and I have a double.
Got one farm that produced 3 in first week last year. This year exact same locations setting on sign and haven't picked up any there. Not even a fired trap or print in a dirt pattern. It's a cool location too, maowed hay field right next to a very wooly overgrown cedar thicket in middle of section you can only walk into it. Nothing and I have 5 sets spread out back there. But on very Next farm over, I got three this year and last year it was all blanks for a whole month of checks. Last year I threw 8 out of first 10 away due to mange. This year knock on wood have no mange showing up yet.
also had a couple coyotes shot and stolen from sets last week. Way back in middle of section, i set back in there on purpose to avoid the idiots but this year they drove up a steep ditch to get in and it was truck tracks around all the draws and edges, and of course right up to each set and didnt even try to hide the crime scenes. At least they left the traps this time. But with higher coyote prices the loss hurt.
When prices are up on coyotes it's a tough game around here. Everyone and their best friends are out driving and hunting them. Numbers go down fast and the whole world becomes these guys playground whether they have permission or not.
Last year all of december was basically mud here. Rained a ton early in month then freeze thaw every day and tough dirt trapping conditions. The yocals couldn't drive everywhere and I hauled a lot of waxed dirt into sections but had one of my best coyote years ever. This year mild temps, dry conditions, folks driving everywhere and issues with theft, and catch rate is way down. Some years they plant corn some years its beans. Every year is different.
Roll with it. Every year is different with new challenges. I digest all of the pro tips I can get my hands on, but I also realize I'm fighting weather and a lot of other influences around here than just my own abilities and techniques. Keep a positive attitude, keep learning, and it's ok to be humbled especially with coyotes.
