That's not a loose theory at all. I've proven that to be true time and time again under cameras. I repeatedly tested 10 gland lures from 8 lure manufacturers and found 4 lures that I would use with confidence and one of those 4 lures that proved to be "the best of the best", the business has been sold and I don't think the new owner is making/selling gland lures anymore.

^^^^^quote of the day 4 sure^^^^^

Spot on.

I agree as well and that was also a known factor during all of my testing the last 3 years. It was very opportunistic to have done the gland lure testing the year I did because the coyote populations for 2 years prior had been in a downward trend. The spring of 2021 the population was so low I had difficulty finding coyotes to test let alone trap during the 2020 season!

Seldom,
What caused the downward coyote population turn....mange? parvo?

Mange played a role because I all of a sudden was catching coyotes that appeared to be recovering from it. I really believe the big deal is the sharp upturn in night-hunting here. Everybody and their brother are seemingly into it. Silencers, thermal vision year round and especially in the spring during denning has crashed the coyote population. Several of my large farms I've trapped before , this year the owners had to ask the night-hunters if I could trap and you can guess the answer to that.LOL I had properties that I'd trapped 3-10 coyotes a year on that I never set because of no sign but turned around and found out after the fact there had been night-hunters there for 2 years that I wasn't aware of.

I personally stop using urine all together years ago because deer would not leave sets alone. Then I noticed my catch went up two reasons I would suspect deer leaving sets alone so more sets working and I personally thing the bigger reason is no urine at set has really helped me

I catch dozens of coyotes on just urine alone. There’s definitely a difference in good, real urine and other stuff.

I have run into the same situation locally over the years with night hunting. Places I could count on for fox and coyote no longer produced as they had in years past. The canines just eventually avoided these areas due to nighttime harassment and other spot lighting human activity.

Folks got these side by sides and want to roam around after dark, prime game movement time, to see what they can see. 2-4 folks carrying on during this time frame will spook the locals and eventually cause them to change behavior and move to other less active areas. It may take some time for them to return to their normal activity if they ever do.

Once game cams became available, I put some out in my once productive areas to see what may be happening. Over time it all made sense as to the poor to no catch situation. Then the locals talk to give you more information.

The greed factor and territorial response goes way up. I've seen both, it makes a huge difference in how coyotes react.
I also agree the thermal folks are the biggest reason we have less coyotes and I've found numerous deer with little bullet holes with their racks missing. I've had coyotes shot in my traps too. The DNR opened pandoras box when they allowed thermal and no season. But we can buy 10 doe tags, ya can't make this stuff up... A lot of the thermal callers kill so they feel like big men and toss them in the ditch, the DNR does nothing. If I did that to a deer, they'd go ballistic. Sorry for the rant

I've started saving yellow snow for late season coyotes, The urine I purchased from Keg Creek opened my eyes to the difference quality makes.

Who remembers when they used to 'make' fox urine with food coloring, ammonia, water and one other ingredient ?

Ain't it the truth !

Does anyone else notice a difference in deer issues when using fox urine vs coyote or bobcat urine? I don’t use fox urine anymore just for that reason.

I sure remember the synthetic "grocery store goods" made urine some years back. In fact, I know a fella that did it and told me about it. Why he did that I don't know, sure makes you lose faith in someone who you thought was a straight shooter.

COON CREEK TRAPPERS supply in Frills Corners, PA has fresh fox urine from penned animals. Try them if you're close

I have not noticed any difference with urine but I made a salted bait once from an old recipe and every trap around it was snapped by the deer, lol. Not my brightest moment. I will look more closely for deer issues with fox vs coyote or bobcat in the future though.

Looking forward to your tests. It's kind of funny I was in the lure room tonight (before I seen your video), I was going to pour off some of the unfrozen urine on some of the coyote urine I collected this year. Anyway while out there I noticed some bobcat pee from a reputable (or at leasted I assumed they were) dealer that claims to collect it himself and claims it 100% pure pee that was as liquid as it can be at 10 degrees. Again no mention of antifreeze in description. Setting beside it was bobcat bladder urine I collected frozen as solid as can be. I'm going to put some I collected in front of a couple of cameras Saturday

Very interesting Yes Sir! I’m wondering if the concentration of urea is higher in bobcat urine from being froze-down??? Lots of questions but the cameras will help point us in a direction for understanding more than we know now! I’m really looking forward to start testing urine in maybe a few weeks.

Bringing up an older thread. So, who is willing to say who they trust when it comes to good urine?
Back in the 70's and early 80's there was a guy in Bradford, PA named Harry Judkins who kept a dozen or more red fox. I used to bring him over deer scraps, road kill, wood chucks I shot, etc. and he would give me urine. The only time I have ever smelled urine as good as that was when I sniffed a spot in the snow where a red fox had squirted. I could smell that from 10 feet away on a calm 10 below zero morning. I will say the urine I got from Bob Jamison is pretty darn close. If you ever see me in January out in the snow covered fields with a spoon and a jar, you'll know what I'm doing.

I remember visiting with Harry many years ago when I traveled to many of the conventions. I was a very young man back then probably in my early 30's. He knew who I was even though I had only been in the business for a few years back them.

He was up in years then as I recall in his 70's I would guess. He shared with me that he liked to make many of his fox sets down inside low hollow stumps as he had much success with that set up. I would assume he trapped in many large hardwood areas.

I trapped some years ago for short periods of time not far from Bradford as my then father in law lived in Mt. Jewett. It is a well forested area where I trapped and not much farm ground. Power lines, woods roads and some grassy right of ways is about most of the area I briefly trapped.

On that last visit with Harry was in the early 1980's, I never saw him again. I still remember our visit and he gave me a couple bottles of lure I still have sitting on one of our shelves in the shop. I think of him on occasion when I see one of his bottles in my shop and remember our last conversation.

He had good urine as I recall since I make it a practice to smell things as you can imagine. Funny how things tend to stay with you in your memory.

He was salt of the earth, a very kind man. Did you know Ned Stark the fur buyer from Eldred, Pa? What a wonderful character he was. Always gave fair prices and paid more than he should for what some kids brought in. Bought all my furs and ginseng for many years.
