Thank you both for the recommendation. I just had my wife order a copy for me.

Jaguars are larger than mountain lions. The specimens that show up in the Sky Islands of SE Arizona are a little lighter than the big boys of South America. I visited with some Coues deer hunters that have been hunting the exact same area in SE Arizona for 30 years, in early 2025, they told me that they had seen one jaguar track in those 30 years. Told me that track was much larger than any mountain lion track they had ever seen. I was trapping that area and just knowing that it was possible to have black bears, mountain lions and jaguars in that vicinity was a super cool experience. There's only been five or six of the big cats actually documented in Arizona in recent memory. All males with their pictures taken by trail cameras or bayed by a lion hunter's dogs. No breeding population is known to be in the United States. Each animal has a specific color pattern that ID's them just like our fingerprints do.
I had some other deer hunters that leased a ranch in the Sonora area of Mexico send me a picture of a jaguar at a water tank on their lease. There is a jaguar reserve in Sonora, Mexico that does have a breeding population. That's where biologists think our transient jaguars travel from.
I'm a retired Game Warden that should have been a furbearer biologist.

My family used to hunt them in Louisiana during the mid to late 1800's. My great grandfather who was a trapper and logger said that when they were logging Lake Maurepas and the surrounding basins they still had a few jaguars left as late as theearly early 1900's. The last one reported in a news paper was 1886 around Donaldsonville. But remember back then they didn't have the internet to blast what they were finding. There was Florida panthers all over at that time, but he talked about big spotted "tigre", which was the common name for them down here. Florida panthers were called "panther" or "panthère". I also believe that there was a smaller version of the jaguar or a unique strain of Florida panther as all the old timers used to talk about "black panthers" who would attack livestock.

There has been talk of reintroducing the jaguar to Louisiana, bad idea.

Showed up today. I'm looking forward to reading it.

I'll third "Tigrero"

Warner Glenn actually caught two jaguars over the years. He is right down on the Mexico border and they were transients. Personally while I found the book cool, I wish he would have kept his mouth shut. The antis use any reports of unusual/rare critters they can to try and shut down trapping and hunting.

I believe all the Dale Lee tapes are on the Born 100 Years Too Late youtube channel, or published by the same guy (Brett Vaughn) as podcasts. Very good listens. Life of the Greatest Guide is a book by Dale Lee (actually written by someone else, but written first person from Dale's perspective, by a guy who interviewed him and recorded the interviews) that is very good, but be aware that the book and the tapes are pretty much the same material.

When I ran hounds I read a bunch on them, that was a long time ago, always heard they don’t really tree like a cougar, just bay them up and loose dogs to them. Most cougars tree fast, a lot are right next to a tree well. That’s where a big Douglas fir or white fir tips over and the root wad tips up. Big cats like to nap in those areas. I’m sure bobcats do too. I couldn’t count how many cats I’ve seen treed next to those root wads.
