Differant mule deer

Growing up in the far western counties in Montana, I was quite surprised when I saw my first eastern Mt deer. The western mulies don't have high rear points and somewhat resemble whitetail. They have overlapping ranges and often you would see a whitetail on one ridge and mulies on the next.

My question is has anyone seen or heard of any genetic studies that would indicate the interbreeding of these species? Just curious.

No. The western bucks have little length difference between the first branch and the second. Eastern Mt bucks have twice the length on the first branch than the second. A more classic muley.

I read an article in one of the outdoor magazines years ago that discussed this. I don't think there was any science, just observations similar to what you are describing. I would think that there would be other physical characteristics in addition to just horn configuration. Interesting discussion though. I have seen similar bucks down in Eastern New Mexico.

I shot this muley in So AZ. It clearly has White tail genes. I researched and discovered the Sonoran White tails from Mexico would breed with the muleys and create these types of bucks. The year I got this guy, there were typical "tall" antlered mule deer all around and none like him. I mounted him as he was unusual. Sadly he was at that 7 year range and regressing size wise already from the previous year.

Sadly? Man killing a 7yr old deer is something probably 95% of hunters will never do. Who cares about him regressing a little. Hell he could be a forky and he would still be a trophy in my eyes. Outsmarting a 7yr old with a bow is an accomplishment in and of itself.

Duwane Adams killed a whitetail/mule deer hybrid in southern AZ a couple years ago. For a while, everyone speculated that it'd be a new world record under the Coues deer catagory, until genetic testing was done. There's been several of those hybrids killed in AZ over the past few decades. Pretty interesting twist of nature .....

A lot of that country along the western Montana border have muleys really high and whitetails in the bottom and both inbetween.

Thanks for the research. Even the high muleys don't have racks similar to eastern Montana muleys. They are all very similar to whitetails.Many have multiple points off the main beams. I have killed a couple in the 9x11 range.

Normally yes, I was fortunate, the rut was on and he had hot does every where and lost all sense of wanting to live, as he was wanting to breed more. Right time right place for me, not so much him.
I knew nothing of this deer until 4 days into my hunt, when I spotted him with a limping buck and a dozen does. Next day I spot the limping buck and drop in from my vantage point gambling the big buck was there some where. In the desert it's so open you have short windows of opportunities and playing it safe is usually not one of them.
Once word got out he was dead, emails and texts flooded in on the stories of this guy. He was watched one year mauling a non responsive doe unwilling to breed. He killed her. Likely the limping buck lived close by, only because he was limping and limping badly, he was no threat. The stories are endless with this buck. They called "chocolate" and others called him OJ, all because his dark colored horns. I called him yummy. Old desert bucks do taste yummy.

Not "genetic studies", but yes, more than a few articles out there. If memory is right, Whitetail bucks more successful at breeding Mule Deer Does, but Mule Deer bucks not so successful breeding Whitetail Does, so even though offspring are sterile hybrids, the Whitetail does tend to produce a whitetail fawn while the mule deer does produce a sterile hybrid. so where they overlap, the Whitetail tend to outcompete the mule deer.

Totally from memory, don't ask me to prove.

Guided a hunter in mule deer country but he killed this Hyrbrid there. We've seen a few whitetails in the creek bottoms so there is opportunity for overlap in breeding. If this truly is a hybrid, according to what I wrote above, odds are it came from a mule deer doe, essentially eliminating her from the breeding population for that year.

He was a big bodied buck. 232 lbs. hog dressed; I wished I would have lab aged him

Wow. We have been looking mostly at horns but the buck that Robby has shown really physically looks like a mule deer AND a whitetail got smooshed together. Huntngolf's buck has a very unique set of antlers. Very intriguing.

that deer is not a muley hybrid. I have one in my house also like that and its 100% whitetail
Oh I know its a whitetail. Should have worded my initial statement differently. Just interesting that its antlers have some characteristics typical of mule deer and there are mule deer in the area
