My guess is bull moose rubbing the Velvet off of his antlers.

My guess is...a moose ate the bark.

Well there wasn't any moose tracks around and there was a pile of bear scat right next to the bigger tree. But maybe.
Let me rephrase that...I know for a fact that a moose ate the bark off those trees during the winter months. If it was a bear clawing the tree, it would have a more shredded and gouged look, not the peeled look in the pics you've posted.
"Grin and Bear It"
There no way of telling for sure what made the marks with out knowing more information. Such as how long ago was it made, was it there last week? Do you have a picture of the scat? Are there any tracks? From the picture it looked like it was made by teeth, do you have a close up so we can tell how big the teeth are? If it was made by a bear are there claw marks? If a bear used his teeth it would rip off the bark not eaten it.
Tearbear is right, definitely moose chewing the bark in the wintertime.
Well, I hope its a blacky. Would sure be better luck than I have been getting.
What does the scat look like? Consider using a game cam at the bait station.
Moose. I watched one eat the bark off a tree in my yard this past winter and that's exactly what it looks like now.
Well good, makes me feel better its moose instead of a bear that close to my bait and not hitting it. The only luck I have had the last three years on anything bigger than grouse has been bad luck.
100% sure that is where a moose chewed the bark off most likely a willow tree. Although I have seen them do the same to aspen and poplars. Little bit of tasty chlorophyll in the bark is a delicacy to a moose during the lean winter months.
Most of the trees I have seen clawed up from bears are in spruce trees. And you can almost always find hairs in the scratch marks that can identify the bear as either a black or a brown.
