So I set out some weasel boxes and caught my 1st and 2nd last night. One was all white and the other looked like it was still changing color. Is it normal for them to not be all the way white this time of year in semi northern MN?

I guess it varies a bit.
Most all are white here now,but I picked up a greyback the other day.

Ermine are awesome! Congrats!

I hope ours are not all white yet. I want to get one brown, one white, and 9ne in between to tan for wall hanging. Been trying for three years and finally found some. Caught my brown one already and will be back to set again Friday. Hope I can still get a mixed color one and not wait another year. Lol. First weasel I even even seen.

Do there coats change from brown to white in winter?

In the northern part of their range, yes. Places with a more moderate climate, their winter pelage is often brown, like summer.

They definitely change color here....

Ok I figured they would be mostly white by now. Kind of like the look of the in between.

The brown weasel in Shanemoss's photo may be a least. Some more photos and a length measurement might help ID.

Top one all white-caught 5th of nov
Second one a greyback caught 22 of nov same area.

Good Job

using the chain as size reference ,I don't think it is a least, they are usually the thickness of your fingers

A few never do change all the way, and I have seen a few over the years that change little or not at all, the taxi man I sell mine to prefers and pays more for the pinto ones

I only have a sample size of three but all were white here by 11/20

Guess it'll be another year to round out my trifecta then.

Short-tailed weasels (ermine) and Long-tailed weasels turn white... does the Least Weasel - keep its color like a mink?

Just like the other two North American species, the least weasel does indeed turn white in winter in the northern part of it's range.

Weasel are such cool animals. I liked trapping them more than anything else since I was a little kid.

Although I have never caught a least weasel-they are supposed to be easy to identify,not only from overall small size but apparently they also dont have a black tail tip.

I have never caught a least weasel either. But, I was told the same thing by Skulls Unlimited, a least weasel doesn't have a black tip on it's tail. That's how you can tell them from a short tail.
