On this subject I typed alot and when I pushed OK it froze and never made it, so if it happens again I will be pissed.

I brought this topic up about 4 years ago. It was legit in that I heard a seminar was going to cover the topic of blue urine coming from deer. I bring this up because I came across another spot on the snow that was blue unlike the many spots I noticed 4 years ago.

Has anyone seen research on this topic? I am assuming it has to do with nutrition........

That is the first I've heard of this. What shade of blue is it? Is the color almost a shade of blue like Windex?

It is really noticeable and yes it does look like Windex. What I saw in the past was noticeable being it was beloow freezing. The most recent that I had seen was not that visible due to the melting snow. The last 3 years I had not seen any.

Wonder if it could be caused by the deer eating certain wild berries?

Not to many berries in MN this time of year......

I've never heard of blue deer urine before. I really don't have any idea what would cause that, but I'd guess minerals are to blame.

No arguing that. Very odd...

ask the dnr thats what their are their for, let us know, i think all of the points over top of me are good ones

When I was a kid, the folks would put Potasium Permangamate in the chicken's drinking water to prevent some kind of disease (it turned the water a deep purple). Then when I was in the Navy, some guys slipped a little of it in the big coffee pot! When the guys went to the bathroom, it was PURPLE! Scared them half to death!!!

That was funny oldguy.

If it was do to the drinking water you would think it would be present everytime.
