Blue Deer Urine?

Default Blue Deer Urine?

Well, I searched and found nothing, so here's my question? What in the **** causes a deer to urinate blue?

If you guys want pictures I could probably snap some tomorrow but we own a small food plot that is quite popular with the deer. Now when I walk through the woods/ravines I find many spots where their urine is blue, literally blue. It's kind of half and half with the brown urine as well.

I don't know, maybe it's not an odd thing but it's the first year I've ever noticed it. Dad told me about it first and I thought he was kidding, nope, I found at least a dozen spots out there.

I remember it being a dietary thing. There is a plant that when the deer eat it it turns their urine blue. It is not a preferred browse and they tend to eat it later in the winter as other food sources are expended. Blackthorne or Dogwood comes to mind but I am not sure.

I poised this question about a year ago and the answers were all over the board...
If my memory serves me correctly it was some type of berry bush that caused this.
Hopefully someone can come to the rescue?

I like to think there are real life Smurf's, kind of like a Sasquatch!

I have seen this but obviously only in the snow. The area was where deer were feeding heavily on corn and acorns. There is a plant that has a leaf that stays purple all winter here in Ontario and it usually grows in low lying areas. It also has a red berry at times. I'm not sure if the deer are eating it but they have been known to a lot of different things including poison ivy. In winter, I notice they will dig through the snow to find the ferns that are still green and I notice some other plants that stay green all winter that the deer will flock to. The only thing I can think of is if the deer are feeding on something that is extremely high in vitamin E which is a naturalanti-inflamatory and in high doses will cause one to pee blue.

I'VE seen it in Central NY too - Often times - I assumed it was rabbits though - not deer - but - it could be.
I've wondered in the past but not spent much time figuring it out.
