Orange stain signs, associated with probable rabbit tracks in snow.
No interactions present.
It is rabbit urine, I think.
Doe rabbits are in season already,so blood in urine.
Watched some last night courting/chasing in the snow.
The exact same blood marks on snow this morning
Thanks - makes sense!
Hmm. See http://www.greendale.co.uk/rabbit_urinalysis.html.
