I came across this story written in the snow yesterday as I was snowshoeing with my dogs. I don't know what left the tracks in the snow, but I have a pretty good idea of what ended them. A small rodent of some kind was surprised mid stroll by a raptor. Either a hawk or an owl judging by the size of the wing marks left in the snow.
I have seen a hawk in this area but haven't gotten a good look to verify exactly what it is. My guess is a red-tail. I have heard reports of a snowy owl in this area as well, but have yet to actually see it.
These types of stories are written, by wildlife, across the landscape all the time. Taking the time to find and interpret them makes our outdoor adventures more enjoyable. Being able to share them with others makes our adventures even more rewarding.
