and it was a gray fox. At first I thought it was someone's small dog but it was walking away really fast and trotted right past a rabbit that was frozen in place so I assume it had it's breakfast in its mouth and was heading home. So I then did a search on gray foxes and found out they can walk right up a tree trunk!!!! So that was a scary thing to know. Anyway, all this time I've been looking for a red fox not a gray one. So birds that roost in trees would be in danger from foxes...I had no idea. It also said gray foxes are smaller than red foxes so they can get through smaller holes.
