Went for a walk a few days ago. While talking and singing and making noise my nephew and I scared off 4 coyotes as we unknowingly approached their den. We watched them run away and then inspected their home. I was surprised to find it so close to our house. The peak of the rock where you see the dark hole is the entry (about 3 ft high) and there's about 10 sq ft inside. Plenty of room for some pups. I suppose the coyotes have to live somewhere and this looks like as fine a den as any.
