A friend found a barred owl (Strix varia), dead, in the woods. After a few months in contact with the busy soil critters, the bones were clean. I am fascinated by the double-domed shape of the cranium.
It's interesting to compare it to the skull in the owl sketch page I posted on my "classes" page. I think that one's a great horned owl. This one is smaller, a bit more delicate, with a shorter bill. Also, the frontal bone (just above the beak) of the barred owl is much less swollen-looking than that of the great horned/great gray owl.
