Hi David, Thanks for your kind reply. I would have loved to have seen your Great Horned Owls last year. Before I made the post I thought about whether I should or not and I decided that Great Horned Owls are hardy guys and wouldn't be bothered by people looking at them from the parking lot. The only way I figured someone would harm them was by climbing the tree and that seemed a bit far fetched. But as I said, I didn't realize that going around to the back of the tree would spook the owl. At any rate, I hope they make it through the nesting season. I am pretty fascinated by owls. If you have reliable sites for any, I would be most appreciative if you'd share them with me privately. I won't post them, I promise! I live in Centreville am out in Loudoun Country a lot but I have only seen a Barred Owl and a Northern Saw-whet. Heard Great Horned but not seen out there.
