This year's Barred Owl nest‏ Joe Meche 7/24/13

It's common knowledge that the BADO's of the previous two years abandoned the well known nesting tree in Whatcom Falls Park and set up in a new site. I think I found the new nesting hole this morning and, given the proximity to the area of frequent sightings this summer, this might be the tree.
Tough to tell in the photo, but it meets all the necessary criteria and you can see old nesting material falling out of the entry hole.
