Mike, they are thrilling to hear and see. We live above Thornton Creek, where there is a nesting pair, and we hear them from time to time and have seen them in our yard a few times. They seem to be the only owl species in the neighborhood.
But I wanted to note that they are not an invasive species. An invasive species is one that humans have transported out of its normal range and, often unfortunately, does very well in its new location at the expense of other species.
Barred Owls, on the other hand, expanded their range naturally across the Rockies and then down the Pacific states. The only thing we had to do with that probably involves the habitat changes that we have made over time that facilitated the owl’s expansion.
Yes, they are threatening the existence of endangered Spotted Owls, and they may be involved in the disappearance of screech-owls from some urban areas, but they are a natural phenomenon, much like the variety of bird species that have expanded their ranges north from California into Washington without such apparent consequences.

Eventually we were able to see one of them in a tree near the trail, but it was amazing how hard the bird was to spot when it was only maybe 30 feet away. It was near the point marked 17 in the map here: https: //www.fodp.org/maps/ <http://www.fodp.org/maps/> (remove the space to open link)
