Marie Winn had wondered on her site if the four owls we had been seeing were actually just three. (Update: On of Marie’s reader’s wrote in to report having seen all four in the same day. I think we all ended up agreeing that there were four owl.)
So, I dug up some old photos from the Riviera and the West Drive cavities. The first two owls are from the East Side and the second two owls are from the West Side I’d say we have (had?) four owls, but you could argue three.
