This sighting was actually made by Frank Chappell. He observed the bird at one of viewing locations used during an event for the "Wings Over the Rockies" birding/nature festival. It's held annually in the Invermere/East Kootenay area during the first full week of May (19th year in 215). I was the tour leader for the event and Frank was a participant. He contacted me with the observation as an FYI. Brian Wesley.
