Will do. I would have to record all day to catch it, and my cameras don't have that kind of stamina. I'll have to get lucky, have him be more predictable, or figure something out. I could certainly record audio for long periods: my Zoom H4N has a "Stamina" mode to help batteries last all day.
Ah, I can remotely start video recording when I hear him do something interesting, without disturbing him. Anyway, covert bird watching is another topic of discussion entirely!
