The WT sparrow(s) that I had in the backyard for quite some time have been a no show for the past couple of weeks. Yet they are still relatively abundant in city parks. I haven't seen the Song sparrow in the yard either, which surprises me because it was acting like it owned the place, so I reckoned on an extended stay. I should stop making assumptions. Juncos are still here though, every day, all day. Grackles and RWBB have all but disappeared. Every time they showed up I could see them, or hear them and so I slid open the door and off they went. Eventually they didn't even bother to return. So, what you really have there is a Grackle CAM.
