For how long does DC do that swooping? I know he's been at it throughout the day, but does each period of swooping last just a few minutes like the video, or for longer periods of time?
Looks like an intimidation factor.
Has anyone seen this behavior at other nest box sites?
Margaret, this is the longest session I've witnessed yet. The video doesn't show all of it-I think there were upwards of 20 swoops altogether. I also saw a session where he swooped on her only twice this morning.
