If I understand what is happening here, the Robin sees his reflection in the window, and the combination of their general territoriality, and that it's more or less mating season (when this is likely important) he is trying to chase off the rival robin he sees.

This is a single time, of him doing this, for 15 minutes.

I have been trying to chase him away, and it seems like it is somewhat effective, though I'm not sure he's not merely being displaced.

I'm likely to post new stuff here, because even though YouTube is "better for views" I didn't find that in the past, so I think there's not much reason to not use PeerTube.

Also, it probably would be good to look at handling imports from other services.
