I'm aware that Robins can be somewhat agressing but most people talk about inter-species agression rather than with other species.
Recorded this yesterday where Robin seems to "go for" a Dunnock". They have their squabble outside the focus of the traicam but not so blurred you can see what is going on. It's only the 1st 5 seconds that show anything (after than it's just the trailcam timing out its recording).
Do robins do this a lot and/or under what circumstances?
