This observation is as much to do with the location than the robin. See notes below.
No interactions present.
I discovered this lovely resource in the heart or London the other day. www.nhm.ac.uk/visit-us/galleries/orange-zone/wildlife-garden/index.html
The Natural History Museum’s Wildlife Garden is not large but they pack a lot in. Ponds and a reedbed are surrounded by hedgerows towered over by London Planes. These are brimming with bird and bat boxes. There is even a meadow with sheep! (On loan from that other fine place London Wetland Centre.)
I recommend a lunchtime visit if you are in the area, unfortunately they shut it to the public over winter (boo hisss) so best hurry.
I agree, it's an oasis in the heart of the city!
