No interactions present.
I was a bit cautious, at first. But, with Ardea's agreement, and looking again at the grey neck side, I think this is a correct ID.
Interesting that the bird is ringed. I had a Garden Warbler, which I ringed locally to me in 2009, killed by a local boy, with a catapult, in Ghana, over this winter. Several ringed Garden Warblers have been found in Ghana, telling us that it is a major wintering area for the species.
