Pair Bonding

I know this is not clear and has been heavily cropped and sharpened but I wanted to record a phenomenon I have never witnessed until today, that of Mr Robin pair-bonding with Mrs Robin by feeding her treats, popping it into her beak. In fact, I saw this towards the end of the garden first, they then moved closer - all seen through four layers of glass and on full zoom.

To clarify, the extra shows them again,  Mr cock robin has moved to the right, Mrs hen remaining in her original position.

Thanks to Sallymair and Pleach for the ID of my tree yesterday I have edited the text.
