The garden is full of activity at the moment and this is one of a pair of robins who I think are going to rear their young on top of the blue tit box in the ivy. They did this last year and I posted a pic of baby George who I named as it was St George;s Day 23 April when I first saw him on the path. Here is the link to his pic https://365project.org/rosiekind/365/2016-04-23
