Pathfinding

One of my new surveys involves following a route laid out already by someone else so I took some time to follow it today. It was mostly successful. There was one part that I will have to revisit as I couldn't quite figure it out.
There are up to 3 robins vying for top spot in the garden at the moment, and a blackbird is busy collecting nest material. We also had a flying visit from a Long-tailed Tit.
