Opting for the less subtle technique of sitting on the feeders, hoping nobody notices. To cut a long story short, it didn’t work. He sat there for ten minutes, then left when someone walked past the hedge.
Most likely he had a go at something on the feeders, missed, so stopped to recalibrate.
On the upside he did sit there for quite some time, which was a treat. Although he wouldn’t turn round to show the full glory of his plumage.
About the best view was the one I got when I first spotted him, but I hadn’t set up to take a picture then so it’s not the greatest quality.
It was a lovely bonus nonetheless as the Sparrowhawks rarely sit still like this, and he was clearly in glorious condition.
