I came across this bird hopping around the rocks by the shoreline. It was behaving a bit like the local Stonechats, taking off vertically, flying a tight circuit and then landing on a nearby rock.
Unsurprisingly, it was somewhat more timid than the Stonechats and at one point seemed to be chased away by a territorial Robin.
The rather blurred picture below illustrates the extent of the coloured rump and tail which flashes flame orange when the bird takes to the air. The main picture will enlarge.
