After wandering around the garden for an hour, with little hope of finding the bird due to high winds, I spotted him on the ground feeding (with a cigarette perfectly placed for scale).
Apparently these birds do a lot tail flicking and fanning as they feed.
And as a result you get great views of the white in their tail.
A pause for breath.
It spent most of its time close to a small maintenance building, flycatching from perches, or feeding in a bush, staying clear of the wind.
