What time doe's this pub open?

I had tried to catch this Robin several times as it flitted about my garden but without success then one day whilst checking the resolution at various apertures at 200mm of my Pentax 50-200 zoom using the bird feeder as a target the Robin paid a visit without me seeing it It must have appeared and disappeared very quickly luckily it was caught in a shot with the aperture set to F 6.3.
Best viewed enlarged to see the detail in the Robin. I think the lens done a good job
