yes you guessed it he came back tonight but he was in my front garden somewhere he has not visited for a while.i have a berberis shrub and the sparrows hide in this thorny bush but to night when i heard the sparrows and went out he was actually in the bush hunting.think he maybe feeding a female as i have never seen him go into this bush before.anyway he flew out on seeing me and flew in the other direction only to fly back and perch on my fence looked at me then the remaining sparrows who had not fled to another safety zone and he went into hunt mode again not bothering with me until a neighbour appeared about 40 feet probably more away and he flew off.this behaviour had me thinking does he recognise me or is it just my garden he sees as holding no threats and if so why would he fly off when the person was not near the garden and i was less than 12 feet from him.
