In reply to Michael Hood:
I regularly have sparrow hawks through my garden. They are so quick, agile and quiet. More noticeable to see one if it decides to stop for a look around or if it catches something. At least three catches of small birds this year I’ve seen, about 5 fly straight through, and had 1 stop and look around!
There is a regular line they take through my garden and last year one actually flew within 3 feet of me sitting. Not bothered by me at all as it even stopped momentarily on the fence and had a look around.
Recently this year, I was siting in the garden with two friends chatting and the first I knew that a sparrow hawk had taken a house sparrow was when it was taking off with it from behind plants at the foot of a wooden fence. Never heard or saw it catch and land with it, but it struggle to liftoff with being next to the fence and the plant foliage.
