sparrow hawk

We have a sparrow hawk regularly passing through the garden, (I assume it is the same one). Twice in the last 3 days he has panicked male chaffinches, which crashed into the window about 2 feet from where I was sitting. They then hit the ground stunned or struggling & he can calmly pick them up. Yesterday he sat on his prize for more than a minute, so a superb view.
It certainly brightened up a miserable day!
