Keeping an eye on things

I have seen this young kestrel swoop past the feeders in the garden several times in the past couple of weeks, presumably in the hope of catching a small bird unawares.  It then flies up into a 30m tree in my neighbour's garden, from where it can see over several gardens.  The photos were taken with the camera balanced on the roof of the car outside the front door.  The distance is about 60m (200ft) with a 600mm lens working at an effective 960mm and heavily cropped, so the photos are not too bad considering.  The kestrel's eyesight is so good it probably has a much clearer view of me.
