There have been kestrels living on Union Mill, visible from the platforms of the railway station for a long time. But it seemed that whenever I took my camera to try to get a picture, they decided to spend the day somewhere else.
Finally I saw one when I did have a camera. It did eventually move into a position where it was showing itself just before my train was due to go. This was after it had spend some time with its back directly pointing at the station (final picture).
