Some excellent images on your Flickr Photostream, including the Kestrel with the dragonfly, other wildlife and a whole album of aircraft images. Great work!
I've seen Common Kestrel 'trying their talons' at insecting on many occasions, including at Shapwick Heath in previously years alongside the Hobbies in early May. Another memorable observation was one behaving in this way with a flock of 50+ Red-footed Falcons in northern Tunisia in Spring a few years ago.
