Best Photo of kingfisher I have got so far

Found this little fellow today. It is a really bird of unimaginable beauty. It can hover on one place. It can dive into water in a blink of an eye. I'm now obsessed with another creature to capture closer then this.
Current photo was taken from the shore of a lake. Actual bird is about 100-150 meters away.
