I can see why this is one of your favorites. The colors and reflections and shadows give it a sense of abstraction, which takes the image far beyond a subject of two birds. Also, the image portrays something that's universal, whether it's Poland, London, New York, or Tokyo, urban birds' appreciation of a puddle of water. (They also appreciate outdoor restaurants, hoping for free food, and I've wanted to start a portfolio of them :-).
