One of the aspects that most fascinates me in Nature photography is trying to capture the essence of a certain subject. The Common Raven is a particularly clever and wary bird. In the territory of predators that would consider him an adequate meal he scrutinizes its environments carefully, looking for the approach of an eagle.
