I really like crows. Some days ago in El Cuera mountain range, Nortern Spain, one of them put to flight a Golden Eagle just when he was trying to catch a lamb.

This scene is very similar to other, just in the same place two years ago, when a Crow put in flight a Golden Eagle when it was attacking a Bearded Vulture
