Yup, Corvus corax, the largest perching bird in the world. It is a very common bird in my area, to the point of being almost invisible. They are considered a nuisance because they forage through garbage, tearing apart bags and spreading contents everywhere. They are the original dumpster divers. The other morning I saw 150+ hovering at our local dump, like a great black wing, smooth as silk, gleaming in the sunlight. Ok, ok, I'm getting longwinded here, what I want to ask is since they are considered quite common in the Northern Hemisphere, what are your experiences with them?? My hubby mentioned something about them being banded and the Tower of London. Can anyone help me here, an interested bird lover.
