The ancients must have thought a perfect portrait came from a bird looking over its shoulder. It's a classic. They always remind me of serious yearbook photos. This one could be titled "most likely to never have sense of humor and kill her husband if he gets out of line." Don't laugh, many raptors have smaller males just for that reason. The harrier happens to be one of those. :)
