There was an interview in which was stated something called "Eagle Eye" or "Eagle Sight". Can't remember the specifics, neither do I have a source anymore :-( But my guess is that Connor will start out with a minor "Eagle's Sight" and that it will develop throughout the game towards "Eagle Vision" and "Eagle Sense".
