In OB all you had were the biggies, like deer and bears, you heard bird song, but saw no birds. In Skyrim, it would be cool to have birds you could try and shoot down, chickens, racoons, snakes, mice...that would be cool. Imagine running through a Skyrim meadow and all the sudden you disturb a flock of beutiful birds that flutter up around you. What about bugs? Butterflies, bees, all these would better the game!
