I know why they wore hoods

Standing upon the frosty ground, peering east through the ice fog at the golden glow intensifying over the distant tree tops, I begin to hail the sunrise of a new day. A sound, distant at first, but quickly becoming louder, the clicking of grackles and the trilling "Good Moooorning!" of the Red-winged Blackbirds as wave after wave of mixed flocks flew over head. I quickly raised the hood of my hooded sweatshirt, being an unfortunate victim of aerial assault before. A hood is a handy thing to have attached, which was why they were worn on the capes and cloaks of a by-gone age. It helps to retain body warmth. It can hide your face in shadow, if you prefer to be discrete, and it protects ones noggin from gifts from above.
