I never noticed the feathers in front of a Swallow's eyes until I was processing some images today. It's an interesting adaptation. There is a series of feathers (black in Violet-green and Tree Swallows) in front of the eye that look as if they're adapted to shield the eye from debris in their acrobatic flights. Possibly they also help disguise their eyes from flying insects to make it easier to catch them.
In either case it really looks cool at the right angle.
