It centers on two bald eagles. It pans around to show them in their nest or on nearby branches. Sometimes (like right this moment) they can't even be seen because they flew off somewhere. I still watch and listen. I have it on one of my screens at work while I work on the other screen. Even when they're not there the sounds of the wind and other birds and occasional traffic is soothing. I think I'm kind of a junkie now.

If I understand right, they've been doing this for a number of years. If you keep watching, you'll get to see the eggs and the eaglets as they hatch. I'm pretty excited about that.
