Is this a nest?

I wonder... I saw it in one of the front yard's tree yesterday, and while there is no sign of a bird around there and the branch doesn't strike me as the ideal place to build a nest, as it is exposed to the weather and potential predators, it sure looks like a nest. Maybe it is just a bunch of twigs that got there by the wind, but I think it is more likely an empty nest. So sadly, I will not see birds any time soon in it, but the nest in itself still looks quite nice. Interesting how the natural world can be so aesthetic, even it its smallest incarnations, like this nest or a spider web.
