Buteo lineatus
There’s a nest right next to the Carderock parking lot, and I hear the birds often enough, but I seldom see them. And when I do, it’s never in time to raise the camera to get a clear shot while the subject is nearby. One of these days I will buy a more appropriate lens for long-distance shots, but in the meantime I have to make do with the stock 55mm lens and the crop function in Lightroom.
