Ed and Reub and I were out walking in a rolling, brushy open place here in western Oregon when I was mesmerized by a pair of hovering birds. They were like smallish hawks hovering high above the hillside, then dropping straight down to get something in the grass. Flycatchers flying that high? King birds, slightly out of their usual countryside? They were silhouetted against the sky, so it was difficult to see markings, but I thought there might be a yellow cast on the belly of one. A king bird? Just not sure because I've never witnessed this hawking behavior before in anything but a hawk.
