I got too close to this Barn Swallow’s nest for its comfort, so it repeatedly swooped to warn me away. The first several swoops were quite startling because it silently and rapidly flew directly at me from in front, from the side, from behind. Within only a few feet of me it veered away as it gave (what I presume is) its alarm cry.
I captured this image as it veered, only a little farther from me than my arm can reach. A beautiful bird.
