This is the last photo in which anything appears on this day. It appears that the bird is flying away. The following day, after I found so many photos that did not contain anything other than long grass blowing in the wind, I set the camera to a lower sensitivity level. The wildlife camera is triggered to take a photo by a combination of movement and body heat, so my guess is that, located here in the open, as opposed to previous forested locations, the sun may have provided the heat that the camera interpreted as body heat, and the wind blowing the long grass provided the movement.
