I have been spending much of my time going over my photos. I seek to identify birds that were unknown. I look for errors I may have made in identifications. Ruddy-ground doves vs. Common Ground Doves. White-winged Doves vs White-tipped Dove, and the various stripes of Flycatchers. As I gain more knowledge, subtle differences seem more obvious.
