You have a very interesting backyard. I saw my FOY many days ago and then they disappeared again. I almost missed the one in the photo because I'm so used to seeing White-throated sparrows everywhere that it has become my default position. Even though their respective posture is so different the eyes become jaded and unresponsive after a while. I heard what I assume is a Field sparrow this morning while walking through a hydro field. It didn't seem that far away but I still couldn't locate it. It's sort of a nemesis bird for me. Far fewer warblers this morning and they disappeared early. It was also cloudy again. By the time I hit the hydro field it was quite sunny and feeling hot. I think I might need to start wearing a wide-brimmed Tilly hat on sunny days instead of my camo cap. The question is ... will I find it?
