I found this bird flitting around the small brush pile in my back yard. It would favor the brush pile and adjacent well pit cover, flying back and forth for about a half hour. I managed to get great shots of this bird from a distance of about 15 yards with my 600mm lens (on the Nikon D500)
Although I managed to photograph two sparrow species I've never photographed before, it was a pretty crummy day. My 600mm lens began to have serious auto-focusing images right after I took the image of the Swamp Sparrow. I felt quite dejected after this happened, and decided to cancel the rest of my shooting day and head back to Dodge City. The northwest wind behind the front in the morning was also a bit stronger than I was hoping for, so the combined events left me in a pretty sour mood. Nevertheless, it was good to at least partially get what I was after, even if the quality of the images were less then stellar. Onward!
