Yellow Warbler

This gal was flitting around in this bush, giving me a second or at most 2 seconds before she flitted off to a new spot. The only way I could photograph her was to get her in focus at the last nanosecond just before she flew to a new perch, and then follow her there. Fortunately she spent a few minutes in the same bush to allow me to perfect, or at least succeed with this technique. Siskiyou County, California
