Finches are pretty flighty and don't stay put very long. That made a tripod impractical so I handheld, shot like crazy and hoped for the best. Other than a few twists of the f-stop, I didn't have much time to make adjustments, just had to take what I got!
This finch pair visited my cholla cactus several days in a row, apparently considering it as a nesting site. They wound up chosing a different location, but I enjoyed them while they were here.
